We’re happy to see that users understand and appreciate the design of Keychat Mini Apps — combining web apps, public key login, and a Bitcoin wallet. BTW, we plan to add a Public Agent alongside Mini Apps later on. View quoted note →

We want the overall design of the Keychat protocol to be easy for anyone to understand, not just developers. View quoted note →

Attaching a Stamp (Client → Relay) When publishing an event to a relay that requires stamps, the client appends a Cashu token as the third element of the EVENT message array: ["EVENT", <event JSON>, "<cashu_token>"] View quoted note →

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. View quoted note →

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 View quoted note →

This NIP defines a mechanism for clients to attach ecash tokens (Cashu) to Nostr events as stamps — anonymous per-event micropayments to relays. Stamps solve two fundamental problems for the Nostr relay ecosystem: spam prevention and relay sustainability.

We now have two clients that speak the Keychat protocol and work seamlessly with each other. More independent clients are coming. View quoted note →

Maybe agents will adopt sovereign messaging before humans do. Humans are still locked into big-tech chat apps by network effects and habit, while agents can switch to open, self-sovereign protocols much faster. Then humans may end up learning from agents—gradually moving to sovereign messaging themselves. It’s a strange inversion. View quoted note →

After installing the Keychat plugin on OpenClaw, a public key ID is automatically generated for the agent. Users can simply add the agent as a friend through Keychat on their phone—an interaction that feels natural and intuitive. Unlike Telegram or Discord, there’s no need to apply for a platform-issued Bot ID and manually configure it inside the agent. By using a sovereign messaging app like Keychat, agents gain not only a smoother, more intuitive user experience, but also true autonomy. After all, who wants their agent to depend on a bot ID issued by a platform? View quoted note →

If you’ve been with Keychat for a while, you might remember an early experiment: Keychat used to generate two IDs by default from a single seed phrase. One was for chatting with human friends. The other was simply named “Bot” — for chatting with agents. At the time, we shipped two lightweight Q&A agents. You paid per answer in sats, and they replied. But the real idea was bigger: anyone should be able to create an agent, run it as a public service, and earn sats — in a user-sovereign messaging network where humans and agents can talk, trade, and collaborate. Conversation as a service. That vision didn’t stick back then for one simple reason: OpenClaw didn’t exist yet. Building an agent was still too hard for most users, so we paused the feature. Now OpenClaw changes the equation. It makes building and running your own agent dramatically easier. Today it’s mostly used for personal assistants — but we think public-facing agents won’t be far behind. That’s why we’re bringing this direction back with the Keychat plugin: enabling human ↔ agent chat, and also agent ↔ agent chat, all inside the same user-owned network. Close your eyes and picture it: a user-sovereign network, slowly growing — one agent, one conversation, one service at a time. View quoted note →

You can now use Keychat as a channel for your OpenClaw agent. Install the Keychat plugin on OpenClaw, and you’ll be able to chat with your agent in Keychat on both mobile and desktop. Your agent gets a full-featured chat app with: Sovereign ID (npub) Open relay network Signal-encrypted 1:1 chats + small groups MLS-encrypted large groups Continuously rotating receiving addresses (better metadata protection) Bitcoin wallet + estamp (coming soon) With Keychat, agents can talk to humans — and they can also talk to other agents. Keychat treats human users and agent users the same. --- Setup takes just a few minutes. In any existing channel (Telegram, Discord, webchat, etc.), tell your agent to run: openclaw plugins install @keychat-io/keychat openclaw gateway restart After the installation finishes and the gateway restarts, ask: “What’s your Keychat ID?” Your agent will reply with: Keychat ID: npub1… Keychat ID link:

Sovereign IDs, Bitcoin Wallet, Secure Chat, Mini Apps — all in Keychat.

Open the Keychat app → tap the link (or paste the npub) to add it as a contact. Ownership rule: the first person to add the agent becomes its owner. Any later contact requests require owner approval. --- During installation, OpenClaw’s security scanner may show two warnings — both are expected: Shell command execution (bridge-client.ts): launches a Rust sidecar used for Signal Protocol and MLS encryption. Shell command execution (keychain.ts): stores identity mnemonics in your OS keychain (macOS Keychain / Linux libsecret).
