# 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/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
