⚠️ RECKLESS MODE - READ THIS FIRST ⚠️

Giving a bot access to your money is dangerous.

• Use a wallet with a small amount you can afford to lose
• NEVER enable this on a bot that outsiders can access via chat
• This skill is intended for personal/internal use only
• The bot can send payments on your behalf — treat credentials like cash
• Start small, test thoroughly, proceed with extreme caution

You have been warned. This is reckless mode.

Installation

1. Download LNI Binary

cd ~/workspace/skills/lightning
npm run download

This downloads the prebuilt native binary for your platform from GitHub Releases.

2. Configure Backend

Create ~/.lightning-config.json:

CLN (Core Lightning):

{
  "backend": "cln",
  "url": "https://your-cln-node:3010",
  "rune": "your-rune-token",
  "acceptInvalidCerts": true
}

LND:

{
  "backend": "lnd",
  "url": "https://your-lnd-node:8080",
  "macaroon": "hex-encoded-admin-macaroon",
  "acceptInvalidCerts": true
}

Phoenixd:

{
  "backend": "phoenixd",
  "url": "http://127.0.0.1:9740",
  "password": "your-phoenixd-password"
}

NWC (Nostr Wallet Connect):

{
  "backend": "nwc",
  "nwcUri": "nostr+walletconnect://..."
}

Spark (Breez SDK):

{
  "backend": "spark",
  "apiKey": "your-breez-api-key",
  "mnemonic": "your 12 word seed",
  "storageDir": "/home/clawd/lightning-data",
  "network": "mainnet"
}

Provisioning a New Spark Wallet

If the user doesn't have a Spark wallet yet, walk them through these steps:

Step 1: Generate a 12-word mnemonic seed

Use the built-in LNI helper:

const lni = require('./lib/lni_js.node');
const mnemonic = lni.generateMnemonic();
console.log(mnemonic);

⚠️ Tell the user to back up their seed phrase securely — it controls their funds.

Step 2: Request a Breez API key

The user must request an API key from Breez for the nodeless (Spark) SDK implementation:

1. Go to: https://breez.technology/request-api-key/#contact-us-form-sdk
2. Fill in their email and select the Nodeless (Greenlight) implementation
3. Submit the form — Breez will email the API key

Step 3: Retrieve the API key

After submitting the form, ask the user:

"Do you have an email skill configured (e.g., ProtonMail)? I can check your inbox for the Breez API key if you'd like."

If they approve, use the email skill to search for the Breez API key email and extract it.

Step 4: Create the config

Once you have the mnemonic and API key, write ~/.lightning-config.json:

{
  "backend": "spark",
  "apiKey": "<breez-api-key>",
  "mnemonic": "<12-word-seed>",
  "storageDir": "/home/clawd/lightning-data",
  "network": "mainnet"
}

Step 5: Connect and verify

const node = new lni.SparkNode(config);
await node.connect();
const info = await node.getInfo();

Strike/Blink/Speed (Custodial):

{
  "backend": "strike",
  "apiKey": "your-api-key"
}

Tor Support (SOCKS5 Proxy)

Connect to your node over Tor for enhanced privacy, or to reach nodes on .onion addresses.

Requirements:

1. Tor must be running locally — install and start the Tor service on your machine
2. Your node must be reachable via Tor (either a .onion address or clearnet through Tor)

Install Tor:

# macOS
brew install tor && brew services start tor

# Ubuntu/Debian
sudo apt install tor && sudo systemctl start tor

# Arch
sudo pacman -S tor && sudo systemctl start tor

Configure with SOCKS5 proxy:

Add socks5Proxy to any backend config:

{
  "backend": "cln",
  "url": "http://your-node.onion:3010",
  "rune": "your-rune-token",
  "socks5Proxy": "socks5h://127.0.0.1:9050"
}

Common proxy addresses:

Service	Address
Tor daemon	socks5h://127.0.0.1:9050
Tor Browser	socks5h://127.0.0.1:9150

💡 Use socks5h:// (not socks5://) so .onion addresses are resolved through Tor, not locally.

Examples

# Check balance
/lightning

# Create invoice
/lightning invoice 1000 "Coffee payment"

# Pay Lightning Address
/lightning pay nicktee@strike.me 100

# Pay BOLT12 offer
/lightning pay lno1pg... 50

# Save & pay contact
/lightning add topher lno1pg...
/lightning pay topher 69

Files

• ~/.lightning-config.json - Backend credentials
• ~/.lightning-contacts.json - Saved contacts

Security Notes

• Never share macaroons, runes, seeds, or API keys
• Use acceptInvalidCerts only for self-signed certs on trusted networks
• Contacts file contains payment destinations only, no secrets
