OpenClaw Nostr Integration: Decentralized DMs Setup Guide

Nostr is a simple, open protocol for decentralized communication. No accounts to create with a company, no terms of service to accept, no risk of being banned. Your OpenClaw bot gets a cryptographic identity and communicates through relays that anyone can run. This guide covers setting up OpenClaw as a Nostr bot that responds to encrypted DMs.

Why Use Nostr With OpenClaw?

Every other messaging integration for OpenClaw depends on a centralized service. WhatsApp depends on Meta. Telegram depends on Telegram. Slack depends on Salesforce. If any of these companies decides to restrict bot access, change their API terms, or experience an outage, your OpenClaw assistant goes down.

Nostr removes this single point of failure. Your OpenClaw bot is identified by a cryptographic key pair, not by an account on someone else's server. Messages flow through relays — servers that anyone can run — and if one relay goes down, messages route through others automatically.

For privacy-conscious operators, Nostr also means no phone number required, no email verification, and no identity linkage to real-world information. Your OpenClaw bot exists as a public key, nothing more.

How Do You Generate Keys for the OpenClaw Bot?

Nostr identities are secp256k1 key pairs — the same cryptography Bitcoin uses. Generate a dedicated key pair for your OpenClaw bot:

# Using the nak CLI tool
nak key generate

# Output:
# Private key (nsec): nsec1xxxxxxxxxxxxxxxxxxxxxxxxx
# Public key (npub): npub1xxxxxxxxxxxxxxxxxxxxxxxxx

Store the private key (nsec) securely. This is the only credential your OpenClaw bot needs. The public key (npub) is what you share with users who want to DM the bot. Never expose the private key — anyone with it can impersonate your bot.

How Do You Configure OpenClaw for Nostr?

Add the Nostr connector to your OpenClaw configuration:

{
  "messaging": {
    "platform": "nostr",
    "private_key": "${NOSTR_PRIVATE_KEY}",
    "relays": [
      "wss://relay.damus.io",
      "wss://nos.lol",
      "wss://relay.nostr.band"
    ],
    "allowed_pubkeys": [
      "npub1your_personal_pubkey_here"
    ]
  }
}

The allowed_pubkeys list restricts who can interact with your bot. Without this, anyone who knows your bot's npub could send it messages and consume your API credits. Always set this for production deployments.

Set the environment variable and restart:

export NOSTR_PRIVATE_KEY="nsec1xxxxxxxxxxxxxxxxxxxxxxxxx"

Which Relays Should You Use?

Connect to multiple relays for redundancy. If one relay goes offline, your bot remains reachable through others. Recommended relay categories:

• High-availability public relays: relay.damus.io, nos.lol, relay.nostr.band — well-maintained, high uptime
• Paid relays: relay.nostr.com.au, nostr.wine — lower spam, better performance, small monthly fee
• Self-hosted relay: Run your own using strfry or nostream for guaranteed availability and privacy

For a production OpenClaw deployment, use 3-5 relays including at least one paid relay and ideally one self-hosted relay. This gives you redundancy without unnecessary relay overhead.

How Do You Secure the Nostr Integration?

Nostr security for OpenClaw involves three layers:

Key management: Store the bot's private key in an environment variable or secrets manager, never in the configuration file. Rotate keys periodically by generating a new key pair and updating your allowed contacts.

Access control: Use the allowed_pubkeys whitelist strictly. Only add pubkeys of people who should have access to your OpenClaw bot. Review the list monthly.

Message encryption: Nostr DMs are encrypted using NIP-04 (or the improved NIP-44). This prevents relay operators from reading message content. However, metadata (sender pubkey, recipient pubkey, timestamp) is visible to relays. If metadata privacy matters, run your own relay and connect only through it.

Rate limiting: Configure OpenClaw to limit the number of messages it processes per minute per pubkey. This prevents accidental API cost spikes from rapid-fire messages.

FAQ

What is Nostr and why would I use it with OpenClaw?

Nostr is a decentralized communication protocol where no single company controls accounts, messages, or access. Using Nostr with OpenClaw means your AI assistant cannot be deplatformed, censored, or shut down by a third party. Your identity is a cryptographic key pair, and messages flow through relays that you choose.

Are Nostr DMs with OpenClaw encrypted?

Yes. Nostr DMs use NIP-04 encryption (shared secret derived from both parties' keys) or the newer NIP-44 encryption for stronger security. Messages between you and your OpenClaw bot are encrypted so that relay operators cannot read them. However, metadata (who is messaging whom and when) is visible to relays.

Do I need to run my own Nostr relay for OpenClaw?

No. OpenClaw can connect to any public Nostr relay. However, running your own relay gives you guaranteed availability, lower latency, and the ability to enforce access policies. A personal Nostr relay can run on the same server as OpenClaw with minimal resource overhead.

Can I interact with OpenClaw from any Nostr client?

Yes. Once configured, you can DM your OpenClaw bot from any Nostr client — Damus (iOS), Amethyst (Android), Primal, Snort, or any other client that supports NIP-04 DMs. The bot responds through the same DM channel regardless of which client you use.
