A crypto wallet extension can have a variety of features, but let's start with the basics. In general, it will have 5 main features.

These features include multiple chain support, which allows the wallet to work with different blockchain networks. Multiple wallet support is also a key feature, enabling users to manage multiple wallets from a single interface.

The ability to send, receive, and swap tokens is another essential feature. This includes storing private keys securely, which is crucial for protecting user funds.

A simple and intuitive user interface is also a must-have for any crypto wallet extension. This makes it easy for users to navigate and use the wallet without getting overwhelmed.

Here are the main features of a crypto wallet extension:

To develop a crypto wallet extension, you'll need to handle user input parameters and call sendRawTransaction to retrieve token balances. This process is similar to creating an account, but instead of generating a seed phrase, you'll use the user-provided seed phrase to retrieve the private key.

Creating the Chrome extension source code involves several steps. You'll need to create a manifest.json file in the project's root to interact with Chrome regarding the extension and permissions. This file is crucial for the extension's functionality.

To manage storage, you can use Chrome.storage.local and Chrome.storage.session. These storage options allow you to store and retrieve data locally and across sessions, respectively.

Next, create a popup.html file for your extension's popup interface. This will be the user's entry point to interact with your extension.

To handle functions and variables related to the blockchain, create the AppView class. This class will process the mandatory features of your extension using a client.

To make your extension more dynamic, create hooks to react with storage. This will allow your extension to respond to changes in the user's storage.
