PAL WALLET / CRYPTO WALLET · CROSS-PLATFORM PRODUCT DESIGN
A crypto wallet that makes buying, selling and swapping effortless
I inherited a stalled legacy wallet with incomplete exchange and security flows, inconsistent states, and a noisy visual language. As the sole product designer, I defined a calmer cross-platform experience built around task focus, trust, and consistent behavior across iOS, Android, and desktop.
Role
Sole product designer — research, UX, UI, interaction and full developer handoff for the entire wallet.
Product
Pal - a self-custody wallet to buy, sell, swap, send and request crypto. Be your own bank.
Platforms
One product, three platforms: native iOS, native Android and a downloadable desktop app.
Product judgment
Prioritized task clarity, trust, and cross-platform parity over feature density — then stayed involved through implementation and Design QA as constraints and feedback evolved.
Handoff
Delivered to development with specs and states, built for rollout to the international market.
Collaboration
Close work with the Product Manager, Head of Innovation (R&D) and CEO - their feedback shaped the design and the handoff.
02 / Challenge
Buying crypto felt intimidating - too much noise, too little focus
Pal replaced a legacy wallet that had stalled: Exchange was still a “Coming Soon” placeholder, Security shipped with lorem ipsum, transfers lived in a cramped modal, and red - the colour of loss - drove every primary button. History was a plain text log with no states. Newcomers met noise and dead ends. EPal had to make self-custody calm, obvious and safe - the same way on every device.

03 / RESEARCH & COMPETITIVE ANALYSIS
The legacy wallet and competitor patterns exposed the real product risk
I audited the legacy wallet screen by screen, then benchmarked the leading buy-and-sell products end to end — onboarding, funding, trading and security. I mapped what earned trust, what created friction and where users stalled. The findings set the direction: less on screen, one obvious next step, and identical behaviour across devices.
WHAT WORKED
Habits & frequency
Clear balances, a single primary action per screen and progressive disclosure kept the best apps approachable.
WHAT FAILED
Noise drives drop-off
Overloaded dashboards, hidden fees, unexplained states and forced device switches lost people mid-task.
THE OPPORTUNITY
Focus, everywhere
Remove the noise, keep one task in focus, and ship the exact same flow on iOS, Android and desktop.

04 / DESIGN GOALS & PRINCIPLES
One task in focus. Zero visual noise. Identical on every device.
05 / USER JOURNEY & INFORMATION ARCHITECTURE
A clear, logical path from first open to confident trading
The whole product is organised around one linear story. Each step reveals only what the user needs next, so attention always lands on the single most important action. The same five-step spine runs across mobile and desktop.
Onboard
Create or import a wallet in seconds.
Secure
Back up the seed phrase, set PIN & biometrics.
Fund
Buy crypto or receive to your address.
Trade
Swap, send or sell with one clear action.
Track
Follow balances, activity and prices.
06 / DESIGN SYSTEM & FOUNDATIONS
A small, disciplined system built to scale to 130+ screens
One primary blue carries actions and trust; green marks growth; red is reserved for loss and errors — a deliberate correction from the legacy wallet, where red drove every button. Inter, a restrained neutral scale, a shared token icon set and reusable components hold 130+ screens consistent.
07 / CROSS-PLATFORM PARITY
One product - identical on desktop and mobile
The downloadable desktop app and the native iOS and Android apps are the same product: the same five-step spine, the same components, the same language. Someone who starts on their phone can finish on desktop without relearning a thing. Every flow was designed in parity and handed off for all platforms.
08 / SECURITY & TRUST
Self-custody made safe - and simple to understand
Security is part of the flow, not a wall in front of it. Setup guides the user through backing up their keys and locking the wallet, in plain language, without ever slowing the core task.
24-word seed
A guided words-safety flow with export and confirmation.
PIN code
Create and confirm a PIN to open the wallet.
Face / Touch ID
Biometric unlock on supported devices.
Be your own bank
Private keys stay with the user - never shared.
09 / COLLABORATION & HANDOFF
Close collaboration with leadership - then a build-ready handoff
Although I was the only designer, I worked hand in hand with the Product Manager, the Head of the Innovation R&D department and the CEO. Their corrections, advice and comments were folded into the design as it evolved — and carried through into the specifications I handed to the development team for the international rollout.
WORKED CLOSELY WITH
Product Manager
Aligned scope, priorities and requirements — my day-to-day partner across the project.
Head of Innovation (R&D)
Reviewed each flow against the innovation roadmap and helped shape product direction.
CEO
Set the vision and business goals; feedback that steered key decisions before handoff.
10 / DESIGN QA & QUALITY
Design isn’t done when the mockup is - it’s done when the build matches
Across 130+ screens and three platforms, consistency is the first thing to drift: a ticker, a unit, an empty state, a control that behaves differently on mobile. I treated quality as part of the design work rather than a phase after it — every screen shipped with its states defined, and I reviewed the implemented build against the spec before it was called done.
Specs & states
Each screen documented with empty, loading, error and success states, plus the copy for each.
Consistency passes
Recurring sweeps over tickers, units, labels and icons to catch drift across platforms.
Build review
I checked implemented screens against the designs and logged spacing, state and copy defects.
Definition of done
Done meant design, states, copy and the shipped build all agreed — not just a tidy frame.
11 / OUTCOME
A stalled legacy wallet became a coherent cross-platform product foundation
The result is a calm, self-custody wallet where buying, selling and swapping take a few clear taps — identical on iOS, Android and desktop. It was delivered to development as a complete, build-ready product for rollout to the international market.
Cross-platform parity
One identical experience across mobile and desktop.
Research-led simplicity
Every screen reduced to one clear task - no visual noise.
Build-ready handoff
Specs, states and components delivered for global launch.
