Current Behavior

When using viem with wagmi to interact with OP-Stack and extending the client with walletActionsL1(), everything works fine when conducting transactions directly with the extended wallet client.

However, when connecting via WalletConnect (e.g., MetaMask or TrustWallet), attempting to execute a bridge transaction fails with the following error:

`TransactionExecutionError: The requested method and/or account has not been authorized by the user.

Expected Behavior

• The transaction should proceed without an authorization error after connecting via WalletConnect.
• The extended wallet client should function the same way as with direct wallet connections.

Steps To Reproduce

I've set up a wagmi/next playground with an OP-Stack section reproducing the issue:
🔗 GitHub Repository

1. Connect using WalletConnect (e.g., MetaMask or TrustWallet).
2. Attempt to execute a bridge transaction via the extended client.
3. Observe the error message related to unauthorized account/method.
