Yes, you can use Sei to earn passive income or rewards through staking or other consensus mechanisms using Compass Wallet. Staking is a process where a user locks up their tokens as collateral in order to help secure the network and validate transactions. In return, they receive rewards in the form of more tokens.

With Compass Wallet, you can easily participate in the staking process by delegating your tokens to validators. This can be done through the in-wallet staking feature, where you can view current delegations, stake/unstake/restake and earn rewards.

It's important to note that the amount of rewards you can earn through staking or other consensus mechanisms can vary depending on the current state of the network and the number of tokens you have staked.
