  • Reduce repeated lookups
  • Keep investigation context together

Setup

Build it in a few focused steps.

  • 1Connect 1Password and Blocknative in Notis once.
  • 2Create an automation named Transaction hash cross-chain watch.
  • 3Tell Notis to subscribe through Blocknative multichain using the hash and chain set supplied by the webhook.
  • 4Pick the webhook trigger and choose where run reports go.
  • 5Test with one investigation hash.
