# linkToAgw

> Function to link an Ethereum Mainnet wallet to an Abstract Global Wallet.

The [AbstractClient](/abstract-global-wallet/agw-client/createAbstractClient) includes a `linkToAgw` method that can be used to create a link between an Ethereum Mainnet wallet and an Abstract Global Wallet.

## Usage

```tsx theme={null}
import { linkableWalletActions } from "@abstract-foundation/agw-client";
import { createWalletClient, custom } from "viem";
import { sepolia, abstractTestnet } from "viem/chains";

export default function LinkWallet() {
  async function linkAgwWallet() {
    // Initialize a Viem Wallet client: (https://viem.sh/docs/clients/wallet)
    // And extend it with linkableWalletActions
    const client = createWalletClient({
      chain: sepolia,
      transport: custom(window.ethereum!),
    }).extend(linkableWalletActions());

    // Call linkToAgw with the AGW address 
    const { l1TransactionHash, getL2TransactionHash } =
      await client.linkToAgw({
        agwAddress: "0x...", // The AGW address to link to
        enabled: true, // Enable or disable the link
        l2Chain: abstractTestnet, 
      });

    // Get the L2 transaction hash once the L1 transaction is confirmed
    const l2Hash = await getL2TransactionHash();
  }

  return <button onClick={linkAgwWallet}>Link Wallet</button>;

}
```

## Parameters
