Check upcoming base fees before an agreement-related transaction
Before a planned transaction tied to a merged or signed document, get Blocknative's next-five-block base fee predictions in a scheduled run report.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Get Base Fee Estimates
Retrieves real-time estimates of Ethereum's base and transaction fees for the next five blocks.
Why this helps
Preparing an agreement-related transaction can involve a separate, last-minute gas check that interrupts the work already underway.
- Retrieve next-five-block base fee and blob base fee predictions on a schedule.
- Include both 99% and 50% confidence estimates in the fee review.
- Keep a recurring fee check in a Notis run report.
Setup
Build it in a few focused steps.
- 1Connect ActiveMerge and Blocknative once in the Notis portal.
- 2Create a new automation and ask Notis to retrieve Blocknative base fee and blob base fee estimates for an upcoming agreement-related transaction.
- 3Choose the recurring schedule that fits the transaction preparation process.
- 4Choose where Notis run reports should go.
- 5Test with one real scheduled run and review the returned estimates.
Questions about this workflow
Does the estimate confirm that a transaction will be included?
No. It provides predictions for the next five blocks and confidence estimates to support fee planning.
Can this schedule know when an agreement is ready?
No ActiveMerge readiness trigger is listed. Choose a schedule that fits your process, or use a webhook sent by an external backend when the agreement is ready.
