Subscription methds

Subscription methods are available for WebSocket connections only, and allow you to wait for events instead of polling for them. For example, dapps can subscribe to logs and receive notifications when a specific event occurs.
The following subscription methods are available:
​eth_subscribe - Create a subscription to a particular event
​eth_unsubscribe - Cancel an active subscription
WebSocket support is limited to stateful WebSocket requests, for example using the eth_subscribe subscription method. Stateless WebSocket requests are not supported.

Polygon support for the newPendingTransactions subscription type is currently unavailable but is coming soon.
