Trigger

Action

Subscribe Transaction Hash

Tool to subscribe to transaction state change events of an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the subscription message.

Why this helps

Following pending transactions often means copying a hash into a separate tool and remembering to keep checking status.

  • Prepare a subscription for transaction state changes
  • Start from a transaction hash received in email
  • Reduce the need to manually revisit pending status

Setup

Build it in a few focused steps.

  • 1Connect Agent Mail and Blocknative once in the Notis portal.
  • 2Create an automation in the portal or tell Notis in plain language to create one.
  • 3Describe the outcome in one instruction, including how to identify a transaction hash and that the Blocknative websocket connection must be established.
  • 4Pick New Email Received as the trigger and choose where run reports should go.
  • 5Test with one real email containing a transaction hash after establishing the websocket connection.
