- The upgrade consolidates markets into a single ERC-1155 position contract, adopts pUSD as collateral, and utilizes a multi-oracle aggregator featuring UMA and Chainlink.
- Following formal verification by Certora and extensive auditing, testing will proceed via canary markets running from October 5 to October 30.
Polymarket Unveils Protocol V2 Architecture Upgrade
Decentralized prediction market platform Polymarket has announced the impending rollout of Protocol V2, marking a major overhaul of its core infrastructure. The full mainnet switchover is officially set to take place on November 2, replacing the outdated Gnosis Conditional Token Framework (CTF) foundation that has powered the platform since 2019. Details of the system transition were reported by CryptoTwitter commentator @WuBlockchain, spotlighting structural advancements intended to modernize the exchange’s operational capabilities.
The transition to Protocol V2 is engineered to significantly streamline operations across the platform by consolidating various market types. At the core of the technical architecture is the implementation of a single unified ERC-1155 position contract, moving away from fragmented token setups. In addition, the protocol will adopt pUSD as collateral to standardize liquidity and trading across its prediction markets.
Multi-Oracle Settlement and Rigorous Verification Phase
In a notable shift toward enhanced security and settlement reliability, Protocol V2 introduces a multi-oracle aggregator framework. The new model integrates both UMA and Chainlink to process outcomes and market resolutions. To guarantee protocol safety ahead of deployment, the underlying smart contracts have been formally verified by blockchain security firm Certora and subjected to heavy security audits.
Before executing the final mainnet transition in November, Polymarket will conduct controlled stress tests in a live environment. The rollout schedule includes a dedicated canary testing window operating from October 5 to October 30. These canary markets will enable real-world evaluation of the consolidated contracts, collateral performance, and oracle integrations under live conditions.
Why This Matters
Currently, Polymarket is recording a lull in trading activity, registering a 24-hour volume of $0. This pause reflects a cautious sentiment across the ecosystem as market participants await the deployment of the new infrastructure amidst broader volatile market conditions. The shift to a modular design and native support for cross-chain bridging under Protocol V2 represents a critical turning point for the platform. By resolving legacy limitations inherited from the 2019 Gnosis CTF setup and unifying collateral under pUSD, the architectural overhaul is structured to attract deeper liquidity and expand user onboarding once fully active.
