Prepare multichain monitoring for an agreement address
When an agreement workflow calls for monitoring an address across chains, send the address and relevant context to Notis by webhook and 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
Setting up cross-chain monitoring can require manually carrying an address and its context from document work into a separate monitoring flow.
- Prepare multichain subscription details from a supplied address and context.
- Reduce manual handoff between document workflows and monitoring setup.
- Keep the prepared monitoring details in a Notis run report.
Setup
Build it in a few focused steps.
- 1Connect ActiveMerge and Blocknative once in the Notis portal.
- 2Create a new automation and describe how to prepare multichain subscription details from an address supplied by your process.
- 3Choose the webhook trigger and have an external backend send the address and chain context when monitoring is needed.
- 4Choose where Notis run reports should go.
- 5Test with one real address and the chain context required by your monitoring process.
Questions about this workflow
Will this subscribe the address automatically?
The listed action generates websocket subscription details. It prepares the details for monitoring; it does not establish a websocket connection by itself.
What must the webhook provide?
It should provide the address and enough chain context for the intended monitoring request. Do not rely on the document itself to supply data that is not present in the webhook.
