Polymarket BTC 5m Jev trader
Terminal agent for Polymarket's BTC Up or Down five-minute markets. Roughly every five seconds it asks Jev whether BTC finishes UP or DOWN versus the window open, then abstains or buys once and holds to resolution. Defaults to dry-run; live orders are opt-in.

About this project
A terminal agent for Polymarket’s BTC Up or Down 5-minute markets. It watches the live 5m window, asks TypeSafe Jev whether BTC finishes UP or DOWN vs the window open, and either abstains or buys once and holds to resolution. Default mode is dry-run (no real orders). Live trading is optional. For live trading only: a Polygon wallet that already works on Polymarket (connected, funded with USDC.e, able to trade in the browser). This project does not set allowances or deposits for you.
Quoted from the project's README. Read the full README.

Highlights
- Asks Jev for side plus confidence each tick and enters only when confidence is above 0.90
- Also requires ask at most 0.70, edge at least 0.10 and 90+ seconds left; otherwise it waits
- Dry-run by default; live mode posts fill-or-kill CLOB orders only when LIVE_TRADING=1
- Offline fixture mode with --stub-judge runs without a TypeSafe key for testing
- Ink TUI plus npm run once for a single tick as JSON; thresholds configured through .env
Watch out
No license file, so the code is all rights reserved by default. Experimental software and not financial advice; live trading needs a funded Polygon wallet and can lose money.
Questions about this entry
Short answers drawn from the linked project or page.
No. The default mode is dry-run with no real orders. Live trading requires setting LIVE_TRADING=1 plus wallet credentials, and it buys at most once per five-minute window and holds to resolution.
Yes, for offline testing: POLYMARKET_SOURCE=fixture with --stub-judge runs on fixture data with a stub judge, while real decisions need TYPESAFE_API_KEY in .env.
Clone the repository, copy `.env.example` to `.env`, set `TYPESAFE_API_KEY`, and run `npm install`. `npm run watch` opens an Ink TUI showing DRY-RUN and `npm run once` performs a single JSON tick; both need Node.js 20 or newer.
Live mode sets `LIVE_TRADING=1`, `WALLET_PVK` with the wallet private key, `POLYMARKET_FUNDER` for the deposit or proxy address, `SIGNATURE_TYPE=3` for the POLY_1271 deposit wallet, `POLYMARKET_SOURCE=live`, and `BET_USD` for the maximum per entry.
On each tick it asks Jev for side, confidence and probabilities, then applies policy in code: it buys once when confidence is strictly above the 0.90 ACT_THRESHOLD and the edge is acceptable, and waits when confidence is at or below 0.90, the ask exceeds MAX_ASK, or fewer than 90 seconds remain.
Polymarket's rules decide, not share odds: the README says winners are determined by Chainlink BTC TWAP versus the price to beat. Jev only supplies a side and confidence, which code compares against the ask and the edge threshold.
It calls itself experimental software and not financial advice, and warns that you can lose money. It is not affiliated with Polymarket or TypeSafe beyond using their APIs and SDKs, and in live mode it never sets allowances or deposits for you.

OpenClaw plugin and CLI that turn a plain-language --when/--not-when condition into a scheduled trigger script. Each tick sends one Noul through OpenClaw's decisionModel and only wakes the conversation model when the condition reaches 0.7 or above; a 76-tick benchmark reports 75 correct judgments and 0 false wake-ups.

Original write-ups on what this entry is for.
The request shape barely changes across surfaces; the surrounding contract does. When to call the API directly and when a gateway, a Worker binding, or a router entry earns its extra hop.
