Polymarket Announces Own Stablecoin and Major Exchange Upgrade
CircleINFRASTRUCTUREPrediction market platform Polymarket is rolling out its biggest infrastructure update ever, including a rebuilt trading engine, upgraded smart contracts, and a new collateral token called Polymarket USD to replace USDC.e.
Polymarket's Biggest Infrastructure Overhaul Yet
Prediction market leader Polymarket has announced a sweeping upgrade to its technical infrastructure. Over the coming weeks, the platform will deploy a completely rebuilt trading engine, enhanced smart contracts, and a proprietary stablecoin — Polymarket USD — replacing USDC.e as the base collateral token.
"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. 🧵" — Polymarket (@Polymarket), original post
The team described the update as the most significant infrastructure change since the platform's launch, promising faster order execution, lower fees, and a more robust foundation for future growth.
Why This Matters
Polymarket is one of the most prominent decentralized prediction markets. Moving away from USDC.e — a bridged version of Circle's stablecoin — to a proprietary token backed directly by USDC simplifies the settlement layer and potentially reduces bridge-related smart contract risks. This architectural shift signals growing maturity in the prediction market sector, as platforms invest in bespoke infrastructure rather than relying on third-party bridged assets.
The upgrade also positions Polymarket to handle increasing trade volumes with improved performance and reduced friction for both retail and institutional participants.
CTF Exchange V2: Rebuilt Order Book
At the core of the upgrade is CTF Exchange V2, a new iteration of Polymarket's CTF Exchange contract. The updated version introduces several key improvements:
- Optimized order structure and improved matching logic
- Support for 1271 signatures
- Developer codes for on-chain tracking of order provenance
- Built-in fee collection and distribution mechanisms
To facilitate the transition to the new engine, all open orders will be canceled during a brief maintenance window.
Polymarket USD: USDC-Backed Stablecoin
The newly introduced Polymarket USD token will serve as the platform's primary collateral asset. It maintains a 1:1 peg with USDC.
According to the team, most users will barely notice the migration. The platform's interface will automatically handle the token swap after a single confirmation prompt. Power users interacting through the API, however, will need to manually convert their USDC or USDC.e holdings to Polymarket USD.
Updated Developer Tools
Alongside the exchange upgrade, Polymarket is preparing a new SDK for CLOB clients. The V1-to-V2 transition will happen automatically, but engineers are advised to update to the latest iteration of each client to ensure full compatibility with the new architecture.
In related news, Polymarket has previously been reported to be collaborating with analytics firm Palantir Technologies on a monitoring system for sports betting markets.
