This is a Coinbase Wallet-specific method and may not be available in other wallets.
After successful connection, the wallet will emit connection events and provide access to account information.
When using the signInWithEthereum capability, always generate a fresh, unique nonce for each authentication attempt to prevent replay attacks. The signature can be verified on your backend using libraries like viem.

​
Usage with Capabilities

You can use the wallet_connect with the signInWithEthereum capability to authenticate the user.
