Websockets are available on mainnet and devnet with the following URLs:

  • Mainnet wss://mainnet.helius-rpc.com/?api-key=<API_KEY>
  • Devnet wss://devnet.helius-rpc.com/?api-key=<API_KEY>
Websockets have a 10-minute inactivity timer; implementing health checks and sending pings every minute is heavily recommended to keep the websocket connection alive.
