Escalations lose momentum when the transaction is not actively watched after handoff.
- Preserves escalation focus
- Reduces manual status checks
- Creates a clear monitoring handoff

- 2Create an automation describing the escalation and transaction hash to monitor.
- 3Choose a webhook trigger for escalation requests.

- 5Test with one approved escalation hash.
Questions about this workflow
Can this watch a hash on any chain?
The transaction hash subscription is for an Ethereum transaction and requires the applicable Blocknative connection.
What if the hash is not included?
