What it is
Lido lets users stake any amount of ETH and issues stETH, a liquid token representing a share of pooled staked ETH plus accrued rewards.
Technology & consensus
ETH is pooled in the protocol, delegated to the operator set, and stETH rebases daily from the share rate as consensus-layer rewards accrue.
Token utility
stETH is transferable and composable across DeFi while accruing staking rewards, and it is the sole input to the protocol withdrawal queue for redeeming ETH.
Key risks & notes
stETH can trade below its reserve value (depeg risk as seen in 2022), slashing and validator penalties reduce rewards and can trigger bunker-mode withdrawal delays, and operator concentration plus DAO governance upgrades create protocol-level risk.
