The currently supported protocols are: Hive, Hive Engine and Splinterlands. I'm planning to add EVM soonish (Base, BSC, etc.).

For Hive Engine only tokens are currently supported and they need to be defined so they are shown even when balance are 0, otherwise if balance is > 0 they should also be shown if not defined within the app.

So TL;DR: yes.

If you could provide me with a list of tokens regarding dcrops that would be highly appreciated!
