Polymarket Relayer Integration: Reliable Asynchronous Transaction Tracking

How to integrate the Polymarket Relayer when submission returns before an on-chain transaction hash is available.

Model submission as a state machine

A relayer submission can return a transaction identifier and initial state before a transaction hash exists. Store the identifier immediately and separate accepted, broadcast, confirmed and failed states.

Poll without duplicating actions

Use bounded backoff and an idempotency key. A timeout must trigger a status lookup, not an automatic duplicate submission, because the original request may still reach the chain.

Reconcile on-chain evidence

When a hash becomes available, verify receipt status and expected contract effects. Preserve failure details and distinguish relayer rejection, broadcast failure and reverted execution.

Expose operational metrics

Track time to broadcast, time to confirmation, terminal failure rate, stuck transactions and retry volume. Alert when state age exceeds the business deadline.
