I want to hard code an account address into the smart contract so I can use it for checking against sender/init_origin for authorization. I can see that an account address is a 32-byte sequence that is displayed as Base58check encoded. How can I make a constant variable for base58 encoded account address, e.g., 3ZFGxLtnUUSJGW2WqjMh1DDjxyq5rnytCwkSqxFTpsWSFdQnNn? I’ve tried to decode this one to hex and then use the macro hex! to convert it to a [u8, 32] array but the hex literal is 37 elements. What is the correct way to do this?
