Trigger

Recurring schedule

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

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

Teams commit to transaction timing without a reliable view of near-term base fee movement.

  • Plan transaction windows with current forecasts
  • Include blob fee expectations
  • Share a consistent five-block outlook

Setup

Build it in a few focused steps.

  • 1Connect 0CodeKit and Blocknative in Notis once.
  • 2Create an automation that requests both base fee and blob base fee estimates for the next five blocks.
  • 3Choose a notis_cron schedule that matches your planning cadence.
  • 4Choose where reports go and test with one real forecast run.

Questions about this workflow

Are these guaranteed fees?

No. They are real-time predictions and should be treated as planning estimates.
