Monitor pending transactions on demand
Start a live pending transaction stream when your intake system calls Notis.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Mempool Subscription
Tool to subscribe to real-time mempool updates for evm chains (ethereum, bnb, etc.). use after constructing your graphql subscription to stream pending transactions live.
Why this helps
Time sensitive transaction monitoring is easy to miss when it depends on manual setup.
- Start monitoring on demand
- Capture pending transaction context
- Reduce manual subscription setup
Setup
Build it in a few focused steps.
- 1Connect Bitquery in Notis once.
- 2Create an automation named Pending transaction monitor.
- 3Tell Notis to subscribe to the requested EVM mempool scope and summarize matching pending transactions.
- 4Pick the Notis webhook trigger.
- 5Choose where run reports go and test with one real webhook request.
