Notis

Keep a scheduled view of the next five blocks

Spot near term fee movement before it affects your operating plan.

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

Fee forecasts become stale between manual checks, especially during busy launches.

  • Keeps short term forecasts current
  • Separates base fee from blob fee movement
  • Supports repeatable launch operations

Setup

Build it in a few focused steps.

  • 1Connect Blocknative in Notis once.
  • 2Create an automation for your base fee watch.
  • 3Tell Notis to retrieve Blocknative predictions for the next five blocks and summarize changes using any baseline or threshold you provide.
  • 4Choose a Notis cron trigger and set the recurring cadence.
  • 5Choose a report channel and test the first scheduled result.

Questions about this workflow

Can it alert only on large changes?

Yes. Provide a change threshold in the instruction.

Is the forecast guaranteed?

No. It is a current prediction for the next five blocks and should inform, not replace, judgment.
