IERC1155Receiver
Functions
onERC1155Received
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).
function onERC1155Received(address operator, address from, uint256 id, uint256 value, bytes calldata data)
external
returns (bytes4);
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 |
|---|---|---|
<none> | bytes4 | bytes4(keccak256("onERC1155Received(address,address,uint256,uint256,bytes)")) if transfer is allowed |
onERC1155BatchReceived
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).
function onERC1155BatchReceived(
address operator,
address from,
uint256[] calldata ids,
uint256[] calldata values,
bytes calldata data
) external returns (bytes4);
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 |
|---|---|---|
<none> | bytes4 | bytes4(keccak256("onERC1155BatchReceived(address,address,uint256[],uint256[],bytes)")) if transfer is allowed |
