how to get v, r, s value in permit in erc20 token
Please provide more details to your question.
When I deploy permit function in erc20 there is v r and s variable and I don't understand these variable
These variable are v , r and s.
I'm assuming you're talking about OpenZeppelin's https://github.com/soliditylabs/ERC20-Permit/blob/main/contracts/ERC20Permit.sol
Here is some information on how to use the permit function. Its based on the draft but i don't think the method on how to implement it has changed.
