polymarket-copycat

A compact TypeScript stack that combines three pieces most copy-trading repos split across separate projects: a whale scanner (ranking wallets by realized P&L or win rate), a paper-trading engine that mirrors detected entries, and a dashboard for reviewing performance. At 45KB the codebase is small enough to read end-to-end in an afternoon, which is both a strength (auditable) and a weakness (likely shallow wallet-scoring heuristics rather than sophisticated attribution). The 'paper trading' framing is a good sign — the author is not pretending to have a proven edge. Real risks here are the classic copy-trading pitfalls: survivorship bias in whale selection, latency between observing a wallet's fill and mirroring it, and illiquidity on the copied side. No stars or forks yet, so the repo is essentially untested by the community. Good starting point for anyone building their own copy-trading pipeline or wanting a readable reference implementation in TS; not yet a deployable strategy.
