SelfPermit
Self Permit
Functionality to call permit on any EIP-2612-compliant token for use in the route
Developer note: These functions are expected to be embedded in multicalls to allow EOAs to approve a contract and call a function that requires an approval in a single transaction.
Functions
selfPermit
function selfPermit(address token, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public payable
payable public
Permits this contract to spend a given token from `msg.sender` Developer note: The `owner` is always msg.sender and the `spender` is always address(this).
selfPermitIfNecessary
function selfPermitIfNecessary(address token, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external payable
payable external
Permits this contract to spend a given token from `msg.sender` Developer note: The `owner` is always msg.sender and the `spender` is always address(this). Can be used instead of #selfPermit to prevent calls from failing due to a frontrun of a call to #selfPermit
selfPermitAllowed
function selfPermitAllowed(address token, uint256 nonce, uint256 expiry, uint8 v, bytes32 r, bytes32 s) public payable
payable public
Permits this contract to spend the sender's tokens for permit signatures that have the `allowed` parameter Developer note: The `owner` is always msg.sender and the `spender` is always address(this)
selfPermitAllowedIfNecessary
function selfPermitAllowedIfNecessary(address token, uint256 nonce, uint256 expiry, uint8 v, bytes32 r, bytes32 s) external payable
payable external
Permits this contract to spend the sender's tokens for permit signatures that have the `allowed` parameter Developer note: The `owner` is always msg.sender and the `spender` is always address(this) Can be used instead of #selfPermitAllowed to prevent calls from failing due to a frontrun of a call to #selfPermitAllowed.
