ether.fi is a liquid restaking protocol on Ethereum. Their liquid restaking token, eETH, is the first native liquid restaking token on Ethereum. Stakers can mint eETH on ether.fi. When a user does this, ether.fi will then stake and restake the ETH, allowing users to maximize rewards. By minting eETH you are getting exposure to 4 types of rewards: Ethereum staking rewards, ether.fi Loyalty Points, restaking rewards (including EigenLayer points), and the ability to provide liquidity to DeFi protocols.
