LaserStream

Next-generation Solana data streaming with ultra-low latency, historical replay, and multi-node reliability. Purpose-built for high-performance applications.

Professional Plan Required: LaserStream is available for Professional plan subscribers. Upgrade your plan to access LaserStream’s enhanced streaming capabilities.

What is LaserStream?

LaserStream is a next-generation streaming service purpose-built for developers who need reliable, low-latency Solana data. It delivers on-chain events (transactions, slots, blocks, accounts, and more) directly to your application with industry-leading reliability, performance, and flexibility. Similar to our gRPC offerings, LaserStream nodes tap directly into Solana leaders to receive shreds as they’re produced, delivering ultra-low latency data to your application.

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 gRPC 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:

// Before: Using standard Yellowstone gRPC
const connection = new GeyserConnection(
  "your-current-endpoint.com",
  { token: "your-current-token" }
);

// After: Using LaserStream (just change endpoint and token)
const connection = new GeyserConnection(
  "https://laserstream-mainnet-ewr.helius-rpc.com", // Choose your closest region
  { token: "your-helius-api-key" }
);

Enhanced Experience with the LaserStream SDK

While LaserStream works with your existing code, we highly recommend using our LaserStream SDK for enhanced capabilities:

// Using the dedicated LaserStream SDK
import { subscribe, CommitmentLevel, LaserstreamConfig } from 'helius-laserstream';

const config = {
  apiKey: "your-helius-api-key",
  endpoint: "https://laserstream-mainnet-ewr.helius-rpc.com" // Choose your closest region
};

// The SDK automatically handles:
// - Connection management
// - Reconnection with backoff
// - Historical replay after disconnects
// - Subscription management
await subscribe(config, subscriptionRequest, handleData, handleError);

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:

• Reconnects with minimal delay
• Re-streams any data that was missed during the downtime
• Continues streaming without intervention

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

Endpoints & Regions

LaserStream is available in multiple regions worldwide for optimal performance. Choose the endpoint closest to your application’s location:

Mainnet Endpoints

Region	Location	Endpoint
ewr	Newark, NJ (near New York)	https://laserstream-mainnet-ewr.helius-rpc.com
pitt	Pittsburgh, US (Central)	https://laserstream-mainnet-pitt.helius-rpc.com
slc	Salt Lake City, US (West Coast)	https://laserstream-mainnet-slc.helius-rpc.com
ams	Amsterdam, Europe	https://laserstream-mainnet-ams.helius-rpc.com
fra	Frankfurt, Europe	https://laserstream-mainnet-fra.helius-rpc.com
tyo	Tokyo, Asia	https://laserstream-mainnet-tyo.helius-rpc.com
sgp	Singapore, Asia	https://laserstream-mainnet-sgp.helius-rpc.com

Devnet Endpoint

Network	Location	Endpoint
Devnet	Newark, NJ (near New York)	https://laserstream-devnet-ewr.helius-rpc.com

Choosing Your Network & Region:

• For production applications, use a mainnet endpoint closest to your server location. For example, if your server is in Frankfurt, use https://laserstream-mainnet-fra.helius-rpc.com.
• For development and testing, use the devnet endpoint: https://laserstream-devnet-ewr.helius-rpc.com.

Authentication & Availability

LaserStream uses your Helius API key for authentication. You can obtain your API key from the Helius Dashboard. Your API key serves as both your authentication token and grants access to LaserStream’s enhanced features.

Plan Requirement: LaserStream is available for Professional plan subscribers ($999/month). Professional plan users pay 3 credits per 0.1 MB for all LaserStream usage. You can upgrade your plan in the Helius Dashboard.
