Check which chains Blocknative supports
Resolve a network coverage question with a focused lookup instead of a manual search.
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 chain compatibility question can stall planning when the supported network list is not close at hand.
- Retrieve supported chain metadata on demand.
- Answer network coverage questions from a single request.
- Keep chain discovery separate from transaction execution.
Setup
Build it in a few focused steps.
- 1Connect 2chat and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis what to create from any channel.
- 3In one instruction, ask Notis to retrieve Blocknative supported chains metadata and summarize the networks relevant to the request.
- 4Choose the webhook trigger and where run reports should go.
- 5Test with one real network coverage question.
Questions about this workflow
Does this check whether a specific transaction will succeed?
No. It retrieves supported chain metadata. It does not simulate or validate a transaction.
Can the answer be limited to chains I name?
Yes. Include the networks you want summarized in the webhook request.
