Polymarket's V2 exchange upgrades go live April 22nd. The upgraded exchange is now open to all for testing. 🚨 If you use our API or clients, there's migration work to do before then: → Upgrade your SDK/ API integration → New exchange contract addresses & order struct → Collateral moves to pUSD (wrap USDC.e via the Collateral Onramp) We expect ~1 hour of downtime on April 22nd at ~11am UTC. Open limit orders will be cancelled during the switch. Funds and positions are safe. Please note that the V1 exchange will stop working after the migration.
