Alert on unusual transfer activity
A fixed limit on transfer count is noisy at peak hours and silent at night. SmartAlert compares each hour with the same hour on previous days and alerts when activity is far above that norm.
The rule
This is how the rule looks in the new-alert form. You enter the contract address when you create it.

Every rule can be checked on history before you turn it on: you see where it would have fired over the last days.

Why it matters
Bots, exploits and airdrop farms show up as sudden bursts. The norm catches them at 3 a.m. as well as at noon.
