Polymarket to complete full exchange upgrade within weeks

Polymarket said it will roll out a broad infrastructure upgrade over the next few weeks, including a rebuilt trading engine and upgraded smart contracts. The platform is also moving off $USDC.e and adopting a new native collateral asset, Polymarket USD. The changes are designed to improve execution speed and materially reduce gas costs as the exchange handles record transaction volumes. A scheduled maintenance period will cancel all open orders as part of the migration to the new technical foundation.
