The Challenge

A one-week design sprint leaves virtually no margin for misalignment or rework. The challenge was aligning the team and client rapidly, then translating that shared understanding into a testable prototype and high-fidelity identity, all validated with users before the sprint concluded.

    Design Approach

  • Design for trust at high-stakes moments

    Emphasized clear confirmations, fees, and state transitions so users felt in control when money moved.

  • Reduce onboarding drop-off

    Simplified setup and verification steps, making progress and requirements easier to understand.

  • Make state visible across sessions

    Improved status and history cues so users could quickly confirm what happened, and what to do next.

  • Keep the experience calm and fast

    Balanced speed with clarity through focused UI patterns that reduced cognitive load in everyday use.
