What is Lido Finance?
Lido Finance is the largest liquid staking protocol in DeFi. Launched in December 2020, it lets Ethereum holders earn staking rewards without locking up 32 ETH or running a validator node. Users deposit any amount of ETH and receive stETH — a liquid receipt token that accrues staking yield daily and can be used across the broader DeFi ecosystem while the underlying ETH keeps earning.
Lido pools deposited ETH across a curated set of professional node operators who run validators on the Ethereum Beacon Chain. The protocol takes a 10% fee on staking rewards, split between node operators and the Lido DAO treasury. Because stETH rebases daily, holders see their balance increase in their wallets without doing anything.
Security and smart-contract risk
Lido is audited by multiple firms including Sigma Prime, MixBytes, and ConsenSys Diligence. The core contracts have never been exploited, but they represent one of the largest smart-contract attack surfaces in DeFi — over $30 billion in total value locked at peak. The main risk is a slashing event on one of the node operators, which would reduce stETH balances proportionally. Lido holds a slashing insurance fund to partially cover such events.
Node operator concentration is a known governance concern. Around 30 vetted operators run the validators, and critics argue this is less decentralized than solo staking. The Lido DAO is working on the Distributed Validator Technology (DVT) integration via Obol and SSV Network to spread operator risk further.

Yield and tokenomics
stETH yield tracks the Ethereum network base APR, which as of early 2026 sits near 3.5 to 4.5%. The exact rate depends on total ETH staked network-wide, validator queue length, and MEV income. Lido also distributes LDO governance tokens as additional incentive for liquidity providers in certain venues. stETH is the most liquid staked-ETH token, with deep pools on Curve and accepted as collateral on Aave and MakerDAO.
Stakers who want to exit convert stETH back to ETH either through the Lido withdrawal queue (which can take hours to days depending on the unstaking queue on Ethereum) or by selling stETH on a DEX at near-par value. The peg between stETH and ETH has been very stable outside of the June 2022 credit crisis episode, when it temporarily fell to 0.94.
How to stake ETH with Lido
The process takes under two minutes. Connect a Web3 wallet (MetaMask, Ledger, WalletConnect) to stake.lido.fi, enter the amount of ETH to stake, and confirm the transaction. The stETH arrives in your wallet at the end of that block. From there you can hold it, supply it as collateral on Aave, or provide liquidity on Curve or Uniswap.
- Visit stake.lido.fi and connect your wallet
- Enter the ETH amount (minimum 0.01 ETH)
- Confirm the transaction in your wallet
- Receive stETH — balance increases daily automatically
- Optional: deploy stETH in DeFi for additional yield
Who should use Lido?
Lido suits DeFi-native users who want to keep their staked ETH productive across lending, liquidity provision, or as collateral — situations where locked solo-staking or even a centralized exchange staking product would not work. The trade-off is smart-contract exposure and partial reliance on a DAO governance system. If you want maximum simplicity and do not use DeFi, Coinbase Earn or Kraken Staking are easier. If you are running a node anyway, Rocket Pool gives better decentralization without sacrificing much yield.
stETH is accepted as collateral by Aave, Compound, and MakerDAO — making it one of the most composable yield-bearing assets in DeFi.
