    • An object containing the signature. This function validates the signer and payload, then determines the version of the EIP-712 message being signed. It then uses the appropriate method to sign the message and returns the signature. The function can handle both V1 and V3/V4 versions of EIP-712 messages. Note: It is assumed that the addresses are in the correct format and have already been validated for length and character set.
