ERC 1155

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

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

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

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

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

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

See {IERC1155-isApprovedForAll}.

Parameters

Name	Type	Description
account	address	undefined
operator	address	undefined

Returns

Name	Type	Description
_0	bool	undefined

safeBatchTransferFrom

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

See {IERC1155-safeBatchTransferFrom}.

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

See {IERC1155-safeTransferFrom}.

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

See {IERC1155-setApprovalForAll}.

Parameters

Name	Type	Description
operator	address	undefined
approved	bool	undefined

supportsInterface

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

See {IERC165-supportsInterface}.

Parameters

Name	Type	Description
interfaceId	bytes4	undefined

Returns

Name	Type	Description
_0	bool	undefined

uri

function uri(uint256) external view returns (string)

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

Events

ApprovalForAll

event ApprovalForAll(address indexed account, address indexed operator, bool 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)

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)

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)

Parameters
