Polymarket releases Protocol V2 and will gradually transition to new markets starting November 2

Polymarket has released Protocol V2, its next-generation prediction market smart contract system, which refactors the original architecture built on the 2019 Gnosis Conditional Tokens Framework. The new version standardizes on a single ERC1155 position token contract, a single collateral asset (pUSD), and a unified exchange with integrated routing, while natively supporting multiple market types including Binary, Atomic Neg-risk, Incremental Neg-risk, and Combinatorial.
