# use redeem

Mutation hook for redeeming vault shares for underlying assets via the Yo Gateway, with transaction tracking and automatic query invalidation.

```tsx
const { redeem, isPending, isSuccess, hash, instant, assetsOrRequestId } = useRedeem({ vault: 'yoETH' })
```

## Usage

```tsx
import { useRedeem } from '@yo-protocol/react'

function RedeemButton({ shares }: { shares: bigint }) {
  const {
    redeem,
    isPending,
    isSuccess,
    hash,
    instant,
    assetsOrRequestId,
    error,
    reset,
  } = useRedeem({
    vault: 'yoETH',
    onSubmitted: (hash) => console.log('Redeemed:', hash),
  })

  return (
    <div>
      <button onClick={() => redeem(shares)} disabled={isPending}>
        {isPending ? 'Redeeming...' : 'Redeem'}
      </button>

      {isSuccess && (
        <div>
          <p>Redemption complete! Tx: {hash}</p>
          {instant !== undefined && (
            <p>{instant ? 'Instant redemption' : `Pending — request ID: ${assetsOrRequestId}`}</p>
          )}
        </div>
      )}
      {error && (
        <p>
          Error: {error.message}
          <button onClick={reset}>Dismiss</button>
        </p>
      )}
    </div>
  )
}
```

{% hint style="info" %}
**Instant vs async redemptions**

The gateway `redeem` may complete instantly if sufficient liquidity is available. If not, the redemption remains pending for up to 24 hours. The `YoGatewayRedeem` event's `instant` field indicates which path was taken.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yo.xyz/integrations/integration-guides/sdk/react/hooks/use-redeem.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
