Context
On Polymarket, a handful of traders show gains of several million dollars. PolyTrack watches their wallets, records every trade and makes them searchable in a dashboard, with a Discord alert for each new position.
Role
Full design and development: monitoring bot, API, database, dashboard and deployment on my server.
Architecture

Challenges
Polymarket blocks automated trading from Europe: I tested several network setups (OpenVPN, SOCKS5 proxy, proxychains, Cloudflare Warp) before concluding that automatic execution requires a US-hosted server. On the data side: a missing UNIQUE constraint on the transaction hash that broke upserts, wrongly typed UUIDs, and a CORS error when the domain changed.
Outcome
A live service: the bot runs continuously under PM2, trades are stored in PostgreSQL, and the dashboard is served on its own HTTPS subdomain.
Highlights
- Continuous monitoring of top traders' wallets
- Discord alert for every new trade
- Bot + API under PM2, frontend in a Docker container
