01 · Overview

What is Matchr?

Matchr documents a cross-venue workflow for finding equivalent prediction markets, comparing prices, and routing orders across Polymarket and other venues. Its API also exposes matched-market data for builders. This is more than a comparison dashboard because the provider describes execution and smart routing, but wallet permissions, supported venues, fees and live behavior still require access checks; spread and profit claims are not independently verified.
