Go to the Stake page of the Magnet DAO website. Select the "Stake" tab.
Enter the amount of MAG that you would like to stake in the input field. If you would like to stake all your $MAG, press the "Max" button and the input field will be populated with all your available $MAG balance.
Click "Approve" and sign the transaction.
After the "Approve" transaction has been processed successfully, click "Stake" and sign the transaction. Tada, you have staked your $MAG.
Note: The "Approve" transaction is only needed when staking/unstaking for the first time; subsequent staking/unstaking only requires you to perform the "Stake" or "Unstake" transaction.
