Abi Encode with Signature - String memory as parameter to function

Question

I'm trying to do

abi.encodeWithSignature(
                "mint(address, string **memory**)",
                receiverAddress,
                tokenURI
            )

The function definition is like this:

function mint(address to, string memory tokenURI) public {
        _safeMint(to, tokenId);
        _setTokenURI(tokenId, tokenURI);
        unchecked {
            tokenId++;
        }
    }

Do I need to add memory keyword while encoding or not? It will be a great help if someone can explain me that. Thanks in advance.

Answer 1

You don’t need to add memory keyword. Also, you’ve to remove any spaces.

So, it should be:

abi.encodeWithSignature(
                "mint(address,string)",
                receiverAddress,
                tokenURI
            );
