Polymarket CLOB V2 Integration Development: Production Checklist

What a production Polymarket CLOB V2 integration needs beyond an SDK upgrade: signing, attribution, reconciliation, pagination and controlled rollout.

Treat V2 as an execution migration

CLOB V2 is live on the standard production host and legacy V1-signed orders are not supported. Inventory every SDK, raw signer, order serializer and reconciliation job before changing production.

Rebuild the order lifecycle

Validate price and size rules before signing, generate deterministic client identifiers, handle partial fills and reconcile open orders after every reconnect. A successful request is not proof that local position state is correct.

Update discovery and pagination

Market discovery and execution are separate surfaces. Persist stable market and token identifiers, respect current keyset limits and paginate with cursors rather than assuming a single large response.

Deploy through measurable stages

Start with read-only market synchronization, then signed test fixtures and a restricted live canary. Compare local orders, remote orders, fills and balances before raising limits.
