The Real Challenge
Creating a secure and frictionless experience for first-time and advanced crypto users.
Pain PointsGoalsTG Demographics1.
Onboarding
Began with research on competitor apps and user confusion around crypto jargon. I wireframed four versions before realizing less is more. Added microcopy and illustrations that say, ‘Relax, we got you.’
2.
ID Verification
Mapped out a secure flow that felt trustworthy but not intimidating. Prototyped badge animations to assure users their data was safe—finally landed on a clean, status-based progression UI.
3.
Sign Up / Login
Explored email/OTP/social-login combos. Settled on a minimal form UI with light interactions. Did usability testing—my uncle could sign in without calling me.
4.
App Pin & Face ID
Prioritized a secure but smooth setup flow. Integrated native biometric prompts and added subtle animations to make it feel polished.
5.
Home
Iterated the dashboard layout six times. The challenge? Showing enough info without looking like a trading terminal. Focused on clarity, quick-glance stats, and subtle highlights for coin movements.
6.
Inbox
Designed an intuitive space for alerts and support messages. Even error notifications got a calming tone.
7.
Profile Page
Explored modular settings cards. Ran quick preference tests for layout. Balanced personality with simplicity.
8.
Deposit
Built a guided experience with real-time feedback. Added loading states and confirmation animations—because no one likes watching money ‘go somewhere.’
9.
Detailed Coin Page
Balanced data-rich visuals with digestible layouts. Visualized trends via clean graphs, color-coded indicators, and tooltips. (Yes, I axed three tabs after discovering users hated them.)
10.
Buying a Coin
Tested CTA placements, redesigned the input flow for speed and confidence, and added visual checks before confirming. A little panic-testing went a long way.
11.
Selling a Coin
Mirrored the buy flow to leverage muscle memory. Added a cheeky success animation—one user said it ‘felt like a high five.’
