When a client subscribes to a particular event, the Gnosis Chain node will send updates as soon as they occur. However, in some cases, the client may no longer be interested in receiving updates for a particular event. The eth_unsubscribe method can be used to cancel the following subscriptions:

eth_subscribe('newHeads')

eth_subscribe('newPendingTransactions')

eth_subscribe('logs')

eth_unsubscribe code examples

Note that subscriptions require a WebSocket connection and WebSocket cat for you to use this method in the console.

Install WebSocket cat with:

npm install -g wscat

$ wscat -c YOUR_CHAINSTACK_WEBSOCKET_ENDPOINT

# Wait for the connection to be established



Connected (press CTRL+C to quit)



> {"jsonrpc":"2.0","id": 1, "method": "eth_unsubscribe", "params": ["0x7529626735859f32962b10b19ee2e3eb"]}

This will remove the subscription matching the ID passed as a parameter.
