Prepare one monitoring setup across chains
Turn context captured in a browser workflow into Blocknative multichain subscription details for follow-up.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Subscribe Multichain
Prepares a subscription to real-time transaction or account events across supported chains.
Why this helps
When work spans chains, reconstructing the right monitoring details by hand can interrupt the task you were doing.
- Prepare subscription details across multiple chains.
- Use address or transaction context captured during browser work.
- Reduce manual setup when starting multichain monitoring.
Setup
Build it in a few focused steps.
- 1Connect Airtop and Blocknative once in Notis.
- 2Create an automation and describe which captured address or transaction should be monitored.
- 3Tell Notis to prepare Blocknative multichain subscription details using the provided identifiers and chain context.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real address or transaction and the chain context you intend to monitor.
Questions about this workflow
Does this action begin monitoring on its own?
It generates websocket subscription details for the multichain SDK. The monitoring client must use those details.
What information should Airtop pass along?
Provide the relevant address or transaction identifier and the chain context needed for the subscription.
