Polymarket Rebuilds Its Core Smart Contracts With Protocol V2, Targets Nov. 2 Switchover

On Monday, Protocol Rajath Alex introduced Polymarket Protocol V2, a comprehensive rebuild of the platform's core smart contracts designed to replace the system used since launch.
The platform was built on the Conditional Tokens Framework, code Gnosis released in 2019, which Alex noted "Polymarket currently runs on smart contracts that were never designed for what it became."
V2 consolidates the architecture into a single ERC-1155 contract and one router, with code audited by Certora, Quantstamp, and Zellic alongside a $5 million bug bounty.
For users, "No technical migration is required," according to Polymarket, as existing positions remain under the old framework while new markets transition to V2 on Nov. 2.
A new OracleAggregator handles resolution and connects to UMA and Chainlink, while the system supports upgrades through governance, positioning V2 as the foundation for future features like scalar resolution.
