Web3 Product Design for StreamEx

Kenneth Lopez

Product Design that fueled a Coinbase partnership

As Founding Designer at Streamex, I helped turn an early vision into a product built to scale. I led UX strategy and designed the core experience for Streamex, a crypto platform bringing real-world assets on-chain. This work included the investor demo that helped secure a Coinbase partnership and laid the product foundation for a Nasdaq debut.

The Problem

StreamEx was building a crypto platform to tokenize real-world assets, but they were pre-product with no design foundation. Their challenge wasn’t just visual polish, it was defining how an RWA exchange should work at a UX level: how users discover assets, compare yields, onboard capital, and trust the system. They needed a product experience that could speak to both crypto-native users and institutional partners while supporting a fast-moving go-to-market.

My Role

I joined as the Founding Designer and led the end-to-end product design. This involved:
Designing the full investor and user-facing platform, including asset discovery, order execution, and portfolio management flows
Working closely with the founders and engineers to shape features around regulatory, custody, and compliance constraints
Building a modular design system from day one to allow rapid iteration without fragmenting the UI
Creating a high-impact investor demo that made the vision tangible and credible to partners like Coinbase and early institutional backers
Designing for edge cases in settlement states, wallet connection issues, and fiat onramps to reduce user drop-off
Everything was optimized for speed, clarity, and scale from zero to investor-ready in weeks.

The Outcome

Helping secure a partnership with Coinbase and positioning the company for its upcoming Nasdaq debut. The investor demo turned abstract vision into tangible product, accelerating trust with stakeholders and enabling high-stakes conversations with institutions. Beyond the pitch, the platform UX laid a scalable foundation for onboarding both crypto-native and traditional finance users into the RWA space.
