Lido has emerged as a cornerstone of Ethereum’s decentralized finance (DeFi) ecosystem, revolutionizing how users participate in staking. Since its inception in 2020, Lido has pioneered liquid staking, enabling ETH holders to earn staking rewards while maintaining liquidity through its derivative token, stETH. This article explores Lido’s origin, the problems it solves in native Ethereum staking, its architectural design, and how users interact with the protocol.
The Evolution of Ethereum Staking
Ethereum’s transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) marked a pivotal moment in blockchain history. The launch of the Beacon Chain in December 2020 initiated this shift, requiring validators to stake 32 ETH to secure the network. While this upgrade improved scalability and energy efficiency, it introduced significant limitations for users.
Native staking on Ethereum initially lacked flexibility:
- No withdrawals: Users could deposit ETH but couldn’t withdraw it or earned rewards until the Merge in September 2022.
- High entry barrier: The 32 ETH minimum excluded smaller participants.
- Illiquidity: Staked ETH was locked, unusable in DeFi protocols.
- Operational complexity: Running a validator node demands technical expertise and uptime.
These constraints created a clear need for innovation—enter Lido.

What Is Lido?
Lido is a decentralized liquid staking protocol launched in December 2020 by Vasilii Shapovalov, Konstantin Lomashuk, and a team of experienced developers. It addresses Ethereum’s staking limitations by allowing users to stake any amount of ETH and receive stETH in return—a token that represents their staked position and accrues rewards in real time.
Unlike traditional staking, where funds are locked, stETH can be:
- Traded on decentralized exchanges
- Used as collateral in lending protocols like Aave or MakerDAO
- Pooled in liquidity farms to earn additional yield
This seamless integration with DeFi makes Lido not just a staking solution, but a liquidity engine for the broader ecosystem.
With over 31% of all staked ETH on Ethereum, Lido dominates the liquid staking landscape. As of early 2025, stETH’s total value locked (TVL) exceeds **$22 billion**, far outpacing competitors like Rocket Pool (rETH), which holds less than $3 billion in TVL.
Core Components of Lido’s Architecture
Lido’s success stems from its robust, modular architecture designed for security, decentralization, and scalability. The system is composed of five key components:
1. Deposit and Staking Module
This is where user interaction begins. When a user deposits ETH into Lido, they instantly receive stETH at a 1:1 ratio. These deposits are pooled and used to activate new validators on the Beacon Chain once 32 ETH is accumulated.
For example:
- Alice deposits 1 ETH → receives 1 stETH
- Bob deposits 15 ETH → receives 15 stETH
- Tom deposits 16 ETH → receives 16 stETH
Together, their deposits form a full 32 ETH validator stake.
The protocol uses a registry of Node Operators—trusted entities responsible for running validator nodes securely. These operators provide public keys and withdrawal credentials, which are verified before deposits proceed.
2. Oracle Infrastructure
Oracles are critical for maintaining the accuracy of stETH’s value. Lido relies on a decentralized network of Oracle Nodes to report daily updates on:
- Total staked ETH
- Rewards earned across validator sets
- Exchange rate between stETH and ETH
This data ensures that stETH consistently reflects the underlying growth of staked assets. Without reliable oracles, the protocol would be vulnerable to mispricing and manipulation.
3. Consensus Mechanism
While Ethereum handles finality via its own consensus layer, Lido implements internal consensus rules governing:
- Validator activation order
- Reward distribution logic
- Withdrawal queue processing
These rules ensure fair treatment of all participants and prevent front-running or priority bias during high-demand periods such as post-Shanghai upgrades when withdrawal requests surged.
4. Withdrawal Mechanism
One of Lido’s most significant advancements came with the activation of withdrawals after the Shanghai upgrade in April 2023. Previously, stETH could not be redeemed for ETH.
Now, users can:
- Submit a withdrawal request
- Wait in a prioritized queue
- Receive ETH + accumulated rewards directly to their wallet
Behind the scenes, the Ejector Oracle compiles withdrawal messages from the consensus layer and triggers fund release through smart contracts. This mechanism restored full capital mobility to stakers—closing the loop on true liquidity.

5. Governance (Lido DAO)
Lido operates as a Decentralized Autonomous Organization (DAO) governed by holders of the LDO token, an ERC-20 governance token. Key decisions—including fee adjustments, node operator additions, and protocol upgrades—are proposed and voted on by the community.
For instance:
- The standard fee is 10% of staking rewards, split between node operators (for operational costs) and the DAO treasury (for development funding).
- This fee is adjustable via governance proposals.
Built on Aragon OS, the DAO framework ensures transparent, permissionless participation in protocol evolution.
Why Lido Stands Out in Liquid Staking
Lido’s dominance isn’t accidental—it results from solving real user pain points:
- Accessibility: No minimum stake required.
- Liquidity: stETH remains usable across DeFi.
- Security: Distributed node operators reduce centralization risk.
- Transparency: On-chain governance and public oracle reporting build trust.
Moreover, Lido has expanded beyond Ethereum, offering liquid staking solutions for Solana (stSOL), Polygon (stMATIC), Polkadot (stDOT), and Kusama (stKSM)—making it a multi-chain liquidity layer.
Frequently Asked Questions (FAQ)
Q: What is stETH and how does it gain value?
A: stETH is a liquid token representing staked ETH. It gains value as staking rewards accrue on the Beacon Chain. The exchange rate between ETH and stETH gradually increases over time.
Q: Can I lose money with stETH?
A: Yes—though rare, slashing events (penalties for validator misconduct) can reduce stETH value. However, Lido mitigates this through diversified node operators and insurance mechanisms.
Q: How often are rewards distributed?
A: Rewards are compounded continuously. The stETH/ETH ratio updates daily via oracle reports, so your balance grows automatically without claiming.
Q: Is Lido centralized?
A: While early versions relied on a small set of node operators, ongoing efforts in Distributed Validator Technology (DVT) aim to further decentralize control and eliminate single points of failure.
Q: Can I withdraw my ETH anytime?
A: Yes—after submitting a request, withdrawals are processed based on network capacity and queue length. Most withdrawals complete within days.
Q: How does Lido make money?
A: Lido charges a 10% fee on all staking rewards. These fees fund node operators and support protocol development via the DAO treasury.
Final Thoughts
Lido didn’t just respond to Ethereum’s limitations—it redefined what staking could be. By combining decentralization, liquidity, and DeFi interoperability, it created a new standard for participation in PoS networks.
As Ethereum continues to evolve with upgrades like Dencun and further scaling solutions, Lido remains at the forefront—adapting, innovating, and empowering users worldwide to earn yield without sacrificing flexibility.
Whether you're a casual investor or a DeFi power user, understanding Lido’s architecture provides insight into the future of blockchain-based finance.
