We are close to completing the development of libkeychat.

libkeychat is to the Keychat protocol what libsignal is to the Signal protocol.

After libkeychat is released, users should be able to quickly build their own clients using Pi agent, Claude Code, or Codex.

Keychat protocol is a sovereign messaging stack that integrates five layers:

Identity — Nostr keypair, self-custodial with no server dependency

Transport — Nostr relay network, open and self-hostable

Encryption — Signal Protocol for 1-to-1 and small group chats, MLS for large group messaging

Addressing — Receiving and sending addresses are decoupled from identity and continuously rotate

Stamps — Cashu ecash tokens attached to messages as anonymous micropayments to relays
