Hello,
I saw this guide for monitoring ERC20 tokens: https://docs.openzeppelin.com/defender/guide-balance-automation-forta-sentinel
Is there something similar for monitoring ether balance? Is it possible with current Sentinel implementation?
Best regards,
Pedro Reyes.
Hey @Pedro_Reyes,
Sentinel right now is attached to events and function calls from contracts, so you can indirectly monitor a balance when some of the former happen.
If you need more fine-grained monitoring, you can always wire a Forta Detection Bot to a Defender Sentinel, so you can trigger alerts based on the balance of an account and check upon every block or any transaction the account does, which is more flexible.
I recommend you going through the Forta Detection Bot Docs, and take a look at some of the current Forta Bot Templates there are.
Also, a bot contest is going on right now if you also want to participate 
Best!
