Token Support Facet

The Token Support Facet handles permits for ERC-20 and ERC-721 tokens and transfers for ERC-721 and ERC-1155 tokens.

Call Functions

Permit ERC-20

function permitERC20(
    IERC20Permit token,
    address owner,
    address spender,
    uint256 value,
    uint256 deadline,
    uint8 v,
    bytes32 r,
    bytes32 s
) public payable;

permitERC20 is a wrapper function for permit of ERC20Permit token.

Parameter Type Description
token IERC20Permit Token to permit.
owner address Owner of the token.
spender address Address to permit to spend the token.
value uint256 Token amount to permit.
deadline uint256 Expiration of signature (Unix time)
v uint8 Recovery ID.
r bytes32 ECDSA signature output.
s bytes32 ECDSA signature output.

Transfer ERC-721

function transferERC721(
    IERC721 token,
    address to,
    uint256 id
) external payable;

Execute an ERC-721 token transfer.

Parameter Type Description
token IERC721 Token address of the ERC-721.
to address Address being transferred to.
id uint256 ID of ERC-721 token to transfer.

Permit ERC-721

function permitERC721(
    IERC4494 token,
    address spender,
    uint256 tokenId,
    uint256 deadline,
    bytes memory sig
) external payable;

spender address Address to permit to spend the token.
tokenId uint256 ID of token to permit.
deadline uint256 Expiration of signature (Unix time).
sig bytes A valid secp256k1 or EIP-2098 signature from owner of the tokenId.

Transfer ERC-1155

function transferERC1155(
    IERC1155 token,
    address to,
    uint256 id,
    uint256 value
) external payable;

Parameter Type Description
token IERC1155 Token address of the ERC-1155.
to address Address being transferred to.
ids uint256[] Array of IDs of the ERC-155 token.
values uint256[] Array of amounts of ERC-1155s at id to transfer.
