Are there any guides or examples I could reference for how to sign a message?

Expert

I have been looking for tools/guides for calling the `SupplywithPermit` function for Aave v3 pool and I thought I would ask for help in here since i could not find anything else. I was able to get the approve and supply working but rather than processing two transactions and paying twice as many fees I am trying the "signed message" option however i am having trouble setting up the code to get the V R S params. Are there any guides or examples I could reference for how to sign a message?

To use the permit method you'll need to generate the data to sign, sign with the wallet, then pass this signature into the `supplyWithPermit `function. There is an example of this in the aave-ui repo [here](https://github.com/aave/aave-ui/blob/6af38149402285256aba9363272288c3b327ddbd/src/modules/deposit/screens/DepositConfirmation/index.tsx#L124);
