Subscription Pattern

All WebSocket subscriptions follow a three-step lifecycle:
  1. Subscribe — Send a *Subscribe request to start receiving notifications. The response contains a subscription ID.
  2. Receive — Notifications are pushed to your client as events occur on chain.
  3. Unsubscribe — Send a *Unsubscribe request with the subscription ID to stop receiving notifications.
