The prediction platform Polymarket is undergoing a major upgrade of its technical infrastructure, which includes the integration of a new order book and its own stablecoin.

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. đŸ§”

"In the coming weeks, we will launch an updated trading engine, enhanced smart contracts, and a new collateral token (Polymarket USD) to phase out the use of USDC.e," the announcement states.

The company describes this update as "the most significant infrastructure change since launch," promising "faster trade execution, lower fees, and a solid foundation for future development."

During the 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 order structure and matching;
  • supports 1271 signatures;
  • includes developer codes for tracking the origin of orders on-chain;
  • facilitates the collection and distribution of fees.

Polymarket USD

Polymarket is transitioning from USDC.e to a new token—Polymarket USD, which is backed by USDC at a 1:1 ratio.

The company claims that most users will not notice the migration. The interface will automatically execute the token swap after a single confirmation request.

Experienced users operating through the API will need to manually exchange USDC or USDC.e for Polymarket USD.

New SDK for CLOB Clients

The platform will provide a new toolkit for developers. The transition from version V1 to V2 will occur automatically, but engineers will need to use the latest iteration of each client.

As a reminder, Polymarket is working with analytics firm Palantir Technologies to develop a system for monitoring sports betting.
