BlockBeats report: On April 7, the on-chain prediction market platform Polymarket announced it will undergo its largest infrastructure upgrade since launch over the next 2–3 weeks, including a complete overhaul of its trading engine and the launch of its native stablecoin, Polymarket USD.
This upgrade will introduce the new CTF Exchange V2 smart contract system, optimizing matching logic and order structure to improve matching efficiency and reduce Gas costs. Additionally, the platform will upgrade its Central Limit Order Book (CLOB) to a hybrid model combining off-chain order matching with on-chain settlement.
At the asset level, Polymarket will launch Polymarket USD, a native stablecoin pegged 1:1 to USDC, to replace the previously used cross-chain version USDC.e on Polygon, enhancing asset security and consistency.
In addition, the platform will support the EIP-1271 standard, enabling multisignature wallets (such as Safe) to participate directly in transactions, further expanding use cases for institutional and advanced users.
Polymarket states that the existing order book will be cleared during the upgrade, and the specific maintenance window will be announced one week in advance. This upgrade comes amid intensifying competition in the prediction market space, as the platform accelerates improvements to performance and user experience.
