Is this Smart Contract up to date?

Issue description

I am trying to play around with this Smart Contract, and I compiled it only to have a series of errors and squiggles. I tried to make sense of it by posting the log error to GPT, and here are some of the responses I found below which I can confirm in the code.

How did Argent compile this Smart Contract without getting Shadowing Function Declarations or Shadowing Variables in Inline Assembly? I also do hope there are instructions on how to personally adapt/use this Smart Contract.
