Lido is a decentralized liquid staking protocol for Ethereum and other proof-of-stake blockchains. Users deposit ETH and receive stETH in return, earning staking rewards while retaining liquidity for use across DeFi. Governed by the Lido DAO, it is the largest liquid staking protocol by total value locked and a critical piece of Ethereum's staking ecosystem.

Lido controls roughly 25-30% of all staked ETH, making it the dominant liquid staking provider. This concentration has been a point of ongoing debate in the Ethereum community around decentralization.
