Curve Finance is an Automated Market Maker (AMM) and decentralized exchange (DEX) that specializes in stablecoin and pegged-asset trading. It is designed to offer extremely low fees and minimal slippage for traders. The platform operates using liquidity pools, enabling peer-to-peer token swaps while rewarding those who supply assets to these pools. Liquidity providers earn a share of the trading fees and often receive additional token rewards. As a non-custodial protocol, Curve ensures you retain full control of your assets throughout the process.
One of the most liquid markets on Curve is the stETH/ETH pool. This allows users who stake Ethereum with Lido to seamlessly swap between stETH and ETH with high efficiency and low cost.
In this guide, you will learn how to supply liquidity to the stETH/ETH pool on Curve Finance. We will cover the entire process, from initial deposit to reward claiming, and address common questions about managing your liquidity position.
Understanding Curve Finance and Its stETH Pool
The stETH pool on Curve is a liquidity pool containing both stETH and ETH. Users interact with this pool to exchange one token for the other with minimal price impact. Every trade executed within the pool generates a fee. These fees are then distributed to the individuals who have provided liquidity to the pool, paid out in the form of CRV tokens.
When you deposit assets into the stETH/ETH pool, you receive LP (Liquidity Provider) tokens in return. These tokens represent your share of the total liquidity in the pool. You can then take a further step by staking these LP tokens in a Curve gauge. This action amplifies your rewards, allowing you to earn a portion of the trading fees generated by the pool.
Benefits of Providing Liquidity on Curve
Providing liquidity is crucial for the healthy functioning of any decentralized exchange. For stETH holders, the Curve pool offers a highly efficient alternative to the native Ethereum unstaking process. Without sufficient liquidity, swapping stETH for ETH would be costly and slow, potentially requiring users to enter a withdrawal queue on the Beacon Chain.
By becoming a liquidity provider, you help solve this problem. In return for your service, you are incentivized with trading fees and potential bonus rewards. This creates a sustainable ecosystem where Lido stakers can maintain liquidity and flexibility with their staked assets. It’s a way to earn additional yield on top of the standard staking rewards that stETH accrues.
How to Provide Liquidity to the Curve stETH/ETH Pool
Step-by-Step Deposit Process
To begin providing liquidity, you first need to connect your Web3 wallet to the Curve interface.
- Navigate to the correct stETH pool deposit page on the Curve Finance website.
- Connect your preferred Ethereum wallet (like MetaMask or WalletConnect).
- You will see an interface to deposit either ETH, stETH, or a combination of both. The system will automatically balance your deposit according to the pool's required ratio.
- After approving the transaction in your wallet, your liquidity will be added. You will receive stETH/ETH LP tokens (steCRV) in return, which represent your share of the pool.
Upon confirmation, these LP tokens are often automatically staked into the gauge to being earning CRV rewards. If they are not, you will need to manually stake them.
Important Considerations When Depositing
It’s vital to understand that when you provide liquidity, you are exposed to a concept known as impermanent loss. This occurs when the price of your deposited assets changes compared to when you deposited them. While the stable nature of the stETH/ETH pair minimizes this risk, it is not zero.
Furthermore, remember that by holding stETH in the Curve pool, you continue to earn Ethereum staking rewards. Your underlying stETH balance continues to rebase, meaning your overall share of the pool may change over time, but you do not lose your staking yield.
Managing Your Liquidity and Claiming Rewards
Earning and Claiming CRV Rewards
Trading fees are accrued automatically with every swap that occurs in the pool. These fees are continuously added to the value of your LP token share. There is no need to manually claim these base fees; they are realized when you withdraw your liquidity.
The additional CRV token rewards for staking your LP tokens in the gauge also accumulate in real-time. To claim these CRV rewards, you typically need to visit a specific "Claim" section on the Curve interface and execute a transaction.
How to Withdraw Your Assets
Curve offers full flexibility to unstake and withdraw your assets at any time. The process involves two potential steps:
- Unstaking: If your LP tokens are staked in a gauge, you must first unstake them to stop earning CRV rewards. This moves the LP tokens back to your wallet.
- Withdrawing: Once you have the LP tokens in your wallet, you can withdraw them from the liquidity pool. This action burns your LP tokens and returns your underlying assets—plus any accrued trading fees—to your wallet.
When you withdraw, you can often choose to receive your assets as a combination of stETH and ETH, or primarily as one token, though this may incur some slippage. After confirming the withdrawal transaction in your wallet, the assets will be transferred from the pool back to your wallet address.

Frequently Asked Questions
What exactly is stETH?
stETH is a liquid staking token issued by Lido. When you stake ETH with Lido, you receive stETH in return. This token dynamically represents your staked ETH and the rewards it earns, which compound daily through rebasing.
What are the main advantages of providing stETH liquidity on Curve?
The primary advantage is earning additional yield. You receive two streams of income: the standard staking rewards from your stETH and a share of the trading fees from the Curve pool. This is often called "yield stacking."
Are there risks involved in being a liquidity provider?
Yes, providing liquidity carries risks. The main risks include smart contract vulnerabilities (though Curve's contracts are extensively audited), impermanent loss (minimized in stable pairs but still present), and potential changes in reward emissions. Always conduct your own research before committing funds.
Can I lose my stETH by providing liquidity?
The stETH itself does not vanish. However, the value of your liquidity position can fluctuate based on market activity and the relative price of ETH and stETH. You maintain ownership of your assets via the LP tokens.
How often are rewards distributed?
Trading fees are added to the pool continuously, increasing the value of your LP tokens. CRV token rewards for gauge staking are also accrued continuously and can be claimed manually at any time.
Do I need to unstake to claim my CRV rewards?
No, you can usually claim your accumulated CRV rewards without unstaking your LP tokens. Unstaking is only required when you want to remove your liquidity from the pool entirely.
