01 / The Challenge

One codebase,
every pocket

A consumer trading product lives or dies by distribution and feel. The bar for this MVP: reach users wherever they are — browser or Telegram — in their own language, with prices that move like a real market.

Two channels,
one build

An installable web PWA and a Telegram Mini App ship from the same codebase — one product, one release pipeline, two audiences.

Global from
day one

Three interface languages — English, Russian, Spanish — plus onboarding, social sharing and QR flows designed for viral, cross-border growth.

A live market
feel

Index prices and portfolio state stream in real time; trades are animated, earning is gamified with bonuses and progress — the product feels alive, not refreshed.
