Polymarket Announces Major Upgrade: Overhauling Matching Engine and Launching Native Stablecoin

On April 7, the on-chain prediction market platform Polymarket announced that it will undergo its “largest infrastructure upgrade since launch” within the next 2-3 weeks, including a comprehensive overhaul of its matching engine and the introduction of a native stablecoin, Polymarket USD. This upgrade will introduce a new CTF Exchange V2 smart contract system, optimizing matching logic and order structure, improving matching efficiency, and reducing gas costs. Additionally, the platform will upgrade its Central Limit Order Book (CLOB) to a hybrid model of off-chain order matching and on-chain settlement. On the asset side, Polymarket will launch the native stablecoin Polymarket USD, pegged 1:1 to USDC, to replace the previous cross-chain version USDC.e on Polygon, enhancing asset security and consistency. Furthermore, the platform will support the EIP-1271 standard, allowing multi-signature wallets (such as Safe) to participate directly in trading, further expanding use cases for institutions and advanced users. Polymarket stated that the existing order book will be cleared during the upgrade, and specific maintenance times will be announced one week in advance. This upgrade comes at a time of intensified competition in the prediction market sector, as the platform accelerates its performance and user experience enhancements.
