Returns

Name	Type	Description
_0	uint256	Current nonce of an address

permit

Grants or revokes the approval for an operator to transfer any of the owner's tokens using their signature

Solidity

function permit(address owner, address operator, bool approved, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external nonpayable

Parameters

deadline	uint256	Expiry of the signature, as a timestamp
v	uint8	Must produce valid secp256k1 signature from the holder along with r and s
r	bytes32	Must produce valid secp256k1 signature from the holder along with v and s
s	bytes32	Must produce valid secp256k1 signature from the holder along with r and v

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

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
