Lido is the largest liquid staking protocol in DeFi, allowing users to stake ETH and receive stETH — a liquid receipt token that represents their staked ETH plus accumulated rewards. As of 2026, Lido controls approximately 28-30% of all staked ETH, making it one of the most systemically important protocols in the Ethereum ecosystem. stETH has become the most widely integrated DeFi collateral after ETH and USDC.
The core innovation of liquid staking is solving a fundamental problem: when you stake ETH natively, it's locked and cannot be used in DeFi. Lido's stETH allows you to earn staking rewards (~3-4% APY) while simultaneously using stETH as collateral in Aave, lending on Curve, or providing liquidity across dozens of DeFi protocols. This capital efficiency effectively doubles the utility of staked ETH.
Lido has expanded beyond Ethereum to offer liquid staking on Polygon, and the protocol generates significant fee revenue — taking a 10% cut of all staking rewards, split between node operators and the Lido treasury.
Lido launched in December 2020, just after Ethereum's Beacon Chain went live. It quickly grew to become the dominant liquid staking provider. stETH's integration across major DeFi protocols (Aave, Curve, MakerDAO) created a flywheel of adoption. The stETH depeg scare in June 2022 (when stETH traded at ~0.95 ETH during the Terra/3AC crisis) tested the protocol's resilience. Lido V2 launched in 2023 with a staking router for distributed validator selection and ETH withdrawals.
Users deposit ETH into Lido's smart contracts and receive stETH at a 1:1 ratio. Lido distributes the deposited ETH among a curated set of professional node operators who run validators on Ethereum's Beacon Chain. Staking rewards are reflected in stETH's balance — stETH is a rebasing token, meaning the amount in your wallet increases daily as rewards accrue. Lido takes a 10% fee on rewards: 5% to node operators and 5% to the Lido DAO treasury. Users can withdraw stETH back to ETH through Lido's withdrawal mechanism or trade it on DEXs.
LDO is the governance token of Lido DAO, with a total supply of 1 billion tokens. LDO holders govern node operator selection, fee parameters, and protocol upgrades. Unlike stETH (which earns yield), LDO itself does not capture protocol revenue — it's a pure governance token. This has been a persistent criticism. The Lido treasury, funded by the 5% fee share, holds significant assets governed by LDO holders.
~30% of all staked ETH flows through Lido — creating massive network effects and deep DeFi integration.
stETH is accepted as collateral on Aave, Maker, and dozens of protocols — maximizing capital efficiency.
Operating since December 2020 with no slashing incidents or smart contract exploits — battle-tested at scale.
10% of all staking rewards generates significant, sustainable revenue for the protocol.
~30% of staked ETH through one protocol raises systemic risk concerns for Ethereum's decentralization.
LDO is a governance-only token — it doesn't capture protocol fees directly, limiting its investment thesis.
Dominant liquid staking could attract regulatory attention as securities or unregistered investment products.
In extreme market stress, stETH can trade below ETH parity, causing cascading liquidations in DeFi.
Liquid staking allows you to stake ETH and receive a liquid token (stETH) that represents your staked position. Unlike regular staking where your ETH is locked, stETH can be traded, used as DeFi collateral, or sold at any time. You earn staking rewards while maintaining liquidity.
This is a legitimate concern. Lido controls approximately 28-30% of all staked ETH, making it a significant concentration point. The Lido DAO governs the protocol and selects node operators. While individual node operators are diverse, the smart contract layer and governance represent centralization risk for the Ethereum network.
LDO's value is tied to Lido's dominance in liquid staking and the growth of staked ETH. Revenue comes from a 10% fee on staking rewards (split between node operators and the DAO treasury). Risks include regulatory scrutiny of liquid staking, competition from Rocket Pool and institutional staking products, and potential Ethereum governance changes that limit any single staking provider's share.
