Preference Storage for DApps using Metamask with Next.js

Web3 applications, such as DAOs and DApps, are gaining popularity due to their ability to provide personalized and private user experiences. This project explores enhancing user experience through a preference storage system using Next.js, which allows users to customize and maintain their interface settings across different platforms. The authentication process relies on blockchain wallets like Metamask, which manage crypto assets and provide a secure way to authenticate users. The project involves setting up a Redis database to store user preferences, configuring API files to handle data storage and retrieval, and creating a user interface that allows users to set and save preferences such as theme and greeting messages. By connecting through Metamask and utilizing the Redis database, users can enjoy a consistent and personalized experience across multiple sites. The project also offers the potential for further customization and scalability, enabling developers to adapt it to various use cases. A demonstration of the finished project is available on GitHub, accompanied by a quick deploy button for Vercel deployment, which integrates with Upstash Redis automatically.
