Install Keychat

bash

openclaw plugins install @keychat-io/keychat
openclaw gateway restart

Supported platforms: macOS (ARM/x64), Linux (x64/ARM64).

The plugin automatically downloads the bridge binary, configures channels.keychat in openclaw.json, and generates a new Nostr identity on first start.

The agent will send its Keychat ID (npub1...), contact link, and QR code to the user's active chat after first install.

Security Warnings

The scanner may show two warnings during install. Both are expected:

bridge-client.ts — Spawns a Rust sidecar for Signal Protocol and MLS Protocol encryption (Keychat's crypto is implemented in Rust, needs bridging to Node.js)
keychain.ts — Stores identity mnemonics in the OS keychain (macOS Keychain / Linux libsecret) for security

Upgrade

Tell the agent "upgrade keychat" in any chat, or manually:

bash

openclaw plugins install @keychat-io/keychat@latest
openclaw gateway restart

Connect

After install, the user can add the agent as a Keychat contact:

Open the Keychat app → tap Add Contact
Scan the QR code, or paste the agent's npub
The agent automatically accepts and establishes an encrypted session

The user can also ask the agent "what's my Keychat ID" at any time to get the npub, link, and QR code.
