Cassandra - Telegram Mini App
About the project and task
Cassandra is a closed application and Telegram Mini App that works with prediction markets (Polymarket, Preddy, Kalshi). The platform analyzes markets, tracks smart wallets, provides trading signals and copy-trading features.
The task was to design and implement a technological UI/UX in a dark aesthetic with blue and purple accents: to package analytics in a simple view, from the alert feed (Position, Volume, ROI) to filters and risk settings.
A system of screens has been developed: signal feed with quick purchase (Copy Trade), filters by category (Politics, Crypto, Sport) and risk (Low, Medium, High), account with push notifications and FAQ.
We owned the product end to end, covering UX/UI and development of a production-ready Telegram Mini App with its core flows and states.
