Hello fam
Can anyone help me with the signatures on one of my smart contracts?
I want to implement gas-less transactions in one of my contracts.
But struggling with the implementation of this.
Any help or resources will be of great help.

Smart Contract Programmer has some videos on it on youtube

I like his channel very gud straight to the point

The solidity part is not the problem actually
I am confused regarding the signing process.
I tried to sign a message via ethers and then I tried to recover the signer address via smart contract, but the came out was different from what I used to sign.

Try first with some simple example code you find online. Then expand to fulfill your specific needs.
Developing signature code is a real pain in the ass, since you can't really debug it - either the result is the right address or it simply isn't.

Yeah thanks
What I am currently trying to do is simply sign a string via ethers and then trying to recover the address via a contract.
But there's a lot of confusion around this.
1. What should the user sign? The message or the message hash or the bytes array of the message hash.
2. Do I need to use any EIP for this?

It's pretty confusing for me tbh

eip712 is needed when you want to sign a structured data, like a struct
to do a normal sign + recover you don't need any eip

Thanks
So in my case, I am trying to implement it in a multi-sig wallet, this wallet only works with funds and no other thing.
So what is the message that needs to be signed, and how will I ensure that the sign is used only once?
Can I dm you ?

for multi-sig wallets, i don't suggest to even write those from scratch but use directly safe.global

It's for learning purposes
I wanted to know the whole mechanism of sign based transactions
