Jito Streaming Surfaces

Real-time streaming surfaces from Jito infrastructure — the wss tip_stream for continuous bundle-tip percentile updates, the ShredstreamProxy SubscribeEntries gRPC method for sub-slot Solana shred delivery, and the SearcherService SubscribeBundleResults gRPC stream of bundle inclusion and rejection events.

  description: >-
    Real-time streaming endpoints exposed by Jito infrastructure: the WebSocket
    bundle tip stream and the gRPC ShredStream for low-latency Solana shred
    delivery. These are the canonical out-of-band feeds for searchers, HFT
    bots, and validators that need sub-slot insight into network state and
    bundle market pricing.
