Generate Nano QR Code

Generates a terminal-friendly ASCII QR code for a Nano address, optionally including an amount.

CLI Usage

Basic QR (address only)

npx -y xno-skills qr nano_1abc123...

QR with amount (in XNO, decimal)

npx -y xno-skills qr nano_1abc123... --amount 1.5

JSON output (for scripts)

npx -y xno-skills qr nano_1abc123... --amount 1.5 --json

Returns:

• content: the canonical nano: URI (nano:<address>?amount=<raw>)
• qr: the ASCII QR block

CRITICAL INSTRUCTION FOR AGENTS regarding truncation: AI agents often have their stdout streams truncated (e.g., <truncated 14 lines>). If you need to print a QR code to the user, DO NOT run the command normally and paste the truncated output. Instead, either:

1. Run with --json and explicitly parse out the "qr" field (which contains the full string).
2. Pipe the output to a temporary file (> /tmp/qr.txt) and use your file-reading tool (e.g., view_file or cat) to read the complete string without truncation, then present it to the user.

Notes

• The CLI validates the address before generating the QR.
• The --amount value is interpreted as XNO (Nano), not raw.

Top-Up Requests

Use this when the user needs to receive XNO (fund their own wallet):

• If they want an easy “fund this address” QR, generate an address-only QR.
• If the user wants a specific amount, generate a QR with --amount; the resulting nano: URI includes the raw amount parameter.

In interactive flows, ask for:

• The receiving address (or confirm it).
• Optional amount in XNO.

If the user asks to send XNO “to the agent” or “to you”, initialize or import a wallet via the MCP server (mcp-wallet skill) and generate a QR code for its active address. Remember that you must subsequently call wallet_receive from the mcp-wallet skill to actually pocket the funds once they send them.
