The Rabby Wallet is an open-source browser plugin designed for the DeFi ecosystem, offering users a more secure and user-friendly multi-chain experience. In this guide, we will walk you through the process of integrating Rabby Wallet into your decentralized application (dapp) with minimal development cost and hassle.

Guideline for Integrating Rabby Wallet

To streamline the integration of Rabby Wallet in your dapp, you just need to tweak the connection logic a bit. Let’s break down the problem and the solutions:

Understanding the Problem

When a dapp connects to an extension wallet, the process generally unfolds like this:

• The extension wallet integrates an Ethereum object into the dapp page during its load.
• The dapp checks for this Ethereum object to see if an extension wallet is present.
• If found, all subsequent interactions are managed via this Ethereum object.
• If not detected, the dapp prompts users to download a new wallet.

However, many dapps mistakenly interpret the detected Ethereum object as MetaMask and display a connect button for it, leading to user confusion since any Web3 wallet can inject this object.

Implementing the Solution

To alleviate this confusion, here’s what you can do:

• On your connection page, display connection buttons for both MetaMask and Rabby Wallet when the Ethereum object is detected.
• If the Ethereum object is not detected, recommend users to download the appropriate extension wallets and provide links for both MetaMask and Rabby Wallet.

By making these simple UI adjustments, you won’t need to alter your core business logic, keeping the integration process smooth and cost-effective. For visual guidance, you can refer to debank.com.

Potential Issues

We should also be aware that if a user has the Rabby Wallet installed and clicks the MetaMask connection button, they will still end up interacting with the Rabby Wallet—and vice versa. This situation is unlikely to happen but if it does, it’s usually not problematic from the user’s perspective.

Installation Dependencies

Before you dive into development, ensure that you have the necessary dependencies installed:

1. Install Node.js version 14 or later.
2. Install Yarn using: npm install -g yarn
3. Run yarn to install all required dependencies.

Development Steps

For developing with file watching and logging capabilities, execute:

yarn build:dev

This allows you to see requests sent by the dapp in the website console, with notifications remaining active even when focus is lost. For creating a production package, use:

yarn build:pro

which will place the build files in the dist folder.

Architecture Overview

To effectively manage interactions within the wallet, Rabby Wallet employs several scripts that operate in various contexts.

Details of Key Scripts

• background.js: Manages async requests and encryption, storing user keyrings and preferences locally.
• content-script: Injected at document start, it interacts with the dapp’s DOM using broadcastChannel.
• pageProvider.js: Injected into the dapp to mount the Ethereum object onto the window, facilitating communication between the content-script and background.js.
• ui: Handles user interface through HTML pages for notifications, main interaction, and popup notifications.

Troubleshooting

If you encounter any issues, here are some troubleshooting ideas:

• Ensure you have the latest version of Rabby Wallet installed.
• Check for any console errors during connection attempts.
• Verify that your UI correctly displays both MetaMask and Rabby Wallet buttons as intended.
