Project Summary

Software Mansion provided ongoing React Native engineering to build a mobile Ethereum wallet (initially on iOS, with Android work underway) for a small startup. The vendor delivered complex UI work—navigation, animations and gesture handling—based on Sketch and Figma designs and helped expand React Native libraries where needed. The app is live on the App Store and has received positive user feedback for its look and interactivity. The engagement remains active with continuous feature development.

Key Challenges

  • Small internal team lacked capacity to build features at the needed pace
  • Need to reach product-market fit with intuitive, consumer-facing decentralized finance UX
  • Required advanced React Native expertise to implement complex navigation, animations, and gestures
  • Managing scope and scheduling to avoid engineering backlog as the team scaled

Project Deliverables

  • Mobile Ethereum wallet iOS app
  • React Native codebase with custom navigation, animations, and gesture handling
  • Ongoing engineering support and project management
  • Contributions to open-source React Native libraries

Project Solution

Software Mansion engaged in a continuous engineering partnership, supplying React Native engineers and a project manager to implement features from Sketch and Figma designs. They built and iterated the iOS app (and began Android support), implemented complex navigation, animations and gesture handling, took ownership of feature implementation decisions, and contributed enhancements upstream to React Native open-source libraries. Communication used Slack, Linear for task tracking, and weekly syncs to manage priorities.

Project Outcome

  • Shipped product live on the App Store
  • Overcame navigation and gesture handling challenges by expanding React Native libraries
  • Received positive user feedback on the app's look, feel, and interactive experiences
  • Continued feature development through an ongoing engagement
