PANews reported on April 7th that the Polymarket team announced a full upgrade to its exchange architecture to CTF + CLOB v2 within the next 2-3 weeks, launching CTF Exchange V2 and a new collateral token, Polymarket USD. This upgrade will optimize order structure, matching efficiency, fee distribution, and support 1271 signatures and on-chain order attribution codes.

In addition, Polymarket will migrate from USDC.e to a new collateral token, Polymarket USD, which is 1:1 backed by USDC. Regular users can automatically wrap the tokens through the front-end interface, while API users need to manually do so using the wrap() function of the Collateral Onramp contract.

The new CLOB-Client SDK will support seamless switching from V1 to V2. Developers need to update to the latest version and re-sign orders on the migration date. During the migration, the existing order book will be cleared; the specific time will be notified one week in advance.
