Challenge

The best Polymarket traders are public, but copying them by hand is impossible — positions open and close around the clock, sizing has to scale to each user's bankroll, and one bad whale can blow up an account. Catching the edge means ranking thousands of wallets daily, mirroring their trades in real time, and enforcing risk limits on every fill.

02

Solution

PolyHuntr ingests 8,000+ Polymarket markets every ten minutes over the Gamma, CLOB, and RTDS WebSocket feeds, then scores every public wallet on Sharpe, drawdown, and freshness. The top 100 are frozen at midnight UTC into a daily leaderboard users can copy with one click. A copy executor mirrors each tracked wallet's trades using one of five sizing modes — mirror, fixed, proportional, capped, or Kelly — with per-wallet overrides and account-wide risk caps. A paper backtester lets users validate a strategy before risking capital, and on-demand AI deep analysis explains any wallet or market when a user clicks in.
