Check base fees when a branch changes
A branch update can move implementation work forward. For branches tied to on-chain operations, add a fresh five block fee outlook to the update report.
Trigger
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Action
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.
Why this helps
A code update and a fee check are separate tasks, making it harder to keep release planning moving without another dashboard visit.
- Retrieve base fee predictions when a monitored branch changes.
- Include confidence estimates for the next five blocks in the report.
- Help coordinate timing without treating a code change as a transaction.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Blocknative once in the Notis portal.
- 2Create an automation and tell Notis to retrieve Blocknative base fee estimates when the monitored branch changes.
- 3Pick the Branch Changed trigger and choose where run reports should go.
- 4Test with one real branch change and review the fee outlook.
Questions about this workflow
What kinds of branch changes trigger this?
The event monitors commits pushed and branch protection changes. The action retrieves base fee estimates.
Does this tell me whether to submit a transaction now?
It provides predicted base fee information. A timing decision depends on transaction details and your own criteria.

Supported Triggers and Actions
Notis builds workflows that link GitHub to Blocknative. A trigger fires from one place; an action lands in another.
GitHub 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 Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
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.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
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.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
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.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
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.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
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.
