hi devs! How to keep track of used signature for stop multiple usage? Firstly I wanna do smth like this address => signature, but It can hold only last signature. So there is a way to cheap storage for signature or how to do it organize properly?

It's unclear what you mean. You want to allow the user to only submit a signature once and never again, or you want to just track the last signature that was used?

I wanna track all signature are used. So there is no chance to get back with old signature and claim money once again...
for now I have a mappting(signature => bool) it works as expected. But probably there is another way to do it?

That is probably as good as it gets, however, it seems futile. It is trivial to create thousands of addresses. You can never ensure individuality on blockchain without some kind of off-chain authentication.

cool, thanks a lot! it's simple project so I leave it as is =) I just want to be sure that I handle things properly.

We're all solidity devs, kind of hard to ignore this.

What does being a Solidity developer have to do with LUNA?

You can't figure out the one-degree-of-separation connection?
