IERC721Permit_v4

Git Source | Generated with forge doc

Extension to ERC721 that includes a permit function for signature based approvals

Functions

permit

Approve of a specific token ID for spending by spender via signature

payable so it can be multicalled with NATIVE related actions

function permit(address spender, uint256 tokenId, uint256 deadline, uint256 nonce, bytes calldata signature)
    external
    payable;

Parameters

Name	Type	Description
spender	address	The account that is being approved
tokenId	uint256	The ID of the token that is being approved for spending
deadline	uint256	The deadline timestamp by which the call must be mined for the approve to work
nonce	uint256	a unique value, for an owner, to prevent replay attacks; an unordered nonce where the top 248 bits correspond to a word and the bottom 8 bits calculate the bit position of the word
signature	bytes	Concatenated data from a valid secp256k1 signature from the holder, i.e. abi.encodePacked(r, s, v)

permitForAll

Set an operator with full permission to an owner's tokens via signature

payable so it can be multicalled with NATIVE related actions

function permitForAll(
    address owner,
    address operator,
    bool approved,
    uint256 deadline,
    uint256 nonce,
    bytes calldata signature
) external payable;

Parameters

Name	Type	Description
owner	address	The address that is setting the operator
operator	address	The address that will be set as an operator for the owner
approved	bool	The permission to set on the operator
deadline	uint256	The deadline timestamp by which the call must be mined for the approve to work
nonce	uint256	a unique value, for an owner, to prevent replay attacks; an unordered nonce where the top 248 bits correspond to a word and the bottom 8 bits calculate the bit position of the word
signature	bytes	Concatenated data from a valid secp256k1 signature from the holder, i.e. abi.encodePacked(r, s, v)
