IERC1155Receiver
Available since v3.1.
Methods
onERC1155BatchReceived
function onERC1155BatchReceived(address operator, address from, uint256[] ids, uint256[] values, bytes data) external nonpayable returns (bytes4)
Handles the receipt of a multiple ERC1155 token types. This function is called at the end of a safeBatchTransferFrom after the balances have been updated. NOTE: To accept the transfer(s), this must return bytes4(keccak256("onERC1155BatchReceived(address,address,uint256[],uint256[],bytes)")) (i.e. 0xbc197c81, or its own function selector).
Parameters
| Name | Type | Description |
|---|---|---|
| operator | address | The address which initiated the batch transfer (i.e. msg.sender) |
| from | address | The address which previously owned the token |
| ids | uint256[] | An array containing ids of each token being transferred (order and length must match values array) |
| values | uint256[] | An array containing amounts of each token being transferred (order and length must match ids array) |
| data | bytes | Additional data with no specified format |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | bytes4 | bytes4(keccak256("onERC1155BatchReceived(address,address,uint256[],uint256[],bytes)")) if transfer is allowed |
onERC1155Received
function onERC1155Received(address operator, address from, uint256 id, uint256 value, bytes data) external nonpayable returns (bytes4)
Handles the receipt of a single ERC1155 token type. This function is called at the end of a safeTransferFrom after the balance has been updated. NOTE: To accept the transfer, this must return bytes4(keccak256("onERC1155Received(address,address,uint256,uint256,bytes)")) (i.e. 0xf23a6e61, or its own function selector).
Parameters
| Name | Type | Description |
|---|---|---|
| operator | address | The address which initiated the transfer (i.e. msg.sender) |
| from | address | The address which previously owned the token |
| id | uint256 | The ID of the token being transferred |
| value | uint256 | The amount of tokens being transferred |
| data | bytes | Additional data with no specified format |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | bytes4 | bytes4(keccak256("onERC1155Received(address,address,uint256,uint256,bytes)")) if transfer is allowed |
supportsInterface
function supportsInterface(bytes4 interfaceId) external view returns (bool)
Returns true if this contract implements the interface defined by interfaceId. See the corresponding EIP section to learn more about how these ids are created. This function call must use less than 30 000 gas.
Parameters
| Name | Type | Description |
