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](https://eips.ethereum.org/EIPS/eip-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.
