Clean up monitoring after a risk review closes
Close the loop by removing subscriptions that no longer serve an active review.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
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
Old subscriptions create noise and make active monitoring harder to find.
- Reduces alert noise
- Keeps active coverage easier to audit
- Creates a regular cleanup habit

Build it in a few focused steps.
- 1Connect 21risk and Blocknative once in the Notis portal.
- 2Create an automation describing how closed reviews identify subscriptions for removal.
- 3Pick a recurring cron trigger for cleanup.
- 4Choose where run reports should be delivered.
