Make markets,
not mistakes.
A professional desktop cockpit for providing liquidity on Polymarket US. Reward-aware quoting, institutional risk controls, and a kill switch you can trust — all running local-first on your own machine.
Code-signed & notarized for macOS and Windows.
Built for liquidity
Everything a market maker needs, nothing they don't.
A focused toolkit for quoting, hedging, and surviving — engineered for speed, control, and parity between sim and live.
Live market data
Real-time order book, depth, and time & sales streamed over websocket — no polling, no lag between you and the tape.
Reward-aware quoter
Avellaneda–Stoikov inventory-skew quoting tuned to target liquidity rewards. Dry-run by default until you arm it.
Hard risk controls
Pre-trade checks, self-match prevention, position & exposure limits, and reject-storm auto-disarm that pulls quotes fast.
Kill switch & dead-man
One-click cancel-all, plus a dead-man heartbeat that withdraws every quote the moment your terminal goes dark.
Sim & backtest
A deterministic matching engine and historical replay that reuse the live code paths — so your sim matches production.
Secure by design
File-based encrypted credentials and an optional SQLCipher database. Your keys never leave your machine.
How it works
From keys to quotes in four moves.
A workflow designed to keep you in dry-run until you're certain — then get out of your way.

The Quoter
Quote with an edge. Manage the risk.
An Avellaneda–Stoikov core skews your quotes around live inventory and volatility, biasing toward the rewards you actually want to capture. Tune every parameter, validate in dry-run, and arm only when you're ready.
- Inventory-skew quoting
- Reward-target optimization
- Dry-run parity with live
The Risk Engine
Guardrails that fire before you do.
Every order passes pre-trade checks first: position and exposure limits, self-match prevention, and a reject-storm circuit breaker that auto-disarms. A dead-man heartbeat pulls all quotes the instant you lose connectivity.
- Pre-trade risk checks
- Reject-storm auto-disarm
- Dead-man heartbeat + kill switch
The Cockpit
Your whole book, on one pane of glass.
A dense, terminal-grade interface that puts the order book, depth, blotter, P&L, and risk in front of you at a glance. Keyboard-first, dark by default, and tuned for hours of focused screen time.
