🟢 The simple version
Plain English — no jargon. Start here.
ether.fi is the largest liquid restaking protocol by TVL — you deposit ETH, receive weETH (wrapped eETH) that earns both Ethereum staking rewards and EigenLayer restaking rewards simultaneously, with a key differentiator: you retain ownership of your validator keys rather than handing them to a third party.
What makes ether.fi different from Lido?
Lido (stETH) is the dominant liquid staking protocol — deposit ETH, get stETH, earn Ethereum staking rewards. Simple. But Lido holds your validator keys: Lido's node operators control the actual validators. If you want to unstake, you go through Lido's queue. ether.fi's model: when you stake ETH, a validator is created with keys that only you hold. You delegate staking to an ether.fi operator, but you can exit the validator yourself at any time without permission from ether.fi. This is "non-custodial liquid staking" — a meaningful distinction given the growing debate around Lido's centralisation of Ethereum staking.
On top of this, ether.fi automatically restakes your ETH via EigenLayer, so weETH earns staking rewards + restaking rewards from EigenLayer AVSes in a single token.
eETH and weETH
When you deposit ETH into ether.fi, you receive eETH — a rebasing token (balance increases as rewards accrue, like stETH). weETH is the wrapped version (non-rebasing — price appreciates instead of balance increasing), which is more compatible with DeFi protocols. Both represent the same underlying position. weETH has become one of the most widely integrated LRT tokens across DeFi lending markets.
ETHFI token
ETHFI is the governance token of ether.fi. Total supply: 1 billion. ETHFI launched in March 2024 via a large airdrop to early depositors and loyalty points participants. ETHFI token holders govern protocol parameters including AVS selection (which EigenLayer services ether.fi restakes to) and fee settings.
Is ETHFI legal in India?
Yes. ETHFI qualifies as a Virtual Digital Asset (VDA) under Indian law. 30% tax on gains and 1% TDS applies. weETH yield accumulation is also taxable income. Consult a tax professional.

ether.fi's scale — why it matters
By early 2025, ether.fi had grown to become the largest liquid restaking protocol, surpassing competitors like Renzo and Puffer in TVL. This scale matters for DeFi integration: the more weETH exists, the more DeFi protocols integrate it as collateral, which creates more demand for weETH, which brings more depositors. Aave, Morpho, and other major lending platforms accept weETH as collateral, making it functionally similar to stETH in utility — but with the additional restaking yield layer.
Cash (CASH) — ether.fi's DeFi expansion
ether.fi launched "Cash" — a DeFi-native credit card product where users can spend their weETH yield without selling their underlying ETH. The card lets users borrow against weETH to fund spending, with the restaking yield partially covering the borrowing cost. This is a novel DeFi-to-real-world product attempting to make restaking yield practically spendable.
ether.fi's non-custodial claim is real but nuanced — the validator key ownership technically belongs to you but in practice most users delegate all operations to ether.fi operators. The added complexity of non-custodial mechanics doesn't eliminate operator risk. EigenLayer slashing adds on top. Bigger TVL = bigger target if a vulnerability exists. Live data: CoinGecko

Non-custodial validator architecture
Standard liquid staking (Lido, Rocket Pool): the protocol generates and manages validator keys. ether.fi: when a new validator is spun up, a distributed key generation (DKG) ceremony creates withdrawal credentials owned by the depositor. The node operator receives signing keys only — they can propose and attest blocks, but cannot withdraw. Only the depositor (or ether.fi's withdrawal smart contract, controlled by the depositor's NFT representing their validator) can initiate withdrawal. This NFT-based validator ownership is ether.fi's core architectural innovation.
