Polymarket Protocol V2 introduces new position tokens and contracts for trading, position operations, and resolution. Follow the guide for your integration while retaining CTF support. Existing CTF holdings are not converted.

​
What Changes

  • Market identifiers: Integrations select V2 position IDs or CTF token IDs using the market’s version.
  • Trading: V2 orders use ExchangeV3, signing domain version "3", and new approval targets. CLOB balance and allowance requests for V2 positions use CONDITIONAL-V2.
  • Position operations: V2 balances live in PositionManager. V2 split, merge, and redemption use Router, with updated calls and payout handling.

Migration Guides

For integrations already using pUSD and the CTFExchangeV2 order format, collateral, wallets, CLOB credentials, and endpoints stay the same.
