Polymarket Begins Protocol V2 Rollout With pUSD Collateral and ERC-1155 Positions

Polymarket began production canary testing of Protocol V2 on October 5, putting its new trading architecture into a limited live trial ahead of a tentative November 2 switch for new markets. The test is scheduled to run through October 30, according to The Block . The overhaul changes two elements of the prediction-market platform’s underlying stack: it unifies market positions under ERC-1155 and uses pUSD as collateral for the new architecture. The deployment is staged, not an announced full-platform migration, and the proposed November change would apply only to newly created markets.
