In this chapter, we are going to build a simple digital wallet application based on Ethereum blockchain.

This chapter has been organized in a way that allows you to create your first Ethereum application without in-depth knowledge of blockchain and related technologies.

You are going to use the React library with the fantastic Ant Design components. You will also learn how to set up a personal blockchain for development purposes.

By the end of this chapter, you should have a good foundation project to build financial applications that can work with the Ethereum blockchain.

In this chapter, we will cover the following topics:

• Generating the project scaffold with React
• Integrating the Ant Design library
• Setting up a personal Ethereum blockchain
• Configuring the Ethereum JavaScript API
• Displaying Ethereum Node information
• Integrating with the application menu
• Rendering a list of accounts
• Showing our account balance
• Transferring ether from one account to another
• Packaging the application for distribution

Let's start our journey by generating a new React-based project that suits our digital wallet application's needs. But before that, let's quickly take a look at the technical requirements for this project.
