If your app is on React, you can use react-open-app to enable deep links. If not, you can still borrow its implementation to do it yourself as it's MIT licensed. Also, Metamask Deeplinks is a good tool to get your deeplinks.

You have a constructor in your ERC20Basic contract that expects a totalSupply, you need to pass that value as a parameter when you're instantiating the class in your DEX contract. So you should have for example constructor() public { token = new ERC20Basic(1000000000); } depending on how you want to implement it. Hope this helps

I was able to compile it successfully via Remix using the compiler version 0.8.7. Most likely you might be using an older version that isn't able to compile the contract.
