# Address Balance Change Notifier
This script monitors the balance of a Bitcoin address every 24 hours and triggers an email notification if the balance has changed in the last 2 days. This Node.js script has been written to work on Microsofts Functions-as-a-Service (FaaS) offering, specifically [Azure Functions Timer Trigger](https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer). Rewriting it for a vanilla Node.js backend shouldn't require much effort though. Just implement a ```setIntervall()``` method to call the function at specific time intervalls.
