ERC1155Upgradeable

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​

NameTypeDescription
accountaddressundefined
iduint256undefined

Returns​

NameTypeDescription
_0uint256undefined

balanceOfBatch​

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

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

Parameters​

NameTypeDescription
accountsaddress[]undefined
idsuint256[]undefined

Returns​

NameTypeDescription
_0uint256[]undefined

isApprovedForAll​

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

See {IERC1155-isApprovedForAll}.

Parameters​

NameTypeDescription
accountaddressundefined
operatoraddressundefined

Returns​

NameTypeDescription
_0boolundefined

safeBatchTransferFrom​

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

See {IERC1155-safeBatchTransferFrom}.

Parameters​

NameTypeDescription
fromaddressundefined
toaddressundefined
idsuint256[]undefined
amountsuint256[]undefined
databytesundefined

safeTransferFrom​

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

See {IERC1155-safeTransferFrom}.

Parameters​

NameTypeDescription
fromaddressundefined
toaddressundefined
iduint256undefined
amountuint256undefined
databytesundefined

setApprovalForAll​

function setApprovalForAll(address operator, bool approved) external nonpayable

See {IERC1155-setApprovalForAll}.

Parameters​

NameTypeDescription
operatoraddressundefined
approvedboolundefined

supportsInterface​

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

See {IERC165-supportsInterface}.

Parameters​

NameTypeDescription
interfaceIdbytes4undefined

Returns​

NameTypeDescription
_0boolundefined

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​

NameTypeDescription
_0uint256undefined

Returns​

NameTypeDescription
_0stringundefined

operator indexedaddressundefined
approvedboolundefined

Initialized​

event Initialized(uint8 version)

Parameters​

NameTypeDescription
