Founded in 2017, Mask Network automatically encrypts users' social media posts and chats, which can only be decrypted by their friends. It currently supports Facebook and Twitter, with plans to expand to more platforms. In addition to encryption, Mask Network enables users to send and receive cryptocurrencies, interact with decentralized applications (DApps), and support Gitcoin grant campaigns directly from Twitter. It also offers decentralized storage and sharing functionality, creating a decentralized Applet (DApplet) ecosystem over existing social networks.
