 ## Challenge
 
 Fork this repo and build out more features! This is minimalistic on purpose.
+
+We purposefully built this app to be minimalistic so that you can get some software development practice in fixing our bugs! 🪲
+
+Here are a few challenge suggestions:
+
+1. Add Wallet integration so that any user that connects their wallet can check their ERC-20 token balance
+2. There is no indication of a request in progress... that's bad UX! Do you think you can add some sort of indication of loading?
+3. Add some styling! 🎨
+4. The token balances can sometimes be a little long and break the outline of the page... can you fix that? 🔧
+5. There is no error-checking for wrongly formed requests, or really any error checking of any kind... can you add some in?
+6. The images and grid display could look better... anything you can do about that?
+7. There are ways to make this app faster... can you implement some of them? How can the query be made _even_ quicker?
+8. Can you add ENS support for inputs?
+9. Completely open-ended!! Use this as the base for your next hackathon project, dream company or personal expedition :)
