Custom wrap token
Bridge calls
mint(address _to, uint256 _tokenId) for ERC721 tokensAnd calls
mint(address _to, uint256 _tokenId, bytes memory data and mintBatch(address _to, uint256[] memory _ids, uint256[] memory _amounts, bytes memory _data) for ERC1155 tokens.So your L2 wrap token should grant the function permissions to our L2 bridge address.
