Why this helps
Network support can be easy to overlook when a transaction request arrives alongside address validation work.
- Retrieve supported chain metadata when a request arrives.
- Reduce manual lookup before selecting a network for further fee analysis.
- Keep the network support result alongside the incoming request.
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Blocknative once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3Describe that an incoming delivery transaction request should retrieve supported chain metadata for review.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real request and inspect the returned chain information.
Questions about this workflow
