# signTransaction

> Function to sign a transaction using the connected Abstract Global Wallet.

The [AbstractClient](/abstract-global-wallet/agw-client/createAbstractClient)
includes a `signTransaction` method that can be used to sign a transaction using the connected Abstract Global Wallet.
Transactions are signed by the approved signer account (EOA) of the Abstract Global Wallet.

## Usage

```tsx theme={null}
import { useAbstractClient } from "@abstract-foundation/agw-react";

export default function SignTransaction() {
  const { data: agwClient } = useAbstractClient();

  async function signTransaction() {
    if (!agwClient) return;

    const signature = await agwClient.signTransaction({
      to: "0x273B3527BF5b607dE86F504fED49e1582dD2a1C6",
      data: "0x69",
    });
  }
}
```
