Enhanced Websockets Overview (Beta)
Stream real-time transaction and account updates directly to your applications with our enhanced websocket integration.
What are Enhanced Websockets?
Helius provides Enhanced WebSockets in addition to Solana’s standard WebSocket methods. These enhanced WebSockets offer faster response times than traditional WebSockets. We support two subscription methods: transactionSubscribe and accountSubscribe.
This feature is available exclusively for business and professional plans. Please note that this is the Enhanced WebSocket, not Yellowstone Geyser. For Yellowstone Geyser functionality, a Dedicated Node is required.
Subscription Endpoints
Geyser-enhanced WebSockets are currently available on mainnet and devnet with the following URLs
Mainnet: wss://atlas-mainnet.helius-rpc.com/?api-key=<API_KEY>
Devnet: wss://atlas-devnet.helius-rpc.com/?api-key=<API_KEY>
Websockets have a 10-minute inactivity timer; to keep the WebSocket connection alive, it is highly recommended that health checks be implemented and that pings be sent every minute.
