Polymarket will upgrade on April 28, transferring collateral tokens from USDC.e to pUSD.
Deep Tide TechFlow News, April 27 — The prediction market platform Polymarket announced that it plans to upgrade at 11:00 UTC on April 28, 2026, with trading expected to be paused for 1 hour. This upgrade includes launching the new smart contract CTF Exchange V2, restructuring the order book system, and migrating collateral assets from USDC.e to the new collateral token Polymarket USD (pUSD).
Polymarket reminds users that all existing order books will be cleared during the upgrade, and users will need to re-enter their orders after the upgrade is complete. However, most users do not need to take additional action, only requiring a one-time authorization during their first trade. All trading activities on the protocol will still settle in native USDC. Additionally, the CTFv2 contract has been audited by Cantina and Quantstamp, with Cantina’s bug bounty program now live.
