Trade arbitrage
on autopilot.
POLYARB is a trading engine that scans every Polymarket order book 24/7. Connect a wallet or deposit USDC — the bot hunts illiquid markets, stale resting orders, and resolution-lag mispricings while you sleep.

Three ways the bot finds edge.
No black-box claims. Every strategy is observable in the dashboard with the raw order-book context that triggered it.
YES + NO spread arbitrage
When the YES bid plus the NO bid exceeds $1.00 — accounting for taker fees — the engine takes both sides simultaneously to lock guaranteed profit.
Stale order detection
Resting limit orders become mispriced the instant news breaks. POLYARB watches every market's order book at WebSocket speed and hits stale levels before the maker cancels.
Resolution-lag mispricing
An event resolves but Polymarket hasn't settled yet. Prices drift toward $1.00 / $0.00 but rarely reach them — the engine front-runs the settlement.
Liquid markets have ~0 bps arb edge after fees — professional MMs close it instantly. POLYARB targets the long tail (markets under $50k volume) where edge persists.
Everything you'd build yourself, already shipped.
No spreadsheets. No homegrown Python scripts. No 3am wake-ups to fix a WebSocket. The boring infrastructure is solved.
Hybrid custody
Connect a wallet via EIP-712 or import a seed in your browser. Encrypted vault stays local. Deposit any asset, any chain.
Backtest live
Run any strategy against the real Polymarket order book with simulated fills. Prove an edge before funding the account.
Native desktop app
Tauri-built binaries for Windows, macOS, Linux. System tray, native notifications, deep links.
Telegram alerts
Every fill, every settled arb, every error — pushed to your phone. /pause and /resume the bot from chat.
Envelope-encrypted keys
Custodial private keys are AES-256-GCM encrypted with per-account DEKs, decrypted in-memory, zeroed after use.
Full audit trail
Every order, every cancel, every withdrawal — exportable as CSV. Tx hashes link straight to Polygonscan.
Live performance, recorded book.
The hero dashboard replays 30 minutes of real Polymarket order-book data on loop. The detector runs simulated trades against it. Numbers below come from a 30-day demo, not live customer accounts.
Stop watching the book.
Let POLYARB do it.
Free account. No card. No KYC for non-custodial. Production launch requires USDC on Polygon — bring your own.
