The transition to Version 2 (V2) is specifically designed to reduce friction for both retail users and the high-frequency traders who provide much-needed liquidity. By rebuilding the exchange contracts from the ground up, Polymarket is preparing for a future where prediction markets are as liquid and responsive as traditional equity exchanges.
Introducing new exchange contracts and the shift to Polymarket USD
The core of this upgrade lies in the departure from legacy bridged assets. Historically, Polymarket utilized $USDC.e—a version of Circle’s stablecoin bridged to the Polygon network. To gain more direct control over the settlement layer and mitigate bridge-related risks, the platform is introducing Polymarket USD.
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. 🧵
This new collateral token is fully backed 1:1 by $USDC, ensuring that users have a stable, reliable medium for their event contracts. While retail users will see an automated transition through the UI, power users and those utilizing API-based trading strategies will need to cancel open orders and update their software development kits (SDKs) to remain compatible with the new order book structure.
Smart contract wallet support and developer-centric improvements
Beyond the collateral change, the V2 upgrade embraces the EIP-1271 standard. This is a technical milestone that allows smart contract-based wallets—such as Safe (formerly Gnosis Safe) or multisigs—to sign transactions directly.

If they keep the interest earned on that, at current rates that's an extra $54m/year in revenue https://t.co/VtLGBeEbgL
This functionality is essential for institutional participants and automated trading systems that require complex permission structures. By making the platform more “machine-friendly,” Polymarket is positioning itself as the primary data source and execution venue for real-world event forecasting.
I'm just happy that Polymarket is moving more into the crypto

Launching own stablecoin is a very huge step for all the ecosystem, waiting for more details on it
Maybe we will get 4% on all positions now? Insane https://t.co/OMM0fakuFY
The result is a cleaner foundation that offers lower gas costs and faster execution, solidifying the platform’s role as the infrastructure of choice for the 2026 election cycle and beyond.

Final Thoughts
This technical “spring cleaning” marks Polymarket’s evolution from a niche crypto application to a professional-grade financial exchange. The shift to a native collateral token is a bold move that enhances both safety and scalability.
