Mint Permissions
Basic implementations (ERC721 and ERC1155) of a Mint Permissions contract that works with a singular creator contract are shown below. Note the approveMint function requires the sender to be the configured creator.
abstract contract ERC721CreatorMintPermissions is ERC165, AdminControl, IERC721CreatorMintPermissions {
address internal immutable _creator;
constructor(address creator_) {
require(ERC165Checker.supportsInterface(creator_, type(IERC721CreatorCore).interfaceId), "Must implement IERC721CreatorCore");
_creator = creator_;
}
/**
* @dev See {IERC165-supportsInterface}.
*/
function supportsInterface(bytes4 interfaceId) public view virtual override(ERC165, IERC165, AdminControl) returns (bool) {
return interfaceId == type(IERC721CreatorMintPermissions).interfaceId
|| super.supportsInterface(interfaceId);
}
/**
* @dev See {IERC721CreatorMintPermissions-approve}.
*/
function approveMint(address, address, uint256) public virtual override {
require(msg.sender == _creator, "Can only be called by token creator");
}
}
abstract contract ERC1155CreatorMintPermissions is ERC165, AdminControl, IERC1155CreatorMintPermissions {
address internal immutable _creator;
constructor(address creator_) {
require(ERC165Checker.supportsInterface(creator_, type(IERC1155CreatorCore).interfaceId), "Must implement IERC1155CreatorCore");
_creator = creator_;
}
/**
* @dev See {IERC165-supportsInterface}.
*/
function supportsInterface(bytes4 interfaceId) public view virtual override(ERC165, IERC165, AdminControl) returns (bool) {
return interfaceId == type(IERC1155CreatorMintPermissions).interfaceId
|| super.supportsInterface(interfaceId);
}
/**
* @dev See {IERC1155CreatorMintPermissions-approve}.
*/
function approveMint(address, address[] calldata, uint256[] calldata, uint256[] calldata) public virtual override {
require(msg.sender == _creator, "Can only be called by token creator");
}
}
Adding a Mint Permissions contract is similar to registering an extension. Add a mint permissions contract by calling the
setMintPermissions function and indicating the registered extension contract and mint permissions contract you wish to set.Last modified 1yr ago
