I'm trying to interact with a smart contract in python. With Metamask i can see, that there is a signature trasferred to verify my wallet. Now the point is how to calculate this signature to use a python script. On the contract side, the signature will be compared with a calculated signature on the server:
bytes32 message = keccak256(abi.encodePacked(msg.sender, address(this))); require(verifier.verify(message, _signature), "INVALID_SIGNATURE");
function verify(bytes32 _message, bytes memory _signature) external view returns (bool);
I assume that msg.sender will be my wallet adress but not sure about the other one?
Any links to read more about this topic would also be helpful! Thank you.
