Polymarket Protocol Upgrade and pUSD: What the Official Docs Signal
Polymarket announced on April 6, 2026, that it will roll out a full exchange upgrade including a rebuilt trading engine, upgraded smart contracts, and a new collateral token called Polymarket USD, marking the platform’s shift away from USDC.e.
The announcement, posted by the platform’s official account, described the changes as arriving “over the next few weeks.” The upgrade introduces Polymarket USD (pUSD) as the new settlement asset, replacing the bridged USDC.e token that has served as Polymarket’s collateral layer on Polygon.
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. 🧵

What Official Documentation Signals About the Upgrade
The core of the announcement centers on three components: a rebuilt trading engine, upgraded smart contracts, and the introduction of pUSD as a replacement for USDC.e. Polymarket framed the changes as a direct response to user feedback, according to its April 6 post.
The move away from USDC.e follows groundwork laid earlier this year. Circle’s February 5, 2026, press release confirmed that native USDC would power settlement for Polymarket users, explicitly noting the platform was using USDC.e on Polygon and planned to shift to USDC in the coming months.
According to secondary coverage, pUSD will reportedly be backed 1:1 by USDC, with frontend wrapping handled automatically for most users. This claim has not been confirmed directly in accessible Polymarket documentation, so it should be treated as unverified.
Polymarket’s live bridge endpoint currently lists 163 supported assets across 13 chains, with USDC available on 9 chains. On Polygon specifically, both USDC and USDC.e remain listed as supported assets, each with a minimum checkout threshold of $2, indicating the migration has been announced but not yet completed.
USDC itself trades at $0.999845 with a market capitalization of roughly $78.7 billion, reinforcing that the underlying stablecoin infrastructure Polymarket is building on remains stable during the transition period.
Why pUSD Could Matter for Polymarket’s Trading Stack
Introducing a platform-native collateral token rather than relying on a bridged asset addresses a structural risk. USDC.e is a bridged version of USDC on Polygon, meaning it carries bridge-layer dependencies that a native or wrapped token could eliminate.
For traders and liquidity providers on Polymarket, the shift could simplify settlement mechanics. If pUSD wrapping is indeed automatic at the frontend level, as secondary reports suggest, most users may not need to manage the token swap manually. The combination of upgraded smart contracts and a new trading engine could also affect order execution and matching speeds, though Polymarket has not published specific performance benchmarks.
According to unconfirmed reports from a PolymarketDevs thread, the new CTF Exchange V2 contract simplifies order structures, improves order matching, adds ERC-1271 signature support, and introduces builder codes. These details have not been independently verified from the developer post directly.
The broader crypto market context adds a layer of caution to any platform migration. The Fear & Greed Index sits at 15, deep in “Extreme Fear” territory. Major infrastructure changes during periods of low market confidence tend to attract closer scrutiny from users wary of disruption, similar to how large institutional Bitcoin purchases by Strategy draw heightened attention during volatile stretches.
What Users and Observers Should Monitor Next
The announcement describes a rollout over “the next few weeks” from April 6, placing the expected completion window somewhere in late April or early May 2026. Users should watch for follow-up posts from Polymarket or PolymarketDevs confirming migration dates and any required user actions.
Key questions remain unanswered. Will existing USDC.e positions be automatically converted to pUSD, or will users need to manually migrate? What happens to open positions during the smart contract upgrade? Will the 163-asset bridge infrastructure change alongside the collateral migration?
The fact that Polymarket’s bridge still lists both USDC and USDC.e on Polygon with identical $2 minimums suggests the transition is in its early stages. Monitoring the bridge endpoint for changes, specifically the removal of USDC.e or the addition of pUSD, will be the most direct way to track progress.
For those following prediction market infrastructure alongside broader crypto developments like institutional Bitcoin accumulation signals or emerging token presale activity, Polymarket’s upgrade represents one of the more significant DeFi infrastructure shifts announced this quarter. Official Polymarket channels remain the most reliable source for confirmed rollout details.
