Cancelling Orders
All orders, whether off-chain or on-chain, can only be cancelled on-chain. The following contract functions are used to cancel individual ERC721 and ERC1155 orders.
/// @dev Cancel a single ERC721 order by its nonce. The caller
/// should be the maker of the order. Silently succeeds if
/// an order with the same nonce has already been filled or
/// cancelled.
/// @param orderNonce The order nonce.
function cancelERC721Order(uint256 orderNonce)
external;
/// @dev Cancel a single ERC1155 order by its nonce. The caller
/// should be the maker of the order. Silently succeeds if
/// an order with the same nonce has already been filled or
/// cancelled.
/// @param orderNonce The order nonce.
function cancelERC1155Order(uint256 orderNonce)
external;
Note that if there are multiple outstanding orders with the same nonce, calling
cancelERC721Order or cancelERC1155Order would cancel all those orders.The following functions can be used to cancel multiple orders.
/// @dev Cancel multiple ERC721 orders by their nonces. The caller
/// should be the maker of the orders. Silently succeeds if
/// an order with the same nonce has already been filled or
/// cancelled.
/// @param orderNonces The order nonces.
function batchCancelERC721Orders(uint256[] calldata orderNonces)
external;
/// @dev Cancel multiple ERC1155 orders by their nonces. The caller
/// should be the maker of the orders. Silently succeeds if
/// an order with the same nonce has already been filled or
/// cancelled.
/// @param orderNonces The order nonces.
function batchCancelERC1155Orders(uint256[] calldata orderNonces)
external;
