Self Permit
Functionality to call permit on any EIP-2612-compliant token for use in the route
function selfPermit(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).
| Name | Type | Description |
|---|---|---|
| token | address | The address of the token spent |
| value | uint256 | The amount that can be spent of token |
| deadline | uint256 | A timestamp, the current blocktime must be less than or equal to this 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` |
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

| s | bytes32 | Must produce valid secp256k1 signature from the holder along with `r` and `v` |
function selfPermitAllowed(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)
| Name | Type | Description |
|---|---|---|
| token | address | The address of the token spent |
| nonce | uint256 | The current nonce of the owner |
| expiry | uint256 | The timestamp at which the permit is no longer valid |
| 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` |

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.
