Check chain support before you launch
Validate network coverage at the moment you need it, before a launch or integration handoff.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Why this helps
A monitoring plan can fail late when the intended chain is not confirmed as supported.
- Confirm network coverage early
- Reduce launch day surprises
- Share a clear support summary
Setup
Build it in a few focused steps.
- 1Connect 0CodeKit and Blocknative in Notis once.
- 2Create an automation that retrieves supported chain metadata and checks the supplied launch networks.
- 3Choose a notis_webhook trigger for each launch readiness request.
- 4Choose the report destination and test with one real network list.
