This subscription is unstable and only available if the validator was started with the --rpc-pubsub-enable-vote-subscription flag. The format of this subscription may change in the future.
This is an unstable RPC method that Helius does not support. This documentation is provided for reference only.

Endpoints

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.
