Swell is a non-custodial liquid staking protocol.
Swell allows users to earn ETH staking rewards without locking ETH or maintaining staking infrastructure. Users deposit their ETH into Swell's smart contracts and receive swETH or rswETH (restaked ETH in EigenLayer) in return that represent the value of the user's staked assets along with any staking rewards accrued or penalties inflicted on validators.
Swell generates revenue by charging a 10% fee on the staking rewards earned by ETH depositors. This fee is split evenly between node operators and the Swell DAO treasury. There are currently no fees for Swell's restaking product.
You can generate additional yield on top of your ETH by depositing into Swell to participate in the Ethereum PoS validation mechanism to earn block rewards. The unlocked liquidity with swETH can also be redeployed within several popular DeFi protocols to generate additional yield on top of the staking rewards. Alternatively, you can mint restaked ETH (rswETH) to earn restaked rewards through EigenLayer.
