Product
Trillions is a crypto bank with a mobile app. It supports fiat and crypto accounts, transfers, currency exchange, and investments.
Trillions
From a mobile product to a full web platform
The MVP is in active development. The public launch of the mobile and web product is planned for Fall 2026.
CONTEXT
Role
Designing user flows and the full web platform.
Team
The PM owned the brief and scope; developers built the product using the design system and tokens.
Scope
The web platform and design system were built from scratch.
My responsibility
Product architecture, user flows, UX/UI, prototyping, design system, and development support.
Outside my responsibility
Post-launch analytics, backend, and marketing strategy.
PROBLEM
Trillions existed only as a mobile app. The business goal was to move to the web: reach corporate clients, older users, and people who prefer managing finances on desktop.
The problem was not simply “moving screens”: the mobile flow was designed for a small screen, linear and step by step. A transfer flow took 3-4 screens. On the web, this would create unnecessary transitions and make the product feel unfinished. An additional challenge was the dual domain: fiat and crypto assets have fundamentally different logic, but need one shared interface.
PRODUCT GOALS AND SUCCESS CRITERIA
Launch the web MVP and validate demand for a web channel among B2C and B2B users.
POST-LAUNCH METRICS
01Activation RateShare of users who complete the first target action in the web version.
02Task Completion RateShare of successfully completed core scenarios.
03RetentionWhether users return to the web product after their first session.
04Drop-off RateShare of users who leave a core scenario before completion.
05CSATEase-of-use rating after completing an operation.
HYPOTHESIS
Users working with large amounts or recurring transfers will prefer the web version because it gives more context and fewer steps. Analytics, reports, and a trading terminal are also easier to use on the web.
01
Reworking flows for the web context
Instead of moving mobile steps as-is, I redesigned the action logic for a larger screen. On mobile, a transfer to an external wallet takes 3+ sequential screens: account selection, address, amount, confirmation. On web, everything is combined into one screen: From, Send to, Amount, and the final amount are visible at once.
02
Switching the Fiat / Crypto context
I designed a single switching pattern between fiat and crypto modes. The Fiat/Crypto tab changes not only the data, but also block logic, charts, and account structure, while navigation and overall layout stay stable.
03
Design system
The design system provided a shared set of components and tokens for the mobile and web teams.
FEATURES
2FA authentication, fiat and crypto account management, transaction history, analytics, basic transfers and currency exchange, reports, support, and profile.

TAKEAWAYS
What I would do differently
At the start, I would run more formal research with potential web users, especially the B2B segment.
