TechFlow News: On April 27, prediction market platform Polymarket announced it will undergo an upgrade at 11:00 UTC on April 28, 2026, during which trading is expected to be suspended for one hour. This upgrade includes launching the new smart contract CTF Exchange V2, rebuilding 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 place new orders after the upgrade completes. However, most users require no additional action—only a one-time authorization is needed before their first trade post-upgrade. All protocol transactions will continue to settle in native USDC. Additionally, the CTFv2 contract has been audited by Cantina and Quantstamp, and Cantina’s bug bounty program is now live.
