Answer chain support questions from a webhook
Give internal systems a current answer about Blocknative network coverage.
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
Teams repeatedly ask whether a network is supported before starting work.
- Answer coverage questions quickly
- Centralize current chain metadata
- Reduce repeated manual checks
Setup
Build it in a few focused steps.
- 1Connect Blocknative in Notis once.
- 2Create an automation named Webhook chain support lookup.
- 3Tell Notis to retrieve supported chains and answer the network question in each webhook request.
- 4Choose a Notis webhook trigger.
- 5Select a report channel and test with one real request.
Questions about this workflow
Can it return all supported chains?
Yes. Ask for the complete current list or a filtered subset.
Does the webhook need a Google Doc?

Supported Triggers and Actions
Notis builds workflows that link Google Docs to Blocknative. A trigger fires from one place; an action lands in another.
Google Docs triggers
Blocknative actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Configure Mempool Filters
Tool to configure filters and abi decoding for ethereum mempool transactions. use after establishing a blocknative websocket connection to set up event filters and decoding.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Gas Price Distribution
Tool to retrieve the current mempool gas price distribution breakdown. use when analyzing gas price trends or preparing fee strategies.
New Document Created
Triggers when a new Google Doc is created. This trigger monitors Google Docs and fires when new documents are detected. Uses timestamp filtering to efficiently poll for new documents.
Get Gas Oracles
Tool to retrieve metadata on supported gas oracles per chain. use when you need to dynamically discover all available on-chain gas estimation oracles across networks.
Document Deleted
Triggers when an existing Google Doc is deleted (moved to trash). This trigger monitors Google Docs and fires when documents are trashed.
Get Gas Prices
Tool to fetch gas price estimates for specific inclusion probabilities. use when you need gas price ranges for the next block or next ~10 seconds.
Document Placeholder Filled
Triggers when a Google Doc's plain text changes such that a configured placeholder token/pattern is no longer present (i.e., the document has been filled in). This trigger monitors a specific Google Doc and fires when a placeholder pattern that was previously present is no longer found in the document's plain text.
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Document Search Update
Triggers when a Google Doc matching a user-defined search query is newly created or updated since the last poll. This trigger uses timestamp filtering to efficiently monitor documents.
Get Base Fee Estimates
Tool to get real-time predictions for base fee and blob base fee for the next 5 blocks. use when you need both 99% and 50% confidence estimates for upcoming blocks.
Document Structure Changed
Triggers when a Google Doc's structure changes (headers/footers added/removed, tables/images count changes). This trigger monitors a specific document for structural changes like: - Headers added or removed - Footers added or removed - Tables added or removed - Images (inline objects) added or removed - Positioned objects added or removed - Footnotes added or removed
Subscribe Multichain
Tool to generate websocket subscription details for events across multiple chains. use when preparing to track a transaction hash or account address across chains via blocknative multichain sdk.
Document Updated
Triggers when an existing Google Doc is updated or modified. This trigger monitors Google Docs and fires when documents are updated.
Subscribe Transaction Hash
Tool to subscribe to transaction state change events of an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the subscription message.
