Open-source pm-copy-trader project

I open-sourced pm-copy-trader for developers in Open-source developer tools. This post walks through what it does, how the pieces fit together, and how to run it locally.

Live demo / site: https://polymarket.com/@pmtraderadam?via=pmtraderadam

Why I built this

Explore pm copy trader patterns in open-source developer tools
Fork the repo as a starter template for your own project
Contribute features, docs, or tests via pull requests

Most tutorials stop at a smart contract or a UI mockup. I wanted a complete vertical slice — wallet flow, on-chain logic, backend state, and a responsive frontend — so you can study or fork a production-shaped codebase.

What it does

Late-window favorite snipe on BTC, ETH, SOL, XRP 5m Up/Down markets
Live Polymarket price polling (Gamma + CLOB APIs)
Simulated entry/exit with P/L tracking
One position per asset per window (max 4 concurrent)
Tunable constants in src/index.ts
Runtime logs to console and logs.txt
Automated copy-trading strategy execution
Tunable constants in src/index.ts

Architecture at a glance

Application layer — TypeScript backend/frontend tying on-chain and off-chain flows
Feature — Late-window favorite snipe on BTC, ETH, SOL, XRP 5m Up/Down markets
Feature — Live Polymarket price polling (Gamma + CLOB APIs)
Feature — Simulated entry/exit with P/L tracking

User Wallet  →  On-chain Program  →  VRF / Settlement
                    ↓
              Backend (API + WebSockets)  →  MongoDB / state
                    ↓
                 Frontend UI (real-time)

Adjust the diagram to match your repo layout if components differ.
