UI/UX Design for ChainCollector NFT Marketplace

ChainCollector is a Theta-based NFT marketplace focused on minting and selling NFTs tied to historically significant blockchain block numbers.

The founder needed to validate a novel NFT concept that combined blockchain history with collectability. There was no existing product, user experience, or brand. The challenge was to design a clear, trustworthy marketplace from scratch that could quickly explain a new idea, support minting and resale, and be simple enough to ship as an MVP without overcomplicating the experience.

As the sole UI/UX designer, I worked from 0-1 alongside the founder and a developer, owning the whole product and visual design for the MVP.

• End-to-end UI/UX design • User flows and marketplace architecture • NFT concept and visual design • Responsive UI layout (desktop and mobile) • Branding and visual identity • Minting and resale marketplace UX

A launch-ready MVP NFT marketplace with a clear, approachable user experience that explains the concept quickly and supports minting, browsing, and collecting NFTs. The final product balanced clarity with visual appeal, providing a solid foundation for validating the idea and iterating post-launch.
