Polymarket is overhauling its trading experience with a new V2 exchange contract and private label stablecoin.
What's the Scoop?
- Full Overhaul: Polymarket is upgrading its entire trading stack over the next 2 to 3 weeks, deploying a new "CTF Exchange" contract. This change will optimize the order structure and matching process, support ERC-1271 signatures, include builder codes for onchain order attribution, and better fee collection and distribution. The end result will be lower gas fees and faster transaction speeds.
- New Stablecoin: Polymarket will migrate from USDC.e to a new Collateral Token (Polymarket USD), backed 1:1 by USDC. For most users, this transition is seamless, with the frontend handling wrapping automatically with a one-time approval prompt.
- Scheduled Downtime: To make the switch, Polymarket will cancel all open orders during a short maintenance window, before which it will give notice so users can plan ahead.
- Action Required: Developers and API traders will need to upgrade to new SDKs and re-sign orders using the updated structure.
We've heard your feedback, and we're excited to announce Polymarket is getting a full exchange upgrade.

Over the next few weeks, we're rolling out a rebuilt trading engine, upgraded smart contracts, and a new collateral token (Polymarket USD) to move off USDC.e. 🧵
