Polymarket Rolls Out V2 Protocol Upgrade Polymarket has started testing Protocol V2 with production canary markets, replacing its 2019 Gnosis-based framework with a redesigned architecture. The upgrade uses a single ERC-1155 positions contract, pUSD as collateral, dedicated exchanges for four market types and a new router. V2 initially supports Binary, Atomic Neg-risk, Incremental Neg-risk and Combinatorial markets, with a new OracleAggregator connecting to UMA, Chainlink and other data sources. Canary markets will run through October 30, with Polymarket tentatively targeting November 2 for V2 to handle new markets.
