MetaMask Integration on Site

Cryptocurrencies are becoming increasingly prevalent in our lives. This payment method is becoming more accessible due to the increase in the number of cryptocurrencies and their demand for everyday spending. The emergence of Web3 has had a significant impact on the development of the blockchain, providing greater anonymity and further expanding its boundaries. Web3 projects face difficulties in accepting payments. Most of these challenges can be solved by the MetaMask wallet.

In this article, we will discuss how to integrate MetaMask with a website. You will also learn why this wallet plays an important role in simplifying payment acceptance and why you should integrate it into your website.

What is MetaMask

MetaMask is the most popular Web3 wallet, originally created to interact with the Ethereum network, but now supporting many other EVM-compatible networks. Its popularity is due to its ease of use and extensive capabilities, including storing, sending, and exchanging cryptocurrencies. Users have complete control over their keys and data, which guarantees a high level of security and privacy.

Metamask has become a key element of the Web3 infrastructure, acting as an intermediary between users and a multitude of decentralised applications (dApps). Simply connecting your wallet to the site allows you to instantly access all the functionality of the application, ensuring a comfortable and secure interaction with blockchain-based platforms.

Why connect MetaMask to a website

MetaMask is a browser extension used to connect to decentralised applications (dApps) running on the Ethereum platform. By connecting MetaMask to your website, both owners and customers benefit.

Advantages for users:

• Security. MetaMask stores users' private keys locally on the device, ensuring a high level of security.
• Convenient login. Instead of repeatedly entering your username and password, you only need to click a button to authorise yourself in the application.
• Asset management. The ability to send cryptocurrencies, purchase NFTs, and manage ERC-20 tokens directly from the application interface.
• Working with different networks. Support for switching between the main Ethereum network (Mainnet), test networks (Testnets), and third-party blockchain platforms.

Benefits for website owners:

• Increased audience engagement thanks to a convenient way to interact with the platform.
• Increased conversion of purchases and transactions thanks to a simplified payment procedure via cryptocurrencies.
• Increased number of active users by integrating a simple login and transaction confirmation method.

Connecting MetaMask will allow your website to become part of the Ethereum blockchain ecosystem, providing users with a convenient and secure interface for working with digital assets and services.

Basic methods of MetaMask integration

There are several ways to integrate a Web3 crypto wallet:

• native integration via Web3.js;
• use of a specialised SDK;
• special plugins for WordPress.

Let's take a closer look at the features of each method.

Native integration via Web3.js

This is the classic method for connecting a MetaMask wallet. When you choose this option, you interact directly with Web3.js. This allows you to automatically embed the wallet into all pages of your website. This method does not require extensive programming knowledge and is ideal for small projects that are just starting out in Web3.

Using a specialised SDK

This method greatly simplifies the process of integrating the MetaMask payment gateway by providing ready-made tools and libraries for quickly connecting MetaMask to your application. It can be selected for implementation in larger projects, and the use of templates saves time.

One of the main advantages of using the SDK is its ability to support different platforms and devices. Developers get a single point of entry for interacting with MetaMask on both desktop computers and mobile devices. This eliminates the need to write different code for each individual platform, simplifying the development process and reducing the likelihood of bugs and inconsistencies.

The SDK implements advanced connection mechanisms, such as deep link, which allows you to instantly switch between the browser and the MetaMask mobile app. This means that users can comfortably use your app's services even on mobile devices, without having to manually copy addresses or switch to another app. Such integration significantly improves the user experience and increases audience engagement.

Developers can fine-tune connection parameters, including the selection of blockchain networks (chains) and connectors. This allows you to adapt your application to the specific requirements and preferences of your target audience, ensuring high accuracy and efficiency of interaction with the blockchain.

Today, the SDK supports all EVM-compatible networks. This allows you to use those cryptocurrencies that are popular for payment.

The SDK is available in various integration options, including popular libraries such as Wagmi, making it accessible and convenient for a wide range of developers using different technology stacks.

There are three main ways to integrate:

• via the command line interface (CLI),
• by cloning a ready-made template,
• or by manually installing it into an existing project.

Connecting MetaMask via the SDK is the optimal choice for developers who value simplicity, versatility, and performance. This approach ensures fast and reliable integration, minimises risks, and saves resources, allowing you to focus on the core functionality of your application.

Integration via WordPress plugins

Ideal for owners of websites built on the popular WordPress CMS. There are ready-made plugins that allow you to integrate MetaMask in just a couple of clicks.

Typical plugins:

• MetaPress. Provides easy login via MetaMask.
• Direct integration of MetaMask and WordPress accounts. Synchronisation of user profiles.
• MetaMask payment gateway for WooCommerce. Accepting payments in cryptocurrencies through the popular WooCommerce store.

Advantages:

• minimal technical complexity and quick installation;
• compatibility with the existing infrastructure of the WordPress website.

Disadvantages:

• Less flexible configuration compared to custom implementations;
• Regular plugin updates are required to maintain security and stability.

The table below provides recommendations for choosing a MetaMask integration method.

Additional aspects of MetaMask integration

In addition to the integration process itself, there are important nuances that affect the quality and usability of the service:

• Hardware wallet support. The ability to connect devices such as Ledger increases user confidence and improves security.
• Automatic redirection to MetaMask installation. Increased convenience for new users encountering the service for the first time.
• Network selection. Giving users a choice between the main Ethereum networks and test networks contributes to comfortable use and testing of new products.
• Compatibility with popular CMS and e-commerce platforms. Simplifies implementation and reduces technical barriers for owners of existing online resources.
