Polymarket is executing what it describes as its largest infrastructure upgrade since launch — rebuilding its trading engine and replacing its core collateral asset with a new native collateral token.
The platform is moving away from bridged USDC (USDC.e) on Polygon and will instead settle positions in Polymarket USD, a proprietary token backed 1:1 by USDC held in reserve.
From Bridged Asset to Native Control
Polymarket has used USDC.e since launch/ It is a version of the stablecoin bridged from Ethereum to Polygon. That arrangement introduced bridge risk: the possibility of exploits or failures in the third-party software connecting the two chains.
The shift to a native collateral token removes that dependency. It also forms part of a broader engine overhaul the company calls CTF Exchange V2, which includes a rebuilt trading engine and a new hybrid central limit order book aimed at lower gas fees and faster execution.
The upgrade also adds support for multi-sig wallets such as Safe — a requirement for institutional clients and trading firms that need more granular security and governance controls.

Preparing for the U.S. Market
The timing is not incidental. Polymarket has been rebuilding its compliance architecture since settling a prior CFTC case, and a controlled, fully owned collateral layer is one of the structural prerequisites for a regulated U.S. relaunch.
Institutional capital and regulatory confidence both require a platform that doesn't depend on third-party bridge infrastructure. The transition to Polymarket USD will roll out over the next few weeks.
Regular users will see a one-click conversion prompt; API traders and bot operators will need to update their systems manually to interact with the new smart contracts. The upgrade follows record trading volumes.
Whether the new architecture is sufficient to satisfy U.S. regulators — or attract the institutional flows Polymarket is clearly positioning for — remains to be seen.
