Polymarket V2 Exchange Upgrade to Launch on April 22, Now Open for Testing

Polymarket Developers tweeted that the Polymarket V2 exchange upgrade will go live on April 22 and is currently open for testing by all users. Developers using the API or client must complete migration tasks before the launch: upgrade SDK/API integration, use the new exchange contract address and order structure, and switch collateral to pUSD (USDC.e must be wrapped into pUSD via the Collateral Onramp). During the upgrade, there will be approximately 1 hour of downtime (around 19:00 on April 22), during which all open limit orders will be canceled, but funds and positions will remain secure. The V1 exchange will cease operations once the migration is complete.
