Gate News message, April 7, the prediction market platform Polymarket will carry out major upgrades to its trading system within the next few weeks. The core content includes launching Polymarket CTF Exchange V2, introducing a native stablecoin Polymarket USD, and optimizing the order book structure. The V2 version will rebuild the trading engine, optimize matching efficiency, reduce the operations required for order validation and matching, and lower Gas costs. The new order data structure will streamline the number of fields, improving overall execution efficiency. At the same time, V2 will introduce an upgraded central limit order book (CLOB), combining an off-chain order book with an on-chain execution mechanism. On the asset layer, Polymarket will launch Polymarket USD supported 1:1 by USDC, gradually replacing the cross-chain asset USDC.e currently in use. In addition, the platform will support the EIP-1271 standard, enabling smart contract wallets (such as multi-signature wallets) to participate directly in trading. During the upgrade period, the existing order book will be cleared and will briefly enter a maintenance window.
