Keychat

Super App for Humans and Agents.·keychat.io

Keychat is a decentralized super app built on the Nostr protocol and Bitcoin Lightning Network that combines sovereign identity, a Bitcoin wallet, secure end-to-end encrypted chat, and Mini Apps. It requires no phone number, email, or registration—users generate Nostr keys as their identity. It serves both humans (private messaging and Bitcoin payments) and AI agents, which can connect via the OpenClaw plugin.
