There’s much more to share, but this gives you a good overview of our work. We also prepared extensive user testing, created libraries, and addressed other common elements in interface projects that aren’t detailed here. Thanks for following our journey and stay tunned for a new

Testing, learning, and improving the interface on the actual device revealed that the refresh rate was a major pain point. The screen supports 16 levels of gray; the more gray levels used, the longer the refresh time. To speed up the experience, we reduced color usage on key

Analyzing the existing Ledger Nano was our starting point. Ledger Stax retains 80% of the functionalities of previous devices. We identified pain points to improve user experience. Major issues included the number of tap and onboarding time. 🕵️♂️🔍 (3/11)

Understanding the product and its stakes. What is a hardware wallet? Why is it important? In short, a hardware wallet stores your private key (granting access to your crypto/NFTs) on an offline device, not on a third-party exchange (e.g., Binance, Coinbase), ensuring full control
