# Introduction Algem is a native liquid staking DeFi dApp on top of Astar Network and Soneium offering new ways for ASTR users and holders to earn more.
Algem is developed on two main features offering different solutions for users to stay liquid with their assets (ASTR and other tokens): — Liquid Staking; — Liquid Farming. # Liquid Farming The Liquid Farming concept is a successor to the liquid staking concept with one signicant difference: Liquid Farming allows users to remain liquid while participating in farming on AMM pools. It introduces new possibilities and strategies for liquidity providers, which will be further discussed in this paper. Algem’s Liquid Farming introduces a novel approach to liquidity provisioning and farming on the Soneium. By enabling users to remain liquid while participating in AMM farming activities, this innovative product significantly enhances flexibility, incentivization, and revenue opportunities for liquidity providers. ### Key Features of Liquid Farming 1. **lfETH Token Mechanism** * **Liquid Representation**: lfETH functions as a liquid derivative of ETH, providing users the ability to claim their underlying assets upon vault expiration. * **Utility and Flexibility**: Users can utilize lfETH in multiple ways, such as trading on AMMs, leveraging as collateral, or hedging their positions. 2. **Enhanced Rewards System** * **ALGM Incentives**: Users earn proportional ALGM rewards based on their staking contributions. * **Dynamic Farming Rewards**: By staking ALGM tokens in dedicated pools, users can maximize their farming rewards. 3. **Flexible Participation Options** * **Vault Selection**: Users can choose from multiple vaults with varying expiration dates and incentive structures. * **Early Liquidity Access**: lfETH enables liquidity providers to trade or utilize their assets without waiting for vault expiration. ### Advantages Over Traditional Farming 1. **Continuous Liquidity** * Unlike traditional farming mechanisms, Liquid Farming ensures that users maintain liquidity through lfETH tokens, allowing them to adapt to market changes. 2. **Hedging Opportunities** * By selling lfETH, users can mitigate potential losses if the price of ETH declines, providing a unique hedging mechanism. 3. **Simplified Rewards Distribution** * Rewards are distributed in ERAs and can be claimed manually, offering predictable and transparent earnings for participants. ### Core Mechanics and Flow 1. **Liquidity Provisioning** * Users supply ETH and ERC20 tokens to Algem’s supported AMM pools and receive LP tokens. * LP tokens are locked into vaults, where corresponding lASTR tokens are minted. 2. **Dynamic Reward Allocation** * Farming rewards depend on a balance between a user’s staked ALGM and their share of LP tokens, with the weighting shifting progressively towards ALGM staking over time. 3. **Liquidation Safeguards** * A built-in liquidation mechanism ensures a 1:1 ratio of ETH to lfETH, protecting users from imbalances and securing their initial investments. ### Revenue Model and Tokenomics 1. **Fee Structure** * Algem charges a 10% fee on farming rewards, contributing to the ALGM staking pool and supporting the platform’s sustainability. 2. **ALGM Token Utility** * ALGM plays a central role in farming mechanics by reducing token velocity and establishing consistent demand through staking pools and governance. ### User Benefits 1. **Maximized Earnings** * Liquid Farming provides additional rewards through ALGM incentives and trading opportunities with lfETH tokens. 2. **Improved Flexibility** * Users can adjust their strategies dynamically by trading or utilizing lfETH while maintaining eligibility for rewards. 3. **Sustainable Ecosystem** * The innovative mechanics ensure long-term demand for ALGM and attract sustainable liquidity to AMM pools. # FAQ #### What is Liquid Farming? Liquid Farming is a new product that allows users to stay liquid while farming on automated market maker (AMM) pools. It expands the concept of liquid staking, but with a focus on farming, offering new opportunities and strategies for liquidity providers. #### How is Liquid Farming different from Liquid Staking? Liquid staking usually involves staking tokens (e.g., ETH) to secure the network and earn rewards, whereas Liquid Farming is about providing liquidity to AMM pools and earning farming rewards. Users receive liquid tokens (lfETH) that can be used or sold before the vault expiration date. #### What is a vault in Liquid Farming? A vault is a smart contract that distributes rewards and mints/burns liquid tokens (lfETH). Each vault has an expiration date, after which deposits become unavailable, and lfETH holders can redeem their ETH. #### What is vault expiration? Vault expirations last for 4-6 months and are a preset date when a vault stops operating. When this happens: * Deposits are no longer accepted or modified. * lfETH holders can withdraw their ETH at a 1:1 ratio (one lfETH = one ETH). * Users can claim their assets, including ETH (if they have lfETH), accumulated rewards, and ERC20 tokens. * Before expiration, users can freely use their lfETH—trade it, use it as collateral, or hold it to redeem ETH later. * After expiration, lfETH is burned upon ETH withdrawal, and users receive their base assets. #### What is lfETH and how does it work? lfETH is a liquid ERC20 token, unique to each vault. It represents the right to claim ETH after the vault expires and can be used in various ways before that—trading, collateral, or holding for future ETH redemption. #### What is an ERA? An ERA is a time unit within the vault, currently set to one day. Rewards are distributed at the start of each ERA and must be manually claimed by the user. #### How to participate in Liquid Farming? To participate: * Provide ETH and an ERC20 token in a pair via the Algem interface. * Assets are sent to an AMM and farming rewards will start accumulating. * Upon deposit, the vault mints lfETH equal to the amount of ETH provided. #### What assets do I need to provide? You need to provide ETH and an ERC20 token, which together form a supported pair on an AMM. #### How do I choose a vault? Vaults vary by expiration date and ALGM incentive rewards. Typically, longer-term vaults offer higher incentives. #### Can I use my lfETH before expiration? Yes, you can: * Add it to the ETH/lfETH pool to earn trading fees. * Use it as collateral in lending dApps. * Hold it until expiration. * Sell it without affecting farming rewards. #### What happens if I sell some lfETH? If you sell 20 out of 100 lfETH, you will receive 80 ETH after expiration. The 20 lfETH sold will go to the withdrawal pool, available for other holders. #### What types of rewards will I earn? You can earn three types of rewards: 1. ALGM incentives, distributed based on your liquidity share. 2. Farming rewards from trading fees in the AMM pair. 3. Income from using lfETH, such as trading or collateralization. #### How are ALGM incentives calculated? ALGM rewards are calculated based on your share of liquidity relative to the total liquidity in the vault. #### How are farming rewards distributed? Farming rewards depend on: * Your ETH-ERC20 liquidity share in the vault. * Your share of ALGM in the staking pool. * Weight parameter "a", which increases over time, making ALGM staking more influential in reward distribution. #### What role does the ALGM staking pool play? The ALGM staking pool allows users to stake ALGM tokens to boost their share of farming rewards. Over time, as the "a" parameter increases, this pool becomes more important for maximizing rewards. #### How does the "a" parameter affect my rewards? The "a" parameter starts at 0 and increases linearly with each ERA, reaching 100% by vault expiration. * Early rewards are primarily based on liquidity share. * Over time, ALGM staking has a larger impact on rewards. #### What is the liquidation mechanism? The liquidation mechanism maintains a 1:1 ratio between ETH and lfETH. If the ETH balance in the vault drops below a threshold, liquidation occurs. #### What happens to my assets during liquidation? During liquidation: * The vault withdraws ETH and ERC20 from the AMM pool. * The ERC20 token is swapped for ETH to maintain the ETH balance. * lfETH tokens are burned in proportion to the amount of ETH recovered. #### Are there any fees or penalties for liquidation? No, there are no fees or penalties for liquidation. #### How can I maximize my farming rewards? To maximize rewards: * Stake ALGM rewards in the staking pool. * Since the "a" parameter increases over time, ALGM staking becomes more important for higher rewards. #### What happens if I don’t stake ALGM in the staking pool? If you don’t stake ALGM, you will gradually lose a portion of farming rewards, as the "a" parameter increases each ERA. #### What can I do with my lfETH? You can: * Add it to the ETH/lfETH pool for trading fees. * Use it as collateral in lending dApps. * Hold it until expiration to redeem ETH. * Sell it on AMM markets. #### How does selling lfETH help with hedging? Selling lfETH allows you to hedge against a drop in ETH price. If ETH price falls before expiration, you can profit from selling lfETH earlier (see [whitepaper](https://github.com/AlgemDeFi/White-Paper) for details). #### What benefits do external buyers of lfETH have? External buyers can: * Buy lfETH at a discount compared to ETH. * Hold lfETH until expiration to redeem ETH. * Trade lfETH on AMMs for potential profits. #### Can I withdraw my assets before expiration? Yes, you can close your deposit early, receiving: * Remaining ERC20 tokens. * Accumulated ALGM rewards. * Farming rewards. #### What fees does Algem charge? Algem charges a 10% fee on farming rewards, which is distributed among ALGM stakers. #### What risks are associated with Liquid Farming? Risks include: * Price fluctuations in AMM pools (impermanent loss). * Potential liquidation if ETH balance falls below a set threshold. # Liquid Farming Guide ### **Welcome to Liquid Farming!** Liquid Farming offers an innovative way to earn rewards by supplying liquidity to selected pools.

Built on the Astar Network, the revamped system addresses key limitations of its predecessor while introducing innovative mechanics to enhance user experience, security, and integration with decentralized finance (DeFi) ecosystems. ### Key Innovations in Liquid Staking V2 1. **Reward-Bearing Architecture** * **xnASTR Token**: Replacing nASTR, the new liquid token, xnASTR, adopts the Chainlink CCIP format to enable cross-chain compatibility and seamless use in various DeFi applications. * **Dynamic Value Accumulation**: xnASTR automatically accumulates staking rewards, eliminating the need for manual claiming. 2. **Enhanced User Flexibility** * **Multiple Unstaking Options**: Users can choose between regular unstaking (10-13 ERAs wait), immediate unstaking with a 1% fee (subject to reward pool availability), or trading xnASTR on Automated Market Makers (AMMs). * **Cashback System**: NFT-based discounts allow users to reclaim a portion of the staking management fees. 3. **Improved Integration and Usability** * **Cross-Chain Compatibility**: The Chainlink CCIP token format enables seamless cross-chain compatibility and integration with DeFi platforms. * **Voting Mechanism**: Stakers can allocate their ASTR to specific dApps using veALGM tokens, empowering community-driven decisions. 4. **Scalable and Secure Architecture** * **Elimination of Adapter Contracts**: The new architecture minimizes security risks and improves scalability by removing the reliance on adapter contracts. * **Compounding Rewards**: Staking rewards are periodically re-staked to enhance annual percentage returns (APRs). ### Addressing V1.5 Limitations 1. **Low Incentives for AMMs**: The absence of inherent trading incentives in nASTR pools is addressed by the reward-bearing design of xnASTR, fostering increased activity on AMMs. 2. **Limited Cross-Chain Usability**: The transition to CCIP format enables interoperability across unlimited number of chaines. 3. **Security Risks**: Adapter contracts, a scalability bottleneck in V1.5, are eliminated in V2’s design. ### Revenue Model and Tokenomics Algem’s Liquid Staking V2 introduces a sustainable revenue model: * **Fee Structure**: A 10% fee is charged on staking rewards and allocated to ALGM token stakers. * **Governance and Incentives**: veALGM tokens empower users to participate in governance and influence the allocation of staking rewards across dApps. # xnASTR To achieve the mentioned goals, a rewards-bearing architecture has been chosen with xnASTR as a liquid token. The "x" in xnASTR denotes its cross-chain nature due to its XC20 format. This mechanism eliminates the need for manual claiming of staking rewards; instead, they accumulate on the liquid staking contract, and the xnASTR/ASTR ratio steadily increases over time. The xnASTR price is determined by the following equation:
**stakedASTR**: the whole number of ASTR staked; **rewardPool**: a pool where all staking rewards are accumulated. Additionally, it is used as the fund for the immediate unstaking function. **xnastrTotalBalance**: the whole number of xnASTR minted. ### Staking and xnASTR minting A user stakes their ASTR through the liquid staking form and receives liquid xnASTR tokens back. The number of xnASTR tokens to receive is determined by the following equation:
### Unstaking A user unstakes their ASTR through the liquid unstaking form. The number of ASTR tokens to receive is determined by the following equation:
# Liquid dApp Staking V1.5 (old) {% embed url="" %} **Liquid staking** is the first and primary feature of the Algem protocol that leverages the Astar network's dApp staking. Algem's liquid staking solution allows users to continue to earn dApp staking rewards and increase their revenue by using tradable liquid nASTR tokens. The goal of liquid staking is to solve problems such as liquidity and the efficiency of fund usage. Users constantly face a choice: protocol staking or farming/liquidity mining in dApps, and this solution allows users to obtain the preferences of both ways simultaneously. With the version 1.5 of Liquid Staking, Algem adopts the dApp Staking philosophy a bit more by supporting multipools and allowing users to decide on which project they want to stake their tokens. {% content-ref url="/pages/64KjuuMIgR9FmgQakNKY" %} [ASTR Liquid Staking](/algem-protocol/liquid-dapp-staking/astr-liquid-staking) {% endcontent-ref %} {% content-ref url="/pages/3gAAPN1sPMhKR65wkaSG" %} [Unstaking nASTR](/algem-protocol/liquid-dapp-staking/unstaking-nastr) {% endcontent-ref %} {% content-ref url="/pages/KqmECTXkFtysBawpIR5h" %} [Liquid staking FAQ](/algem-protocol/liquid-dapp-staking/liquid-staking-faq) {% endcontent-ref %} **See our step-by-step guide to Liquid dApp Staking with Algem:** {% content-ref url="/pages/sTl4vg1RZgHQuKLofUWD" %} [How to use Algem's Liquid dApp Staking V1.5 (old)](/get-started/how-to-use-algems-liquid-dapp-staking) {% endcontent-ref %} # ASTR Liquid Staking When users deposit their ASTR tokens on Algem's liquid staking feature, they receive the same amount in nASTR tokens in return (1:1 ratio). ![](/files/RjraL3ADv2on0wGflaIC) Deposited ASTR tokens are delegated by Algem's smart contracts directly to the Astar network's dApp Staking and begin earning staking rewards. Algem collects these rewards and distributes them, minus a small fee ([more information about our fees](https://docs.algem.io/algem-protocol/protocol-revenues)), to users based on the nASTR balance in their wallets. Algem tracks all types of nASTR tokens, including base tokens, LP tokens, etc., which means that nASTR holders can use their tokens on other defi protocols through the nASTR Farming and still earn rewards. Staking reward is distributed according to the current dApp staking APR and rules. In addition, users can claim rewards on Algem after each new era. With Liquid dApp Staking, ASTR holders can choose the dApp they want to stake on and thus support in dApp staking. When a user decides to deposit his ASTR tokens on one of the dApps available in Liquid Staking, Algem's smart contracts directly transfer the ASTR tokens to the Astar network's dApp Staking and stake them on the corresponding dApp. In this way, Algem maintains and shares Astar Network's vision of creating a sustainable ecosystem where dApps and users collaborate and support each other for the benefit of the ecosystem. # nASTR ### Introduction to nASTR nASTR is a Liquid Staking Derivatives (LSD) token derived from Algem's Liquid dApp Staking mechanism. nASTR allows users to stay liquid with their ASTR tokens and earn additional rewards across Astar Network's Defi ecosystem. nASTR tokens are a liquid representation of ASTR tokens and are guaranteed by a 1:1 ratio. Each time a user deposits or stakes ASTR via the liquid staking solution, the Algem protocol mints an equal amount of nASTR tokens. These tokens represent the user's share and rights to claim the underlying tokens. Users can use nASTR in Algem's Liquidity Hub on partner dApps (for staking, lending/borrowing, LP, etc.) ### ASTR:nASTR ratio The ASTR:nASTR pair on DEX aims to stay equal, but the market may decide otherwise. However, to keep the ratio as close to 1:1 as possible, nASTR or ASTR holders can take advantage of arbitrage opportunities and earn more income while keeping the pair stable. If the ASTR:nASTR ratio decreases from 1, traders can sell their nASTR tokens for ASTR tokens and stake them back on Algem. They will end up with more nASTR than before the action. Suppose the ASTR:nASTR ratio increases from 1. Then, traders can buy nASTR tokens using ASTR tokens and unstake them on Algem using the regular unstaking or the immediate unstaking options. In that case, they will end up with more ASTR than before the action. ### nASTR ecosystem During our future iteration, we will concentrate on developing the infrastructure to use nASTR inside Algem. We call it the nASTR market with these use cases: Buy or sell nASTR; Use nASTR as a collateral. Users can take loans against their nASTR if they think they can use their credit money more efficiently than a loan percentage rate; Swap (our AMM). # Unstaking nASTR To get their ASTR back, nASTR holders must return their tokens to Algem using one of the two unstaking options available: ### **Regular unstaking** The regular unstake option uses the same function as the dApps staking of Astar Network. Once a user has unstaked his nASTR tokens, Algem triggers the unstaking on Astar dApps Staking. After the end of the unstaking period, Algem will receive the ASTR tokens and distribute them directly to the user's wallet. ### Immediate unstaking In the Immediate unstaking option, the user can decide to unstake his nASTR and receive his ASTR tokens directly without waiting for ten eras, as in the case of regular unstaking. In return, Algem charges a small fee for the service. [More information about our fees](https://docs.algem.io/algem-protocol/protocol-revenues). This option also depends on the capacity of the unstaking pool. The pool contains a certain amount of ASTR tokens. The system will deny the transaction if the pool is empty or does not have enough tokens to meet a user's unstaking request. Protocol revenues supply the pool, and so does the regular unstaking of immediate users. I.e., if a user immediately unstakes his nASTR tokens using the unstaking pool, he will receive his ASTR tokens directly from the pool. Still, Algem will also trigger the regular unstaking option in dApps staking. After ten eras, ASTR tokens from dApp staking will be added and fill the pool allowing other users to immediately unstake. The operation is the same in both options, only the time and fee change. The ASTR received after unstaking is not the initial deposit but the amount of unstaked nASTR. I.e., If a user has bought or sold nASTR tokens since his first deposit and has unstaked his entire balance of nASTR, he will receive more or less ASTR tokens than his initial deposit. ### Q: What is the unstaking period? Unstaking period varies from 10 ERAs to 13 ERAs (approximately 10-13 days). ### Q: Why so? In the Astar Network dApp staking unstaking period is 10 ERAs DApp staking has a limit of 4 unbonding calls/user during the 10 days. Since our liquid staking contract is basically a user, Algem groups all unbonding calls into bunches and sends them to the dApp staking 4 times/10 days. That is why If you unstake ASTR at the beginning of this cycle, your unstaking period will be 13 ERAs. **See our step-by-step guide to unstake your nASTR:** {% content-ref url="/pages/sTl4vg1RZgHQuKLofUWD" %} [How to use Algem's Liquid dApp Staking V1.5 (old)](/get-started/how-to-use-algems-liquid-dapp-staking) {% endcontent-ref %} # Liquid staking FAQ **Q: What is liquid staking?** Community members can participate in the Astar Network dApp staking via our liquid staking solution. Users will receive nASTR tokens (A liquid representation of the staked ASTR), use them inside Algem or partner dApps, and continue to receive their staking reward. **Q: How does it work?** When staking your ASTR with the Algem liquidity staking, users receive nASTR tokens on a 1:1 basis. Users can use their new nASTR tokens for yield farming, lending rewards, etc. nASTR holds a 1:1 peg to ASTR. Therefore dApps can implement the same use cases for this token and increase their liquidity. The protocol distributes staking rewards according to the current dApp staking APR and rules. **Q: How do you count dApp staking rewards?** Our protocol counts dApp staking rewards according to the number of nASTR you have and the current APR. **Q: What if I sell a part of my nASTR?** You will lose the same part of the dApp staking reward because you will lose rights on the underlying ASTR. **Q: When I use nASTR for farming/lending in the nASTR Farming, will I continue to receive a dApp staking reward?** Yes. When you use it in the Farming section, you still have the rights to underlying ASTR and, therefore, on the dApp staking reward generated by these tokens. **Q: How long is one era on Astar Network?** One era on the Astar network corresponds to 7200 blocks. The Astar network produces one block every 12 seconds, so one era lasts almost 24 hours or one day. See the Astar documentation or the portal for more information. **Q: How to claim the dApp staking reward?** Log in on Algem via MetaMask and claim your reward. **Q: What is the unstaking period?** Unstaking period varies from 10 ERAs to 13 ERAs (approximately 10-13 days). **Why so? In the Astar Network dApp staking unstaking period is 10 ERAs** DApp staking has a limit of 4 unbonding calls/user during the 10 days. Since our liquid staking contract is basically a user, Algem groups all unbonding calls into bunches and sends them to the dApp staking 4 times/10 days. That is why If you unstake ASTR at the beginning of this cycle, your unstaking period will be 13 ERAs. **Q: What if I buy nASTR on DEX or send nASTR tokens to my other wallet?** Your address, where you hold nASTR tokens, will start to receive the dApp staking reward. Also, you can claim underlying ASTR anytime on Algem. **Q: When can I claim my ASTR back?** Anytime via the unbonding form. At this moment, the protocol will burn your nASTR tokens. **Q: Is nASTR sufficiently backed by ASTR?** Yes. nASTR tokens are minted at the 1-1 basis at the moment of staking and burning at the moment of unstaking. nASTR supply is controlled by nDistributor smart-contract and the only way to mint new nASTR is to stake ASTR through the liquid staking form on Algem app. # nASTR Farming The nASTR Farming – which we previously referred to as nASTR Liquidity Hub – is a group of **intermediate contracts** that improve the user experience by allowing nASTR holders to interact with other protocols to use their nASTR tokens directly on Algem.
nASTR farming contracts receive $nASTR tokens and then proxy the actions to the selected protocol. Once locked in the contract, the balance cannot be changed unless removing the liquidity. Users can transfer tokens into the nASTR farming contract through a single transaction improving at the same time the user experience by avoiding to switch to different website to use various Defi protocols. Using nASTR Farming and directly on Algem, nASTR holders can: * Provide nASTR liquidity and stake LP tokens on AMM Standard and Stable Protocols. * Lend nASTR tokens to lending and collateral platforms. * Claim and receive farming rewards ⚠️ **Warning:** It is extremely important to use the adapters developed by Algem when using nASTR tokens with other Defi protocols in order to continue receiving staking rewards. \ If you use nASTR tokens directly on partner applications such as Arthswap, Sirius Finance, Kagla Finance or Sio2 Finance, you will no longer receive staking rewards. ### What is the benefit of the nASTR Farming * **Flashloan protection via the buffered implementation:** Several improbable scenarios exist when staking rewards can be boosted retroactively through the LP tokens. For example, a user can use a flash loan to claim the rewards and receive significantly more that way, returning the LP tokens at the end of the transaction. This risk will rise in the future when more Defi dApps propose flashloan services. * **Protection from LP manipulations:** Some bots could monitor the mempool and switch tokens between their accounts in an attempt to artificially increase their reward amount. * **Improved user experience such as:** * Users no longer need to visit multiple websites to add their tokens to an additional dApps; * Users require fewer actions for the whole process of depositing and withdrawals of tokens; * Users can read all of the balances in one place; * In the future, users can choose the DEX they want to interact with and see the statistics through Algem directly. - * **Calculation:** More precise reward calculation and higher platform security for users. * **Security:** Protection from the possibility of draining funds from or bankrupting the LP-provider contract. * **Supporting more protocols:** Not all dApp can support $nASTR for technical reasons. Among these are dApps such as AstridDAO and Arthswap, important for the Astar ecosystem.

Following Astar Network's values, we decided not to make any of our governance tokens available for sale to the community. At Algem, we believe that it's best to distribute ALGM only to users and supporters of our project. *Therefore, the only way to receive governance tokens before being listed on exchanges is to lock ASTR or get an airdrop.* # Tokenomics **Token Ticker:** ALGM \ **Decimal:** 18 \ **Total Supply:** 100,000,000 \ **Token Address:** TBD ### ALGM - governance token ALGM is the governance token of the Algem Protocol. Users can have rights and voting powers by holding and using the ALGM token on our platform. ### **ALGM's allocation** | Title | Percentage | Detail | | ----------------------- | ---------- | ------------------------------------------------------------------- | | Incentives | 50% | Over 6 years | | Team | 18% | 6-month cliff after launch, and 3-year vesting with monthly release | | Early Investors | 15% | 6-month cliff after launch, and 2-year vesting with monthly release | | Community growth | 7% | Marketing, events, additional incentives; | | Reserve | 8% | Unexpected expenditures, etc. | | Airdrop | 2% | Testnet participants, early members, dApp staking. | | Algem Nautilus Pass NFT | 0.5% | 6 month cliff after the launch and 1 year vesting. | ### **ALGM's distribution schedule** ![](/files/HyZH1O86N0I6rEuVnj16) ### **ALGM's airdrop** We have allocated 2% of the ALGM supply to reward our early supporters and users during the initial phase of Algem. To obtain these rewards, users must participate and help develop Algem by testing our product, suggesting improvements, or contributing to our protocol and community. # ALGM Utility **ALGM** is Algem protocol’s governance token and has numerous functionalities. The purpose of this section is to examine these core functions. Before we begin, it bears mentioning that the only way for users to receive ALGM is by depositing ASTR or other tokens in a vault. There is no pre-mine or ICO. In other words, users must partake in Liquid Farming in order to begin earning ALGM. Furthermore, ALGM gives users the rights to: * *Earn by depositing* to Algem’s DeFi partner dApps and receive additional earning incentives * *Earn by staking* ALGM to the Algem protocol and to share in its revenues. * *Vote and make decisions* regarding a dapp's future (e.g., add a new vault) and set parameters such as fees, vault weights, etc. ### **Additional ALGM Functions: Voting** #### Voting for dApps via Liquid Staking Users can vote for dApps in Astar dApp staking to stake ASTR via Algem's liquid staking solution. #### Voting for app features and upgrades Voting on upgrades (add a new vault, change dApp parameters and fees, etc.) # NFT Collections Algem is the first project on Astar network to experiment with NFT collections and Defi services. Owning one or more of our NFTs gives its owner advantages over Algem's Defi products, such as discounts on fees, increased APR, access to private groups and other gifts. Algem currently has three NFT collections: * Algemantis * Liquid Staking Discount * Algem x Archiverse Dojo ## Algemantis NFT Collection

This NFT was offered by Algem to reward all the users who completed the campaign #AlgemDojoContest. The DOJO has been fully developed and modeled in 3D with reference to Algem and Astar’s colors. The building takes its archetype from traditional Japanese craftsmanship while adding neo-futuristic elements to generate a new spatial and visual experience. The space offered within the dojo is thought of as being, a practice area, a place where you meditate, repeat exercises and celebrate learning. It will allow you to remember your participation in the Algem event. Along with the #AlgemDojoContest campaign, you perfected your art by completing different quests in order to discover Astar decentralized ecosystem and Algem application. As of now, you have your personal DOJO which will forever bring back memories of this special time of learning and intimate development. It will allow you, in turn, to transmit the knowledge you’ve learned while bringing in new users. *Developed and built by Archiverse ([www.archiverse.art](http://www.archiverse.art))* **NFT contract name:** Algem Dojo\ **NFT contract address:** [0xeBdA851087FF6A75961781987B9f1F7832D9DeB0](https://blockscout.com/astar/token/0xeBdA851087FF6A75961781987B9f1F7832D9DeB0/token-transfers)\ **Supply:** 160 AD Algem x Archiverse Dojo NFT can be traded on the secondary market on Bluez or Tofu NFT : \ # Protocol revenues Algem protocol revenues come from two different sources: * **Fees.** In return for its services, Algem charges a small fee for its various features: * Liquid Staking management fee (10% fee on staking reward) * Immediate unstaking fee (1% on the unstaking amount) * Liquid Lending management fee (10% fee on lending reward) * nASTR Farming fee (10% fee on partner's farming reward) * **Build2Earn reward.** Algem is part of the Astar Builders program. As a result, Algem generates operator rewards from Astar dApp Staking during each Astar era through its pool on the Astar portal. Users can follow the reward distribution on Subscan. ### Revenue distribution #### Before the Liquid Farming launch (current stage) * 90% of the whole revenue goes to the team; * 10% of the whole revenue goes to the immediate unstaking pool ([more information about immedial unstaking here](https://docs.algem.io/algem-protocol/liquid-staking/unstaking-nastr)). #### After the Liquid Farming launch * 70% of the whole revenue goes to the [ALGM stakers as a reward](https://docs.algem.io/algem-protocol/algm-token/algm-utility#algm-staking-and-reinvestment-in-corresponding-pools); * 20% of the whole revenue goes to the team; * 10% of the whole revenue goes to the immediate unstaking pool. # Risk management Before using Algem, please read our [terms and conditions of use](https://www.algem.io/terms-of-use) and be aware of the risks. * **Smart contract risks.** \ \ Algem had its [protocol and smart contracts audited](https://github.com/AlgemDeFi/audits/blob/main/AlgemQuantstampCertifacate.png) by [Quantstamp](https://quantstamp.com/), leader in Web3.0 security. Be aware that a security audit does not guarantee the total infallibility of a protocol. Risks can always be present. Do not stake assets that you cannot afford to lose on Algem.
* **nASTR loss of peg.** \ \ On Algem protocol, there is always a ratio 1:1 for minting nASTR and returning it. No matter the ratio of the nASTR/ASTR pair on the market. Users can always redeem the same amount of ASTR from nASTR tokens. However if nASTR holders use their tokens in DEXs to provide liquidity, they face the possibility of impermanent loss and depeg like any farming in DEXs. \ \ To mitigate this risk, users can perform arbitrage strategies between DEXs and Algem protocol using swap, stake and unstake functions. In this way, users have financial incentives to keep the ASTR/nASTR peg and stabilize the ecosystem. [See the nASTR:ASTR ratio section.](https://docs.algem.io/algem-protocol/dnts#astr-nastr-ratio)
* **Impermanent loss on DEX**\ \ **"**In essence, impermanent loss is a temporary loss of funds occurring when providing liquidity. It’s very often explained as a difference between holding an asset versus providing liquidity in that asset. Impermanent loss is usually observed in standard liquidity pools where the liquidity provider (LP) has to provide both assets in a correct ratio, and one of the assets is volatile in relation to the other, for example, in a Arthswap ASTR/WETH 50/50 liquidity pool.
If WETH goes up in value, the pool has to rely on arbitrageurs continually ensuring that the pool price reflects the real-world price to maintain the same value of both tokens in the pool. This basically leads to a situation where profit from the token that appreciated in value is taken away from the liquidity provider. At this point, if the LP decides to withdraw their liquidity, the impermanent loss becomes permanent." See "[What is Impermanent Loss? DEFI Explained](https://finematics.com/impermanent-loss-explained/)" from Finematics for more.

Algyors are the ambassadors of Algem through the universe of Dotsama, their mission is to promote our city and contribute to the growth and influence of Algem. They are also essential members of our community and our city, helping our citizens and visitors during their journey in Algem. Algyors are members of our community selected by the Algaris, the founders of the city. They work closely with the Algaris and are the liaison with the community to improve Algem all the time. ### Guidelines 1. The most important rule: always be polite, no matter what someone is writing you. A courteous approach always wins over rudeness and insults. 2. Be as accurate and short in your answers as possible. Time is a valuable currency, do not waste your and the user’s time. If the user asks you for a link, send him a link. If the user asks you for a release date, send him a date, etc. 3. Do not use “soon.” Soon doesn’t exist in our company’s vocabulary. 4. Do not answer the question if you don’t know the exact answer. Ask for assistance from somebody from the core team. 5. Do not answer the question if it was answered already. 6. Do not hide from unsuitable questions. E.g., token price, the release was postponed, etc. Communication and transparency always win. 99% of our users are everyday people, and regular people understand that sometimes things go out of the initial plan. They just want to know why. 7. Never use words like “dude”, “mate”, “man”, etc. We are not in a bar. 8. Encourage users to leave feedback about our product. Our users have to understand that their opinion matters and will be rewarded. 9. Identify Algem brand advocates. In web3, users tend to help without any payment. But our goal is not to use people but to stimulate them to spread information about our platform (video, tweets), create and manage local communities, etc. They have to know that their efforts will be rewarded by ALGM. 10. You can mute or even ban without warning users that violate the accepted rules of our community. Our goal is to keep communication in a polite and friendly manner. ### Ambassador Reward Program #### Missions & Criteria * Being an active community member * Understand and share the vision and goal of Algem * Help and answer the community in our social media and community channels (Twitter, Telegram, Discord) * Moderate our social media (Discord, Twitter) * Translate and publish news, content and important articles on community channels. * Promote Algem in other Polkadot and crypto communities. #### How does the program work? The program focuses on three main tasks for the ambassadors: 1. Provide help and support to users and moderate Algem's social networks (Discord & Twitter) 2. Translate into native language Algem news and updates shared in the announcement channel and publish them in the corresponding international community. 3. Each week, specific tasks will be assigned to Algyors that can range from specific translations (documentation, blog, app, etc) to local market research to conducting online workshops. At the end of each month, all Algyors will participate in a monthly call with Algem's core team to discuss Algem's goals and plans for the following month and share their feedback. Algyors will also fill out a monthly feedback form to self-assess their work and their community. The rewards for the Ambassador program are in nASTR & ALGM tokens and come from the community growth allocation and the dApp Staking developer rewards. #### Engagement: * Agree and accept [Algem’s rules](https://discord.com/channels/949531419619766332/994726247370334300/994727495263858708) and the ambassador guidelines. * Carry out daily and weekly assignments * Participate in the Monthly Algyors Meeting * Complete the monthly feedback and report. #### Compensation: Each month, Algem allocates 8500 nASTR & 600 ALGM tokens to each ambassador of the program until the listing of ALGM token on the market. After that, the reward will be only in ALGM tokens (amount can be changed depending on the market value of the ALGM). ### How to join the Algyors Program?

Just joining the community is NOT enough. If you are not active you will be denied as Ambassador. Please know if you submit your application, you agree that you are part as an active community member and you understand Algem.* # Roadmap ### 2023 - Stage 1: * Liquid dApp Staking v1.5 launch * nASTR Farming: SIO2 & Starlay Finance Integration * Secret project (Liquid & Cross-chain); * Liquid Lending; * ALGM staking; * ALGM launch and listing; * NFT holders ALGM airdrop; * ALGM token distribution ### 2023 Stage 2: * Algem’s governance; * Liquid staking V2; * Launch on Shiden; * Liquid staking multi-pools on Astar Native (Substrate); * nASTR XC20 - Cross-parachains assets on Polkadot's parachains ### 2023 Stage 3 * Algem liquid staking & liquid lending on other parachains; * Algem liquid staking & liquid lending on other EVM chains *Sequence and composition of the works in this roadmap can be changed for the purposes of Algem and ALGM holders’ success* # nASTR (V1.5 liquid token) ### Introduction to nASTR nASTR is a Liquid Staking Derivatives (LSD) token derived from Algem's Liquid dApp Staking mechanism. nASTR allows users to stay liquid with their ASTR tokens and earn additional rewards across Astar Network's Defi ecosystem. nASTR tokens are a liquid representation of ASTR tokens and are guaranteed by a 1:1 ratio. Each time a user deposits or stakes ASTR via the liquid staking solution, the Algem protocol mints an equal amount of nASTR tokens. These tokens represent the user's share and rights to claim the underlying tokens. Users can use nASTR in Algem's Liquidity Hub on partner dApps (for staking, lending/borrowing, LP, etc.) ### ASTR:nASTR ratio The ASTR:nASTR pair on DEX aims to stay equal, but the market may decide otherwise. However, to keep the ratio as close to 1:1 as possible, nASTR or ASTR holders can take advantage of arbitrage opportunities and earn more income while keeping the pair stable. If the ASTR:nASTR ratio decreases from 1, traders can sell their nASTR tokens for ASTR tokens and stake them back on Algem. They will end up with more nASTR than before the action. Suppose the ASTR:nASTR ratio increases from 1. Then, traders can buy nASTR tokens using ASTR tokens and unstake them on Algem using the regular unstaking or the immediate unstaking options. In that case, they will end up with more ASTR than before the action. ### nASTR ecosystem During our future iteration, we will concentrate on developing the infrastructure to use nASTR inside Algem. We call it the nASTR market with these use cases: Buy or sell nASTR; Use nASTR as a collateral. Users can take loans against their nASTR if they think they can use their credit money more efficiently than a loan percentage rate; Swap (our AMM). # nASTR Farming The nASTR Farming – which we previously referred to as nASTR Liquidity Hub – is a group of **intermediate contracts** that improve the user experience by allowing nASTR holders to interact with other protocols to use their nASTR tokens directly on Algem.
nASTR farming contracts receive $nASTR tokens and then proxy the actions to the selected protocol. Once locked in the contract, the balance cannot be changed unless removing the liquidity. Users can transfer tokens into the nASTR farming contract through a single transaction improving at the same time the user experience by avoiding to switch to different website to use various Defi protocols. Using nASTR Farming and directly on Algem, nASTR holders can: * Provide nASTR liquidity and stake LP tokens on AMM Standard and Stable Protocols. * Lend nASTR tokens to lending and collateral platforms. * Claim and receive farming rewards ⚠️ **Warning:** It is extremely important to use the adapters developed by Algem when using nASTR tokens with other Defi protocols in order to continue receiving staking rewards. \ If you use nASTR tokens directly on partner applications such as Arthswap, Sirius Finance, Kagla Finance or Sio2 Finance, you will no longer receive staking rewards. ### What is the benefit of the nASTR Farming * **Flashloan protection via the buffered implementation:** Several improbable scenarios exist when staking rewards can be boosted retroactively through the LP tokens. For example, a user can use a flash loan to claim the rewards and receive significantly more that way, returning the LP tokens at the end of the transaction. This risk will rise in the future when more Defi dApps propose flashloan services. * **Protection from LP manipulations:** Some bots could monitor the mempool and switch tokens between their accounts in an attempt to artificially increase their reward amount. * **Improved user experience such as:** * Users no longer need to visit multiple websites to add their tokens to an additional dApps; * Users require fewer actions for the whole process of depositing and withdrawals of tokens; * Users can read all of the balances in one place; * In the future, users can choose the DEX they want to interact with and see the statistics through Algem directly. - * **Calculation:** More precise reward calculation and higher platform security for users. * **Security:** Protection from the possibility of draining funds from or bankrupting the LP-provider contract. * **Supporting more protocols:** Not all dApp can support $nASTR for technical reasons.

Open the app 2. Navigate to “Settings” and confirm 3. Confirm the “Blind signing” option, so it turns to “Enabled” 4. Navigate to “Back” and confirm
## Use your Ledger EVM on Algem In our example, we will see how to stake ASTR tokens on Algem with a ledger device. Once you have configured your ledger, enabled smart-contracts and connected it to Metamask, you can connect your EVM ledger using Metamask to Algem dApp. It will work the same way as a normal Metamask wallet but you will need to confirm every action and transaction on your ledger device.
1. Enter the amount of ASTR token you would like to stake (minimum of 100 ASTR); 2. Confirm your action by clicking on the stake button. 3. Sign the transaction in your Metamask-Legder wallet. 4. Confirm the transaction on your ledger device 1. Blind Signing 2. Check amount 3. Check address (smart-contract) 4. Check fees 5. Approve the transaction
Once Algem has delegated your ASTR tokens to Astar dApp Staking, you will receive the same amount as the amount deposited in nASTR tokens and start earning staking rewards directly on your ledger address. You can add the nASTR token to Metamask by adding the following token address or using the dedicated feature in Algem dApp. ***nASTR:*** 0xE511ED88575C57767BAfb72BfD10775413E3F2b0
To use your nASTR tokens in Algem's nASTR Liquidity Hub, please choose one of the different projects available and follow the corresponding guide. The only difference will be to confirm each transaction using your ledger device as explained above. # Polkadot{.js} ### Install Polkadot.js Plugin To create a Polkadot.js, install the Browser Plugin available for both [Google Chrome](https://chrome.google.com/webstore/detail/polkadot%7Bjs%7D-extension/mopnmbcafieddcagagdcbnhejhlodfdd?hl=en) (and Chromium-based browsers like Brave) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/polkadot-js-extension/). \ \ After installing the plugin, you should see the orange and white Polkadot{.js} logo in your browser menu bar. ![](/files/61JK0JZRij4xRQJZE6bg) ### Create Polkadot.js Wallet Open the Polkadot{.js} extension and click on the + button - "Create a new account". ![](/files/BCUMZFIv90Q3wQVeKABp) Polkadot{.js} will randomly generate a new seed for you and display it as twelve words. **Save these words in a safe place.** ![](/files/5CBZcD1n707mm60W0NCu) Choose a descriptive name for your wallet and a password. You must enter your password a second time to confirm it. Congratulations, you have just created your first polkadot (native) substrate wallet! # Transfer assets to Astar Network EVM Astar Network uses two different but related networks, **Astar Substrate and Astar EVM**. The Astar portal is a gateway between those networks, and the portal uses ASTR tokens for gas fees. *If you need ASTR tokens to do a transaction, you can claim free ASTR on the Astar Portal or Astar Discord.* {% embed url="" %} **Algem is, at the moment, only deployed on Astar EVM.** Therefore, to use Algem, you must transfer assets such as ASTR tokens to your Astar EVM wallet. To do so, you have five options. 1. Withdraw from a CEX supporting Astar EVM 2. Transfer from Astar substrate to Astar EVM using the Astar portal 3. Use a bridge 4. Cross-chain swap assets 5. Buy ASTR tokens on a DEX. # From a CEX The Astar blockchain is divided into two chains: Substrate (**Native**) and Ethereum compatible (**EVM**). One supports wallets like [**polkadot.js**](https://polkadot.js.org/extension/), [Talisman](https://talisman.xyz/) (native) or [Subwallet](https://subwallet.app/) (native) and the other supports EVM wallets like[ Metamask](https://metamask.io/), [Talisman](https://talisman.xyz/) (EVM) or [Subwallet](https://subwallet.app/) (EVM). The role of the [Astar portal](https://portal.astar.network/#/assets) is to make the **link between these two chains** to transfer tokens, information or instructions. The token of the Astar Network blockchain is the **ASTR**. It is listed on [many exchanges](https://coinmarketcap.com/currencies/astar/markets/) (CEX or DEX). Among the centralized exchanges are **Binance, Kraken, OKX, Huobi, MEXC, Kucoin, and Gate.io**. If you want to send tokens from a centralized exchange (CEX) like Binance or Kraken to an EVM wallet, like Metamask, on the Astar EVM chain, you have two options: * **CEX supports withdrawals to the Astar EVM chain** * **CEX does not support withdrawals to the Astar EVM chain, only to the Astar Native chain.** ***Be careful, when you try a transfer for the first time, always test a first transaction with a small amount before sending all your funds!*** ### Sending ASTR from a CEX to Metamask using the Astar EVM network. At the moment, only 2 CEX support withdrawals directly to the Astar EVM network: **Gate and MEXC**. 1. To make a withdrawal, go to the "withdraw" section of your CEX (Gate or MEXC). 2. Select the ASTR token and choose the **Astar network EVM;** 3. Enter your EVM address where you want to receive your tokens (Metamask); 4. Choose the amount of ASTR you want to withdraw; 5. Confirm the withdrawal; 6. After a certain period of time defined by the CEX, your tokens will arrive directly in your EVM wallet.
### Sending ASTR from a CEX to Metamask that does not support the Astar EVM network. Most of the CEX mentioned above do not support the Astar EVM network, only the Astar Native network. To send tokens to Metamask, you will first have to send them to a native wallet (polkadot.js, Talisman or Subwallet) and then use the Astar Network portal to transfer them to your wallet on the Astar EVM network. 1. To withdraw, go to the "withdraw" section of your CEX; 2. Select the ASTR token and choose the **Astar Network**; 3. Enter your **native address** where you want to receive your tokens (Polkadot.js); 4. Choose the amount of ASTR you want to withdraw; 5. Confirm the withdrawal; 6. After a certain period of time defined by the CEX, your tokens will arrive directly in your native wallet;
7\. Once your tokens are in your native wallet, log in to the [Astar Network portal](https://portal.astar.network/#/assets); 8\. In the "Assets" section, click on the "Transfer" button on the ASTR token line;
9\. A window will open; 10\. Enter your **EVM address** copied from Metmask and choose the amount of ASTR you want to send; 11\. Confirm and sign the transaction in your wallet extension;
12\. After validation of the transaction on the blockchain, your tokens will be in your EVM wallet. More information in the Astar Network documentation: {% embed url="" %} # Using Astar Network Portal If you hold ASTR tokens in your substrate wallets such as Polkadot.js, Talisman, Subwallet, or others, you can transfer your tokens to an EVM wallet through the Astar Network Portal. 1. First, copy your EVM address (Metamask or Talisman) 2. Connect your substrate wallet to Astar Portal and click "transfer." 3. Past your EVM address and enter the amount of ASTR you want to send 4. Confirm the transfer Please visit the official Astar documentation for a completed guide for token transfer between substrate and EVM wallets. {% embed url="" %} # Using Bridges Suppose you hold ASTR tokens or other assets on EVM blockchains such as Ethereum, Binance, Avalanche, Polygon, or others. In that case, you can use one of the following bridgers to transfer your token to the Astar Network EVM chain. #### **cBridges:** {% embed url="" %} {% embed url="" %} #### **Anyswap:** {% embed url="" %} {% embed url="" %} # Using a cross-chain swap The last option is to use [**XY Finance**](https://app.xy.finance/) to cross-chain swap from 12 EVM chains to Astar Network. {% embed url="" %} XY Finance is a one-stop cross-chain swap aggregator for DeFi & Metaverse, allowing users to directly buy ASTR and other tokens on Astar from other chains in one transaction. Currently, XY Finance supports 12 EVM chains, including Ethereum, BSC, Fantom, Polygon, Arbitrum, Optimism, Avalanche C-Chain, Cronos, KCC, ThunderCore, Astar, and Moonriver. 1. Connect your EVM wallet to [XY Finance](https://app.xy.finance/), 2. Choose the asset and chain you want to use 3. Select the asset you wish to receive on Astar 4. Check the recipient's address 5. Confirm the swap Please visit the official Astar documentation for a completed guide on cross-chain swap using XY Finance. {% embed url="" %} # Using a DEX If you have other assets in your Astar EVM wallet, you can buy ASTR tokens directly from one of the DEX on Astar Network, such as [Arthswap](https://app.arthswap.org/#/swap) or [PolkaEX](https://app.polkaex.io/swap). # How to use Algem's Liquid dApp Staking V2.0 (new) Open the link: ### Liquid dApp Staking dashboard overview #### Header
1. Toggle between light and dark themes. 2. Switch between available networks: Astar and Soneium. 3. Disconnect the connected wallet. #### General Information about Liquid dApp Staking
4. TVL: Displayed in both ASTR and USD. 5. APR: Includes bonus rewards and re-staking of dApp staking rewards. 6. Immediate Unstaking Pool Size: If your unstake amount is less than the pool size, you can unstake tokens instantly without waiting for the unlock period. 7. Current ERA: On Astar Network, rewards are distributed once per ERA. One ERA equals 7,200 blocks or approximately 24 hours. #### Your Stake and Rewards Information
8. Stake Amount: Displayed in xnASTR. 9. Current xnASTR Price: Shown relative to ASTR. 10. Blocks until the price update: After the specified number of blocks, the next staking rewards will be distributed, increasing the price of xnASTR relative to ASTR. 11. Algem Discount NFT Holders: Eligible for cashback on staking management fees by locking their NFT. #### Staking/Unstaking Form
#### dApps available for Liquid Staking
Your ASTR tokens will be staked across the dApps listed below, in proportion to their staking weights. For example: dApp 1: the staking weight is 100 veALGM / 22,(22)% dApp 2: the staking weight is 150 veALGM / 33,(33)% dApp 3: the staking weight is 200 veALGM / 44,(44)% When a user stakes 1,000 ASTR, the distribution of their tokens among the dApps is as follows: dApp 1: 22,(22)% × 1,000 = 222.22 ASTR dApp 2: 33,(33)% × 1,000 = 333.33 ASTR dApp 3: 44,(44)% × 1,000 = 444.44 ASTR This works the same for unstaking. dApps available for Liquid Staking #### Initial dApps: * Algem * Astar Core Contributors * Astar Degens * Arthswap * NEET Astar Core Contributors and Astar Degens were added without voting due to their long-standing partnership with Algem. Arthswap and NEET were chosen through a two-stage voting process: 1. Preliminary voting on Algem Discord identified four finalists. 2. [Final voting was conducted on X](https://x.com/Algem_io/status/1877732179104739705). New dApps will be periodically added based on user votes conducted via veALGM after the ALGM token launch. ### How to use Liquid dApp Staking #### Network Selection and Wallet Connection
Go to the Liquid dApp Staking V2.0 page and select the network you want to stake on. * On Astar Network, you stake native ASTR. * On Soneium, you stake the ERC20 version of ASTR. To transfer ASTR from Astar to Soneium, use the [bridge on the Astar Network portal.](https://portal.astar.network/astar/bridge) #### Staking
* Select the staking window and enter the desired amount (minimum 100 ASTR), then confirm the transaction. * On Astar Network, staking requires a single transaction. * On Soneium, you need to first approve the token (setting a spending limit) and then confirm the staking transaction. Note: When staking on Soneium, ASTR tokens are sent to Astar Network and xnASTR tokens are returned. This cross-chain transfer is performed via Chainlink CCIP and may take up to 1 hour. In case of a failed transaction, your ASTR tokens will be returned to your address. After staking, your xnASTR balance will appear on the dashboard (tokens transferred to another address or used in DeFi apps will not be shown on the dashboard!). #### **Adding xnASTR to Web3 Wallet** Use the contract address below to add xnASTR to your wallet (same for Astar Network and Soneium): 0xea1e08A176528e2d7250a6F7001F18EDF0CaeCF0 In Metamask: ![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXcq6N6Iomjezk9ePpm_3q-1PNvhgobCnorVuyiwOA3sInFrKf6vkuGprxPhiPDR05iviVDi2_rtTVlG2L0ZHltBQZ2U9Ly2mGI9OB00FYNC5SqDRBHBnqdPULp42xyO2ZKxc6ldaQ?key=9Xqljv01pSU-g5INNQ4ujXdn) * Click the app icon in your browser. * Go to the Tokens tab. * Click the 3 dots tab select the Import tokens option. * Enter the contract address in the Custom Token field and import it into your wallet. #### Unstaking
* Click the unstake tab and enter the desired amount (minimum 100 xnASTR), then confirm the transaction. * On Astar Network, unstaking requires a single transaction. * On Soneium, you first approve the token (setting a spending limit) and then confirm the unstaking transaction. Two unstaking options are available here: * Unstake Immediately: If the Immediate Unstaking Pool has enough tokens, the "Unstake Immediately" button will be active, allowing you to withdraw instantly without waiting for the standard 10-ERA period (\~10 days). * Standard Unstaking: If the pool is insufficient or you prefer to wait, use the standard unstaking option (10–12 ERAs, approximately 10–12 days). #### **Withdrawing Tokens**
After initiating standard unstaking, the dashboard will display a new My Unstaking Amount field. Once this unstaking period ends, the Claim Tokens button will become active, allowing you to withdraw your ASTR tokens. # How to use Algem's Liquid dApp Staking V1.5 (old) Before using Algem's liquid dApp staking, read our technical documentation to understand the mechanism and concept behind the liquid staking {% content-ref url="/pages/Y0NJPZTstwRql5PqZeoI" %} [Liquid dApp Staking V1.5 (old)](/algem-protocol/liquid-dapp-staking) {% endcontent-ref %} Algem dApp is supported on both desktop and mobile version. {% content-ref url="/pages/uFn6lu4S4hJhVRSJfFK5" %} [Desktop version](/get-started/how-to-use-algems-liquid-dapp-staking/desktop-version) {% endcontent-ref %} {% content-ref url="/pages/tG8Cb785rzrukD6cPLsa" %} [Mobile version](/get-started/how-to-use-algems-liquid-dapp-staking/mobile-version) {% endcontent-ref %} {% embed url="" %} # Desktop version {% embed url="" %} ## Overview **Total ASTR Staked** -> Total amount of ASTR token staked on Algem Protocol\ **APR** -> Annual Percentage Rate calculated from current dApp staking APR and Algem rules\ **Unstaking pool** -> ASTR tokens available for immediate unstaking\ **My Staking amount** -> amount of nASTR in the user's wallet, including basic tokens, Lp tokens, or collateral tokens\ **All Rewards** -> Staking rewards to claim\ **Blocks until next reward** -> Blocks remaining until the next era and therefore until the subsequent reward distribution in the user's reward pool. ![](/files/yvRP8Pp7sYeHmkcaLITr) ## Guide: Once you have your ASTR tokens in your EVM wallet, you can go to the liquid staking section in Algem dApp and connect your EVM wallet. ![](/files/T19lRSMmGY4hP34geHIQ) ### **How to Stake:** * Enter the amount of ASTR tokens you want to deposit, (minimum of 100 ASTR) * Then select the dApp; * Confirm your action by clicking on the stake button. * Receive an equal amount of nASTR tokens and begin earning staking rewards. * Use nASTR tokens to farm on our partners Defi dApps in our [nASTR Farming](https://docs.algem.io/get-started/how-to-use-algems-nastr-liquidity-hub); ![](/files/XH75bKbXwG24BDYiRoEM) Once Algem has delegated your ASTR tokens to Astar dApp Staking, you will receive the same amount as the amount deposited in nASTR tokens and start earning staking rewards.

# How to use Algem's nASTR Farming The nASTR Farming – which we previously referred to as nASTR Liquidity Hub – is a group of **intermediate contracts** that replicate our DeFi dApps partners’ interface on Algem’s app. Once you have staked your ASTR tokens on Algem and received your nASTR, you can choose one of the available protocols where you want to use your tokens. At the moment, the four dApps supported by the Algem Adapter Contracts are Sirius Finance, Kagla Finance, Arthswap and SiO2 Finance. {% content-ref url="/pages/Ynx8G8wtfFKdthDof0UP" %} [Sirius Finance](/get-started/how-to-use-algems-nastr-farming/sirius-finance) {% endcontent-ref %} {% content-ref url="/pages/DPBNmnPyIXZXfGasJU6Q" %} [Kagla Finance](/get-started/how-to-use-algems-nastr-farming/kagla-finance) {% endcontent-ref %} {% content-ref url="/pages/kv8hvUsxVpbQkbG7BuiM" %} [Arthswap](/get-started/how-to-use-algems-nastr-farming/arthswap) {% endcontent-ref %} {% content-ref url="/pages/dt7zidiO1GloRij5dZn6" %} [SiO2 Finance](/get-started/how-to-use-algems-nastr-farming/sio2-finance) {% endcontent-ref %} ⚠️ **Warning:** It is extremely important to use the adapters developed by Algem when using nASTR tokens with other Defi protocols in order to continue receiving staking rewards. \ If you use nASTR tokens directly on partner applications such as Arthswap, Sirius Finance, Kagla Finance or Sio2 Finance, you will no longer receive staking rewards. **For all the users farming already with nASTR tokens on Sirius or Kagla Finance, you must stake your Gauge tokens in Algem’s nASTR Farming to keep earning staking rewards.** {% embed url="" %} ### How to provide liquidity and stake LP tokens * Choose a dApp in the [nASTR Farming section](https://app.algem.io/liquid-staking);

# Sirius Finance [Sirius Finance](https://www.sirius.finance/) is a Polkadot-native stablecoin AMM on Astar Network. Its mission is to provide a stable, highly liquid trading platform for stablecoins, deep liquidity for connected protocols, and attract and lock tremendous value to facilitate more innovations and collaborations for Astar and Polkadot. On Sirius Finance, nASTR holders can swap or deposit their tokens to provide liquidity in the nASTR:ASTR stable pair. In return, they will receive LP tokens and can stake them on Sirius to earn extra trading fees and rewards in Sirius's farming pool. ### How to farm nASTR/ASTR on Sirius Finance Once you have staked ASTR tokens on algem.io and received nASTR tokens, select Sirius Finance in the nASTR farming and you can follow this guide. {% content-ref url="/pages/dXjOl0eSL8bkJJIQId00" %} [How to use Algem's nASTR Farming](/get-started/how-to-use-algems-nastr-farming) {% endcontent-ref %} ### Sirius Finance's particularity: When a user wants to provide liquidity on Sirius Finance, they have the option of providing one or both assets. If a user provides one or both assets but with a different balance than the asset balances in the pool, Sirius will automatically balance the user's liquidity based on the balance of the assets in the pool. *EX: The nASTR-ASTR ratio is 55-45 in the pool, so if someone adds 1000 nASTR to the pool, 450 of their nASTR will automatically be replaced by 450 ASTR. And the balance will be 550 nASTR and 450 ASTR. So the user will receive staking reward based on 550 nASTR.* ### Be aware of risks! Before using a DEX like Sirius Finance, be sure you are aware of the risks: * **Impermanent loss & loss of peg.** The nASTR/ASTR pair can fluctuate and lose its 1:1 peg on Sirius depending on market and user usage (swap, buy and sell). Before using the protocol, we highly recommend reading the code and understanding the risks involved with being a Liquidity Provider(LP)and/or using the AMM to trade pegged value crypto assets. See [Impermanent loss](https://finematics.com/impermanent-loss-explained/) for more. * **Smart-contract risks.** Sirius Finance has been already audited twice but please keep in mind that security audits don’t completely eliminate risks. Do not supply assets that you cannot afford to lose to Sirius Finance as a liquidity provider. ### Smart Contracts:

Algem’s nASTR Farming is now supporting SiO2 Finance. nASTR holders can lend their tokens as collateral to borrow other assets available on the lending platform such as ASTR, DOT, USDT, USDC, WBTC, WETH, etc. ## How to supply your nASTR and borrow on SiO2 Finance Once you have staked ASTR tokens on [algem.io](http://algem.io/) and received nASTR tokens, select SiO2 Finance in the nASTR farming. **⚠️ Warning: Before borrowing other assets on SiO2, be sure to understand** [**the concept of Health Factor, Borrowing limit and liquidation using a lending platform.**](https://docs.algem.io/get-started/how-to-use-algems-nastr-farming/sio2-finance#be-aware-of-risks) **⚠️** From the launch of the adapter, only the ASTR token can be borrowed for the first few weeks, to avoid the risk of liquidation while Algem users familiarize themselves with the concept of the lending platform. ### **nASTR Market Details:** **Loan to Value : 30%** - You can borrow up to 30% of your nASTR Collateral Value; **Liquidation Threshold : 48%** - If the borrowed value rises over 48% of the collateral, the position is collateral deficient. *The liquidation threshold is typically higher than the LTV ratio. For example, if the liquidation threshold for an asset is 48%, and a borrower has borrowed to the maximum LTV of 30%, if the value of their collateral falls such that their loan now represents 48% or more of the value of their collateral, their collateral will be liquidated.* *Example: Suppose a user deposits 10000 ASTR worth $1000 as collateral. With an LTV ratio of 30%, they can borrow up to $300 worth of another asset. If the price of ASTR drops such that the value of their collateral falls to $833.33, their loan now represents 48% of the value of their collateral ($300/$625 = 48%). At this point, the platform will initiate liquidation of the borrower's collateral to repay the loan.* **Liquidation Penalty : 12.50%** *The liquidation penalty is an additional charge that is applied when a borrower's collateral is liquidated. This serves as a deterrent to borrowing more than can be safely repaid, and provides additional security to lenders.* *The liquidation penalty is added to the amount the borrower owes at the time of liquidation. The borrower's collateral is sold off until the loan plus the liquidation penalty is repaid.* *Example: Using the same example, suppose there's a 12.5% liquidation penalty. If the borrower's loan of $300 is being liquidated, an additional $37.5(12.5% of $300) is added to the amount they owe. Their collateral will be sold off until $337.5 is repaid.* ### **How to Supply your liquidity:** * Select the Supply option; * Enter the amount of nASTR you want to supply; * Confirm the action by clicking on “Deposit” and signing the transaction in your wallet.
**Option:** If you have already provided liquidity on SIO2 and received I-tokens, you can still deposit your I-tokens tokens on Algem Farming. ### **How to Borrow assets:** * Click the Borrow option; * Choose the token you want to borrow from the available list; * Enter the amount; * Check your borrowing limit and health factor; * Confirm the action by clicking on “Borrow” and signing the transaction in your wallet.
### **How to Repay your debts:** * Select the Borrow option and switch to Repay; * Choose the token you want to repay from the borrowed list; * Enter the amount you need to repay; *The amount to be repaid is higher than the amount borrowed, as it includes interest on the loan.* * Check your borrowing limit and new health factor; * Confirm the action by clicking on “Repay” and signing the transaction in your wallet.
### **How to Withdraw your liquidity:** * Be sure to have claim all your farming rewards before withdrawing your liquidity; * Select the Supply option and switch to Withdraw; * Enter the amount of nASTR you want to withdraw; * Check to see if your borrowing limit and health factor allow you to withdraw your deposited tokens; *If not, you must first pay off some or all of your debts before you can withdraw your liquidity.* * Confirm the action by clicking on “Withdraw” and signing the transaction in your wallet.
### **How to increase your Health Factor:** If your health factor is close to 1, you risk being liquidated, so it would be wise to increase it. To increase your health factor, you can * Repay your borrowing position; * Supply more collateral (nASTR); ### **Claim your rewards from the nASTR Farming** * Select the SiO2 Fiance dApp in the farming section; * Click on the **“Claim rewards”** button and sign the transaction in your wallet; * Your rewards will be distributed directly into your wallet
## A Defi strategy using Algem and Si02 Finance : This is an example of a Defi strategy using SiO2 on Algem to maximize liquid dApp staking and earn more staking rewards with a set amount of ASTR tokens : * Stake 1000 ASTR on Algem, receive 1000 nASTR; * Lend 1000 nASTR on Si02 on Algem’s Farming; * Borrow up to 500 ASTR; * Stake again 500 ASTR on Algem and receive 500 nASTR; * Collect your staking rewards; From 1000 ASTR, you are now receive staking rewards of 1500 nASTR (1000 ASTR deposited + 500 ASTR borrowed).
## Be aware of risks! Before using a Lending protocol like SiO2 Finance, be sure you are aware of the risks: * **Liquidation:** Similar to all forms of Defi lending, there exists a risk of borrower default in Defi lending. When a user engages in borrowing within a lending platform, their position becomes associated with a "health factor." This health factor (HF) serves as an indicator of the security level of a deposited position compared to the borrowed position. A higher HF signifies a more secure state for the assets deposited, reducing the likelihood of liquidation. In instances where the HF drops below 1, the assets held in deposit may be subjected to liquidation. Liquidation involves a process where a portion of the borrower's debt, up to a specified percentage (X %), is settled. This value, along with the applicable liquidation fee, is deducted from the user's available collateral. Subsequently, the liquidated debt amount is repaid. To prevent liquidation, it is crucial to maintain an HF exceeding 1. To consolidate the Health factor, users have the option of increasing their collateral or partially repaying the loan amount \ See more in [SiO2 Finance’s documentation](https://sio2-finance.gitbook.io/en/systems/risk-parameters). * **Smart-contract risks.** SiO2 Finance is developed based on Aave V2 which is already [heavily audited](https://docs.aave.com/developers/v/2.0/security-and-audits). SiO2 has been also [audited by PeckShield](https://github.com/SiO2-Finance/contracts/tree/main/audits) but please keep in mind that security audits don’t completely eliminate risks. \ Do not supply assets that you cannot afford to lose to SiO2 Finance as a lender. ## Smart-contracts:

# How to transfer nASTR tokens with Algem When staking ASTR tokens in any dApp of Liquid Staking Multipools, you'll earn nASTR tokens, each with its own unique utilities. For instance, Astar Degens or Algem dApp will label nASTR tokens as nASTR-AstarDegens or nASTR-Algem for Algem's smart-contracts. However, to use or trade them on other Astar protocols, they're considered as classic nASTR tokens. When transferring nASTR tokens from a specific dApp, utilize Algem's transfer feature to choose from which dApp among those staked you'd like to transfer nASTR. Otherwise, the tokens will be randomly selected from those in your wallet. ### **To transfer nASTR tokens using Algem, follow these steps:** * Go to the Liquid Staking Dashboard and click on “Send nASTR” button next to your detailed stake; * From one of the available dApps, enter the amount of nASTR tokens you want to transfer; * Note that you can choose different dApps at the same time with different nASTR amounts; * Enter the destination EVM address; * Confirm your action by clicking on the send button.
# Introduction Security ranks supreme in Algem's priorities. We understand security as an ongoing process, constantly refining our defenses to ensure users' comprehensive protection. ### Algem's security roadmap: A global approach Our [Algem Security Roadmap](https://kiwi-professor-a36.notion.site/Algem-Security-Roadmap-52ccab54b5554383ac10fbb601527ee9) embodies our strong position. It describes the key parameters we address to establish comprehensive security. ### Algem contract documentation: Focus on transparency For greater transparency, explore Algem's [Contract Documentation](https://docs.algem.io/development/contracts). It hosts all contracts deployed, highlighting our dedication to openness. In short, Algem is relentless in its pursuit of security excellence, setting industry benchmarks and providing a secure space for all. # Contracts information ## Security deployment and contract administration Algem contracts are deployed using GitHub CI and incorporate OpenZeppelin library modules, bolstering protocol dependability. A majority of these contracts are designed for upgradability. When engaging with such contracts, remember to exclusively employ the Proxy address. ## Role-based smart-contact management Algem employs a role-based system for managing smart contracts. This entails confining vital operations to the multisig wallet, while routine, non-critical actions are permissible via the ordinary wallet. This system encompasses two distinct roles: * **DEFAULT\_ADMIN\_ROLE** 3/4 Gnosis Safe Multisig controlled by the two Algem team members and two Astar Network Core team members. Multisig address: [0xf1893e221227ff7B28D0dBe4dc367F54AAf9BEBD](https://blockscout.com/astar/address/0xf1893e221227ff7B28D0dBe4dc367F54AAf9BEBD) (Astar Network mainnet). All the contracts changes and grant/revoke role operations could be made only under the DEFAULT\_ADMIN\_ROLE (via the multi-signature transaction). * **MANAGER** Regular address with Algem development team access. Manager address: [0xf9B9068276163f47cd5599750496c48BeEba7B44](https://blockscout.com/astar/address/0xf9B9068276163f47cd5599750496c48BeEba7B44) (Astar Network mainnet). This role is used for the non-crucial operations which cannot affect the security level of the dApp such as setting the minimal staking amount, etc. For a comprehensive rundown of operations allocated to each role, please refer to the [Miro board](https://miro.com/app/board/uXjVMPk0_uk=/) provided. ## Deployed Smart Contract Addresses View Algem's Smart Contracts on Github: {% embed url="" %} 1. **Liquid Staking** Contract name: Liquid Staking\ Contract address: [0x70d264472327B67898c919809A9dc4759B6c0f27

Presently, it's activated for the following contracts: * Liquid Staking * NASTR * Sio2 Adapter Pause functionality adheres to the Pausable module standard within the OpenZeppelin library for all these contracts. **Contract.pause()**\ Pause a contract by setting the paused boolean flag to True. **Contract.unpause()**\ Unpause a contract that was previously paused, re-enabling exchanges. **Disabling functionality:** 1. Liquid Staking\ All calls to contract functions are blocked. 2. NASTR * transfer() * transferFrom() * mint() * burn() 3. Sio2 Adapter * supply() * withdraw() * borrow() * addSTokens() * claimRewards() ## Timelock Our contracts operate without a time-lock function, as administrative actions are exclusively managed through the multi-signature wallet's address. This design guarantees swift execution of administrative decisions, eliminating the necessity for time-based delays, all the while upholding a secure and well-regulated environment. ## On-chain threats monitoring system Presently, the Algem team is actively investigating on-chain monitoring systems, akin to the functionality offered by platforms such as [Forta](https://forta.org/). # Internal practices ## Product architecture design workflow Security is rooted in a sturdy product architecture design.

Algem est développé autour de deux fonctionnalités principales proposant différentes solutions aux utilisateurs pour rester liquides avec leurs actifs (ASTR et autres jetons) : — Liquid staking; — Liquid lending. # Liquid dApp Staking {% embed url="" %} Le Liquid Staking est la première et la principale fonctionnalité du protocole Algem qui exploite le dApp staking du réseau Astar. La solution de Liquid Staking d'Algem permet aux utilisateurs de continuer à gagner des récompenses du dApp staking et d'augmenter leurs revenus en utilisant des jetons nASTR liquides et négociables. L'objectif du Liquid Staking est de résoudre des problèmes tels que la liquidité et l'efficacité de l'utilisation des fonds. Les utilisateurs sont constamment confrontés à un choix : staking sur le protocole ou exploiter les agricutures de rendement (farming) sur les dApps, et cette solution permet aux utilisateurs d'obtenir les avantages des deux manières simultanément. Avec la nouvelle version 1.5 du Liquid Staking, Algem adopte davantage la philosophie du dApp Staking en prenant en charge les multipools et en permettant aux utilisateurs de décider sur quel projet ils souhaitent déposer leurs jetons. {% content-ref url="/pages/64KjuuMIgR9FmgQakNKY" %} [ASTR Liquid Staking](/algem-documentation-fr-1/le-protocole-algem/liquid-dapp-staking/astr-liquid-staking) {% endcontent-ref %} {% content-ref url="/pages/3gAAPN1sPMhKR65wkaSG" %} [Unstaking nASTR (récupérer ses ASTR)](/algem-documentation-fr-1/le-protocole-algem/liquid-dapp-staking/unstaking-nastr-recuperer-ses-astr) {% endcontent-ref %} {% content-ref url="/pages/KqmECTXkFtysBawpIR5h" %} [FAQ sur le Liquid Staking](/algem-documentation-fr-1/le-protocole-algem/liquid-dapp-staking/faq-sur-le-liquid-staking) {% endcontent-ref %} # ASTR Liquid Staking Lorsque les utilisateurs déposent leurs jetons ASTR sur la fonction de jalonnement liquide d'Algem, ils reçoivent le même montant en jetons nASTR en retour (ratio 1: 1). ![](/files/RjraL3ADv2on0wGflaIC) Les jetons ASTR déposés sont délégués par les contrats intelligents d'Algem directement au dApp Staking du réseau Astar et commencent à gagner des récompenses de staking. Algem collecte ces récompenses et les distribue, moins une somme modique ([plus d'informations sur nos frais](/algem-documentation-fr-1/le-protocole-algem/revenus-du-protocole)), aux utilisateurs en fonction du solde nASTR dans leurs portefeuilles. Algem suit tous les types de jetons nASTR, incluant les jetons de base, les jetons LP, etc., ce qui signifie que les détenteurs de nASTR peuvent utiliser leurs jetons sur d'autres protocoles defi via le nASTR Liquidity Hub et continuer à gagner des récompenses. Les récompenses de staking sont distribuées selon l'APR et les règles du dApp Staking actuels. De plus, les utilisateurs peuvent réclamer les récompenses sur Algem après chaque nouvelle ère. Avec le dApp Staking Multipools, les détenteurs d'ASTR peuvent choisir la dApp sur laquelle déposer leurs jetons et par conséquant la dApp qu'ils souhaitent supporter à travers le dApp Staking. Lorsqu'un utilisateur décide de déposer ses jetons ASTR sur l'une des dApps disponibles dans le Liquid Staking, les contrats intelligents d'Algem transfèrent directement les jetons ASTR vers le dApp Staking du réseau Astar et les déposent sur la dApp correspondante. De cette façon, Algem conserve et partage la vision du résau Astar afin de créer un écosystème durable où les dApps et les utilisateurs collaborent et se soutiennent mutuellement au profit de l'écosystème. # Unstaking nASTR (récupérer ses ASTR) Pour récupérer leur ASTR, les détenteurs de nASTR doivent retourner leurs jetons à Algem en utilisant l'une des deux options de désengagement disponibles : ### De facon classique L'option de désengagement classique utilise la même fonction que le dApp Staking du réesau Astar. Une fois qu'un utilisateur a retiré ses jetons nASTR, Algem déclenche le retrait sur le dApp Staking d'Astar. Après la fin de la période de désengagement, Algem recevra les jetons ASTR et les distribuera directement dans le portefeuille de l'utilisateur. ### De facon immédiate Avec l'option retrait immédiat, l'utilisateur peut décider de retirer ses nASTR et de recevoir directement ses jetons ASTR sans attendre dix ères, comme dans le cas du retrait classique. En retour, Algem facture une somme modique pour le service. [Plus d'informations sur nos frais.](/algem-documentation-fr-1/le-protocole-algem/revenus-du-protocole) Cette option dépend également de la capacité de la pool de désengagement. La pool contient un certain nombre de jetons ASTR. Le système refusera la transaction si la pool est vide ou n'a pas assez de jetons pour répondre à la demande de retrait de l'utilisateur. Les revenus du protocole alimentent la pool, tout comme le retrait avec option immédiate. C'est-à-dire que si un utilisateur retire immédiatement ses jetons nASTR en utilisant la pool de retrait, il recevra ses jetons ASTR directement de la pool. Pourtant, Algem déclenchera également l'option classique de désengagement dans le dApp Staking. Après dix époques, les jetons ASTR du dApp Staking seront ajoutés et rempliront de nouveau la pool, permettant aux autres utilisateurs de se retirer immédiatement. Le fonctionnement est le même dans les deux options, seuls le temps et les frais changent. Les ASTR reçus après le désengagement ne correspondent pas au montant total du dépôt initial mais au montant des nASTR désengagés. C'est-à-dire que si un utilisateur a acheté ou vendu des jetons nASTR depuis son premier dépôt et a retiré tout son solde de nASTR, il recevra plus ou moins de jetons ASTR que son dépôt initial. ### Q : Quelle est la période de retrait (unstaking)? La période de retrait varie de 10 à 13 ERES (environ 10 à 13 jours). ### Q : Et pourquoi? La période de retrait du dApp Staking sur le résau Astar est de 10 ERES Le dApp Staking a une limite de 4 appels par utilisateur sur une durée de 10 jours. Étant donné que notre contrat de Liquid Staking est considéré comme un unique utilisateur, Algem regroupe tous les appels pour les envoyer au dApp Staking en 4 fois sur 10 jours. C'est pourquoi si vous retirer vos ASTR au début de ce cycle, votre période de retrait sera de 13 ERES. # FAQ sur le Liquid Staking **Q: Qu'est ce le Liquid Staking?** Les membres de la communauté peuvent participer au dApp Staking du résau Astar via notre solution de Liquid Staking. Les utilisateurs recevront des jetons nASTR (une représentation liquide du ASTR déposé), les utiliseront sur Algem ou sur les dApps partenaires, et continueront de recevoir leur récompense de staking. **Q: Comment cela fonctionne?** Lors du dépôt de votre ASTR via le Liquid Staking d'Algem, les utilisateurs reçoivent des jetons nASTR sur une base de 1:1. Les utilisateurs peuvent utiliser leurs nouveaux jetons nASTR dans l'agriculture de rendement (farming), les récompenses de prêt (lending), etc. nASTR conserve un lien 1:1 avec le ASTR. Par conséquent, les dApps peuvent implémenter les mêmes cas d'utilisation pour ce jeton et ainsi augmenter leur liquidité. Le protocole distribue les récompenses de staking en fonction de l'APR et des règles actuelles du dApp Staking. Q : Comment sont comptées les récompenses du dApp Staking? Notre protocole compte les récompenses du dApp Staking en fonction du nombre de nASTR que vous avez et de l'APR actuel. Q : Que se passe-t-il si je vends une partie de mes nASTR ? Vous perdrez la même partie des récompense du dApp staking car vous perdrez les droits sur l'ASTR sous-jacent. Q : Q : Lorsque j'utilise les nASTR pour farmer ou emprunter dans la section nASTR Farming, vais-je continuer à recevoir les récompenses du dApp staking ? Oui. Lorsque vous les utilisez dans le Hub, vous conserver vos droits sur l'ASTR sous-jacent et, par conséquent, sur les récompenses du dApp Staking générées par ces jetons. Q : Combien de temps dure une ère sur le résau Astar? Une ère sur le réseau Astar correspond à 7200 blocs. Le réseau Astar produit un bloc toutes les 12 secondes, donc une ère dure environ 24 heures ou une journée. Consultez la documentation Astar ou le portail pour plus d'informations. Q : Comment réclamer les récompenses du dApp Staking? Connectez-vous sur Algem via MetaMask et réclamez vos récompenses. Q : Quelle est la période de désengagement (unstaking)? La période varie de 10 à 13 ères (environ 10 à 13 jours). Q : Et pourquoi? La période de retrait du dApp Staking sur le résau Astar est de 10 ERES Le dApp Staking a une limite de 4 appels par utilisateur sur une durée de 10 jours. Étant donné que notre contrat de Liquid Staking est considéré comme un unique utilisateur, Algem regroupe tous les appels pour les envoyer au dApp Staking en 4 fois sur 10 jours. C'est pourquoi si vous retirer vos ASTR au début de ce cycle, votre période de retrait sera de 13 ERES. Q : Que se passe-t-il si j'achète des nASTR sur un DEX ou si j'envoie des jetons nASTR à mon autre portefeuille ? Votre adresse, sur laquelle vous détenez des jetons nASTR, commencera à recevoir les récompenses du dApp Staking. En outre, vous pouvez réclamer les ASTR sous-jacent à tout moment sur Algem. Q : Quand puis-je récupérer mes ASTR ? À tout moment via le module de désengagement. À ce moment, le protocole brûlera vos jetons nASTR. Q : Est-ce que nASTR est suffisamment backé par ASTR ? Oui. Les jetons nASTR sont créés sur la base 1-1 au moment du dépôt et sont brûlés au moment du retrait. L'approvisionnement nASTR est contrôlé par le contrat intelligent nDistributor et le seul moyen de créer un nouveau nASTR est de déposer un ASTR via le formulaire de Liquid Staking sur l'application Algem. # Liquid Lending {% embed url="" %} Le Liquid Lending est la deuxième fonctionalité et la plus importante d'Algem, offrant un nouveau concept et un nouveau service à l'ensemble de l'industrie de la defi. La solution de Liquid Lending d'Algem permet aux utilisateurs de continuer à recevoir des récompenses de prêt ou de farming et d'augmenter leurs revenus grâce aux incitations en ALGM tout en utilisant des jetons nASTR liquides et échangeables. Le Liquid Lending utilise les mêmes mécanismes que le Liquid Staking, mais au lieu d'interagir uniquement avec le dApp Staking d'Astar, il est directement connecté aux protocoles des autres dApp du réseau Astar. Les utilisateurs peuvent fournir et prêter leurs jetons aux différents protocoles décentralisés via Algem et en échange recevoir des jetons nASTR liquides représentant leur position de prêt. Grâce à Algem, les détenteurs d'ASTR peuvent fournir ou prêter leurs jetons à des plateformes de prêt ou de staking, à des projets de stablecoin, à des échanges décentralisés ou à d'autres protocoles defi. ![](/files/hc9AKImuEnomoBR84cT2) Le Liquid Lending d'Algem est développé autour de 3 coffres-forts avec des durées différentes (100/200/300 jours) et des incitations en jeton ALGM La durée correspond à l'intention de l'utilisateur de conserver ses jetons et donc de soutenir le protocole. Contrairement au Liquid Staking, où les utilisateurs recoivent immédiatement 100% des jetons nASTR, dans les coffres-forts, une partie des jetons nASTR a une période d'acquisition progressive. Les coffres-forts avec une durée plus longue reçoivent plus d'incitations en ALGM mais en échange ont une plus grande quantité de jetons nASTR vérouillés et une période d'acquisition plus longue. Il ne s'agit pas d'un blocage ferme mais simplement d'une représentation du nombre de jours où les utilisateurs recevront des incitations en ALGM et leurs jetons nASTR. Dans les régles du protocole, les utilisateurs peuvent déverrouiller les jetons à tout moment. *Par exemple, si un utilisateur dépose 1000 ASTR dans le coffre-fort de 100 jours, il recevra immédiatement 930 nASTR (le coefficient de déverrouillage pour le coffre-fort de 100 jours est de 0,93. 0,93 × 1000 = 930), et 70 nASTR sont déverrouillés de manière linéaire. Les jetons non acquis doivent être réclamés manuellement.* Jusqu'à ce que la solution du Liquid Lending soit lancée, les coefficients d'acquisition des nASTR peuvent être adaptés, par coffre-fort, dans l'utilité du protocole. Pour la première itération du Liquid Lending prenant en charge les jetons ASTR, Algem a alloué 15 % de l'offre ALGM (15 000 000 ALGM) comme incitations pour les 3 coffres. Après avoir déposé des jetons ASTR dans l'un des coffres, les utilisateurs choisiront la dApp qui recevra le jeton ASTR et gagneront des récompenses en ALGM. Algem déléguera le jeton déposé à la dApp souhaitée via les contrats intélligents (smart contracts). Ensuite, après un certain temps, Algem, pour avoir apporté de la liquidité, récoltera les récompenses auprès de la dApp. Nous les appelons : Récompenses partenaires. Les récompenses des partenaires sont distribuées aux fournisseurs de jetons ASTR en fonction de leurs parts dans les coffres et de leur pouvoir de vote ALGM. Le pouvoir de vote correspond à la quantité de jetons ALGM qui a été staké sur la pool de la dApp dédiée. Au fil du temps, l'utilisateur recevra du coffre-fort des récompenses en ALGM et pourra les réinvestir dans la pool afin de gagner encore plus de récompenses partenaires. # nASTR Farming Le nASTR Farming - que nous appelions auparavant nASTR liquidiy hub - est un groupe de contrats intermédiaires qui améliorent l'expérience utilisateur en permettant aux détenteurs de nASTR d'interagir avec d'autres protocoles pour utiliser leurs jetons nASTR directement sur Algem.
Les contrats de farming nASTR reçoient des jetons $nASTR, puis transmet les actions au protocole sélectionné. Une fois bloqué dans le contrat, le solde ne peut plus être modifié à moins de retirer la liquidité. Les utilisateurs peuvent transférer des jetons nASTR dans le contrat de farming en une seule transaction, améliorant ainsi l'expérience utilisateur en restant sur le même site Web pour utiliser différents protocoles Defi. En utilisant le nASTR farming directement sur Algem, les détenteurs de nASTR peuvent : * Fournir de la liquidité en nASTR et déposer les jetons LP sur les protocoles AMM standard ou ceux spécialisés dans les stables. * Prêter des jetons nASTR aux plateformes de prêt et les déposer en collatéral. * Réclamer et recevoir les récompenses de farming ### Quel est l'avantage du nASTR Farming? * Protection contre les Flashloan en utilisant un tampon dans l'implémentation: plusieurs scénarios improbables existent lorsque les récompenses de staking peuvent être augmentées rétroactivement via les jetons LP. Par exemple, un utilisateur peut utiliser un prêt flash (flash loan) pour emprunter les jetons avant de réclamer les récompenses et ainsi en recevoir beaucoup plus, tout en retournant les jetons LP à la fin de la transaction. Ce risque augmentera à l'avenir lorsque davantage de dApps Defi proposeront des services de flash loan. * Protection contre les manipulations de LP : certains bots pourraient surveiller le mempool et changer les jetons entre leurs comptes dans le but d'augmenter artificiellement le montant de leur récompense. * Amélioration de l'expérience utilisateur telle que : * Les utilisateurs n'ont plus besoin de visiter plusieurs sites Web pour ajouter leurs jetons aux dApps supplémentaires ; * L'ensemble du processus de dépôt et de retrait des jetons nécessite moins d'actions de la part de lutilisateur; * Les utilisateurs peuvent lire tous les soldes en un seul endroit ; * A l'avenir, les utilisateurs pourront choisir le DEX avec lequel ils souhaiteront interagir et consulter directement les statistiques via Algem. * Au niveau du calcul : Les récompenses sont calculées plus précisémemnt et la sécurité est accrue pour les utilisateurs. * Sécurité : Protection contre la possibilité de drainer des fonds ou de mettre en faillite le contrat de fournisseur LP. * D'avantage de protocoles peuvent être pris en chages: Toutes les dApps ne peuvent pas prendre en charge le $nASTR pour des raisons techniques. Parmi celles-ci figurent des dApps telles que AstridDAO et Arthswap, importantes pour l'écosystème Astar.

Les fonctionnalités de Liquid Staking et de Liquid Lending permettent aux utilisateurs de gagner un revenu supplémentaire. Il s'agit d'une représentation liquide des jetons ASTR au même prix (1:1). Chaque fois qu'un utilisateur dépose ou stake ses ASTR via nos solutions de Liquid Staking ou de Liquid Lending, notre protocole émet un nombre égal de jetons nASTR. Ces jetons représentent la part de l'utilisateur et ses droits de récupérer les jetons sous-jacents. Les utilisateurs peuvent utiliser leurs nASTR dans la section de nASTR farming d'Algem sur les dApps partenaires (pour le staking, le prêt/emprunt, la LP, etc.) ### Ratio ASTR:nASTR Le ratio ASTR:nASTR sur les DEX vise à rester égale, mais le marché peut en décider autrement. Cependant, pour maintenir le ratio aussi proche que possible de 1:1, les détenteurs de nASTR ou d'ASTR peuvent profiter des opportunités d'arbitrage et gagner plus de revenus tout en maintenant la paire stable. Si le ratio ASTR:nASTR diminue en dessous de 1, les tradeurs peuvent vendre leurs jetons nASTR contre des jetons ASTR et les réinvestir sur Algem. Ils se retrouveront avec plus de nASTR qu'au début. Supposons que le ratio ASTR: nASTR passe au dessus de 1, les tradeurs peuvent acheter des jetons nASTR en utilisant des jetons ASTR et les retirer sur Algem en utilisant les options de retrait régulier ou de retrait immédiat. Dans ce cas, ils se retrouveront avec plus d'ASTR qu'au début. ### L'écosystème nASTR Dans nos prochaines itérations, nous nous concentrerons sur le développement de l'infrastructure dans l'utilisation du jeton nASTR à l'intérieur d'Algem. Nous l'appelons le marché nASTR avec ces cas d'utilisation: acheter ou vendre nASTR ; utiliser nASTR comme collatéral. Les utilisateurs peuvent emprunter d'autres tokens s'ils estiment qu'ils peuvent utiliser leur nouveau jeton plus efficacement que le dépôt des nASTR sur une plateforme de prêt ou un AMM. # Rejoindre la communauté Algem Section dédiée à la communauté d'Algem {% content-ref url="/pages/Tuq7SbreqVbIbdzI2CIW" %} [Liens de l'écosystème](/algem-documentation-fr-1/le-protocole-algem/rejoindre-la-communaute-algem/liens-de-lecosysteme) {% endcontent-ref %} {% content-ref url="/pages/lKb5fmh5rzUaUqiA0Ylf" %} [Programme Algyors](/algem-documentation-fr-1/le-protocole-algem/rejoindre-la-communaute-algem/programme-algyors) {% endcontent-ref %} # Liens de l'écosystème **Website:**[ **https://www.algem.io/**](https://www.algem.io/) **Docs:**[ **https://docs.algem.io/**](https://docs.algem.io/) **Github:** [**https://github.com/AlgemDeFi**](https://github.com/AlgemDeFi) **Twitter:**[ **https://twitter.com/Algem\_io**](https://twitter.com/Algem_io) **Telegram:**[ **https://t.me/Algem\_io**](https://t.me/Algem_io) **Discord:** [**https://discord.com/invite/Y7fQNdevV2**](https://discord.com/invite/Y7fQNdevV2) **Blog:** [**https://blog.algem.io/**](https://blog.algem.io/) **Medium:**[ **https://medium.com/@algem**](https://medium.com/@algem) **Media Kit:** [**https://github.com/AlgemDeFi/media-kit**](https://github.com/AlgemDeFi/media-kit)\ \ **DefiLlama:** [**https://defillama.com/protocol/algem**](https://defillama.com/protocol/algem)\ \ **DappRadar:** [**https://dappradar.com/astar/defi/algem**](https://dappradar.com/astar/defi/algem) # Programme Algyors ![](/files/fkJcMbMcePsKLFRw0vcS) ### Bienvenue au programme Algyors ! Les Algyors sont les ambassadeurs d'Algem à travers l'univers de Dotsama, leur mission est de promouvoir notre ville et de contribuer à la croissance et au rayonnement d'Algem. Ils sont également des membres essentiels de notre communauté et de notre ville, aidant nos citoyens et visiteurs lors de leur voyage dans Algem. Les Algyors sont des membres de notre communauté sélectionnés par les Algaris, les fondateurs de la ville. Ils travaillent en étroite collaboration avec les Algaris et font le lien avec la communauté pour améliorer Algem en permanence. ### Consignes 1. La règle la plus importante : soyez toujours poli, peu importe ce que quelqu'un vous écrit. Une approche courtoise l'emporte toujours sur l'impolitesse et les insultes. 2. Soyez aussi précis et concis que possible dans vos réponses. Le temps est une monnaie précieuse, ne perdez ni votre temps, ni celui de l'utilisateur. Si l'utilisateur vous demande un lien, envoyez-lui un lien. Si l'utilisateur vous demande une date de sortie, envoyez-lui une date, etc. 3. N'utilisez pas "bientôt". Bientôt n'existe pas dans le vocabulaire de notre entreprise. 4. Ne répondez pas à la question si vous ne connaissez pas la réponse exacte. Demandez de l'aide à quelqu'un de l'équipe principale. 5. Ne répondez pas à la question si elle a déjà été répondue. 6. Ne vous cachez pas des questions inappropriées. Par exemple, le prix du jeton, la sortie a été reportée, etc. La communication et la transparence sont toujours gagnantes. 99 % de nos utilisateurs sont des gens ordinaires, et les gens ordinaires comprennent que parfois les choses sortent du plan initial. Ils veulent juste savoir pourquoi. 7. N'utilisez jamais de mots comme "mec", "pote", "man", etc. Nous ne sommes pas dans un bar. 8. Encouragez les utilisateurs à laisser des commentaires concernant notre produit. Nos utilisateurs doivent comprendre que leur avis compte et sera récompensé. 9. Identifier les défenseurs de la marque Algem. Dans le web3, les utilisateurs ont tendance à aider sans aucun paiement. Mais notre objectif n'est pas d'utiliser les gens mais de les stimuler pour diffuser des informations (vidéo, tweets) concernant notre plateforme, créer et gérer des communautés locales, etc. Ils doivent savoir que leurs efforts seront récompensés par des ALGM. 10. Vous pouvez rendre muet ou même bannir sans avertissement les utilisateurs qui enfreignent les règles établies par notre communauté. Notre objectif est de maintenir une communication polie et amicale. ### Programme de récompense des ambassadeurs Missions & Critères * Être un membre actif de la communauté * Comprendre et partager la vision et l'objectif d'Algem * Aidez et répondez à la communauté sur nos réseaux sociaux et canaux communautaires (Twitter, Telegram, Discord) * Modérer nos réseaux sociaux (Discord, Twitter) * Traduisez, publiez les informations, le contenu et les articles importants sur les chaînes communautaires. * Promouvoir Algem dans d'autres communautés Polkadot et crypto. **Comment fonctionne le programme?** Le programme se concentre sur trois tâches principales pour les ambassadeurs : 1.

Il joue un rôle central dans le système de récompense et de vote de la plateforme. Conformément aux valeurs du réseau Astar, nous avons décidé de ne faire aucune vente de nos jetons de gouvernance à la communauté. Chez Algem, nous pensons qu'il est préférable de distribuer les ALGM uniquement aux utilisateurs et supporters de notre projet. *Par conséquent, le seul moyen de recevoir des jetons de gouvernance avant d'être listé sur les échanges est de verrouiller ses ASTR ou d'obtenir un airdrop.* # Tokéconomie Nom du jeton: ALGM \ Nombre de décimales: 18 \ Nombre maximal de jetons: 100,000,000 \ Addresse du jeton: TBD ### ALGM - jeton de gouvernance ALGM est le jeton de gouvernance du protocole Algem. Les utilisateurs peuvent avoir des droits et des pouvoirs de vote en détenant et en utilisant le jeton ALGM sur notre plateforme. ### **A**llocation du jeton ALGM | Titre | Pourcentage | Détail | | --------------------------- | ----------- | ---------------------------------------------------------------------------------- | | Incitations | 50% | Sur 6 ans; | | Equipe | 18% | Véroulliés pendant 6 mois à partir du lancement et libération mensuelle sur 3 ans; | | Premiers investisseurs | 15% | Véroulliés pendant 6 mois à partir du lancement et libération mensuelle sur 2 ans; | | Croissance de la communauté | 7% | Marketing, événements, incitations supplémentaires; | | Réserve | 8% | Dépenses imprévues, etc. | | Airdrop | 2% | Participants au Testnet, premiers membres, Algemantis holders, dApp staking. | ### Calendrier de distribution des ALGM ![](/files/HyZH1O86N0I6rEuVnj16) ### **Airdrop d'ALGM** Nous avons alloué 2 % de l'offre d'ALGM pour récompenser nos premiers supporters et utilisateurs pendant la phase initiale d'Algem. Pour obtenir ces récompenses, les utilisateurs doivent participer et aider au développement d'Algem en testant notre produit, en suggérant des améliorations ou en contribuant à notre protocole et à notre communauté. # L'utilité du jeton ALGM ALGM est le jeton de gouvernance du protocole Algem et possède de nombreuses fonctionnalités. Le but de cette section est d'examiner ses fonctions essentielles. Avant de commencer, il convient de mentionner que le seul moyen pour les utilisateurs de recevoir ALGM est de déposer des ASTR ou d'autres jetons dans un coffre-fort. Il n'y a pas de pre-mine ou d'ICO. En d'autres termes, les utilisateurs doivent participer au Liquid Lending pour commencer à gagner des ALGM. De plus, ALGM permet aux utilisateurs de : * Recevoir des incitations supplémentaires en prêtant aux dApps DeFi partenaires d'Algem; * Percevoir une partie des revenus du protocole en stakant les ALGM sur Algem; * Voter et prendre des décisions sur l'avenir d'une dapp (par exemple, ajouter un nouveau coffre-fort) ou de définir certains paramètres tels que les frais, le poids du coffre-fort, etc. ### Fonctions supplémentaires d'ALGM: Le vote #### Voter pour les dApps via le Liquid Staking Les utilisateurs peuvent choisir les dApps du dApp Staking d'Astar sur lesquelles les ASTR seront déposés via la solution de Liquid Staking d'Algem. Voter pour les dApps qui recevront des liquidités via le Liquid Lending Les utilisateurs peuvent choisir les dApps qui recevront des liquidités (jetons ASTR) via notre fonctionnalité Liquid Lending et ainsi partager une partie de leurs récompenses. Voter pour les fonctionnalités et les mises à jour de l'application Voter sur les mises à jour (ajout de nouveau coffre-fort, modification des paramètres et des frais sur les dApp, etc.) # NFT Collections Algem is the first project on Astar network to experiment with NFT collections and Defi services. Owning one or more of our NFTs gives its owner advantages over Algem's Defi products, such as discounts on fees, increased APR, access to private groups and other gifts. Algem currently has three NFT collections: * Algemantis * Liquid Staking Discount * Algem x Archiverse Dojo ## Algemantis NFT Collection
Algemantis is Algem's core NFT collection and represents Algem's Senators, a group of dedicated users who participate in Algem's important decisions and have access to early releases.

This NFT was offered by Algem to reward all the users who completed the campaign #AlgemDojoContest. The DOJO has been fully developed and modeled in 3D with reference to Algem and Astar’s colors. The building takes its archetype from traditional Japanese craftsmanship while adding neo-futuristic elements to generate a new spatial and visual experience. The space offered within the dojo is thought of as being, a practice area, a place where you meditate, repeat exercises and celebrate learning. It will allow you to remember your participation in the Algem event. Along with the #AlgemDojoContest campaign, you perfected your art by completing different quests in order to discover Astar decentralized ecosystem and Algem application. As of now, you have your personal DOJO which will forever bring back memories of this special time of learning and intimate development. It will allow you, in turn, to transmit the knowledge you’ve learned while bringing in new users. *Developed and built by Archiverse ([www.archiverse.art](http://www.archiverse.art))* **NFT contract name:** Algem Dojo\ **NFT contract address:** [0xeBdA851087FF6A75961781987B9f1F7832D9DeB0](https://blockscout.com/astar/token/0xeBdA851087FF6A75961781987B9f1F7832D9DeB0/token-transfers)\ **Supply:** 160 AD Algem x Archiverse Dojo NFT can be traded on the secondary market on Bluez or Tofu NFT : \ # Revenus du protocole Les revenus du protocole Algem proviennent de deux sources différentes : * Les frais. En contrepartie de ses services, Algem facture une somme modique pour ses différentes fonctionnalités : * Frais de gestion sur le Liquid Staking (frais de 10% sur les récompenses de staking) * Fais lors du retrait immédiat des jetons mis en staking (1% du montant retiré). * Frais de gestion sur le Liquid Lending (frais de 10% sur les récompenses de lending) * Frais sur le nASTR Farming (10% de frais sur les récompenses de farming des partenaires) * Récompenses Build2Earn.

Sachez qu'un audit de sécurité ne garantit pas l'infaillibilité totale d'un protocole. Les risques peuvent toujours être présents. Ne misez pas sur Algem des actifs que vous ne pouvez pas vous permettre de perdre.
* Perte du peg nASTR.\ \ Sur le protocole Algem, il y a toujours un ratio 1:1 pour créer (minter) les nASTR et les retourner. Peu importe le ratio de la paire nASTR/ASTR sur le marché. Les utilisateurs peuvent toujours échanger le même montant d'ASTR à partir de jetons nASTR. Cependant, si les détenteurs de nASTR utilisent leurs jetons dans les DEX pour fournir des liquidités, ils sont confrontés à la possibilité d'une perte impermanente et d'un dépeg comme tout farming dans les DEX. \ \ Pour atténuer ce risque, les utilisateurs peuvent effectuer des stratégies d'arbitrage entre les DEX et le protocole Algem en utilisant les fonctions d'échange (swap), stake et unstake. De cette manière, les utilisateurs ont des incitations financières à conserver le peg ASTR/nASTR et à stabiliser l'écosystème. Voir [la section sur le ratio nASTR:ASTR](/algem-documentation-fr-1/le-protocole-algem/dnts).
* Perte impermanente sur DEX\ \ En substance, la perte impermanente est une perte temporaire de fonds survenant lors de la fourniture de liquidités. Elle est très souvent expliquée comme une différence entre la détention d'un actif et la fourniture de liquidités dans cet actif. Une perte impermanente est généralement observée dans les pools de liquidités standard où le le fournisseur de liquidité (LP) doit fournir les deux actifs dans un ratio équivalent; et que l'un des deux actifs est plus volatil que l'autre. Par exemple, dans un pool de liquidité Arthswap ASTR/WETH 50/50.
Si la valeur de WETH augmente, le pool doit s'appuyer sur des arbitreurs qui s'assurent en permanence que le prix de la pool reflète bien le prix réel et ainsi maintenir la même valeur des deux jetons dans la pool. Cela conduit essentiellement à une situation où le profit du jeton qui s'est apprécié en valeur est retiré au fournisseur de liquidités. À ce stade, si le LP décide de retirer ses liquidités, la perte impermanente devient permanente." Voir "[Qu'est-ce qu'une perte impermanente ? DEFI](https://finematics.com/impermanent-loss-explained/) expliqué" de Finematics pour en savoir plus.

To add a token on Metamask, such as nASTR, you can use the feature on Algem dApp or add it manually using the contract address below. **nASTR:** 0xE511ED88575C57767BAfb72BfD10775413E3F2b0 # Ledger EVM **Astar EVM** app is available on Ledger hardware wallet devices. This means that MetaMask users can now sign transactions for EVM accounts on those networks using Ledger Nano S (plus) or Ledger X devices. You can use your Ledger device to secure your ASTR tokens while using them on Algem protocol. ## Requirements: ### A Ledger device ready to use * [Make sure you have set up your Ledger device](https://support.ledger.com/hc/en-us/articles/360000613793?docs=true) * Update your device to latest firmware * [Nano S](https://support.ledger.com/hc/en-us/articles/360002731113?docs=true) * [Nano S Plus](https://support.ledger.com/hc/en-us/articles/4445777839901?docs=true) * [Nano X](https://support.ledger.com/hc/en-us/articles/360013349800?docs=true) * [Download and install Ledger Live app for your OS](https://support.ledger.com/hc/en-us/articles/4404389606417-Download-and-install-Ledger-Live?docs=true) * [Download and install MetaMask for your browser](https://metamask.io/download/) ### Astar network set up on Metamask When you connect Metamask to Algem dApp, Algem will automatically change the Metamask configuration to Astar Network. Still, if you need to add the network manually, you can find the configuration below. 1. Network name: `Astar Network Mainnet` 2. New RPC URL: \ `https://astar.public.blastapi.io/`\ `https://astar-rpc.dwellir.com/`\ `https://astar.api.onfinality.io/public>]` 3. Chain ID: `592` 4. Currency Symbol: `ASTR` 5. Block Explorer URL(Optional): `https://astar.subscan.io/` ### Install Astar EVM app to your Ledger device 1. Open Ledger Live app and navigate to “Manager” 2. Connect your Ledger Device and unlock it 1. If asked, confirm Ledger Manager on your device 3. Search for “Astar EVM” in the app catalog 4. Click install
## **Connecting your Ledger device to MetaMask** 1. In MetaMask menu select “Connect Hardware wallet: 2. On the next screen select “Ledger” and click “Continue 3. Pair and connect your Device when prompted by the browser: 4. Select an account you wish to connect and click “Unlock”
5\. You should now see your account and balance:
## Receiving tokens To receive tokens, copy the address of your connected account by clicking your account name in MetaMask header, and send some tokens to that address from your preferred source. ## Sending tokens 1. Connect your Ledger device and unlock it and open Astar EVM app. 2. In MetaMask click “Send” button and enter the address you wish to send to 3. Enter the amount to send and click “Next”
4\. When your Ledger device screen is showing “Application is ready”, click “Confirm” in MetaMask 5\. Review the transaction on your Ledger device: 1. Check amount 2. Check receiving address 3. Check network 4. Check fees 5. Either approve or reject the transaction 6\. Check the transaction result in MetaMask “Activity” tab. ## **Interacting with smart contracts** In order to interact with smart contracts, you need to enable blind signing in the Astar EVM app on your Ledger device: 1. Open the app 2. Navigate to “Settings” and confirm 3. Confirm the “Blind signing” option, so it turns to “Enabled” 4. Navigate to “Back” and confirm
## Use your Ledger EVM on Algem In our example, we will see how to stake ASTR tokens on Algem with a ledger device. Once you have configured your ledger, enabled smart-contracts and connected it to Metamask, you can connect your EVM ledger using Metamask to Algem dApp. It will work the same way as a normal Metamask wallet but you will need to confirm every action and transaction on your ledger device.
1. Enter the amount of ASTR token you would like to stake (minimum of 100 ASTR); 2. Confirm your action by clicking on the stake button. 3. Sign the transaction in your Metamask-Legder wallet. 4. Confirm the transaction on your ledger device 1. Blind Signing 2. Check amount 3. Check address (smart-contract) 4. Check fees 5. Approve the transaction
Once Algem has delegated your ASTR tokens to Astar dApp Staking, you will receive the same amount as the amount deposited in nASTR tokens and start earning staking rewards directly on your ledger address. You can add the nASTR token to Metamask by adding the following token address or using the dedicated feature in Algem dApp. ***nASTR:*** 0xE511ED88575C57767BAfb72BfD10775413E3F2b0
To use your nASTR tokens in Algem's nASTR Liquidity Hub, please choose one of the different projects available and follow the corresponding guide. The only difference will be to confirm each transaction using your ledger device as explained above. # \* Polkadot{.js} ### Install Polkadot.js Plugin To create a Polkadot.js, install the Browser Plugin available for both [Google Chrome](https://chrome.google.com/webstore/detail/polkadot%7Bjs%7D-extension/mopnmbcafieddcagagdcbnhejhlodfdd?hl=en) (and Chromium-based browsers like Brave) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/polkadot-js-extension/). \ \ After installing the plugin, you should see the orange and white Polkadot{.js} logo in your browser menu bar. ![](/files/61JK0JZRij4xRQJZE6bg) ### Create Polkadot.js Wallet Open the Polkadot{.js} extension and click on the + button - "Create a new account". ![](/files/BCUMZFIv90Q3wQVeKABp) Polkadot{.js} will randomly generate a new seed for you and display it as twelve words. **Save these words in a safe place.** ![](/files/5CBZcD1n707mm60W0NCu) Choose a descriptive name for your wallet and a password. You must enter your password a second time to confirm it. Congratulations, you have just created your first polkadot (native) substrate wallet! # Transfer assets to Astar Network EVM Astar Network uses two different but related networks, **Astar Substrate and Astar EVM**. The Astar portal is a gateway between those networks, and the portal uses ASTR tokens for gas fees. *If you need ASTR tokens to do a transaction, you can claim free ASTR on the Astar Portal or Astar Discord.* {% embed url="" %} **Algem is, at the moment, only deployed on Astar EVM.** Therefore, to use Algem, you must transfer assets such as ASTR tokens to your Astar EVM wallet. To do so, you have five options. 1. Withdraw from a CEX supporting Astar EVM 2. Transfer from Astar substrate to Astar EVM using the Astar portal 3. Use a bridge 4. Cross-chain swap assets 5. Buy ASTR tokens on a DEX. # From a CEX The Astar blockchain is divided into two chains: Substrate (**Native**) and Ethereum compatible (**EVM**). One supports wallets like [**polkadot.js**](https://polkadot.js.org/extension/), [Talisman](https://talisman.xyz/) (native) or [Subwallet](https://subwallet.app/) (native) and the other supports EVM wallets like[ Metamask](https://metamask.io/), [Talisman](https://talisman.xyz/) (EVM) or [Subwallet](https://subwallet.app/) (EVM). The role of the [Astar portal](https://portal.astar.network/#/assets) is to make the **link between these two chains** to transfer tokens, information or instructions. The token of the Astar Network blockchain is the **ASTR**. It is listed on [many exchanges](https://coinmarketcap.com/currencies/astar/markets/) (CEX or DEX). Among the centralized exchanges are **Binance, Kraken, OKX, Huobi, MEXC, Kucoin, and Gate.io**. If you want to send tokens from a centralized exchange (CEX) like Binance or Kraken to an EVM wallet, like Metamask, on the Astar EVM chain, you have two options: * **CEX supports withdrawals to the Astar EVM chain** * **CEX does not support withdrawals to the Astar EVM chain, only to the Astar Native chain.** ***Be careful, when you try a transfer for the first time, always test a first transaction with a small amount before sending all your funds!*** ### Sending ASTR from a CEX to Metamask using the Astar EVM network. At the moment, only 2 CEX support withdrawals directly to the Astar EVM network: **Gate and MEXC**. 1. To make a withdrawal, go to the "withdraw" section of your CEX (Gate or MEXC). 2. Select the ASTR token and choose the **Astar network EVM;** 3. Enter your EVM address where you want to receive your tokens (Metamask); 4. Choose the amount of ASTR you want to withdraw; 5. Confirm the withdrawal; 6. After a certain period of time defined by the CEX, your tokens will arrive directly in your EVM wallet.
### Sending ASTR from a CEX to Metamask that does not support the Astar EVM network. Most of the CEX mentioned above do not support the Astar EVM network, only the Astar Native network. To send tokens to Metamask, you will first have to send them to a native wallet (polkadot.js, Talisman or Subwallet) and then use the Astar Network portal to transfer them to your wallet on the Astar EVM network. 1. To withdraw, go to the "withdraw" section of your CEX; 2. Select the ASTR token and choose the **Astar Network**; 3. Enter your **native address** where you want to receive your tokens (Polkadot.js); 4. Choose the amount of ASTR you want to withdraw; 5. Confirm the withdrawal; 6. After a certain period of time defined by the CEX, your tokens will arrive directly in your native wallet;
7\. Once your tokens are in your native wallet, log in to the [Astar Network portal](https://portal.astar.network/#/assets); 8\. In the "Assets" section, click on the "Transfer" button on the ASTR token line;
9\. A window will open; 10\. Enter your **EVM address** copied from Metmask and choose the amount of ASTR you want to send; 11\. Confirm and sign the transaction in your wallet extension;
12\. After validation of the transaction on the blockchain, your tokens will be in your EVM wallet. More information in the Astar Network documentation: {% embed url="" %} # Using Astar Network Portal If you hold ASTR tokens in your substrate wallets such as Polkadot.js, Talisman, Subwallet, or others, you can transfer your tokens to an EVM wallet through the Astar Network Portal. 1. First, copy your EVM address (Metamask or Talisman) 2. Connect your substrate wallet to Astar Portal and click "transfer." 3. Past your EVM address and enter the amount of ASTR you want to send 4. Confirm the transfer Please visit the official Astar documentation for a completed guide for token transfer between substrate and EVM wallets. {% embed url="" %} # Using Bridges Suppose you hold ASTR tokens or other assets on EVM blockchains such as Ethereum, Binance, Avalanche, Polygon, or others.

# Sirius Finance [Sirius Finance](https://www.sirius.finance/) is a Polkadot-native stablecoin AMM on Astar Network. Its mission is to provide a stable, highly liquid trading platform for stablecoins, deep liquidity for connected protocols, and attract and lock tremendous value to facilitate more innovations and collaborations for Astar and Polkadot. On Sirius Finance, nASTR holders can swap or deposit their tokens to provide liquidity in the nASTR:ASTR stable pair. In return, they will receive LP tokens and can stake them on Sirius to earn extra trading fees and rewards in Sirius's farming pool. ### How to farm nASTR/ASTR on Sirius Finance Once you have staked ASTR tokens on algem.io and received nASTR tokens, select Sirius Finance in the nASTR liquidity hub and you can follow this guide. {% content-ref url="/pages/dXjOl0eSL8bkJJIQId00" %} [Comment utiliser le nASTR Farming d'Algem](/algem-documentation-fr-1/pour-commencer/comment-utiliser-le-nastr-farming-dalgem) {% endcontent-ref %} ### Sirius Finance's particularity: When a user wants to provide liquidity on Sirius Finance, they have the option of providing one or both assets. If a user provides one or both assets but with a different balance than the asset balances in the pool, Sirius will automatically balance the user's liquidity based on the balance of the assets in the pool. *EX: The nASTR-ASTR ratio is 55-45 in the pool, so if someone adds 1000 nASTR to the pool, 450 of their nASTR will automatically be replaced by 450 ASTR. And the balance will be 550 nASTR and 450 ASTR. So the user will receive staking reward based on 550 nASTR.* ### Be aware of risks! Before using a DEX like Sirius Finance, be sure you are aware of the risks: * **Impermanent loss & loss of peg.** The nASTR/ASTR pair can fluctuate and lose its 1:1 peg on Sirius depending on market and user usage (swap, buy and sell).

# Kagla Finance [Kagla Finance](https://kagla.finance/) is a StableSwap protocol for Astar Network and it aims to be the biggest StableSwap in the ecosystem by offering two important benefits to its users: Low Slippage & High Earnings (user can boost up to 2.5x by voting escrow). Kagla already supports several stable pools including: USDT/USDC/DAI, aUSD, BAI, or BUSD. Recently, Kagla has also launched a new stable pool: nASTR & ASTR allowing nASTR holders to provide liquidity, and perform swaps or arbitrage trading. ### How to farm nASTR/ASTR on Kagla Finance Once you have staked ASTR tokens on algem.io and received nASTR tokens, select Kagla Finance in the nASTR liquidity hub and you can follow this guide. {% content-ref url="/pages/dXjOl0eSL8bkJJIQId00" %} [Comment utiliser le nASTR Farming d'Algem](/algem-documentation-fr-1/pour-commencer/comment-utiliser-le-nastr-farming-dalgem) {% endcontent-ref %} ### ### Kagla Finance's particularity: When a user wants to provide liquidity on Kagla Finance, they have the option of providing one or both assets. If a user provides one or both assets but with a different balance than the asset balances in the pool, Kagla will automatically balance the user's liquidity based on the balance of the assets in the pool. *EX: The nASTR-ASTR ratio is 55-45 in the pool, so if someone adds 1000 nASTR to the pool, 450 of their nASTR will automatically be replaced by 450 ASTR. And the balance will be 550 nASTR and 450 ASTR. So the user will receive staking reward based on 550 nASTR.* ### Be aware of risks! Before using a StableSwap like Kagla Finance, be sure you are aware of the risks: * **Impermanent loss & loss of peg.** The nASTR/ASTR pair can fluctuate and lose its 1:1 peg on Kagla depending on market and user usage (swap, buy and sell). Before using the protocol, we highly recommend reading the code and understanding the risks involved with being a Liquidity Provider(LP)and/or using the AMM to trade pegged value crypto assets. See [Impermanent loss](https://finematics.com/impermanent-loss-explained/) for more. * **Smart-contract risks.** Kagla Finance has been already [audited ](https://docs.kagla.finance/development/audit)by Hacken but please keep in mind that security audits don’t completely eliminate risks. Do not supply assets that you cannot afford to lose to Kagla Finance as a liquidity provider. ### Smart Contracts:

# SiO2 Finance [SiO2 Finance](https://www.sio2.finance/) est le hub de prêt multi-VM sur Astar pour Polkadot. Ils visent à devenir la meilleure plateforme de prêt avec une excellente expérience utilisateur, des fonctionnalités faciles à utiliser en un clic et une gouvernance transparente. Algem nASTR Farming prend désormais en charge SiO2 Finance. Les détenteurs de nASTR peuvent prêter leurs jetons en garantie pour emprunter d'autres actifs disponibles sur la plateforme de prêt tels que ASTR, DOT, USDT, USDC, WBTC, WETH, etc. ## Comment déposer votre nASTR et emprunter sur SiO2 Finance Une fois que vous avez déposé des jetons ASTR sur [algem.io](http://algem.io/) et reçu des jetons nASTR, sélectionnez SiO2 Finance dans nASTR Farming. **⚠️ Attention : Avant d'emprunter d'autres actifs sur SiO2,** [**assurez-vous de bien comprendre** **les concepts de Facteur Santé, Limite d'emprunt et liquidation dans une plateforme de prêt**](https://docs.algem.io/v/algem-documentation-fr-1/pour-commencer/comment-utiliser-le-nastr-farming-dalgem/sio2-finance#soyez-conscient-des-risques)**.** **⚠️** Lors du lancement de l'adaptateur, seul le token ASTR pourra être emprunté les premières semaines, pour éviter le risque de liquidation le temps que les utilisateurs d'Algem se familiarisent avec le concept de la plateforme de prêt. ### **Détails du marché nASTR:** **Ratio prêt-valeur (LTV) : 40%** - Vous pouvez emprunter jusqu'à 40% de la valeur de votre garantie nASTR; **Seuil de liquidation :** 48% - Si la valeur empruntée dépasse 48% de la garantie, le collatéral de la positon est insuffisant. *Le seuil de liquidation est généralement supérieur au ratio prêt-valeur (LTV). Par exemple, si le seuil de liquidation d'un actif est de 48 % et qu'un emprunteur a emprunté jusqu'au LTV maximum de 40%, si la valeur de sa garantie chute de telle sorte que son prêt représente désormais 48% ou plus de la valeur de sa garantie, leur collateral sera liquidée.* *Exemple : supposons qu'un utilisateur dépose 10 000 ASTR d'une valeur de $1000 en garantie. Avec un ratio LTV de 40%, ils peuvent emprunter jusqu'à $400 d'un autre actif. Si le prix de l'ASTR baisse de telle sorte que la valeur de leur garantie tombe à 833,33 $, leur prêt représente désormais 48% de la valeur de leur garantie (400$ / 833,33$ = 48%). À ce stade, la plateforme initiera la liquidation du collatéral de l'emprunteur pour rembourser le prêt.* **Pénalité de liquidation : 12,50%** *La pénalité de liquidation est une charge supplémentaire qui est appliquée lorsque la garantie d'un emprunteur est liquidée. Cela a pour effet de dissuader d'emprunter plus que ce qui peut être remboursé en toute sécurité et offre une sécurité supplémentaire aux prêteurs.* *La pénalité de liquidation s'ajoute au montant que l'emprunteur doit au moment de la liquidation. La garantie de l'emprunteur est vendue jusqu'au remboursement du prêt plus la pénalité de liquidation.* *Exemple : en utilisant le même exemple, supposons qu'il y ait une pénalité de liquidation de 12,5%. Si le prêt de 400$ de l'emprunteur est liquidé, un montant supplémentaire de 50$ (12,5% de 400$) est ajouté au montant qu'il doit. Leur collatéral sera vendue jusqu'à ce que 450$ soient remboursés.* ### **Comment fournir vos liquidités :** * Sélectionnez l'option Supply / Fournir; * Entrez la quantité de nASTR que vous souhaitez fournir; * Confirmez l'action en cliquant sur "Deposit / Déposer" et signez la transaction dans votre portefeuille.
**Option:** Si vous avez déjà fourni de la liquidité sur SIO2 et reçu des I-tokens, vous pouvez toujours déposer vos jetons I-tokens sur Algem Farming. ### **Comment emprunter des actifs :** * Cliquez sur l'option Borrow / Emprunter; * Choisissez le jeton que vous souhaitez emprunter dans la liste disponible; * Entrez le montant; * Vérifiez votre limite d'emprunt et votre facteur santé; * Confirmez l'action en cliquant sur "Borrow / Emprunter" et signez la transaction dans votre portefeuille.
### **Comment rembourser vos dettes :** * Sélectionnez l'option Borrow / Emprunter et passez à Repay / Rembourser; * Choisissez le jeton que vous souhaitez rembourser dans la liste des emprunts; * Saisissez le montant que vous devez rembourser; *Le montant à rembourser est supérieur au montant emprunté, car il comprend les intérêts du prêt.* * Vérifiez votre limite d'emprunt et votre nouveau facteur de santé; * Confirmez l'action en cliquant sur "Repay / Repayer" et signez la transaction dans votre portefeuille.
### **Comment retirer vos liquidités :** * Assurez-vous d'avoir réclamé toutes vos récompenses de farming avant de retirer vos liquidités; * Sélectionnez l'option Supply / Fournir et passez à Withdraw / Retrait; * Entrez le montant de nASTR que vous souhaitez retirer; * Vérifiez si votre limite d'emprunt et votre facteur santé vous permettent de retirer vos tokens déposés; *Si ce n'est pas le cas, vous devez d'abord rembourser une partie ou la totalité de vos dettes avant de pouvoir retirer vos liquidités.* * Confirmez l'action en cliquant sur "Withdraw / Retirer" et signez la transaction dans votre portefeuille.
### **Comment augmenter votre facteur de santé :** Si votre facteur de santé est proche de 1, vous risquez d'être liquidé, il serait donc judicieux de l'augmenter. Pour augmenter votre facteur de santé, vous pouvez: * Rembourser votre position emprunteur; * Fournir plus de garanties (nASTR); ### **Réclamez vos récompenses de farming nASTR** * Sélectionnez la dApp SiO2 Finance dans la section farming; * Cliquez sur le bouton **"Claim rewards / Réclamer des récompenses"** et signez la transaction dans votre portefeuille; * Vos récompenses seront distribuées directement dans votre portefeuille.
## Une stratégie Defi en utilisant Algem et Si02 Finance : Ceci est un exemple de stratégie Defi utilisant SiO2 sur Algem pour maximiser le Liquid dApp staking et gagner plus de récompenses de staking avec un nombre défini de tokens ASTR : * Déposez 1000 ASTR sur Algem, recevez 1000 nASTR; * Prêtez 1000 nASTR sur Si02 sur Algem’s Farming; * Empruntez jusqu'à 400 ASTR; * Déposez de nouveau 400 ASTR sur Algem et recevez 400 nASTR ; * Récupérez vos récompenses de staking; À partir de 1000 ASTR, vous recevez désormais des récompenses de staking de 1400 nASTR (1000 ASTR déposés + 400 ASTR empruntés).
## Soyez conscient des risques ! Avant d'utiliser un protocole de prêt comme SiO2 Finance, assurez-vous d'être conscient des risques : * **Liquidation:** Comme tous types de prêts, les prêts Defi comportent le risque de défaillance de l'emprunteur. Lorsqu'un utilisateur emprunte sur une plateforme de prêt, un « facteur de santé » est associé à sa position. Le facteur de santé (HF) est un indicateur de la sécurité d'une position déposée par rapport à une position empruntée. Plus le HF est élevé, plus les actifs déposés sont à l'abri de la liquidation. Si le HF tombe en dessous de 1, les avoirs déposés peuvent être liquidés. Une liquidation est un processus dans lequel jusqu'à X % de la dette d'un emprunteur est remboursée, et cette valeur avec les frais de liquidation sont prélevés sur la garantie disponible de l'utilisateur. Après la liquidation, le montant liquidé de la dette est remboursé. Pour éviter la liquidation, assurez-vous que votre HF est supérieur à 1. Un utilisateur peut augmenter son HF en déposant plus d'actifs en garantie ou en remboursant une partie du prêt. \ Voir plus dans la [documentation de SiO2 Finance](https://sio2-finance.gitbook.io/en/systems/risk-parameters). * **Risques liés aux contrats intelligents.** SiO2 Finance est développé sur la base d'Aave V2 qui est déjà [fortement audité](https://docs.aave.com/developers/v/2.0/security-and-audits). SiO2 a également été [audité par PeckShield](https://github.com/SiO2-Finance/contracts/tree/main/audits), mais gardez à l'esprit que les audits de sécurité n'éliminent pas complètement les risques. Ne fournissez pas d'actifs que vous ne pouvez pas vous permettre de perdre sur SiO2 Finance en tant que prêteur.

# Comment transférer des jetons nASTR avec Algem Lorsque vous déposez des jetons ASTR dans n'importe quel dApp du Liquid dApp Staking, vous gagnerez des jetons nASTR, chacun avec ses informations uniques. Par exemple, les dApps Astar Degens ou Algem étiquetteront les jetons nASTR comme nASTR-AstarDegens ou nASTR-Algem pour les smart contracts d'Algem. Cependant, pour les utiliser ou les échanger sur d'autres protocoles Astar, ils sont considérés comme des jetons nASTR classiques. Lors du transfert de jetons nASTR à partir d'une dApp spécifique, utilisez la fonction de transfert d'Algem pour choisir à partir de quelle dApp vous souhaitez transférer les jetons nASTR. Sinon, les jetons seront choisis au hasard parmi ceux de votre portefeuille. ### Pour transférer des jetons nASTR à l'aide d'Algem, procédez comme suit : * Accédez au tableau de bord du Liquid Staking et cliquez sur le bouton "Envoyer nASTR" à côté de votre mise/stake détaillé ; * À partir de l'une des dApps disponibles, entrez le nombre de jetons nASTR que vous souhaitez transférer ; * Notez que vous pouvez choisir différentes dApps en même temps avec différents montants nASTR ; * Entrez l'adresse EVM de destination ; * Confirmez votre action en cliquant sur le bouton envoyer.

アルジェムは2つの主要な機能を開発しており、ユーザーが自身の資産（$ASTRや他トークン）を流動的に保つための異なるソリューションを提供しています： * リキッドステーキング * リキッドレンディング # 💦リキッドdAppステーキング {% embed url="" %} リキッドステーキングはアスターネットワークのdAppステーキングを活用したアルジェム最初の主要な機能です。 リキッドステーキングを活用することで、dAppステーキングの報酬を獲得しながらリキッドトークンである$nASTRを用いて収益を増やすことができます。 リキッドステーキングの目標は、流動性や資金の利用効率低下の問題を解決することです。 ユーザーはステーキングかイールドファーミングかの選択を迫られことが良くありますが、リキッドトークンでは両方行うことが可能になります。 リキッドステーキングver.1.5では、dAppステーキングの哲学を取り入れマルチプールをサポートしました。これによりユーザーは好みのプロジェクトにdAppステーキングできるようになりました。 {% content-ref url="/pages/64KjuuMIgR9FmgQakNKY" %} [$ASTR リキッドステーキング](/japanzu/algem-protocol/rikiddodappsutkingu/astr-rikiddosutkingu) {% endcontent-ref %} {% content-ref url="/pages/3gAAPN1sPMhKR65wkaSG" %} [アンステーキング $nASTR](/japanzu/algem-protocol/rikiddodappsutkingu/ansutkingu-nastr) {% endcontent-ref %} {% content-ref url="/pages/KqmECTXkFtysBawpIR5h" %} [リキッドステーキング FAQ](/japanzu/algem-protocol/rikiddodappsutkingu/rikiddosutkingu-faq) {% endcontent-ref %} # $ASTR リキッドステーキング リキッドステーキングを使用すると、預入れた$ASTRと同量の$nASTRを受け取ることができます。 ![](/files/RjraL3ADv2on0wGflaIC) 預入れた$ASTRはアルジェムのスマートコントラクトによってdAppステーキングが行われステーキング報酬を獲得し始めます。獲得された報酬は手数料を差し引いた後、ユーザーの$nASTR保有量に基づいて分配されます。（手数料に関し[てはプロジェクト収益](/japanzu/algem-protocol/purojekuto)を参照ください） アルジェムではLPトークンなどを含めDeFiプロジェクトで利用されている$nASTRの追跡も可能です。これにより$nASTRでイールドファーミングを行っている間もステーキング報酬を受け取ることが可能です。 ステーキング報酬は、現在のdAppステーキングAPRとルールに従って分配されます。また、ユーザーは新元号になるたびにAlgemで報酬を請求することができます。 マルチプールを利用することで、ユーザーは応援したいプロジェクトへdAppステーキングできるようになります。プロジェクトを選択しリキッドステーキングを行うと、アルジェムのスマートコントラクトが選択されたプロジェクトへ直接dAppステーキングを行います。 このように、dAppsとユーザーが協力しつつ持続可能なエコシステムを創造するというアスターネットワークのビジョンに沿ったプロダクト開発を行っています。 # アンステーキング $nASTR $ASTRを回収するには、$nASTRを償還する必要があります。償還方法は以下の2つとなります。 ### 通常のアンステーキング dAppsステーキングを終了する際と同様の手続きとなります。ユーザーがリキッドdAppステーキングへアンステーキングを指示すると、アルジェムはdAppステーキングを解除します。アンボンディング期間経過後、アルジェムからユーザーへ$ASTRが返還されます。 ### 即時アンステーキング アンボンディング期間(10era: 約10日)終了を待たずに$ASTRを受け取ることができます。ただし、少額の手数料が発生します（手数料に関し[てはプロジェクト収益](/japanzu/algem-protocol/purojekuto)を参照ください）。 即時アンステーキングの$ASTRはアンステーキングプールより供給されています。その為、ユーザーからの返還要求量がアンステーキングプール内の$ASTR量を上回る場合トランザクションが棄却されます。 "アンステーキングプールへの$ASTRの供給源はi)プロジェクト収益、ii)即時アンステーキング利用者の$ASTRとなります。 ii)については、即時アンステーキングを利用したユーザーへアンステーキングプールより$ASTRが返済されると同時に、同ユーザーのdAppステーキングが解除されます。10era終了後に返済される$ASTRはアンステーキングプールへと供給され、他ユーザーの即時アンステーキングに利用されます。 " "アンステーキング量はユーザーの$nASTR保有量に依存します。 すなわち、リキッドステーキングを利用後に$nASTRを購入した場合はアンステーキング量が増加し、$nASTRを売却した場合はアンステーキング量が減少します。" ### アンボンディング期間とは？ 基本的に10era \~ 13era (約10日～13日）となります。 ### 通常のdAppステーキングよりアンボンディング期間が長くなるのは何故ですか？。 dAppステーキングへのアンステーキングリクエストは10日間で4回という制限があります。このためアルジェムはユーザーからのアンステーキングリクエスト数がある程度溜まった段階でdAppステーキングを実行します。このタイムラグが最長で3日程度になるため、アンボンディング期間が長くなることがあります。 # リキッドステーキング FAQ #### リキッドステーキングとは何ですか？ 通常のステーキングでは、ユーザーの資産がロックされることを意味します。リキッドステーキングを行うと、ステークしたトークンと同等のリキッドトークン（預かり証のようなもの）が発行され、リキッドトークンを他DeFiで運用しながらステーキング報酬を得られるようになります。 #### どのような仕組みですか？ アルジェムを通してdAppステーキングを行うと、預入れた$ASTRと同量の$nASTRが発行されます。 $nASTRは$ASTRと同価値であり、他のDeFiで運用することが可能なためdAppステーキング報酬を受け取りながらイールドファーミングできるようになります。 アルジェムから受け取るステーキング報酬は基本的にdAppステーキングのAPRに依存します。 #### dAppステーキング報酬量はどのように決定されますか？ ユーザーが保有する$nASTRの数量とdAppステーキングのAPRによって決まります。 #### 保有する$nASTRを一部売却するとどうなりますか？ 売却した$nASTRの数量に応じて報酬が減少します。 #### $nASTRをイールドファーミングで利用中でもステーキング報酬は受け取れますか？ 受け取れます。イールドファーミング利用中の$nASTRもステーキング報酬の対象となります。 #### アスターネットワークにおける1eraの期間は？ アスターネットワークの1eraは7200ブロックです。ブロックは12秒毎に生成されるため1eraは約1日となります。 #### dAppsステーキング報酬の受け取り方は？ ウォレットを利用してアルジェムへ接続し、マニュアルでクレームします。 #### アンボンディングの期間は？ 10era - 13era (約10日～13日)です。 #### 通常のdAppステーキングよりアンボンディング期間が長くなるのは何故ですか？ dAppステーキングへのアンステーキングリクエストは10日間で4回という制限があります。このためアルジェムはユーザーからのアンステーキングリクエスト数がある程度溜まった段階でdAppステーキングを実行します。このタイムラグが最長で3日程度になるため、アンボンディング期間が長くなることがあります。 #### $nASTRを購入した場合や他のウォレットへ送金した場合はどうなりますか？ $nASTRを保有しているウォレットへ報酬が発生します。また、$nASTRを償還し$ASTRに戻すことも可能です。 #### $ASTRへ戻す方法は？ アルジェムでアンステーキングを行えば、いつでも$ASTRに戻すことが可能です。返還された$nASTRはバーンされます。 #### $nASTRは十分な量の$ASTRで担保されていますか？ されています。$nASTRは$ASTRのステーキング時に同量発行され、アンステーキング時に全てバーンされます。$nASTRの供給量はnDistributorというスマートコントラクトで管理されており、$ASTRステーキング時以外は発行されません。 # リキッドレンディング {% embed url="" %} リキッドレンディングはアルジェム2つ目のプロダクトであり、DeFiエコシステム全体において非常に革新的なサービスとなります。 リキッドレンディングを利用することで、レンディング報酬を得ながら$nASTRを運用し、加えて$ALGMを獲得することもできるようになります。 基本的な仕組みはリキッドステーキングと同様ですが、dAppsステーキングの代わりにアスターネットワーク上のレンディングプロジェクトを利用します。アルジェムを通してレンディングを行うと、ユーザーはリキッドトークンである$nASTRを受け取ります。 Algemを通じて、ASTR保有者はトークンを貸出・ステークプラットフォーム、stablecoinプロジェクト、分散型取引所、または他のDefiプロトコルに提供または貸出することができます。 ![](/files/hc9AKImuEnomoBR84cT2) リキッドレンディングには3種類のVautls※があり、それぞれ預入期間(100/200/300日)と$ALGMの報酬量に違いがあります。 ※Vautls：金庫などの意味ですが、資産運用を自動で行うサービスと捉えて下さい。 Vautlsはトークンを保有したい期間やどの程度の期間プロジェクトをサポートしたいかによって選択して下さい。リキッドステーキングと異なり、リキッドレンディングにはベスティング期間が設けられています。すなわち、$nASTRを全額受け取る迄一定の期間が必要となります。 長期間のVautlsを選択するとより多くの$ALGMと$nASTRを獲得できますが、ベスティング期間も長くなります。ただし、資金がロックされる訳ではないため、指定のルールに従い資金の引き出しはいつでも可能です。 *例)　1000ASTRを100日のVautlsへ預入 930nASTRを最初に受け取り (100日Vautlsのアンロッキング係数は0.93：初期受取量: 1000ASTR \* 0.93 = 930ASTR) 残りの70ASTRが一定量ずつ解放されていきます（クレームは手動で行います）* $nASTRのベスティング係数はリキッドレンディング開始まで調整中です。 リキッドレンディング第一弾では$ASTRをサポートする予定です。 3種類のVautlsを用意し、インセンティブとして$ALGM総供給量の15%である15,000,000ALGMを配布予定です Vautlsへ$ASTRを預け入れる際は、レンディング先のdAppsを選択する必要があります。 ユーザーが預入れたトークンはアルジェムのスマートコントラクトにより選択されたdAppsで運用されます。運用先で生み出される報酬はアルジェムによって回収され、これらの報酬をパートナー報酬と呼ぶことにします。 パートナー報酬は各Vautlsへ配布され、各ユーザーの割り当てはVautls内でのトークンシェア率と$ALGMによる投票力により決定されます。投票力はユーザーが選択したdAppへステークした$ALGMの数量によって決定します。 ユーザーはVautlsを利用している間$ALGMを受け取り続けます。受け取った$ALGMを更にステーキングすることで投票力を強めより多くのパートナー報酬を受け取ることが可能になります。 # $nASTR ファーミング $nASTRファーミング - （元$nASTR流動性ハブ） - はアルジェムとパートナープロジェクトを繋ぐスマートコントラクトです。この働きにより、$nASTRホルダーはアルジェムのウエブサイトから直接他のDeFiを扱うことができます。
ユーザーが預けたトークンは$nASTRファーミングコントラクトが受取、他のDeFiで運用されます。また、ロックされたトークンはアンステーキングの指示があるまで動かすことはできません。 $nASTRファーミングコントラクトがあることで、１トランザクションで他DeFiを扱えるためUXの大幅な改善に繋がっています。 $nASTRホルダーは$nASTRファーミングを利用し以下の行動をとることができます： * AMMへ$nASTRの流動性提供、LPトークンのステーキング * $nASTRのレンディング * ファーミング報酬のクレームと受取 ### $nASTRファーミングの利点は？ * バッファード実装によるフラッシュローン保護：LPトークンを使ってステーク報酬を遡及的にブーストできる場合、いくつかのあり得ないシナリオが存在します。例えば、ユーザーはフラッシュローンを使ってLPトークンを借入多額の報酬を請求し、取引の終わりにLPトークンを返却する手法が使えます。フラッシュローンサービスを提供するdAppsが増えれば、こういったリスクは高くなっていくでしょう。 * LP操作からの保護：報酬を人為的に増やすためメンプールを監視し、アカウント間でトークンを入れ替えるボットからトランザクションを保護します。 * ユーザーエクスペリエンス（UX）の向上： * 複数ウエブサイトを訪問する必要がなくなる * トークンの入出金に関するアクション数の低下 * 残高の一元管理 * 将来的に、利用したいDEXの統計情報の閲覧を可能にする * 計算：より正確な報酬計算と、より高いプラットフォームの安全性を実現 * セキュリティ：。LP提供コントラクトによる資金流出や破産の危険性からの保護 * より多くのプロジェクトをサポート：技術的な理由により、すべてのdAppsが$nASTRをサポートできるわけではありません。例) アストリッドDAOやアーススワップ $nASTRファーミングのより詳しい使い方については[こちら](/japanzu/get-started/nastr-fminguno)を参照下さい。 # 💧$nASTR ### $nASTRとは 流動性ステーキングデリバティブ(Liquid Staking Derivatives: LSD)です。$nASTRをアスターネットワーク上のDeFiで運用することで、ユーザー資産の流動性を確保します。 $ASTRのリキッドトークンである$nASTRの価値は$ASTRと1:1となり、アルジェムへ$ASTRを預けると同量の$nASTRが発行されます。 そのため、$nASTRは報酬を受け取る権利を有する債権のようなものです。 $nASTRホルダーは$nASTRファーミングを利用し他DeFiでステーキング、レンディング、流動性の提供などが行えます。 ### $ASTR：$nASTRの比率 $ASTR：$nASTRペアの比率は常に1:1であることが理想ですが、実際の比率はマーケットの状況で変化します。比率の変動はアービトラージの機会を生み出し、$ASTR：$nASTRペアの変動を抑制します。 $ASTR：$nASTRの比率が１を割る場合は、$nASTRを売却し$ASTRを購入・ステーキングすることで、結果的に$nASTRを増やすことができます。 $ASTR：$nASTRの比率が1を超える場合は、$nASTRを購入しアルジェムから$ASTRをアンステーキングすることで、結果的に$ASTRを増やすことができます。 ### $nASTRエコシステム 今後の開発は、アルジェム内で$nASTRを利用するインフラ整備に集中していきます。$nASTRマーケットと名付け、以下の様な利用方法を予定しています。 売買・コレーター利用・ローンの担保（利息以上の運用益が出そうなら）・スワップ（アルジェム内のAMM） #
