safeBatchTransferFrom
function safeBatchTransferFrom(address from, address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable
xref:ROOT:erc1155.adoc#batch-operations[Batched] version of {safeTransferFrom}. Emits a {TransferBatch} event. Requirements: - ids and amounts must have the same length. - If to refers to a smart contract, it must implement {IERC1155Receiver-onERC1155BatchReceived} and return the acceptance magic value.
Parameters
| Name | Type | Description |
|---|
| from | address | undefined |
| to | address | undefined |
| ids | uint256[] | undefined |
| amounts | uint256[] | undefined |
| data | bytes | undefined |
safeTransferFrom
function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes data) external nonpayable
Transfers amount tokens of token type id from from to to. Emits a {TransferSingle} event. Requirements: - to cannot be the zero address. - If the caller is not from, it must have been approved to spend from's tokens via {setApprovalForAll}. - from must have a balance of tokens of type id of at least amount. - If to refers to a smart contract, it must implement {IERC1155Receiver-onERC1155Received} and return the acceptance magic value.
Parameters
| Name | Type | Description |
|---|
| from | address | undefined |
| to | address | undefined |
| id | uint256 | undefined |
| amount | uint256 | undefined |
| data | bytes | undefined |
setApprovalForAll
function setApprovalForAll(address operator, bool approved) external nonpayable
Grants or revokes permission to operator to transfer the caller's tokens, according to approved, Emits an {ApprovalForAll} event. Requirements: - operator cannot be the caller.
Parameters
| Name | Type | Description |
|---|
| operator | address | undefined |
| approved | bool | undefined |
supportsInterface
function supportsInterface(bytes4 interfaceId) external view returns (bool)
Returns true if this contract implements the interface defined by interfaceId. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[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 |
|---|
| interfaceId | bytes4 | undefined |
Returns
| Name | Type | Description |
|---|
| _0 | bool | undefined |
Events
ApprovalForAll
event ApprovalForAll(address indexed account, address indexed operator, bool approved)
Emitted when account grants or revokes permission to operator to transfer their tokens, according to approved.
Parameters
| Name | Type | Description |
|---|
account indexed | address | undefined |
operator indexed | address | undefined |
| approved | bool | undefined |
TransferBatch
event TransferBatch(address indexed operator, address indexed from, address indexed to, uint256[] ids, uint256[] values)
Equivalent to multiple {TransferSingle} events, where operator, from and to are the same for all transfers.
Parameters
| Name | Type | Description |
|---|
operator indexed | address | undefined |
from indexed | address | undefined |
to indexed | address | undefined |
| ids | uint256[] | undefined |
| values | uint256[] | undefined |
TransferSingle
event TransferSingle(address indexed operator, address indexed from, address indexed to, uint256 id, uint256 value)
Emitted when value tokens of token type id are transferred from from to to by operator.
Parameters
| Name | Type | Description |
|---|
operator indexed | address | undefined |
from indexed | address | undefined |
to indexed | address | undefined |
| id | uint256 | undefined |
| value | uint256 | undefined |
URI
event URI(string value, uint256 indexed id)
Emitted when the URI for token type id changes to value, if it is a non-programmatic URI. If an {URI} event was emitted for id, the standard https://eips.ethereum.org/EIPS/eip-1155#metadata-extensions[guarantees] that value will equal the value returned by {IERC1155MetadataURI-uri}.
Parameters
| Name | Type | Description |
|---|
| value | string | undefined |
id indexed | uint256 | undefined |
