coderClaw

Nostr

Status: Optional plugin (disabled by default).

Nostr is a decentralized protocol for social networking. This channel enables CoderClaw to receive and respond to encrypted direct messages (DMs) via NIP-04.

Install (on demand)

Onboarding (recommended)

• The onboarding wizard (coderclaw onboard) and coderclaw channels add list optional channel plugins.
• Selecting Nostr prompts you to install the plugin on demand.

Install defaults:

• Dev channel + git checkout available: uses the local plugin path.
• Stable/Beta: downloads from npm.

You can always override the choice in the prompt.

Manual install

coderclaw plugins install @coderclaw/nostr

Use a local checkout (dev workflows):

coderclaw plugins install --link <path-to-coderclaw>/extensions/nostr

Restart the Gateway after installing or enabling plugins.

Quick setup

1. Generate a Nostr keypair (if needed):

# Using nak
nak key generate

1. Add to config:

{
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}"
    }
  }
}

1. Export the key:

export NOSTR_PRIVATE_KEY="nsec1..."

1. Restart the Gateway.

Configuration reference

Key	Type	Default	Description
privateKey	string	required	Private key in nsec or hex format
relays	string[]	['wss://relay.damus.io', 'wss://nos.lol']	Relay URLs (WebSocket)
dmPolicy	string	pairing	DM access policy
allowFrom	string[]	[]	Allowed sender pubkeys
enabled	boolean	true	Enable/disable channel
name	string	-	Display name
profile	object	-	NIP-01 profile metadata

Profile metadata

Profile data is published as a NIP-01 kind:0 event. You can manage it from the Control UI (Channels -> Nostr -> Profile) or set it directly in config.

Example:

{
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}",
      "profile": {
        "name": "coderclaw",
        "displayName": "CoderClaw",
        "about": "Personal assistant DM bot",
        "picture": "https://example.com/avatar.png",
        "banner": "https://example.com/banner.png",
        "website": "https://example.com",
        "nip05": "[email protected]",
        "lud16": "[email protected]"
      }
    }
  }
}

Notes:

• Profile URLs must use https://.
• Importing from relays merges fields and preserves local overrides.

Access control

DM policies

• pairing (default): unknown senders get a pairing code.
• allowlist: only pubkeys in allowFrom can DM.
• open: public inbound DMs (requires allowFrom: ["*"]).
• disabled: ignore inbound DMs.

Allowlist example

{
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}",
      "dmPolicy": "allowlist",
      "allowFrom": ["npub1abc...", "npub1xyz..."]
    }
  }
}

Key formats

Accepted formats:

• Private key: nsec... or 64-char hex
• Pubkeys (allowFrom): npub... or hex

Relays

Defaults: relay.damus.io and nos.lol.

{
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}",
      "relays": ["wss://relay.damus.io", "wss://relay.primal.net", "wss://nostr.wine"]
    }
  }
}

Tips:

• Use 2-3 relays for redundancy.
• Avoid too many relays (latency, duplication).
• Paid relays can improve reliability.
• Local relays are fine for testing (ws://localhost:7777).

Protocol support

NIP	Status	Description
NIP-01	Supported	Basic event format + profile metadata
NIP-04	Supported	Encrypted DMs (kind:4)
NIP-17	Planned	Gift-wrapped DMs
NIP-44	Planned	Versioned encryption

Testing

Local relay

# Start strfry
docker run -p 7777:7777 ghcr.io/hoytech/strfry

{
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}",
      "relays": ["ws://localhost:7777"]
    }
  }
}

Manual test

1. Note the bot pubkey (npub) from logs.
2. Open a Nostr client (Damus, Amethyst, etc.).
3. DM the bot pubkey.
4. Verify the response.

Troubleshooting

Not receiving messages

• Verify the private key is valid.
• Ensure relay URLs are reachable and use wss:// (or ws:// for local).
• Confirm enabled is not false.
• Check Gateway logs for relay connection errors.

Not sending responses

• Check relay accepts writes.
• Verify outbound connectivity.
• Watch for relay rate limits.

Duplicate responses

• Expected when using multiple relays.
• Messages are deduplicated by event ID; only the first delivery triggers a response.

Security

• Never commit private keys.
• Use environment variables for keys.
• Consider allowlist for production bots.

Limitations (MVP)

• Direct messages only (no group chats).
• No media attachments.
• NIP-04 only (NIP-17 gift-wrap planned).
