Why this helps

- Subscribe to real-time mempool updates for supported EVM chains.
- Start the monitoring request with an HTTP webhook.
- Get pending transaction updates summarized for easier review.

Build it in a few focused steps.
- 1Connect Ai ml api and Bitquery once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis the outcome you want from any channel.
- 3In one instruction, identify the EVM chain and the pending transaction details you want Notis to summarize.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real chain request and confirm the subscription returns the expected mempool updates.
