Start transaction monitoring from a submitted hash

Capture the hash once and prepare status monitoring immediately.

Trigger

New Form Response

Triggers when a respondent completes and submits the form.

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

Transaction hashes are often copied into separate monitoring tools by hand, delaying alerts about pending or confirmed states.

  • Reduces manual hash handling
  • Prepares status change monitoring quickly
  • Keeps the monitoring request traceable

Setup

Build it in a few focused steps.

  • 1Connect Typeform and Blocknative in Notis once.
  • 2Create an automation telling Notis to extract the Ethereum transaction hash and prepare the Blocknative subscription message for its state changes.
  • 3Pick New Form Response as the trigger.
  • 4Choose a report destination and test with one real hash.

Questions about this workflow

What if the hash is malformed?

Notis should flag the response for correction instead of preparing a subscription with invalid data.

Will I receive alerts automatically?

The action prepares the subscription details. Your websocket client or connected process must consume the events.
