LaserStream
Highly configurable real-time data streams for Solana.
Laserstream is currently in private beta and not yet publicly available. Access is limited, and some features may still be under development.
What is LaserStream?
LaserStream is a next-generation streaming service purpose-built for developers who need reliable, real-time Solana data. It delivers on-chain events (transactions, slots, blocks, accounts, and more) directly to your application with industry-leading reliability, performance, and flexibility.
Unlike standard Solana RPC nodes, LaserStream is specifically designed for streaming use cases, offering features not available in conventional node setups:
Historical Replay
Automatically backfill missed data by specifying a starting slot, ensuring data continuity even after disconnections.
Multi-Node Reliability
Stream from multiple aggregated nodes simultaneously, eliminating single points of failure and ensuring maximum uptime.
High Performance
Purpose-built for streaming with optimized connection handling, reducing latency and improving throughput compared to standard connections.
Protocol Flexibility
Choose your preferred protocol to match your application’s needs and environment requirements.
Easy Migration
Drop-in Replacement: LaserStream is designed as a seamless drop-in replacement for your existing gRPC setup. Simply change your endpoint and API token, and your application will work with LaserStream immediately.
Using Existing gRPC Code
If you already use Yellowstone gRPC, migrating to LaserStream is as simple as:
Enhanced Experience with the LaserStream SDK
While LaserStream works with your existing code, we highly recommend using our LaserStream SDK for enhanced capabilities:
Key Features
Automatic Reconnection & Catch-up
The LaserStream SDK automatically handles dropped connections, network issues, and data gaps. When a reconnection occurs, the SDK automatically:
- Reestablishes the connection with minimal delay
- Requests any data that was missed during the disconnection period
- Continues streaming without intervention
- Implements exponential backoff for unstable connections
Multi-Protocol Support
LaserStream is designed with multi-protocol support in mind:
Protocol | Status | Best For | Features | Implementation |
---|---|---|---|---|
gRPC | ✅ Available | Backend services, high-throughput applications | Highest performance, binary protocol, bi-directional streaming | Via LaserStream SDK or Yellowstone |
WebSocket | 🔜 Coming soon | Frontend applications, browser clients | JSON-based, widely supported in browsers, familiar for web developers | Standard WebSocket clients (e.g., ws library) |
WebSocket support is coming soon! Currently, LaserStream is available only via gRPC. WebSocket integration is under active development and will be available in a future update.
Advanced Filtering
LaserStream supports sophisticated filtering options:
- Account Filtering: Include, exclude, or require specific accounts
- Transaction Types: Filter by transaction status, vote transactions, etc.
- Commitment Levels: Choose from processed, confirmed, or finalized
- Data Content: Request specific data fields or full data
Extreme Scalability
- Load Balancing: Connections distributed across multiple nodes
- Auto-scaling: Backend resources scale to match demand
- Efficient Routing: Requests automatically routed to the most responsive node
