Polymarket Head of Protocol Rajath Alex announced Protocol V2, which replaces its legacy 2019 Gnosis CTF foundation. V2 unifies the system around a single ERC-1155 position contract, pUSD collateral, and a consolidated exchange and router, supporting binary, neg-risk, and combinatorial markets. It integrates a multi-oracle aggregator (supporting UMA and Chainlink) and embeds cross-chain bridging. Canary markets will be tested from October 5 to 30 before the planned November 2 rollout.
