# useConfidentialTransferFrom

Transfer confidential tokens on behalf of an owner who approved you as an operator.

Transfer confidential tokens on behalf of an owner who approved you as an operator. The sender must have been granted approval via [`useConfidentialSetOperator`](/protocol/sdk/api-references/react/useconfidentialsetoperator.md) before calling this hook. Automatically invalidates the [`useConfidentialBalance`](/protocol/sdk/api-references/react/useconfidentialbalance.md) cache on success.

## Import

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

## Usage

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

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

function OperatorTransfer({ tokenAddress }: { tokenAddress: `0x${string}` }) {
  const { mutateAsync: transferFrom, isPending } = useConfidentialTransferFrom(tokenAddress);

  async function handleTransfer() {
    const { txHash } = await transferFrom({ from: "0xOwner", to: "0xRecipient", amount: 500n });
    console.log("Transfer confirmed:", txHash);
  }

  return (
    <button onClick={handleTransfer} disabled={isPending}>
      {isPending ? "Transferring..." : "Transfer"}
    </button>
  );
}
```

{% endtab %}

{% tab title="config.ts" %}

```ts
// config.ts
import { createConfig as createZamaConfig } from "@zama-fhe/react-sdk/wagmi";
import { web } from "@zama-fhe/sdk/web";
import { sepolia } from "@zama-fhe/sdk/chains";
import type { FheChain } from "@zama-fhe/sdk/chains";
import { config as wagmiConfig } from "./wagmi";

const mySepolia = {
  ...sepolia,
  relayerUrl: "https://your-app.com/api/relayer/11155111",
} as const satisfies FheChain;

export const zamaConfig = createZamaConfig({
  chains: [mySepolia],
  wagmiConfig,
  relayers: { [mySepolia.id]: web() },
});

// In your app layout:
// <ZamaProvider config={zamaConfig}>
//   <App />
// </ZamaProvider>
```

{% endtab %}
{% endtabs %}

## Parameters

### address

`Address`

Contract address of the confidential token. Passed positionally as the first argument.

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

```tsx
const { mutateAsync: transferFrom } = useConfidentialTransferFrom("0xToken");
```

{% endtab %}
{% endtabs %}

***

## Mutation variables

The function passed to `mutate` / `mutateAsync` accepts:

### from

`Address`

Owner address whose tokens are being transferred. The connected wallet must have operator approval from this address.

### to

`Address`

Recipient address.

### amount

`bigint`

Number of tokens to transfer (in the token's base units). Encrypted before submission.

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

```tsx
await transferFrom({ from: "0xOwner", to: "0xRecipient", amount: 500n });
```

{% endtab %}
{% endtabs %}

## Return Type

The `data` property (after a successful mutation) is `{ txHash: Hex, receipt: TransactionReceipt }`.

* **`txHash`** -- Transaction hash submitted to the network.
* **`receipt`** -- Confirmed transaction receipt from the chain.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zama.org/protocol/sdk/api-references/react/useconfidentialtransferfrom.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
