# useUnwrap

Low-level mutation hook that requests an unwrap for a specific amount. You must finalize manually with [`useFinalizeUnwrap`](/protocol/sdk/api-references/react/usefinalizeunwrap.md).

{% hint style="info" %}
Most apps should use [`useUnshield`](/protocol/sdk/api-references/react/useunshield.md) instead, which orchestrates both steps (unwrap + finalize) in a single call.
{% endhint %}

## Import

```ts
import { useUnwrap } from "@zama-fhe/react-sdk";
```

## Usage

{% tabs %}
{% tab title="UnwrapButton.tsx" %}

```tsx
import { useUnwrap } from "@zama-fhe/react-sdk";

function UnwrapButton() {
  const { mutateAsync: unwrap, isPending } = useUnwrap("0xWrapper");

  const handleUnwrap = async () => {
    const { txHash } = await unwrap({ amount: 500n });
    console.log("Unwrap requested:", txHash);
    // Parse the UnwrapRequested event with findUnwrapRequested,
    // then pass unwrapRequestId to useFinalizeUnwrap.
  };

  return (
    <button onClick={handleUnwrap} disabled={isPending}>
      {isPending ? "Unwrapping..." : "Unwrap 500"}
    </button>
  );
}
```

{% endtab %}
{% endtabs %}

## Parameters

### address

`Address`

Address of the confidential wrapper contract. Passed positionally as the first argument.

```tsx
const { mutateAsync: unwrap } = useUnwrap("0xWrapper");
```

## Mutation variables

### amount

`bigint`

The amount of tokens to unwrap.

```tsx
await unwrap({ amount: 1000n });
```

## Return Type

The mutation resolves with `{ txHash: Hex, receipt: TransactionReceipt }`.

## 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.zama.org/protocol/sdk/api-references/react/useunwrap.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.
