What Is Lido (LDO)?

Introduction

One of the main challenges facing Proof of Stake (PoS) blockchains is the lack of liquidity for assets locked in staking. When users lock their tokens to participate in staking, they lose immediate access to these funds until the lock-up period is over. This restriction prevents them from taking advantage of additional yield opportunities available through other DeFi protocols. The combination of these liquidity constraints, the technical complexity of validator setup, and high entry barriers—such as the 32 ETH minimum required on Ethereum—have discouraged many retail users who want to participate in PoS staking but lack the resources or technical expertise to do so.

Lido addresses these challenges and improves access to PoS staking by offering an innovative liquid staking solution. With Lido, users can keep their tokens liquid while simultaneously earning staking rewards. Lido has become one of the leading liquid staking solutions in the blockchain space, making it easy for millions of users to participate in these opportunities.

What Is Lido and What Is Its Purpose?

Lido is a liquid staking platform founded in 2020 that operates on several Proof of Stake blockchains. Originally developed for Ethereum (ETH), Lido has since expanded to other major PoS networks, including Solana (SOL), Polygon (MATIC), Polkadot (DOT), and Kusama (KSM).

Lido’s core mechanism is the 1:1 tokenization of staked assets. When users deposit their PoS tokens into Lido, they receive tokenized versions of their funds that exactly mirror their original deposits. This tokenization is crucial because it allows users to keep their assets liquid while staking. Tokenized assets can be freely used throughout the DeFi ecosystem, enabling users to earn additional yields alongside their original staking rewards. This innovation represents a paradigm shift—users can now help secure PoS networks without giving up economic opportunities. In essence, Lido acts as an intermediary that democratizes access to traditional staking.

How Does Lido Work?

Lido runs on a decentralized staking pool powered by smart contracts. When users deposit their PoS assets, the protocol automates several critical operations.

The main Lido smart contract manages user deposits and withdrawals, delegates funds to selected validator node operators, sets fee structures for staking rewards, and handles the minting and burning of tokens. It also keeps a complete registry of all active node operators, their validation keys, and the reward distribution history.

For example, in Ethereum staking, after the network’s move to Proof of Stake, Ethereum now requires a minimum of 32 ETH to operate an independent validator. Most users can’t meet this threshold. With Lido, anyone can stake even less than 1 ETH. When users deposit ETH, they receive stETH—an ERC-20 token that represents their deposit at a 1:1 ratio. Lido automatically mints stETH when funds are deposited and burns them when users withdraw ETH.

Deposited ETH is distributed among multiple node operators (validators) selected by the Lido network. Each validator gets a batch of 32 ETH to validate transactions on Ethereum’s consensus chain. Distributing assets among multiple validators is critical—it eliminates single points of failure that occur when delegating to just one validator. User funds remain secure within smart contracts, so validators cannot access them without authorization.

The Lido DAO is responsible for selecting, onboarding, and supporting validator addresses within the smart contract registry. Once onboarded, validators receive their public validation keys. Node operators also set up specific withdrawal addresses so users can retrieve their staked ETH after the Proof of Stake migration is complete.

Throughout this process, users retain full access to their stETH tokens. They can use stETH as collateral for DeFi loans, join yield farming, or hold their tokens to accumulate staking rewards—earning multiple yields at the same time.

The Lido DAO

Lido is governed by a Decentralized Autonomous Organization (DAO), ensuring protocol decisions are made transparently and in the best interests of participants. This decentralized system promotes genuine transparency and community control.

The Lido DAO oversees all liquid staking protocols, using smart contracts to set and enforce rules that support decentralized, efficient decision-making. Its responsibilities include managing fee structures, distributing rewards, and onboarding or removing node operators. This decentralized governance model keeps the protocol aligned with the broader community’s interests.

What Is LDO?

LDO is Lido’s native governance and utility token, implemented as an ERC-20 asset with a total supply of one billion tokens.

LDO serves two main roles in the Lido ecosystem. First, it rewards active network participants and incentivizes staking and engagement. Second, LDO gives holders governance rights in the Lido DAO, letting them vote directly on proposals and protocol changes. Lido’s governance is designed as a meritocracy—voting power is proportional to the amount of LDO each participant holds. The more LDO you own, the greater your influence over future protocol decisions.

Conclusion

Lido is a foundational innovation in DeFi. It solves the trade-off between network security and capital liquidity by enabling users to enjoy the benefits of traditional staking—security and economic rewards—without giving up liquidity or flexibility. This feature serves a wide range of users, from small holders looking to stake modest amounts to large PoS token holders seeking to maximize returns across multiple DeFi opportunities at once.

By removing complex staking requirements and significantly lowering the barriers to PoS participation, solutions like Lido make yield generation accessible to all. This enhanced accessibility continues to fuel DeFi’s growth, attracting new users and capital to PoS blockchains, while simultaneously strengthening network security through broader validator participation.
