Keet

Keet is a peer-to-peer chat application that offers features such as real-time audio/video calls, text chat, and file sharing. It was jointly launched by Bitfinex, Tether, and the software company Hypercore. Based on distributed technology, including a DHT (Distributed Hash Table) distributed database, Keet allows users to find and connect to each other on home and office networks in the real world through a technology called distributed peering, thereby forming a network of users. With built-in support for Bitcoin Lightning and USDt micro-payments, it is easy to implement and use powerful payment functions within the application.
