About PolyArc — know before you bet
PolyArc puts one honest, glanceable grade on any Polymarket market page — and shows the facts behind it, in plain English, right where you bet.
It answers two questions:
• Is this market a trap? PolyArc flags manipulated volume (wash trading), ambiguous or disputable resolution rules, and thin liquidity or wide spreads you can't trade out of.
• Is the price fair? It compares the market price to the base rate — how similar markets actually resolved in the past — with an honest confidence interval and expected value after fees.
The grade is a simple traffic light:
🟢 GO — no traps detected, fairly priced. Your call.
🟡 BE CAREFUL — elevated risk in how the market is set up.
🔴 STOP — a serious integrity flag; a cheap price here is a red flag, not a deal.
⚪ NO DATA — we haven't analyzed this one yet, so we say so instead of guessing.
What PolyArc is NOT:
• Not a prediction of who wins.
• Not a betting tip — we never tell you what or how much to bet.
• Not a promise of safety. "GO" means "no traps detected and a fair price" — never "you'll win," and never "safe to bet."
Honest by design:
• Free — no ads, no venue kickbacks.
• Open source — the entire extension is public and inspectable at github.com/hcilabsdev/polyarc.
• We never call anyone a scammer; we report facts and let you decide.
• Default to "no edge." Most markets are an unremarkable green, and we'll tell you so.
Privacy:
We log anonymized usage — which markets are viewed, when, and the price at view, under a random per-install id — to measure whether the tool helps. No identity, no wallet, no bets, and your data is never sold. Full policy: https://polyarc.ai/privacy
PolyArc is an information tool, not financial, investment, or betting advice. Prediction-market participation is regulated and may be restricted where you live — check your local rules, and bet only what you can afford to lose.
