self.sign_url = "https://builder-signing-server.vercel.app/sign"

I dont think this is malicious, it just stood out to me.

What is this doing exactly?
self.sign_url = "https://builder-signing-server.vercel.app/sign"

And what would you do if you dont want to rely on a third party signing app? Can you do it with polymarket builder api and set this up oneself?

I spun a signing server to keep my builder creds private. you can instantiate PolymarketGaslessWeb3Client with builder_creds and bring your own. I tried to make the default behavior seamless for newbies.
