Keep a current reference of supported gas oracles
Know which gas estimation oracles Blocknative supports when delivery workflows touch multiple networks.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Get Gas Oracles
Lists supported gas oracles by blockchain network.
Why this helps
When delivery-related transactions span networks, it takes extra effort to remember which gas estimation sources are available.
- Retrieve metadata for supported gas oracles across chains.
- Maintain a current reference without manually checking availability.
- Use the metadata to guide follow-up gas estimation choices.
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Blocknative once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3Describe that Notis should retrieve supported gas oracle metadata and summarize available options.
- 4Pick a recurring schedule and choose where run reports should go.
- 5Test with one real run and review the oracle metadata.
Questions about this workflow
Does this action return live transaction fees?
No. It returns metadata on supported gas oracles per chain. Use gas price or base fee actions when you need fee estimates.
Why use a scheduled trigger?
Addresszen provides no trigger events here, so a Notis schedule provides a grounded way to refresh the reference regularly.
