The Failed Transaction trigger alerts you any time a transaction directed at the monitored contract reverts or fails on-chain. Failed transactions often signal attempted exploits, misconfigured callers, or contract logic errors.

​
Use cases

Attackers frequently probe contracts with crafted calls that revert. A spike in failed transactions can be an early warning of a targeted attack.
Catch broken integrations or misconfigured bots that are sending transactions with wrong parameters before they cause downstream issues.
A regression in contract logic that causes previously valid calls to revert will immediately surface as failed transaction alerts.
