Solana Yellowstone gRPC: Real-Time Data Streaming
High-performance, real-time Solana blockchain data streaming using gRPC protocol with advanced filtering and ultra-low latency delivery for developers.
What is Yellowstone gRPC?
Yellowstone gRPC provides ultra-low latency streaming of Solana blockchain data by tapping directly into Solana leaders to receive shreds as they’re produced. This delivers real-time data to your application with minimal delay.
High Performance
Binary protocol with efficient serialization for maximum throughput and minimal bandwidth usage
Real-time Streaming
Bidirectional streaming with immediate subscription creation and cancellation
Advanced Filtering
Precisely control what data you receive with account, transaction, and program filters
Multiple Data Types
Subscribe to accounts, transactions, slots, blocks, and entries in a single stream
Stream Types
Monitor account changes in real-time
Track balance updates, data modifications, ownership changes, and account creation/deletion events with precise filtering options.

Subscription Request Structure
Every gRPC subscription requires a properly structured request. Here’s how to build one:
Core Parameters
Commitment level for data consistency
processed
- Transaction processed by the nodeconfirmed
- Transaction confirmed by clusterfinalized
- Transaction finalized by cluster
Keep connection alive
Set to true
to receive pong messages every 15 seconds, preventing connection timeouts from load balancers or proxies.
Optimize data transfer
Request specific byte ranges from account data:
Filter Configuration
Account Filters
Account Filters
Array of account public keys to monitor (logical OR)
Array of owner public keys to monitor (logical OR)
DataSize and Memcmp filters (logical AND):
When multiple filter types are used, they operate as logical AND. Within arrays, values operate as logical OR.
Transaction Filters
Transaction Filters
Include/exclude vote transactions
Include/exclude failed transactions
Monitor specific transaction signature
Include transactions involving any of these accounts (logical OR)
Exclude transactions involving any of these accounts
Include transactions involving all of these accounts (logical AND)
Block Filters
Block Filters
Slot Filters
Slot Filters
When true
, only receive slot updates for the specified commitment level. When false
, receive updates for all commitment levels.
Example: Basic Transaction Monitoring
Here’s a complete example to get you started:
This is a basic example. For production use, implement proper error handling, reconnection logic, and data processing. See our detailed guides for complete implementations.
