Context
Phantom had established itself as the leading Solana wallet on desktop. The challenge was bringing that same experience to mobile — with full feature parity — while making crypto accessible to a new wave of users.

Case study snapshot
The short version before the full project story.
Key decision
Desktop-first crypto wallets don't translate well to mobile. Screen real estate is limited, transaction flows need to feel instant, and users expect native-level polish. We needed to ship a product that matched our desktop quality while feeling like it was designed for mobile from day one.
Role
I worked as Senior Product Designer on Phantom Mobile, shaping product decisions across Multi-platform.
Overview
Phantom had established itself as the leading Solana wallet on desktop. The challenge was bringing that same experience to mobile — with full feature parity — while making crypto accessible to a new wave of users.
Challenge
Desktop-first crypto wallets don't translate well to mobile. Screen real estate is limited, transaction flows need to feel instant, and users expect native-level polish. We needed to ship a product that matched our desktop quality while feeling like it was designed for mobile from day one.
Process
I worked closely with engineering and product to audit every desktop feature and determine how it should adapt to mobile. Key areas of focus included:
- Navigation architecture — Rethinking the information hierarchy for thumb-friendly interaction
- Transaction flows — Streamlining multi-step signing and approval flows for small screens
- Onboarding — Designing a frictionless setup experience for users new to crypto
Solution
We launched the Phantom iPhone app with full desktop feature parity, followed by Android. The app introduced a simplified navigation model, swipe-based interactions for common actions, and a redesigned onboarding flow that reduced setup time significantly.
Impact
The mobile launch coincided with Phantom's $109M Series B at a $1.2B valuation. The app quickly became one of the top-rated crypto wallets on both app stores, significantly expanding Phantom's user base beyond desktop-native crypto users.
