Realm is a community-driven open-source project that aims to create personalized metaverses. Their primary business activities include providing a virtual world platform where users can explore infinite realms, connect with others, and participate in immersive art, exhibitions, and events. Users can play games, collect rare NFTs, and build their own realms. Realm also focuses on bridging virtual and real-world impact by connecting gameplay to causes such as tree planting and plastic cleanup.
