FINTECH MVP NDA

Stealth Dollar Wallet

I’m building a consumer fintech product — a mobile wallet for simple digital dollar transfers. The product is in active development, so some details and branding are intentionally hidden. The goal is to remove crypto complexity and make Send / Receive feel calm and familiar, similar to Apple Cash.

Problem

Most crypto wallets are designed for people who already understand the space. As a result, they’re overloaded with networks, tokens, gas fees, and intimidating terminology. For mainstream users, this creates real risk: choose the wrong network, misunderstand a fee, send to the wrong place — and money can be lost. At the same time, the core need is simple: people want to send and receive dollars quickly, without having to learn how the underlying tech works.

Goals

This project focuses on reducing the product to two core actions: sending and receiving. I intentionally removed everything that doesn’t strengthen the MVP — no swaps, NFTs, or dApp features. The priorities were iOS-native behavior, clear copy, full edge-case coverage, and a security model that users can understand. I also kept App Store constraints in mind and avoided any messaging that could create misleading expectations.

My role

I worked as product designer: I defined the concept and positioning, designed the UX architecture, built the key flows and states, created the iOS-style UI, and wrote the product copy and tone of voice. A major part of the work was designing edge cases and ensuring the app explains issues clearly without causing panic.

Key decisions

For MVP, QR is “address-only.” The QR code contains only the wallet address, and the sender enters the amount. This keeps the experience easy to explain, reduces mistakes, and speeds up launch. The second key decision is fee abstraction through Energy. Users see a simple model — “1 Energy = 1 transfer” — while network complexity stays in the background to preserve a true fintech feel.

Security

Security is embedded into the UX. Critical actions are protected with Face ID, wallet locked states are supported, and the recovery phrase is explained clearly and calmly. The product does not store or see the recovery phrase and cannot access user funds. The experience sets the right expectation: users are in control, and restoring access is only possible with the saved phrase.

States

I designed full state coverage so the app behaves predictably in real-world scenarios. The product handles invalid addresses, unsupported QR codes, insufficient balance, insufficient Energy, pending or canceled transactions, and activity that wasn’t initiated from the current device. In every case, the goal is the same: explain what’s happening and provide the next step.
