🛑 Critical Protocols for Safe Usage 🛑

To ensure secure and responsible handling of your LNbits wallet, this skill enforces strict protocols:

1. NEVER Expose Secrets: The assistant is programmed to NEVER display Admin Keys, User IDs, or Wallet IDs in chat. Credentials are handled via environment variables.
2. Explicit Payment Confirmation: The assistant MUST ask for "Yes/No" confirmation before sending any payment.
   • Confirmation Format: "I am about to send [Amount] sats to [Memo/Destination]. Proceed? (y/n)"
3. Balance Check Before Pay: The assistant will always check your wallet balance before attempting to pay an invoice to prevent failed transactions.
4. Invoice + QR Output: When generating an invoice, the assistant will ALWAYS provide:
   • The payment_request text string for easy copying.
   • An IMAGE: link to the generated QR code file on a single line, allowing direct display of the QR code.

Installation

This skill requires the qrcode[pil] Python library.

1. Install ClawHub CLI:

   npm i -g clawhub
   

2. Install the Skill:

   clawhub install lnbits
   

Configuration

The skill uses environment variables for LNbits API credentials. It's recommended to add these to your OpenClaw configuration or your agent's .env file.

• LNBITS_BASE_URL: The base URL of your LNbits instance (e.g., https://legend.lnbits.com or your self-hosted URL).
• LNBITS_API_KEY: Your LNbits wallet's Admin Key.

Example .env entries:

export LNBITS_BASE_URL=https://legend.lnbits.com
export LNBITS_API_KEY=YOUR_ADMIN_KEY_HERE

Usage Examples

Here's how you can use the lnbits skill with your OpenClaw assistant:

0. Setup / Create Wallet

If you don't have an LNbits wallet, you can create one (defaults to the demo server for ease of setup):

(User): Create a new lnbits wallet named "My OpenClaw Wallet"

The create command prints your new adminkey and base_url in the terminal output. Copy those from the command output and save them securely in your environment variables (e.g. .env). The assistant will not repeat or display the adminkey in chat.

1. Check Balance

Ask your assistant for the current balance:

(User): What's my lnbits balance?

2. Create Invoice (Receive Funds)

Generate an invoice for receiving funds:

(User): Create an invoice for 5000 sats for "Coffee"

The assistant will provide the Bolt11 invoice string and a QR code image.

2b. Generate QR Code from Existing Invoice

If you have a Bolt11 string and need a QR code:

(User): Generate a QR code for this invoice: lnbc1u1p...

3. Pay Invoice (Send Funds)

To pay an invoice, the assistant will first decode it and then ask for confirmation:

(User): Pay this invoice: lnbc1u1p...

The assistant will then prompt: "I am about to send [Amount] sats to [Memo/Dest]. Proceed? (y/n)"

Error Handling

The skill is designed to catch and summarize API errors from LNbits, providing clear feedback to the user without exposing raw technical details or stack traces.
