Liquid Stake ETH with EtherFi

WHAT IT DOES

This tool enables you to liquid stake native ETH with EtherFi, a leading liquid staking protocol built on EigenLayer. It reads your current ETH balance on Ethereum Mainnet, the EtherFi staking contract details, and the current gas price to provide an accurate cost estimate before you commit. The tool then constructs and submits a transaction to the EtherFi LiquidityPool contract, depositing your specified amount of ETH and receiving eETH (EtherFi's liquid staking token) in return.

Liquid staking allows you to stake your ETH and earn staking rewards while receiving a liquid token (eETH) that can be used in DeFi applications, traded, or held. eETH represents your staked ETH and automatically accrues staking rewards over time, increasing in value relative to ETH. The tool uses the official EtherFi contract and is specifically designed for Ethereum Mainnet (chain ID 1), where EtherFi is deployed.

HOW TO USE

Connect your wallet using the "connect" button. Ensure you are connected to Ethereum Mainnet (chain ID 1) — the tool will display your current chain ID, ETH balance, and any existing eETH balance. Enter the amount of ETH you wish to liquid stake in the input field. The tool will display the staking contract address and estimate the gas cost for the deposit transaction.

Review the stake summary, then click "liquid stake ETH with EtherFi" to sign and submit the transaction through your wallet. The tool will wait for confirmation and display the transaction details on Etherscan. After the transaction is confirmed, you will receive eETH in your wallet representing your staked ETH position. Your eETH balance will automatically accrue staking rewards over time, and you can monitor it through the tool's balance display.

TECHNICAL MECHANISM — ETHERFI LIQUID STAKING

The tool interacts with the EtherFi LiquidityPool contract, which manages the deposit of native ETH and the minting of eETH tokens. The contract's deposit() function accepts ETH as value and handles the underlying mechanics of depositing ETH into EigenLayer's restaking infrastructure through EtherFi's integrated staking system.

When you deposit ETH through the LiquidityPool, the contract forwards the ETH to EigenLayer's restaking contracts, where it is staked to secure Actively Validated Services (AVSs). In return, the contract mints eETH tokens at a 1:1 ratio with the deposited ETH, minus any protocol fees. eETH is an ERC-20 token that represents your claim on the underlying staked ETH plus accumulated rewards. The value of eETH increases over time as staking rewards are accrued, allowing you to benefit from staking yields while maintaining the liquidity to use eETH in DeFi applications, such as lending, borrowing, or providing liquidity. The withdrawal process requires burning eETH and going through EigenLayer's withdrawal queue, which can take several days.

WHAT IT CANNOT SEE

This tool cannot estimate exact gas costs without a live RPC call, and gas prices on Ethereum Mainnet may change between quoting and execution. It cannot guarantee yield rates or APR, as these depend on network conditions and EigenLayer rewards. The tool cannot verify the staking contract address is correct beyond the pre-configured mapping, and if the mapping becomes outdated, the transaction could fail or be sent to the wrong contract. It cannot cancel a transaction once submitted, and if the transaction fails due to gas issues or contract errors, you may still pay gas fees. The tool cannot interact with non-Ethereum chains or provide immediate withdrawal functionality — withdrawals require burning eETH and going through EigenLayer's multi-day withdrawal queue. The tool cannot handle staking of tokens other than native ETH.

PLEASE NOTE — ETHEREUM MAINNET ONLY

This tool works exclusively on Ethereum Mainnet (chain ID 1). You must be connected to Ethereum Mainnet to use this tool. It does not support other networks or layer 2 solutions. The tool only stakes native ETH and returns eETH — it does not support other assets. eETH is a liquid staking token that accrues rewards automatically, but it also carries the risks of the underlying staking protocol, including slashing risks from EigenLayer AVSs. Always verify the staking contract address before submitting a transaction. This tool provides a simple deposit interface; withdrawals are not supported and must be performed through EtherFi's official mechanisms.
