EtherFi / eETH

EtherFi is the dominant liquid restaking protocol built on top of EigenLayer. While EigenLayer introduced restaking (re-using staked ETH as collateral for additional services), it launched without native liquid tokens. EtherFi solved this by issuing eETH — a liquid restaking token (LRT) that represents ETH staked through EtherFi and restaked on EigenLayer simultaneously. Users earn: (1) Ethereum base staking rewards (~4% APY), (2) EigenLayer restaking rewards, and (3) EtherFi’s own point/token rewards. Founded by Mike Silagadze in 2022, EtherFi launched in late 2023 and grew to $5B+ in TVL by mid-2024.


What Makes EtherFi Different

The following sections cover this in detail.

Non-Custodial Validator Key Design

Most liquid staking protocols (Lido, Rocket Pool) take custody of users’ ETH to run validators. EtherFi’s innovation:

  • Users deposit ETH → EtherFi pairs with a node operator
  • The user retains their validator withdrawal key (not the node operator)
  • Node operators use a distributed key sharding system — they can operate but cannot withdraw
  • Result: True non-custodial staking — EtherFi can’t rug-pull your balance

This is different from Lido where you fully trust Lido’s smart contracts and validators with your ETH.


eETH and weETH

eETH (EtherFi’s liquid staking token):

  • 1 eETH ≈ 1 ETH (rebasing token — balance automatically grows as rewards accumulate)
  • Represents ETH staked through EtherFi + restaked on EigenLayer
  • Yield: base ETH staking (~4%) + EigenLayer AVS rewards (variable)

weETH (wrapped eETH):

  • Non-rebasing version of eETH (price appreciates vs. ETH rather than balance growing)
  • Used in DeFi (most DeFi protocols can’t handle rebasing tokens)
  • weETH used as collateral in Aave, Morpho, Compound, Spark
  • ERC-4626 vault token: weETH price increases relative to ETH over time as rewards compound

EigenLayer Integration

EtherFi is EigenLayer’s largest liquid restaking partner:

  • All EtherFi ETH is restaked into EigenLayer
  • When EigenLayer AVSes (Actively Validated Services) launch and distribute rewards, eETH holders receive them
  • Point system (pre-token): EtherFi distributed “loyalty points” to eETH holders; EigenLayer distributed “restaking points” — both systems rewarded early restakers ahead of token launches
  • eETH holders received ETHFI airdrop + EIGEN airdrop based on points accumulated

ETHFI Token

EtherFi’s governance and utility token:

  • Airdrop: March 2024; early users received ETHFI based on loyalty points
  • Total supply: 1 billion ETHFI
  • Revenue sharing: ETHFI stakers can receive a share of EtherFi’s protocol revenue (6% of staking rewards)
  • Governance: Controls EtherFi DAO and protocol parameters

Revenue model:

EtherFi takes a 10% fee on staking rewards:

  • 5% to node operators
  • 5% to EtherFi protocol (split between DAO treasury and ETHFI stakers)

Cash Card Product

EtherFi launched Cash — a credit/debit card product allowing eETH holders to:

  • Spend yield while their principal continues staking
  • Pay expenses with a Visa-branded card funded by eETH yield
  • No liquidation of principal required for spending

This “DeFi debit card” product is a narrative differentiator attempting to bridge DeFi yield to real-world spending.


Comparison: EtherFi vs. Lido

Feature EtherFi Lido
Key custody User retains withdrawal key Lido holds keys
EigenLayer restaking Yes (native) Via Symbiotic (separate)
Token ETHFI LDO
TVL (mid-2024) $5B+ $30B+
LRT issuance eETH / weETH wstETH (not an LRT)
Governance decentralization Developing More mature DAO

Liquid Restaking Token Ecosystem

EtherFi is the largest but competes with:

  • Renzo (ezETH): Second-largest LRT; significant growth 2024
  • KelpDAO (rsETH): Third LRT tier
  • Puffer Finance (pufETH): Anti-slashing LRT design
  • Swell (swETH/rswETH): Swell Chain (AltLayer-based L2)
  • Bedrock (uniETH): Smaller but growing

The LRT landscape consolidated quickly — EtherFi’s early lead and ETHFI airdrop gave it a TVL moat.


How to Stake with EtherFi

  1. Visit ether.fi
  2. Connect an EVM wallet (MetaMask, Coinbase Wallet)
  3. Deposit ETH → receive eETH immediately
  4. Optionally: wrap eETH into weETH for DeFi use
  5. Use weETH in Aave, Morpho, or Pendle as collateral or yield-bearing asset

Acquire ETH via . Store multiple tokens including weETH securely with .


Social Media Sentiment

EtherFi is generally well-regarded in the ETH staking community for its non-custodial design principle — retaining user withdrawal keys is a genuine safety innovation over Lido’s model. The ETHFI airdrop was considered fair relative to many 2024 airdrops; early and medium users all received meaningful allocations. Critics note that EigenLayer restaking rewards were initially minimal (most AVSes not yet launched) — so the “extra restaking yield” narrative outpaced actual delivered yield. The Cash card product is seen as innovative for connecting DeFi yield to real-world spending but unproven at scale. The LRT sector broadly faces “points fatigue” criticism — complex multi-protocol reward systems that confused users and drove speculation rather than sustainable usage.
