1. Polymarket Launches Protocol V2 with Full Contract Overhaul, Mainnet Switch on Nov 2 link Polymarket Protocol lead Rajath Alex announced the launch of Polymarket Protocol V2, which fully rebuilds the Gnosis Conditional Tokens Framework (CTF) used since 2019. The V2 architecture unifies position token contracts into a single ERC-1155 standard, uses pUSD exclusively as collateral, and provides one unified exchange and router for all market types. Its modular design natively supports binary, atomic negative-risk, incremental negative-risk and combinatorial markets. It also introduces OracleAggregator enabling integration with multiple oracle sources including UMA and Chainlink, plus a native cross-chain bridging module.
