Watch for pending EVM transactions tied to your request
When you need a live view of pending transactions, send the EVM network and criteria in a request. Notis subscribes to Bitquery mempool updates and summarizes the stream.

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Why this helps
Checking pending activity manually can pull attention away from the work that needs a decision.
- Subscribes to real-time mempool updates for EVM chains.
- Focuses the watch on the supplied request criteria.
- Summarizes updates to make monitoring easier to scan.
Setup
Build it in a few focused steps.
- 1Connect AnyDB and Bitquery once in Notis.
- 2Create an automation in plain language or in Automations, New Automation.
- 3In one instruction, ask Notis to construct a GraphQL subscription for pending transactions on the specified EVM chain and criteria, then summarize incoming updates.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real supported EVM network and review the subscription updates.
Questions about this workflow
