🟢 The simple version
Plain English — no jargon. Start here.
Ether.fi is the largest liquid restaking protocol — users deposit ETH and receive eETH (a liquid receipt token), which is automatically staked on Ethereum and restaked via EigenLayer, earning both standard Ethereum staking yield and additional EigenLayer AVS rewards, while remaining freely transferable and usable in DeFi.
Liquid restaking — staking + restaking in one step
Standard Ethereum staking with Lido gives you stETH — liquid staked ETH. You earn ~4% staking yield but do not get EigenLayer's additional restaking yield. Restaking directly on EigenLayer requires running or delegating to an operator, does not give you a liquid token, and has capital lock-up constraints. Liquid restaking protocols like Ether.fi combine both: deposit ETH, receive a single liquid token (eETH) that earns Ethereum staking yield, EigenLayer AVS rewards, and protocol-specific yield — all automatically, with no validator operation required.
The Ether.fi architecture
Ether.fi operates Ethereum validators on behalf of depositors. Uniquely among liquid restaking protocols, Ether.fi validators use "distributed validator technology" (DVT) — validator duties are split across multiple node operators so no single operator has full control, improving resilience. Deposited ETH is staked on Ethereum, and the resulting staking positions are restaked on EigenLayer across multiple AVSs. The combined yield (Ethereum staking + EigenLayer rewards + Ether.fi points) accrues to eETH holders.
eETH and weETH
eETH is a rebasing token — the balance increases as yield accrues (similar to stETH). weETH (wrapped eETH) is a non-rebasing version — the exchange rate increases instead of the balance (similar to wstETH). weETH is the DeFi-compatible form used as collateral in lending protocols (Aave, Morpho) and on Pendle.
What ETHFI does
ETHFI is the governance token. Total supply: 1 billion ETHFI. A large portion was airdropped to early depositors in March 2024 — one of the largest DeFi airdrops that year.
Is it legal in India?
Yes. ETHFI is a VDA under Indian law. 30% tax and 1% TDS apply. See India regulation.

For when you want to go a little deeper.
The liquid restaking flywheel
Ether.fi created a powerful yield stacking: a user deposits ETH → receives eETH (earning Ethereum staking yield) → wraps to weETH → deposits weETH as collateral on Aave or Pendle → borrows ETH against weETH → deposits more ETH → receives more eETH. Each loop earns additional staking yield while simultaneously accumulating EigenLayer points and Ether.fi loyalty points (which were redeemable for ETHFI governance tokens). This recursive loop drove Ether.fi to accumulate billions in TVL rapidly — as of 2026, Ether.fi is the largest liquid restaking protocol by assets managed.
Ether.fi's eETH and weETH are among the most widely integrated assets in Ethereum DeFi. Aave v3 accepts weETH as collateral. Morpho, Compound, and various other lending protocols support it. Pendle has eETH/weETH pools allowing yield tokenisation on top of liquid restaking. Curve and Balancer have eETH liquidity pools for efficient trading between eETH and ETH. The ETHFI token airdrop (March 2024) was notable for distributing a significant portion to early protocol users — a retroactive reward for the "loyalty points" programme.
DVT — distributed validator technology
Ether.fi's use of DVT (using SSV Network and Obol technology) means validator private keys are never held by a single entity. The validator's key is split into shares using threshold cryptography — multiple independent node operators each hold a share and must collaborate to sign attestations. If one operator goes offline, the others maintain liveness. This prevents single-point-of-failure validator slashing and makes Ether.fi's validator operations more robust than single-operator setups.
Key Ether.fi metrics: total ETH deposited (TVL), weETH DeFi integration breadth, operator DVT adoption, ETHFI governance participation, and the EigenLayer points/AVS rewards flowing to eETH holders. The risks: smart contract risk (multiple nested protocols — Ether.fi + EigenLayer + underlying AVSs), DVT key management risk, and the overall restaking systemic risk.

🟣 The full technical picture
For the technically curious.
The eETH rebasing mechanism
eETH uses a share-based system (identical to Lido's stETH mechanism). Each depositor receives "shares" of the total ETH pool. The eETH balance displayed = shares × (totalPooledETH / totalShares). As Ethereum staking rewards and EigenLayer rewards accrue to the pool, totalPooledETH increases while shares remain constant — every eETH holder's balance increases automatically. The rebasing happens daily, reflecting accumulated yield. weETH converts the rebasing to an exchange-rate mechanism: weETH balance is fixed, but each weETH is redeemable for increasingly more eETH (and therefore ETH) over time.

Risk layers in liquid restaking
Ether.fi stacks multiple risk layers. Ethereum staking risk: standard validator slashing risk for double-signing or prolonged downtime. EigenLayer risk: additional slashing from AVS-specific conditions — if an AVS has a bug in its slashing logic, it could slash eETH holders' stake. Protocol risk: a bug in Ether.fi's smart contracts could affect deposits. DVT risk: a bug in SSV or Obol's key management could cause unexpected validator behaviour. These risks are understood but difficult to fully quantify — the additional yield is compensation for bearing these compounded risks.
Ether.fi's withdrawal mechanism: users can request withdrawal of eETH at any time. Withdrawals are processed in a queue — as ETH becomes available from validator withdrawals (requiring an exit queue on Ethereum's consensus layer), it fills withdrawal requests. For instant withdrawals, Ether.fi maintains a liquidity pool where small withdrawal requests can be instantly fulfilled by swapping eETH for ETH at near parity (paying a small fee). Large withdrawals go through the queue and may take days to weeks depending on validator exit queue depth. The instant withdrawal liquidity pool is funded by LPs earning the withdrawal fee.
