Stop watching transaction hashes after review completion

Let closed reviews stop generating monitoring work.

Trigger

Recurring schedule

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

Action

Unsubscribe Transaction Hash

Tool to unsubscribe from transaction state change events for an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the unsubscription message.

Why this helps

Completed transaction investigations keep consuming attention because watches are never cleared.

  • Cuts unnecessary monitoring
  • Makes closure operationally complete
  • Leaves a cleanup report for auditability

Setup

Build it in a few focused steps.

  • 1Connect 21risk and Blocknative once in the Notis portal.
  • 2Create an automation describing the closure criteria and transaction hashes to release.
  • 3Pick a recurring cron trigger.
  • 4Choose a report channel for cleanup results.
  • 5Test with one completed transaction review.

Questions about this workflow

Does this delete the review record?

No, it prepares the Blocknative unsubscribe for the transaction watch.

What if closure data is missing?

The report should pause and identify the missing 21risk context.
