Polymarket is preparing a protocol upgrade that looks less cosmetic than structural, with a new collateral token and a redesigned trading architecture aimed at fixing some of the platform’s more persistent friction points.
According to the company’s documentation, the upgrade will introduce Polymarket USD, or pUSD, an ERC-20 token on Polygon that is fully backed by USDC.
In practical terms, pUSD will function as the technical representation of a user’s balance inside the platform. When users deposit USDC, that balance appears in pUSD form on Polymarket, and it can be swapped back into USDC on withdrawal.
pUSD changes the plumbing, not the user routine
For most users, the front-end experience is not supposed to change much. Funds go in, a balance appears, trades are placed, and money can be withdrawn. The difference sits underneath, in the settlement layer.
Polymarket says the protocol will continue settling trading activity in native USDC, while pUSD acts as the 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 complicated.
It also took care to frame pUSD conservatively. The token is described as a standard ERC-20 on Polygon, backed by USDC through smart contract-enforced withdrawal mechanics, with no algorithmic peg and no fractional reserve structure.
Fewer failed trades is the real selling point
The more important upgrade may be the architecture around trading itself. Polymarket says the new CTFv2 and updated order book design are intended to reduce nonce-related failures, balance-check race conditions and other edge-case problems that have caused failed trades.
Fees will now be calculated at match time instead of order placement, while order tracking will move to a timestamp-plus-signature model rather than relying on onchain nonces. The company also says gas costs should fall because the new contracts use more efficient libraries.
Security is being emphasized too. The CTFv2 contracts have been audited by Cantina and Quantstamp, and Polymarket says it plans to open-source the smart contracts next week alongside a bug bounty program. That suggests the company understands the upgrade will be judged less by the launch message and more by whether the new system holds up cleanly once it is live.
