Functions

balanceOf

Get the balance of an account's tokens.

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

Parameters

Returns

balanceOfBatch

Get the balance of multiple account/token pairs

function balanceOfBatch(address[] memory accounts, uint256[] memory ids) public view returns (uint256[] memory);

Parameters

Returns

setApprovalForAll

Enable or disable approval for a third party ("operator") to manage all of the caller's tokens.

MUST emit the ApprovalForAll event on success.

function setApprovalForAll(address operator, bool approved) public;

Parameters

isApprovedForAll

Queries the approval status of an operator for a given owner.

function isApprovedForAll(address account, address operator) public view returns (bool);

Parameters

Returns

safeTransferFrom

Transfers _value amount of an _id from the _from address to the _to address specified (with safety call).

*Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard).

• MUST revert if _to is the zero address.
• MUST revert if balance of holder for token _id is lower than the _value sent.
• MUST revert on any other error.
• MUST emit the TransferSingle event to reflect the balance change (see "Safe Transfer Rules" section of the standard).
• After the above conditions are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call onERC1155Received on _to and act appropriately (see "Safe Transfer Rules" section of the standard).*

function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes memory data) public;

Parameters

safeBatchTransferFrom

Transfers _values amount(s) of _ids from the _from address to the _to address specified (with safety call).

*Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard).

• MUST revert if _to is the zero address.
• MUST revert if length of _ids is not the same as length of _values.
• MUST revert if any of the balance(s) of the holder(s) for token(s) in _ids is lower than the respective amount(s) in _values sent to the recipient.
• MUST revert on any other error.
• MUST emit TransferSingle or TransferBatch event(s) such that all the balance changes are reflected (see "Safe Transfer Rules" section of the standard).
• Balance changes and events MUST follow the ordering of the arrays (_ids[0]/_values[0] before _ids[1]/_values[1], etc).
• After the above conditions for the transfer(s) in the batch are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call the relevant ERC1155TokenReceiver hook(s) on _to and act appropriately (see "Safe Transfer Rules" section of the standard).*

function safeBatchTransferFrom(
    address from,
    address to,
    uint256[] memory ids,
    uint256[] memory amounts,
    bytes memory data
) public;

Parameters

uri

Returns the URI for token type id. If the \{id\} substring is present in the URI, it must be replaced by clients with the actual token type ID.

function uri(uint256 id) public view override returns (string memory);

contractURI

function contractURI() external view override returns (string memory);

supportsInterface

Query if a contract implements an interface

Interface identification is specified in ERC-165. This function uses less than 30,000 gas.

function supportsInterface(bytes4 interfaceId) external pure virtual override(IERC165, SetBase) returns (bool);

Parameters

Returns

_supportsInterface

function _supportsInterface(bytes4 interfaceId) internal pure returns (bool);
