Keep a current list of supported chains
Refresh the available Blocknative network metadata and have Notis summarize the catalog for your team.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Why this helps
A stale list of supported networks can slow down decisions about where to monitor transactions or request gas data.
- Retrieve supported chain metadata from Blocknative.
- Receive the current catalog on a predictable schedule.
- Compare with prior results when you supply or retain earlier catalog data.
Setup
Build it in a few focused steps.
- 1Connect Blocknative once in the Notis portal.
- 2Create an automation in Automations, then New Automation, and name the chain catalog refresh.
- 3Tell Notis to retrieve supported chain metadata and summarize the available networks.
- 4Choose the recurring schedule and a report destination.
- 5Test with one real example; provide prior catalog data if you want a comparison.
Questions about this workflow
Does this automatically detect newly added chains?
It retrieves the current supported chain metadata. To identify changes, Notis needs a prior catalog to compare against.
Can it check gas prices for each chain?
No. This action retrieves chain metadata. Gas estimates require a separate gas price action and supported chain input.
What if no previous catalog is available?
The report can summarize the current catalog, but it cannot claim changes from an earlier state without prior data.
