- Polymarket is preparing a protocol upgrade that will introduce pUSD, a Polygon-based security token fully backed by USDC.
- The overhaul is designed to reduce failed trades, reduce gas costs, and improve order management across the platform.
Polymarket is preparing a Protocol upgrade It appears less cosmetic than structural, with a new collateral code and a redesigned trading structure aimed at fixing some of the platform’s most persistent points of friction.
According to the company DocumentsThe upgrade will offer Polymarket USD, or pUSD, which is… ERC-20 token on ribbed Which is fully supported by USDC.
In practice, pUSD will act as a technical representation of a user’s balance within the platform. When users deposit USDC, this balance appears as pUSD on Polymarket, and can be converted back to USDC upon withdrawal.
pUSD changes the plumbing, not the user’s routine
For most users, the front-end experience shouldn’t change much. Funds enter, the balance is shown, trades are made, and funds can be withdrawn. The difference lies at the bottom, in the leveling layer.
Polymarket says the protocol will continue to settle trading activity in native USDC, while pUSD acts as a collateral token within the platform. The company is clearly trying to make the system more capital efficient and easier to scale without turning the user flow into something more complex.
I also took care to frame pUSD conservatively. The token is described as an ERC-20 standard on Polygon, backed by USDC through contract-mandated smart withdrawal mechanisms, with no algorithmic peg and no partial reserve structure.
Fewer failed trades is the real selling point
Perhaps the most significant upgrade is the architecture surrounding the trading itself. Polymarket says the new CTFv2 and updated order book design aims to reduce uncorrelated failures, check-balance race conditions and other edge-case issues that caused trades to fail.
Fees will now be calculated at the time of matching rather than order placement, while order tracking will move to a timestamp-plus-signature model rather than relying on off-chain numbers. The company also says gas costs should fall because the new contracts use more efficient libraries.
Security is also being emphasized. CTFv2 contracts have been reviewed by Cantina and Quantstamp, and Polymarket says it plans to open source the smart contracts next week along with a bug bounty program. This suggests that the company understands that the upgrade will be judged less by the launch message and more by whether the new system holds up cleanly once it’s up and running.
