Lido Official: Liquid Staking, CSM & stETH Utility 

Lido Official: Liquid Staking & CSM Hub 

Lido Finance Official is the premier liquid staking protocol for Ethereum, managing the largest share of staked ETH in the ecosystem. This technical documentation serves as the primary resource for utilizing stETH Liquid Staking, joining the permissionless Lido Community Staking Module (CSM), and leveraging wstETH Layer 2 Bridge capabilities. Lido solves the "illiquidity" of traditional staking by tokenizing staked assets. 

Lido Ecosystem: The Staking Standard 

Lido defines the liquid staking vertical through its scale and modular architecture.

stETH: When users deposit ETH, they receive stETH. This is a rebasing token; your balance increases daily in your wallet to reflect rewards.

wstETH: For DeFi compatibility (which often struggles with rebasing tokens), users wrap stETH into wstETH. This token increases in price rather than balance and is the standard for stETH DeFi Collateral on Aave and Maker.

Staking Router: Lido uses a modular architecture. The "Curated Module" handles institutional stake, while the Community Staking Module (CSM) allows permissionless entry for solo stakers who provide a bond (ETH/stETH collateral).

DVT & Node Operators 

The infrastructure of Lido Finance Official focuses on decentralizing the validator set.

Simple DVT: Lido utilizes Lido DVT Integration (with Obol and SSV Network). This splits a validator key into shares managed by different nodes. If one node goes offline, the validator stays up. This drastically reduces slashing risk and improves fault tolerance.

Permissionless Entry: Through the CSM, anyone can Run Lido Validator infrastructure. Operators deposit a "Bond" (e.g., 2-4 ETH) to cover potential slashing penalties, allowing them to mint validators for the protocol without being whitelisted.

Oracles: Lido relies on a set of trusted oracles to report the total pooled ETH and validator balances daily, which triggers the stETH rebase event.

LDO, Dual Governance & Yield 

The reward system balances node operator incentives with staker safety.

Eth Staking APR: The protocol aggregates rewards from the Consensus Layer (issuance) and Execution Layer (MEV/Priority Fees). A 10% fee is deducted (split between Node Operators and the DAO treasury), and the rest is distributed to stETH holders.

LDO Governance Token: LDO holders vote on protocol upgrades, fee parameters, and node operator lists.

Dual Governance: To prevent "Governance Attacks" (where LDO holders might vote to steal funds), stETH holders have a veto right. If the DAO proposes a malicious change, stakers can block execution and trigger a "Rage Quit" to withdraw their ETH safely.

Security, Audits, and Risks 

Lido Finance Official operates with the highest security standards in DeFi due to its massive TVL.

Audits: The codebase has been audited by every major firm (Sigma Prime, ChainSecurity, Oxorio, MixBytes, etc.). The CSM and DVT modules underwent specific, rigorous reviews before mainnet launch.

Slashing Risk: If Lido validators are slashed (penalized by Ethereum), the loss is socialized across all stETH holders. However, the Lido Community Staking Module uses operator bonds to isolate slashing risks to the specific operator responsible.

Smart Contract Risk: Given the complexity of the Staking Router and withdrawals logic, there is always a residual risk of bugs. Lido maintains one of the largest Bug Bounties in the industry (via Immunefi).

Frequently Asked Questions 

What is the difference between stETH and wstETH? stETH changes balance daily (rebases). wstETH does not change balance; instead, its price increases relative to ETH. Use wstETH for DEXs and Lending apps.

How does the Community Staking Module (CSM) work? The Lido Community Staking Module allows anyone to run a validator by posting a bond (collateral). This makes Lido permissionless and allows home stakers to earn extra commission.

Is Lido safe? Lido is the most battle-tested staking protocol, but it carries smart contract and slashing risks. The Dual Governance model adds a layer of protection for stakers against governance attacks.

Can I use stETH on Layer 2? Yes, you should bridge wstETH to networks like Arbitrum, Optimism, or Base to use it in L2 DeFi applications.
