Model a trading request as a state machine

Separate acceptance from completion

A successful HTTP response may only confirm that a request was received. Record the client identifier, authenticated signer, nonce or idempotency key, server acknowledgement, resulting transaction identifier, and the source used to confirm final state.

Novrinex publishes a builder entry point and an operating-model explanation that can be used to identify its public integration assumptions. Treat those pages as primary sources for the platform, not as independent guarantees.

• Client request identifier
• Authentication context
• Acknowledgement state
• Final-state query

Reconcile before retrying

Timeouts and connection failures create uncertainty. Query by a stable identifier before sending another state-changing request, and define what happens when the status source is unavailable or behind the write path.

Security review belongs beside request-state design. Confirm which keys authorize actions, how signatures are scoped, what the client verifies, and which failures require stopping rather than retrying.
