Prepare multichain monitoring for an investor transaction
Give Notis the transaction hash or account address and chains to monitor, then let it prepare the Blocknative subscription details.
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 activity spans chains, keeping track of which address or transaction to monitor can take repeated context switches.
- Prepare monitoring details for events across multiple chains.
- Keep the request tied to an Affinity deal or contact context.
- Reduce repeated manual setup when following a known address or transaction.
Setup
Build it in a few focused steps.
- 1Connect Affinity and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, ask Notis to prepare a Blocknative multichain subscription using the supplied transaction hash or account address and chain details.
- 4Choose a webhook trigger and select where run reports should go.
- 5Test with one real address or transaction and the chains you intend to monitor.
Questions about this workflow
Can this workflow infer which chains to monitor?
Provide the intended chain details with the webhook request. The listed action prepares subscription details across multiple chains.
Can Affinity start this automatically when a deal changes?
No Affinity trigger events are listed. Use a Notis webhook request to start the workflow.
Does this action itself report future transaction events?
It generates subscription details. A Blocknative multichain SDK connection is needed to use them for monitoring.
