Polymarket has unveiled one of the biggest infrastructure changes in its history, replacing bridged USDC.e with a new collateral token called Polymarket USD and rolling out an overhauled trading engine under CTF Exchange V2. According to the announcement, the new token is backed 1:1 by USDC and went live on April 6, 2026.
From bridged collateral to platform-issued Polymarket USD
The central change is Polymarket’s move away from Polygon’s bridged USDC.e as collateral across its prediction markets. In its place, the platform is introducing Polymarket USD, a wrapped stablecoin designed specifically for internal platform use rather than speculation or free market trading. Users holding USDC or USDC.e on the platform will see their balances converted through the interface, typically requiring only a single approval.
This gives Polymarket more direct control over the collateral rails backing its market outcome tokens and reduces its dependence on bridged assets. The company linked the move to its earlier 2026 partnership with Circle for native USDC infrastructure, framing the upgrade as part of a broader shift away from bridge exposure.
CTF Exchange V2 brings faster matching and wallet support
Alongside the collateral transition, Polymarket is also upgrading its exchange engine. The new CTF Exchange V2 introduces a simplified and optimized order structure, faster order matching, and improved logic for on-chain order attribution as well as fee collection and distribution. The company also said the update is designed to reduce gas costs.
Another notable addition is support for EIP-1271 signatures, which improves compatibility with smart contract wallets and account abstraction setups. For most everyday users, Polymarket said the migration should be largely seamless, with the interface handling collateral conversion automatically after the one-time approval step.
API traders and developers face a more involved migration
The transition is more technical for API traders, bot operators, and developers. Polymarket said these users will need to upgrade to the latest version of the CLOB-Client SDK, available in Typescript, Python, and Go. Advanced users operating outside the standard interface must manually call the wrap() function on the Collateral Onramp contract to convert funds into Polymarket USD.
All open orders will be canceled during a brief maintenance window, and the company said it will provide at least one week of notice before the cutover. Full deployment is expected to take two to three weeks from the date of the announcement. Developers can join Polymarket’s Discord developer channel for early testing access and migration support, while API change logs and SDK upgrade guides are expected to follow.
POLY speculation remains separate from this upgrade
The announcement also revived discussion around POLY, the long-rumored governance token tied to Polymarket. However, the company made clear that the two topics are separate. Polymarket USD is an infrastructure and collateral change, while POLY, if launched, would serve a governance or utility role. The platform’s chief marketing officer said in October 2025 that a POLY airdrop for users was planned, contingent on a successful relaunch in the United States. This latest update does not include any new details on governance design or an airdrop schedule.
Overall, the changes push Polymarket closer to a more fully on-chain financial protocol, with lower gas costs, stronger wallet compatibility, and reduced bridge dependence. Whether that also accelerates the path toward POLY or deeper decentralization remains an open question.
