Polymarket overhauls smart contracts with new Protocol V2 rollout

What happened: Polymarket began rolling out Protocol V2 on Monday, a new smart contract system supporting different market types through a single exchange. Testing runs on limited live markets through Oct. 30, with a tentative Nov. 2 target for new markets. Key numbers: Testing through Oct. 30; tentative Nov. Why it matters: The overhaul replaces 2019-era code and adds upgradeable contracts plus OracleAggregator, which connects to oracles including UMA and Chainlink. Existing positions stay on the current system and are not converted to V2.
