The prediction platform Polymarket is undergoing a major upgrade of its technical infrastructure. The integration of a new order book and its own stablecoin is planned.
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. 🧵

“Over the next few weeks, we will launch an updated trading engine, enhanced smart contracts, and a new collateral token (Polymarket USD) to move away from using USDC.e,” the announcement states.
The company describes the update as “the most significant infrastructure change since launch.” It will provide “faster trade execution, lower fees, and a reliable foundation for further development.”
To transition to the new engine, all open orders will be canceled during a brief maintenance period.
CTF Exchange V2
CTF Exchange V2 is the updated version of the Polymarket CTF Exchange contract. It performs the following functions:
- optimizes and simplifies the structure of orders and their matching;
- supports 1271 signature;
- includes developer codes for tracking the origin of orders on-chain;
- ensures the collection and distribution of fees.
Polymarket USD
Polymarket is transitioning from USDC.e to a new token—Polymarket USD. It is backed by USDC at a 1:1 ratio.
The company claims most users will not notice the migration. The interface will automatically perform the token swap after a single confirmation request.
Experienced users working through the API must exchange USDC or USDC.e for Polymarket USD themselves.
New SDK for CLOB Clients
The platform will prepare a new set of tools for developers. The transition from version V1 to V2 will occur automatically, but engineers need to use the latest iteration of each client.
As reported earlier, Polymarket, in collaboration with the analytics company Palantir Technologies, will develop a system for monitoring sports betting.
