Reimagining an NFT marketplace with a minimal approach — MintVerse

For this project, I focused on simplifying the NFT experience through clean design and better usability.

I used Mobbin to study real product patterns like onboarding, navigation, and layouts. The goal wasn’t to copy designs, but to understand how great UX works and apply those principles in my own way.

Using Replit AI, I quickly turned these insights into a working product and iterated faster on design decisions like spacing, hierarchy, and clarity.

MintVerse is built from understanding, not imitation.
