# 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.md) and [Kinetiq](/documentation/earn/defi/vaults/kinetiq.md) 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.md).

## 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.

## 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.

## List the live yields

Copy this request to list the Ether.fi Liquid yields enabled for your project. Yield IDs change as markets and networks are added, so query the API rather than hardcoding them.

```bash theme={null}
curl "https://api.yield.xyz/v1/yields?providers=etherfi&limit=100" \
  -H "x-api-key: $YIELD_API_KEY"
```
