NuFi Crypto Wallet
Multi-chain Web3 wallet — Cardano, Solana and Ethereum in one app. Led design from zero to v1 beta.
The Problem Space
Entering the competitive Web3 wallet space required fast time-to-market without compromising UX — users were anxious managing multi-chain assets in one place.
Core Challenge: Launch a branded v1 wallet fast: simplify multi-chain comprehension and onboarding based on real feedback.
Solution & Architecture
Customized Material UI instead of building from scratch, set explicit network context everywhere, and deferred heavy onboarding — shipping v1 beta ahead of schedule.
Core Scenarios
The unified portfolio table consolidates balances across Cardano, Solana, Flow, and EVM chains with quick network filters, hide-zero toggles, and contextual asset actions. Sending funds is handled through a slide-out drawer featuring destination validation, MAX presets, and transparent network fee previews, while accounts per chain remain neatly organized with staked reward indicators and expandable asset trees.
Key Engineering & Design Trade-offs
Prevented irreversible cross-chain sending errors by making target chains visually unmistakable.
Ensured users confirmed gas fees and destination addresses before signing raw transactions.
Accelerated development by 3x to hit critical time-to-market window for token launch.
Transformation
Outcome & Measured Impact
Shipped v1 beta ahead of schedule with positive feedback on clarity and brand. Pragmatism beat pixels: adapting MUI freed time for real UX problems.
