Clean up multichain monitoring automatically
End cross-chain watches when the originating system says the work is complete.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Unsubscribe Multichain
Tool to unsubscribe from events across multiple chains using the multichain sdk. use after stopping monitoring of an address or transaction to clean up resources, e.g., call: blocknative.unsubscribe({ id: '0x..', chainid: '0x1' }).
Why this helps
Multichain subscriptions are easy to forget after an incident, migration, or completed transaction.
- Close watches across all specified chains
- Reduce monitoring noise after completion
- Keep subscription lifecycle connected to your systems
Setup
Build it in a few focused steps.
- 1Connect Blocknative in Notis once.
- 2Create an automation for multichain watch cleanup.
- 3Tell Notis to read the identifier and chain details from the webhook payload, then prepare the Blocknative multichain unsubscribe request.
- 4Choose a Notis webhook trigger and its endpoint.
- 5Select a report channel and test with one real cleanup payload.
Questions about this workflow
Can this handle several chains in one request?
Yes. Include every chain that belongs to the multichain subscription in the webhook payload.
What if the identifier is missing?
Notis should report the incomplete payload and avoid preparing an ambiguous unsubscribe request.
