# Ethena

> Stake USDe with Ethena on Ethereum for sUSDe, then exit through a cooldown (currently 7 days) and a claim action.

The Ethena integration deposits USDe into Ethena's staking vault on Ethereum. You receive sUSDe, an ERC-4626 share whose redemption value in USDe rises as staking rewards accrue.

## Availability

| Network | Input token | Position token |
| - | - | - |
| Ethereum | USDe | sUSDe |

The yield ID is the fixed value `ethena-usde-staking`. Check its status with [`GET /v1/yields?providers=ethena`](/api-reference/YieldsController_getYields) (project-scoped).

## Entering

An enter action approves USDe and deposits it into the sUSDe vault in the same flow. sUSDe is minted to your address immediately, with no warmup period.

## Exiting

Exiting sUSDe is a two-step flow, not an instant redeem:

1. The exit action calls the vault's `cooldownShares` function, which converts your sUSDe into a pending unstake and starts the cooldown. Your USDe is not returned yet.
2. During the cooldown the position is an `exiting` balance with no pending actions. Once the cooldown ends, it is returned as a `withdrawable` balance with a `CLAIM_UNSTAKED` pending action. Submitting it calls the vault's `unstake` function, which transfers the USDe to your address.

<Warning>
  The cooldown is set by the sUSDe contract (currently 7 days, reported in the yield's `cooldownPeriod`) and cannot be skipped. After it ends, the USDe is not sent automatically: you must submit the `CLAIM_UNSTAKED` pending action to release it. Track the cooldown and the claimable balance through [balances and positions](/documentation/earn/core-concepts/balances-positions).
</Warning>

## Rewards and position

Staking rewards compound automatically into the sUSDe share price; there is no separate claim step for the base yield. Ethena also credits Sats, a points-program balance tracked alongside your staked position, with no claim action of its own.
