ether.fi is the largest liquid restaking protocol — approximately $8B TVL in 2026. Users deposit ETH; ether.fi stakes it via EigenLayer restaking, and issues eETH (a rebasing LRT). What sets ether.fi apart is its non-custodial validator key architecture — users retain their own withdrawal credentials, a genuine security improvement over most restaking alternatives.
What ether.fi actually is
ether.fi is a liquid restaking protocol on Ethereum. Deposit ETH, receive eETH. Behind the scenes, ether.fi stakes your ETH to Ethereum validators AND restakes to EigenLayer AVSs (Actively Validated Services) that share validator security.
eETH is a rebasing token — your balance grows automatically as staking + restaking rewards accrue. weETH is the non-rebasing wrapper preferred by DeFi protocols.
Non-custodial validator keys
Most LRTs (Lido and derivatives) hold validator withdrawal credentials centrally. If the protocol operator goes rogue, they could theoretically move validator funds.
ether.fi's architecture keeps withdrawal credentials in user-controlled DVT (Distributed Validator Technology) setups. Users retain custody of their withdrawal keys, dramatically reducing single-point trust in the protocol operator.
Yield sources
- Base ETH staking: ~3-4% APR
- EigenLayer restaking rewards: variable per AVS, growing as more AVSs launch
- ether.fi points/loyalty rewards: points-based rewards ongoing
- ETHFI token: launched 2024, distributed via airdrops to users
Who should use ether.fi
- ETH holders wanting restaking yield with strongest custody model
- Users wanting deep DeFi integration for eETH/weETH
- Long-term ETH holders seeking layered yield
Verdict
ether.fi is the reference liquid restaking protocol. Non-custodial key architecture + broad DeFi integration + largest TVL make it the default LRT choice.
