LNBits Wallet wtih QR Code

Manage LNbits Lightning Wallet (Balance, Pay, Invoice)

LNbits Wallet Manager

Enable the assistant to safely and effectively manage an LNbits Lightning Network wallet.

🛑 CRITICAL PROTOCOLS 🛑

1. NEVER Expose Secrets: Do NOT display Admin Keys, User IDs, or Wallet IDs.
2. Explicit Confirmation: You MUST ask for "Yes/No" confirmation before paying.
   • Format: "I am about to send [Amount] sats to [Memo/Dest]. Proceed? (y/n)"
3. Check Balance First: Always call balance before pay to prevent errors.
4. ALWAYS Include Invoice + QR: When generating an invoice, you MUST: (a) show the payment_request text for copying, and (b) output MEDIA: followed by the qr_file path on ONE line. NEVER skip this.

Usage

0. Setup / Create Wallet

If the user does not have an LNbits wallet, you can create one for them on the demo server.

python3 {baseDir}/scripts/lnbits_cli.py create --name "My Wallet"

Action:

1. Run the command. The CLI prints JSON containing adminkey and base_url to stdout (visible in the terminal).
2. NEVER Expose Secrets (applies here): Do NOT repeat, quote, or display the adminkey or any secret from the output in your chat response. The user sees the command output in their terminal; that is the only place the key should appear.
3. Instruct the user in plain language only, e.g.:

   "A new wallet was created. The command output above contains your adminkey and base_url. Copy those values from the terminal and add them to your configuration or .env as LNBITS_API_KEY and LNBITS_BASE_URL. Do not paste the adminkey here or in any chat."

1. Check Balance

Get the current wallet balance in Satoshis.

python3 {baseDir}/scripts/lnbits_cli.py balance

2. Create Invoice (Receive)

Generate a Bolt11 invoice to receive funds. QR code is always included by default.

• amount: Amount in Satoshis (Integer).
• memo: Optional description.
• --no-qr: Skip QR code generation (if not needed).

# Invoice with QR code (default)
python3 {baseDir}/scripts/lnbits_cli.py invoice --amount 1000 --memo "Pizza"

# Invoice without QR code
python3 {baseDir}/scripts/lnbits_cli.py invoice --amount 1000 --memo "Pizza" --no-qr

⚠️ MANDATORY RESPONSE FORMAT: When generating an invoice, your response MUST include:

1. Invoice text for copying: Show the full payment_request string so user can copy it
2. QR code image: Output MEDIA: followed by the qr_file path on ONE line

EXACT FORMAT (follow precisely):

Here is your 100 sat invoice:

lnbc1u1p5abc123...

MEDIA:./clawd/.lnbits_qr/invoice_xxx.png

CRITICAL: The MEDIA: and file path MUST be on the SAME LINE. This sends the QR code image to the user.

2b. Generate QR Code from Existing Invoice

Convert any Bolt11 string to a QR code image file.

python3 {baseDir}/scripts/lnbits_cli.py qr <bolt11_string>

Returns: {"qr_file": "./.lnbits_qr/invoice_xxx.png", "bolt11": "..."}

3. Pay Invoice (Send)

⚠️ REQUIRES CONFIRMATION: Decode first, verify balance, ask user, then execute.

# Step 1: Decode to verify amount/memo
python3 {baseDir}/scripts/lnbits_cli.py decode <bolt11_string>

# Step 2: Pay (Only after user CONFIRMS)
python3 {baseDir}/scripts/lnbits_cli.py pay <bolt11_string>

Error Handling

If the CLI returns a JSON error (e.g., {"error": "Insufficient funds"}), summarize it clearly for the user. Do not show raw stack traces.
