Deploy and Host Polymarket Bot V2 on Railway

Polymarket Bot V2 is a lightweight, TypeScript copy‑trading bot that mirrors trades from selected Polymarket traders while enforcing spend limits and optional auto‑cashout (redeem) after resolution. It runs continuously, polls Polymarket activity, and executes trades with clear risk controls and a minimal configuration surface.

About Hosting Polymarket Bot V2

Hosting Polymarket Bot V2 on Railway means running a long‑lived Node.js process with a small local state file. You’ll configure environment variables for the wallet, traders to copy, and risk limits. If you enable auto‑redeem, you’ll also provide a Polygon RPC URL and Polymarket Builder credentials. Railway handles deployment, restarts, and logs, while you attach a volume to persist state across restarts. Once deployed, the bot keeps polling and mirroring trades automatically.

Common Use Cases

Copy‑trade a single high‑signal Polymarket trader with hard spend limits
Mirror multiple traders at a fixed percentage to diversify exposure
Run an always‑on bot that auto‑redeems resolved markets

Dependencies for Polymarket Bot V2 Hosting

Node.js 18+ (recommended 22)
A Polymarket account (Magic email login supported)

Deployment Dependencies

Polymarket Builder Profile (for auto‑redeem) — https://polymarket.com/settings?tab=builder
Magic private key export — https://reveal.magic.link/polymarket
