# Ether.fi Liquid

> Deposit eETH, weETH, or ETH into Ether.fi Liquid vaults on Ethereum and Optimism and exit through a withdrawal queue.

Ether.fi Liquid runs on the same Veda **BoringVault** infrastructure as the [Veda](/documentation/earn/defi/vaults/veda) and [Kinetiq](/documentation/earn/defi/vaults/kinetiq) integrations: you deposit an asset through a `Teller` contract and receive a **liquidETH** vault share, whose redemption value tracks an on-chain `Accountant` exchange rate.

<Note>
  This page covers the Liquid ETH vault only. Ether.fi's restaking product (eETH) is a separate yield.xyz integration, documented at [Restaking › Ether.fi](/documentation/earn/defi/restaking/etherfi).
</Note>

## Availability

| Network | Input tokens | Position token |
| - | - | - |
| Ethereum | eETH, weETH, WETH, native ETH (wrapped automatically) | liquidETH |
| Optimism | weETH, WETH, native ETH (wrapped automatically) | liquidETH |

Query [`GET /v1/yields?providers=etherfi`](/api-reference/YieldsController_getYields) for the vaults enabled for your project.

## Entering

Entering wraps native ETH first if you select it as the input token, approves the deposit asset to the BoringVault if needed, then calls the Teller's `deposit`, which mints liquidETH shares immediately. The transaction includes a minimum-mint check derived from the vault's exchange rate with a 0.5% slippage tolerance.

## Exiting

Exiting is a two-step request, not an instant redemption. It approves your liquidETH shares to the vault's withdrawal `Queue`, then submits `requestOnChainWithdraw`. The yield's `cooldownPeriod` is 3 days, actual maturity is set by the vault's on-chain withdrawal queue, and the request carries a 10-day deadline; it settles into **weETH**, not eETH, on both networks. While pending, the request is tracked as an `exiting` balance.

<Warning>
  A withdrawal request that reaches its 10-day deadline without being claimed has no cancellation path through the API today. Size withdrawal requests so they clear well inside the deadline.
</Warning>

## Rewards and position

The liquidETH share's value rises automatically as the Accountant's exchange rate grows; no claim step is needed. This vault has no separate reward token or `CLAIM_REWARDS` pending action.
