Outline
If you are using Ethereum Signature Validator for verification, you need to restore the message that was used for the signature on the backend. Please add the following code to your backend. The reason for not sending the restored message directly from the frontend is to ensure that the message generated on the backend is revealed to be used for the signature. Without this assurance, there is a possibility of picking up any string and signature and impersonating someone else.
