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.
