Solana is fast. Geyser is faster. Yellowstone gRPC Geyser is a high-speed, plugin-based interface that streams live Solana blockchain data directly from validator memory, eliminating the latency of traditional RPC methods.

​
Geyser is available starting from Growth

Geyser is available as a separate paid add-on starting from the Growth plan.

​
Mainnet only

The Yellowstone gRPC Geyser plugin is only available on Solana mainnet. It is not available on Solana devnet.
Benefits
  • Real-time streaming of transactions, account updates, blocks, and slot changes.
  • Uses a standard gRPC interface with protobuf-formatted payloads.
  • Accessible from any language supporting gRPC (Python, Go, Rust, JavaScript).
  • Ideal for analytics, sniping bots, MEV strategies, data indexing, real-time dashboards, and compliance monitoring.
  • from_slot/fromSlot support to replay recent slots and recover events missed during a brief disconnect. For an example, see learning-examples/recover_missed_slots_with_from_slot.py in Solana Geyser Python tutorial. The replay buffer holds a limited number of recent slots, not full history. See Replay depth with from_slot below.

​
Jito ShredStream enabled by default

Chainstack Solana nodes have Jito ShredStream enabled by default, providing significantly enhanced performance for Yellowstone gRPC Geyser streaming. ShredStream accelerates block data propagation by delivering shreds directly to nodes, resulting in better consistency, improved tail latency, and higher reliability. No additional configuration is required.

​
Replay depth with from_slot

The from_slot field replays recent slots from a server-side ring buffer, so a client that briefly disconnects can reconnect and catch up without missing events. It is a reconnection-recovery mechanism, not a historical backfill. On Global Nodes, the buffer holds approximately the last 100 slots (around a minute). Requesting a from_slot older than the buffer returns an error: 
broadcast from <slot> is not available, last available: <slot>
For arbitrary historical data beyond the buffer, use the standard JSON-RPC methods (getBlock, getSignaturesForAddress, and getTransaction) instead of from_slot.
Need a deeper replay window? Dedicated Nodes can be configured with a larger from_slot buffer for latency-sensitive workloads. Contact us to set this up.

​
Enable the Yellowstone gRPC Geyser plugin

  1. Deploy a Solana Global Node
  2. Click on your deployed Solana node.
  3. Click Add-ons > Yellowstone gRPC Geyser Plugin > Install.
