Verifying real wallet ownership without gas: a signed-nonce pattern with viem + Express

1. 1Implement a signed-nonce pattern using Viem and Express to verify wallet ownership
2. 2Use a nonce to prevent replay attacks and ensure the signature is unique
3. 3Configure Express to handle signed requests and verify the signature
4. 4Test the implementation to ensure it works as expected
5. 5Apply this pattern to your own application to improve security and reduce gas costs
