About

In this lesson, we look at the code used when renting a vehicle from the application. Specifically, we look at disabling the button once the vehicle can be rented. Doing so allows us to dig deeper into Ethereum transactions and what happens when you create a transaction on the Ethereum blockchain- and what happens after it's created.
