What is Lido? Definition, how liquid staking works, and its benefits

What is Lido?

Lido is a decentralized liquid staking protocol. It lets you stake assets like ETH or SOL while keeping them liquid — meaning you can still trade or use them in DeFi while earning staking rewards.

Instead of locking assets directly in a network validator, Lido stakes on your behalf through professional node operators. In return, you get a liquid staking token (like stETH or stSOL) that represents your staked amount plus rewards.

How it works

  1. Deposit crypto: You send ETH or another supported asset to Lido's staking contract.
  2. Receive liquid token: Lido issues you a 1:1 representation of your staked asset (e.g., stETH).
  3. Earn rewards: Your underlying asset accrues staking rewards through delegated validators.
  4. Stay liquid: You can use or trade your staked token in DeFi without waiting for unstaking periods.

Why Lido matters in crypto

  • Removes the need to run a validator node yourself.
  • Avoids long lock-up periods in staking protocols.
  • Increases capital efficiency by letting you use staked assets elsewhere.
  • Helps secure PoS networks like Ethereum, Solana, and Polygon.

Lido vs Traditional Staking

FeatureLido Liquid StakingTraditional Staking
LiquidityYes — you get a tradable staked tokenNo — assets are locked until unstake
Validator setupManaged by Lido's node operatorsYou set up and maintain your own node
Minimum stakeNo minimum for most assetsOften high (e.g., 32 ETH for Ethereum)
DeFi integrationHigh — can use staked token as collateralLimited

Common uses and examples

  • Staking ETH through Lido to earn rewards and still participate in DeFi.
  • Using stETH as collateral on lending platforms like Aave.
  • Participating in governance decisions for the Lido DAO.

FAQs

  1. Is Lido centralized?: Lido is governed by the Lido DAO. Validator operators are approved by governance, so it's decentralized, but with controlled access to validators.
  2. Does stETH always equal 1 ETH?: Not necessarily — market prices can vary based on liquidity and demand, but it's redeemable for the underlying ETH.
  3. What fees does Lido charge?: Lido takes a percentage of staking rewards as a service fee, split between node operators and the DAO.
