name: Jito Rate Limits
description: >-
  Rate limit policy for Jito's Block Engine JSON-RPC, transactions proxy, tip
  floor REST endpoint, and ShredStream gRPC. The Block Engine enforces shared
  per-IP and per-UUID limits across regional endpoints; higher limits are
  available by requesting a UUID from Jito Labs. Limits change without notice
  — operators should treat published numbers as guidance and monitor 429s.
