Refresh gas estimates when your planning sheet changes
Get current gas price estimates after a change to the cells your fee planning depends on.
Trigger
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Action
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.
Why this helps
A fee estimate can go stale while a spreadsheet plan is being revised, leaving you to remember to look it up again.
- Rechecks current gas estimates after relevant planning cells change.
- Cuts the need to switch tools for a routine fee lookup.
- Uses Blocknative inclusion probability estimates for an updated fee planning view.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to fetch Blocknative gas price estimates when the monitored planning range changes, using the chain and inclusion probabilities you specify.
- 4Choose Cell Range Values Changed as the trigger and select where run reports go.
- 5Test with one real change to the monitored range.
Questions about this workflow
What cells should I monitor?
Choose the range whose changes should prompt a fresh gas lookup. The action needs the chain and inclusion probabilities; specify these in your instruction if they are not available from the sheet.
Does the action write estimates back into Google Sheets?
The listed action retrieves estimates. Writing them into a sheet is not part of this workflow.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Blocknative. A trigger fires from one place; an action lands in another.
Google Sheets 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.
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
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.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
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.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Developer Metadata Changed
Triggers when developer metadata entries change (new/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
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.
