Z3US – A crypto wallet built on the Radix network.
Crypto wallets are notoriously clunky. We saw an opportunity to build something different—a wallet that prioritizes user experience over flashy features, performance over marketing gimmicks.
In a short time, Z3US gained over 40,000 users, with no paid promotion. Users were organically sharing it, reviewing it, and making YouTube videos about how much they loved it—all without us asking.
User-First Design We started with the basics: How do people actually use crypto wallets? What frustrates them? What would make their experience genuinely better?
Performance Obsessed Every interaction needed to feel instant. No loading spinners, no lag, no excuses. We built with performance as a core constraint.
Build It Right Rather than rushing to market, we took time to craft every detail—from micro-interactions to the overall information architecture.
Core Wallet Experience Send, receive, and stake functionality that just works. Clean interfaces that don't overwhelm, with all the power users need under the hood.
Portfolio Management Real-time balance tracking, transaction history, and asset management that gives users confidence and control.
Staking Made Simple We turned complex staking processes into intuitive experiences, making DeFi accessible to everyday users.
Multi-Asset Support Comprehensive token support with beautiful asset cards and seamless switching between different cryptocurrencies.
“Love your work - if you want to see an awesome wallet experience already on Radix, definitely check out Z3US.”
Legible Code: We built Z3US to be maintainable and scalable, with clean architecture that makes feature development fast and reliable.
Tested Under Pressure: Every screen was tested to feel quick, legible, and sharp under pressure. No edge cases, no broken flows.
Performance First: From token lists to analytics, from staking to send flows—every interaction was optimized for speed and clarity.
We had two acquisition offers. We turned both down—because we believed in the technology, and we wanted the wallet to remain open source.
But crypto moves fast—and not always forward. As interest in Radix faded and the token value dropped below the top 500, the momentum around the network slowed. Z3US remained solid, but the ecosystem around it didn’t keep up.
It was a big bet that taught us a lot about building in emerging markets. Most importantly, it showed what a small, focused team can accomplish when they believe in the product and execute with precision.
