# useSignatureRequest

Hook to send JSON-RPC signing requests through the Wallet Services overlay. Unlike signing directly with `provider`, this presents a human-readable confirmation screen to the user before executing the operation.

### Import[​](#import "Direct link to Import")

```
import { useSignatureRequest } from '@web3auth/react-native-sdk'

```

### Usage[​](#usage "Direct link to Usage")

```
import { useSignatureRequest } from '@web3auth/react-native-sdk'
import { useWeb3Auth } from '@web3auth/react-native-sdk'
import { ethers } from 'ethers'

function SigningView() {
  const { request, loading, error } = useSignatureRequest()
  const { provider } = useWeb3Auth()

  const getAddress = async () => {
    const ep = new ethers.BrowserProvider(provider!)
    const signer = await ep.getSigner()
    return await signer.getAddress()
  }

  const signPersonalMessage = async () => {
    const address = await getAddress()
    const message = 'Hello from Web3Auth!'
    // Presents a signing confirmation in the Wallet Services overlay
    const signature = await request('personal_sign', [
      ethers.hexlify(ethers.toUtf8Bytes(message)),
      address,
    ])
    console.log('Signature:', signature)
  }

  const sendTransaction = async () => {
    const address = await getAddress()
    const txHash = await request('eth_sendTransaction', [
      {
        from: address,
        to: '0x0000000000000000000000000000000000000001',
        value: ethers.toBeHex(ethers.parseEther('0.001')),
        gasLimit: ethers.toBeHex(21000),
      },
    ])
    console.log('Transaction hash:', txHash)
  }

  return (
    <View>
      <Button title="Sign message" disabled={loading} onPress={signPersonalMessage} />
      <Button title="Send ETH" disabled={loading} onPress={sendTransaction} />
      {error && <Text>{error.message}</Text>}
    </View>
  )
}

```

### Return type[​](#return-type "Direct link to Return type")

#### `request`[​](#request "Direct link to request")

`(method: string, params: unknown[]) => Promise<unknown>`

Sends a JSON-RPC call through the Wallet Services overlay. The user sees a confirmation screen before the operation is executed. Returns the JSON-RPC result value on success.

Common `method` values:

| Method               | Description                              |
| -------------------- | ---------------------------------------- |
| personal_sign        | Sign a personal message (EIP-191).       |
| eth_signTypedData_v4 | Sign typed structured data (EIP-712).    |
| eth_sendTransaction  | Send a transaction.                      |
| eth_signTransaction  | Sign a transaction without broadcasting. |

#### `loading`[​](#loading "Direct link to loading")

`boolean`

`true` while the request is pending user confirmation or execution.

#### `error`[​](#error "Direct link to error")

`Web3AuthError | null`

Error from the most recent `request` call, or `null` if successful.
