Everstake said in a post on X that it has become one of the Swell node operators and supports rswETH Liquid Restaking. According to its introduction, Swell is a non-custodial staking protocol that allows users to access the blockchain and AVS rewards for re-staking, while participating in the broader DeFi ecosystem for additional benefits. Its liquidity staking token, rswETH, provides liquidity for ETH re-staking without requiring users to lock in their re-staking ETH.
