BitcoinOX

Context

Crypto without the fear of complexity

BitcoinOX sits between crypto and familiar banking: a hot wallet, cold storage and a card in one app. I led design as the core designer — from structure and navigation to specific flows, microcopy and edge cases.

Screens to MVP

40+ screens

Key flows

10 flows

Theme

Dark, from scratch

Ownership

Whole product UX

Goal

Combine wallet, storage and card into one clear product

Crypto scares people with complexity and the cost of mistakes. I had to connect a hot wallet, cold storage and a card so that a user with no crypto background wouldn’t get lost — without sacrificing control or security.

What I did

Designed the whole product — flows, settings, states

Sign-up and onboarding

Designed the registration flow with microcopy in an English fintech tone. Separately worked out the placement and wording of the promo/referral code field — so it wouldn’t get in the way of the main path, yet stayed visible to those who need it.

Settings architecture

Built the wallet settings — Base Unit, address format and other parameters — with a clear hierarchy and a single rule for editing.

Wallet, cold storage and card — in one UX

Studied competitors (all-in-one: hot and cold wallet plus a card) and built a single scenario where moving between storage and spending doesn’t break context and keeps a sense of control.

Outcome

A clear crypto product with predictable patterns

40 screens and 10 key flows for the MVP launch, a unified visual language and repeatable patterns: the editing rule, well-designed states, a dark theme.
