SelfPermit
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
selfPermit(address,uint256,uint256,uint8,bytes32,bytes32) payable public
Permits this contract to spend a given token from `msg.sender`
| 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` |
