Gate News update, April 6, on-chain prediction market platform Polymarket announced that it will carry out a major upgrade to its trading system in the next 2–3 weeks, including rebuilding the trading engine, launching a brand-new order book structure, and introducing the native stablecoin Polymarket USD. This upgrade’s core is the release of Polymarket CTF Exchange V2. This version will optimize matching efficiency, reduce the actions required for order validation and matching, and lower Gas costs. At the same time, the new order data structure will streamline the number of fields, improving overall execution efficiency. V2 will also 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, which is supported 1:1 by USDC, gradually replacing the cross-chain asset USDC.e currently in use, with the goal of reducing users’ security concerns about non-official bridged assets. In addition, the platform will support the EIP-1271 standard so that smart contract wallets (such as multisig wallets) can directly participate in trades. During the upgrade, the existing order books will be cleared and will briefly enter a maintenance window. Polymarket says this is the largest upgrade since it went live, coming at a time when platform users are growing and competition from multiple competing platforms is intensifying.
