Developing our wallets infrastructure

Now that we are able to retrieve live price data from exchanges, we turn to our Wallet definition. As you can see, it specifies the type of private attributes we expect for the data that it needs to handle, as well as the public data() method to create the list of data that needs to be saved to a database at some point.
