Details

Implementation of the basic standard multi-token. See https://eips.ethereum.org/EIPS/eip-1155 Originally based on code by Enjin: https://github.com/enjin/erc-1155 Available since v3.1.

Methods

balanceOf

Solidity

function balanceOf(address account, uint256 id) external view returns (uint256)

Details

See {IERC1155-balanceOf}. Requirements: - account cannot be the zero address.

Parameters

Name	Type	Description
account	address	undefined
id	uint256	undefined

Returns

Name	Type	Description
_0	uint256	undefined

balanceOfBatch

Solidity

function balanceOfBatch(address[] accounts, uint256[] ids) external view returns (uint256[])

Details

See {IERC1155-balanceOfBatch}. Requirements: - accounts and ids must have the same length.

Parameters

Name	Type	Description
accounts	address[]	undefined
ids	uint256[]	undefined

Returns

Name	Type	Description
_0	uint256[]	undefined

isApprovedForAll

Solidity

function isApprovedForAll(address account, address operator) external view returns (bool)

Details

See {IERC1155-isApprovedForAll}.

Parameters

Name	Type	Description
account	address	undefined
operator	address	undefined

Returns

Name	Type	Description
_0	bool	undefined

safeBatchTransferFrom

Solidity

function safeBatchTransferFrom(address from, address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable

Details

See {IERC1155-safeBatchTransferFrom}.

Parameters

Name	Type	Description
from	address	undefined
to	address	undefined
ids	uint256[]	undefined
amounts	uint256[]	undefined
data	bytes	undefined

safeTransferFrom

Solidity

function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes data) external nonpayable

Details

See {IERC1155-safeTransferFrom}.

Parameters

Name	Type	Description
from	address	undefined
to	address	undefined
id	uint256	undefined
amount	uint256	undefined
data	bytes	undefined

setApprovalForAll

Solidity

function setApprovalForAll(address operator, bool approved) external nonpayable

Details

See {IERC1155-setApprovalForAll}.

Parameters

Name	Type	Description
operator	address	undefined
approved	bool	undefined

supportsInterface

Solidity

function supportsInterface(bytes4 interfaceId) external view returns (bool)

Details

See {IERC165-supportsInterface}.

Parameters

Name	Type	Description
interfaceId	bytes4	undefined

Returns

Name	Type	Description
_0	bool	undefined

uri

Solidity

function uri(uint256) external view returns (string)

Details

See {IERC1155MetadataURI-uri}. This implementation returns the same URI for all token types. It relies on the token type ID substitution mechanism https://eips.ethereum.org/EIPS/eip-1155#metadata[defined in the EIP]. Clients calling this function must replace the \{id\} substring with the actual token type ID.

Parameters

Name	Type	Description
_0	uint256	undefined

Returns

Name	Type	Description
_0	string	undefined

to indexed	address	undefined
ids	uint256[]	undefined
values	uint256[]	undefined

TransferSingle

Solidity

event TransferSingle(address indexed operator, address indexed from, address indexed to, uint256 id, uint256 value)

Parameters
