:milky_way: Tracking Expenses Securely!

Jarvis is A web application backed by the power of Decentralization! The motive of the application is to assist the user in managing and maintaining his/her transactions. A transaction can be either in the form of income or expense. This application provides visualizations in the form of graphs giving users the ability to track by visualizing his/her expenses over a period of time. The application provides the functionality to export transactions in an Excel file. The user can also add transactions through voice commands with a simple click of a button. In addition, all data that the user generates is stored on the blockchain in a decentralized manner powered by Ethereum, which prevents the risks of illegal tampering with the data.
