If we want to use all lowercase (un-checksummed) c-chain addrs we can do this:

import {Strings} from "@openzeppelin/contracts/utils/Strings.sol";
// Given an address, convert to its string (lowercase) format, and hash a message like the avalanche wallet would do
function hashMessage(address addr) public pure returns (bytes32) {
	bytes memory header = bytes("\x1AAvalanche Signed Message:\n");
	// len of an ascii addr is 42 bytes
	uint32 addrLen = 42;
	bytes memory addrStr = bytes(Strings.toHexString(uint160(addr), 20));
	return sha256(abi.encodePacked(header, addrLen, addrStr));
}
