Building an Idempotent Crypto Order Pipeline in Node.js

Short summary

Production crypto trading systems must implement idempotent order pipelines to prevent duplicate orders and data loss from retries and network failures. Pattern: store trade intents durably, use deterministic client order IDs, and query the exchange before retrying on ambiguity. Concrete Node.js/Postgres/Redis patterns for state management and crash recovery provided.

• •Idempotent pipelines prevent duplicate orders from retries, network timeouts, and reconnections
• •Use deterministic client order IDs to separate trade intents from exchange orders with atomic state transitions
• •Query existing orders before retrying on network ambiguity rather than blindly resubmitting
