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 the “largest infrastructure upgrade since its launch” within the next 2-3 weeks. This upgrade includes a complete overhaul of the trading engine and the introduction of the native stablecoin Polymarket USD. The upgrade will introduce a new CTF Exchange V2 smart contract system, optimizing matching logic and order structure to enhance matching efficiency and reduce 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. In terms of assets, Polymarket will launch the native stablecoin Polymarket USD, which is pegged 1:1 to USDC, to replace the previous cross-chain version USDC.e on Polygon, thereby improving 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 institutional and advanced users. Polymarket stated that the existing order book will be cleared during the upgrade, and the specific maintenance schedule will be announced one week in advance. This upgrade comes amid increasing competition in the prediction market, as the platform accelerates its efforts to enhance performance and user experience.
