Chapter 4. Wallets
This chapter covers
- Automating payments
- Creating and managing keys
- Making simple, secure key backups
So far, we’ve done nothing to improve the user experience for the company’s coworkers using the cookie token spreadsheet. The situation has become worse for users because emails to Lisa now need more information than in the beginning. On top of this, users should take extra steps to use multiple addresses to preserve their privacy.
In this chapter, we’ll build a mobile app, called a wallet (figure 4.1), that handles many of the common tasks users want to perform. This wallet will create new addresses, store private keys, simplify how addresses are transferred between users, and automate the payment process.
