Liquid staking has fundamentally transformed how users interact with proof-of-stake (PoS) blockchain networks, particularly Ethereum. By allowing token holders to stake their assets while maintaining liquidity, this innovative mechanism has unlocked new avenues for yield generation and DeFi participation. Among the key players in this domain, Lido Finance has emerged as a dominant force, though its market position raises important questions about decentralization and network health.
This article delves into the current state of liquid staking on Ethereum, with a specific focus on Lido's protocol, its staking derivative (stETH), and the ongoing discussions surrounding its influence within the ecosystem.
The State of Ethereum PoS Staking
Ethereum's transition to proof-of-stake consensus, finalized through The Merge and subsequent Shapella upgrade, established a new economic foundation for the network. This shift has led to significant capital allocation toward securing the blockchain through staking.
Currently, approximately 23% of all ETH in circulation—around 27.9 million ETH valued at about $40 billion—is staked on the Beacon Chain. This represents substantial growth since staking withdrawals were enabled, though the rate of new stake deposits has recently slowed. This deceleration can be partially attributed to decreasing annual percentage rates (APR) for staking, which have declined from over 5.5% at the time of The Merge to approximately 3.5% as of recent measurements.
This yield compression stems from increased validator participation and reduced network transaction fees. When compared to traditional financial instruments like U.S. Treasury bonds offering 4-5% returns, Ethereum staking currently presents a higher opportunity cost for some investors. However, changing market conditions could quickly alter this dynamic, making on-chain yields more attractive again.
Lido's Role in Liquid Staking
Lido has played a pivotal role in democratizing Ethereum staking by removing technical barriers and capital requirements. Traditional Ethereum validation requires 32 ETH to run a validator node, putting participation out of reach for many users. Lido solves this problem by pooling resources from multiple stakeholders and delegating them to professional node operators.
When users deposit ETH into Lido's smart contracts, they receive stETH (staked ETH) tokens in return at a 1:1 ratio. These tokens represent a claim on both the initial deposit and any future staking rewards. This mechanism allows users to maintain liquidity while still participating in network validation and earning rewards.
With 8.9 million ETH staked through its protocol (worth approximately $16.8 billion), Lido dominates the liquid staking sector, commanding about 32% of all staked Ethereum. This market position has made it simultaneously the largest liquid staking protocol and one of the largest DeFi applications overall.
Centralization Concerns and Counterarguments
Lido's substantial market share has sparked intense debate within the Ethereum community regarding potential centralization risks. Critics argue that if any single liquid staking protocol or its node operators control too large a portion of staked ETH, it could threaten network security through:
- Increased centralization of validation resources
- Coordinated maximum extractable value (MEV) extraction
- Unfair slashing practices
- Potential for time-bandit attacks
However, Lido's structure differs significantly from a single entity controlling validation. The protocol currently distributes stakes across 38 independent node operators with enforced staking limits and geographical distribution requirements to maintain jurisdictional diversity.
Proponents argue that Lido's success stems from organic market dynamics and strong network effects rather than anti-competitive practices. They point to stETH's utility and adoption as evidence of genuine product-market fit. The debate ultimately centers on balancing accessibility with decentralization—a core Ethereum value proposition.
The stETH Network Effect
Lido's first-mover advantage and the innovative introduction of native yield through stETH have created powerful network effects that reinforce its market position. The stETH token has become integral to Ethereum's DeFi ecosystem, functioning as both a yield-bearing asset and versatile collateral.
The token's utility extends across multiple dimensions:
- Trading on both decentralized and centralized exchanges
- Collateral for lending and borrowing on platforms like Aave, Maker, and Compound
- Liquidity provision in automated market maker (AMM) pools
- Foundation for innovative financial products like synthetic stablecoins
This widespread integration creates a virtuous cycle where increased stETH utility drives further adoption, which in turn expands its ecosystem applications.
stETH as DeFi Collateral
stETH and its wrapped version (wstETH) have emerged as preferred collateral types across major lending protocols. On Aave v2, for example, stETH comprises approximately 33% of all deposited collateral—a significant increase since its introduction. During the same period, the share of wrapped ETH (WETH) declined from 39% to 21%.
This shift demonstrates how yield-bearing assets like stETH offer superior capital efficiency compared to non-yielding alternatives. Users can simultaneously earn staking rewards while deploying their assets as collateral for loans or other DeFi strategies.
The emergence of products using stETH as primary collateral for synthetic stablecoins and other instruments further demonstrates its integration depth. These developments parallel similar offerings in traditional finance that bring yield from assets like U.S. Treasuries on-chain.
stETH Trading and Liquidity
stETH maintains substantial liquidity across both decentralized and centralized trading venues. On decentralized exchanges, Curve Finance initially dominated stETH trading volume, reaching approximately $35 billion in monthly volume during May 2022. More recently, Uniswap has gained market share as its liquidity pools have deepened.
Centralized exchanges like OKX and Huobi also offer stETH trading pairs, though liquidity tends to be lower than on DeFi platforms. This multi-venue availability ensures users can easily enter or exit stETH positions according to their preferences.
Understanding stETH's Rebase Mechanism
stETH operates on a rebase mechanism that automatically adjusts token balances to reflect accumulated staking rewards. This design means users see their stETH balance increase daily without needing to claim rewards through transactions.
The rebase function works as follows:
balanceOf(account) = shares[account] * totalPooledEther / totalShares
In practical terms, this means that as the total amount of ETH managed by Lido's node operators grows through staking rewards, each stETH token represents a claim on a slightly larger portion of the pooled ETH.
While this provides a user-friendly experience similar to traditional savings accounts, the rebase mechanism presents integration challenges for protocols that don't natively support balance-changing tokens. This limitation led to the creation of wstETH (wrapped stETH), a non-rebasing version that maintains a fixed token count while tracking the value of stETH through an exchange rate mechanism.
wstETH has enabled stETH integration with major protocols including Maker, Aave v3, Compound v3, and Uniswap V3 that don't natively handle rebasing tokens.
Lido DAO Governance and LDO Token
Lido's governance structure represents both a strength and potential vulnerability within the protocol. The Lido DAO, governed by LDO token holders, maintains "root access" to critical protocol components including:
- Smart contract upgrades
- Node operator and oracle operator registries
- Management of withdrawal credentials
- Treasury oversight
This concentration of power combined with initially high LDO token concentration raised concerns about governance as a potential attack vector. Historical data shows significant holder concentration following Lido's December 2020 token distribution, though this has decreased over time.
The Herfindahl-Hirschman Index (HHI)—a measure of market concentration—for LDO token holders has declined from approximately 0.6 in early 2021 to 0.3 by October 2023, indicating improving distribution among holders.
To address governance concerns, proposals for dual governance models have emerged that would grant stETH holders veto power over LDO holder decisions. This approach aims to create better balance between different stakeholder groups within the ecosystem.

Frequently Asked Questions
What is liquid staking?
Liquid staking allows users to stake their cryptocurrency assets while maintaining liquidity through derivative tokens that represent their staked position. These tokens can be traded, used as collateral, or otherwise deployed in DeFi applications while continuing to earn staking rewards.
How does Lido maintain decentralization with 32% market share?
Lido distributes staked ETH across 38 independent node operators with enforced staking limits and geographical diversity requirements. The protocol's governance is also progressively decentralizing through mechanisms like potential dual governance that would give stETH holders veto power.
What is the difference between stETH and wstETH?
stETH is a rebasing token that automatically increases in balance to reflect staking rewards. wstETH is a wrapped version that maintains a constant token balance while tracking value through an exchange rate mechanism, making it compatible with protocols that don't support rebasing tokens.
Can stETH lose its 1:1 peg with ETH?
While designed to maintain a 1:1 peg, market conditions can sometimes cause temporary deviations. These are typically arbitraged away by traders, and the Shapella upgrade reduced peg volatility by enabling staking withdrawals.
How do I choose between solo staking and using Lido?
Solo staking requires 32 ETH and technical expertise to run a validator node but provides maximum decentralization. Liquid staking through Lido allows any amount of ETH to be staked without technical requirements but introduces smart contract risk and reliance on node operators.
What happens if Lido's node operators get slashed?
Lido's node operators are required to maintain insurance coverage against slashing events. If slashing occurs, the insurance fund covers losses before they affect stETH holders. Historical slashing incidents have been minimal and successfully covered by insurance.
Conclusion
Lido has become an integral component of Ethereum's staking ecosystem, significantly improving accessibility while generating important discussions about decentralization. The protocol's continued evolution—including governance improvements and mechanisms to distribute stake more widely—will be crucial for maintaining alignment with Ethereum's core values.
As the liquid staking landscape continues to develop, the balance between accessibility, yield generation, and network security remains paramount. The ongoing dialogue around Lido's position reflects a healthy ecosystem committed to finding optimal solutions that serve all stakeholders.
