Polymarket Neg-Risk Exchange

polymarket-neg-risk-exchange-v1-polygon

Matches orders for multi-outcome Polymarket markets. Filled orders use neg-risk outcome tokens, then resolution flows through the Neg-Risk Adapter before final CTF-style settlement.

Trader order → Neg-Risk Exchange → Neg-Risk Adapter → UMA Adapter → Final payout

Shares the same trading ABI as the CTF Exchange; the difference is the market path.

Market type	Multi-outcome / mutually exclusive markets
Token path	Neg-risk outcome tokens
Resolution path	Neg-Risk Adapter + UMA Adapter
Compare with	Polymarket CTF Exchange
