Transaction Pipeline

📘 Transaction Pipeline

The transaction pipeline is optimized for safety, determinism, and scaling.

Steps

1. Request Ingestion Request hits API → validated → queued.

2. Deduplication Check Idempotency key prevents duplicates.

3. Queue Buffering Workers monitor queue depth and scale as needed.

4. KMS Signing Worker serializes tx → KMS signs → signature returned.

5. Broadcast Signed transaction pushed to RPC endpoint.

6. Finalization Tracking Gateway tracks confirmation status and exposes it through /tx/:id.
