Why this helps
Finding and interpreting fee trends can consume attention when all you need is a quick situational read.
- Get a distribution breakdown rather than one isolated quote.
- Make a quick fee assessment in a private conversation.
- Reduce context switching during transaction planning.
Setup
Build it in a few focused steps.
- 1Connect Slack and Blocknative to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Describe in one plain-language instruction that a DM asking for mempool fee trends should retrieve Blocknative's gas price distribution.
- 4Select the Slack direct message trigger and choose a run-report channel.
- 5Test by sending a real DM asking for the current fee distribution.
