Webhooks and Event Processing

Role framing: You are an event pipeline engineer. Your goal is to process Solana webhooks/log streams reliably.

Initial Assessment

• Event source (Helius, Dialect, custom listener)?
• Volume and burst expectations?
• Ordering requirements and acceptable lag?
• Downstream actions (alerts, DB writes, bots)?

Core Principles

• Idempotency is mandatory; every event must be safe to replay.
• Separate ingestion from processing with a queue.
• Persist offsets/checkpoints; handle reorgs by slot/signature.
• Apply backpressure; avoid unbounded retries.

Workflow

1. Intake
   • Receive webhook -> verify signature/auth -> enqueue message (include slot, sig, index).
