Crosswire

Pre-trade resolution audit for cross-venue event markets.

Crosswire audits whether two prediction-market contracts on different venues (Polymarket, Kalshi) that look like the same bet will actually settle as the same bet — settlement scope, resolution source, timing, and void rules — before you put a hedge on. It returns an advisory verdict: SAFE / CAUTION / BLOCK, with the specific rule divergences it found. It never executes trades and never predicts outcomes.
