Lido

Lido has established itself as the dominant liquid staking protocol, particularly for Ethereum. The core value proposition is compelling: stake your ETH and receive stETH, which accrues staking rewards while remaining usable across DeFi. The integration ecosystem is extensive—stETH is accepted as collateral on Aave, Curve, and dozens of other protocols, making it arguably the most composable staking derivative available. However, Lido's dominance raises legitimate centralization concerns. At times controlling over 30% of all staked ETH, it concentrates significant influence over Ethereum's validator set, which runs counter to the network's decentralization ethos. The protocol has taken steps toward decentralization through its DAO and expanding its node operator set, but progress has been gradual. The ~10% fee on staking rewards is standard but worth noting. Smart contract risk, while mitigated by extensive audits, always exists. For most users wanting liquid staking with maximum DeFi utility, Lido remains the default choice—but that market dominance itself is the protocol's most significant drawback.
