Lido Liquid Staking: stETH, wstETH, and DeFi Risks
Summary
The document explains Lido's liquid staking model: users deposit ETH and receive stETH, which represents staked assets while remaining transferable and usable in DeFi. Because stETH is rebasable, balances change as rewards accrue. Wrapped stETH (wstETH) provides a non-rebasing alternative, representing rewards through its exchange rate and improving compatibility with some applications. The text notes trading and collateral use, as well as institutional integrations.
It outlines operational and market considerations, including selected node operators, audits, bug bounties, and a past oracle-key compromise. It also describes falling staking yields as participation rises and raises concerns about concentration, reporting that Lido once held a large share of staked ETH. Ethereum's move to proof of stake and the Shapella withdrawals feature are presented as drivers of liquid staking growth. The account is an overview rather than a risk model: its security and adoption claims are not independently supported here, and the pros and cons sections contain no detail.
Key ideas
- stETH lets users retain a transferable token representing staked ETH and accrued rewards.
- wstETH tracks rewards through its exchange rate instead of changing token balances.
- Liquid staking tokens can be traded or used in DeFi, including as collateral.
- Audits and operator selection are described as safeguards, while a past oracle-key compromise shows that risks remain.
- Lido's scale raises concerns about validator concentration and Ethereum decentralization.
