Self-custodial Lightning wallet for AI agents, built by MoneyDevKit. One command to init. All output is JSON.
Source: @moneydevkit/agent-wallet on npm · GitHub
Security & Transparency
This skill runs @moneydevkit/agent-wallet — an npm package published by MoneyDevKit. What it does:
- Generates and stores a BIP39 mnemonic at
~/.mdk-wallet/config.json— this IS your private key. Treat it like a password. - Runs a local daemon on
localhost:3456— HTTP server for wallet operations. Binds to localhost only (not externally accessible). - Connects outbound to MDK's Lightning infrastructure.
- Persists payment history to
~/.mdk-wallet/.
No data is sent to external servers beyond standard Lightning protocol operations. You can verify this by inspecting the source code or the published npm tarball.
Recommended: Pin a version (npx @moneydevkit/agent-wallet@0.11.0) in production.
Quick Start
# Initialize wallet (generates mnemonic)
npx @moneydevkit/agent-wallet init
# Get balance
npx @moneydevkit/agent-wallet balance
# Create invoice
npx @moneydevkit/agent-wallet receive 1000
# Pay someone
npx @moneydevkit/agent-wallet send user@getalby.com 500
How It Works
The CLI automatically starts a daemon on first command. The daemon:
- Runs a local HTTP server on
localhost:3456 - Connects to MDK's Lightning infrastructure
- Polls for incoming payments every 30 seconds
- Persists payment history to
~/.mdk-wallet/
No webhook endpoint needed — the daemon handles everything locally.
Setup
First-time initialization
npx @moneydevkit/agent-wallet init
This command:
- Generates a BIP39 mnemonic — 12-word seed phrase that IS your wallet
- Creates config at
~/.mdk-wallet/config.json - Derives a walletId — deterministic 8-char hex ID from your mnemonic
- Starts the daemon — local Lightning node on port 3456
The wallet is ready immediately. No API keys, no signup, no accounts. The agent holds its own keys.
View existing config
npx @moneydevkit/agent-wallet init --show
Returns { "mnemonic": "...", "network": "mainnet", "walletId": "..." }.
Note: init will refuse to overwrite an existing wallet. To reinitialize:
npx @moneydevkit/agent-wallet stop
rm -rf ~/.mdk-wallet # WARNING: backup mnemonic first!
npx @moneydevkit/agent-wallet init
Commands
All commands return JSON on stdout. Exit 0 on success, 1 on error.
| Command | Description |
|---|---|
init |
Generate mnemonic, create config |
init --show |
Show config (mnemonic redacted) |
start |
Start the daemon |
balance |
Get balance in sats |
receive <amount> |
Generate invoice |
receive |
Generate variable-amount invoice |
receive <amount> --description "..." |
Invoice with custom description |
receive-bolt12 |
Generate a BOLT12 offer (variable amount, reusable) |
send <destination> [amount] |
Pay bolt11, bolt12, lnurl, or lightning address |

status |
Check if daemon is running |
stop |

Balance
npx @moneydevkit/agent-wallet balance
→ { "balance_sats": 3825 }
Receive (generate invoice)
# Fixed amount
npx @moneydevkit/agent-wallet receive 1000
# Variable amount (payer chooses)
npx @moneydevkit/agent-wallet receive
# With description
npx @moneydevkit/agent-wallet receive 1000 --description "payment for service"
→ { "invoice": "lnbc...", "payment_hash": "...", "expires_at": "..." }
Receive BOLT12 Offer
npx @moneydevkit/agent-wallet receive-bolt12
→ { "offer": "lno1..." }
BOLT12 offers are reusable and don't expire — share one offer and receive unlimited payments to it. Unlike BOLT11 invoices, the payer chooses the amount.
Send
npx @moneydevkit/agent-wallet send <destination> [amount_sats]
Destination auto-detection:
- bolt11 invoice:
lnbc10n1...(amount encoded, no arg needed) - bolt12 offer:
lno1... - lightning address:
user@example.com - LNURL:
lnurl1...
For lightning addresses and LNURL, amount is required:
npx @moneydevkit/agent-wallet send user@getalby.com 500
Payment History
npx @moneydevkit/agent-wallet payments
→ { "payments": [{ "paymentHash": "...", "amountSats": 1000, "direction": "inbound"|"outbound", "timestamp": ..., "destination": "..." }] }
Upgrading
# Stop the running daemon
npx @moneydevkit/agent-wallet stop
# Run with @latest to pull the newest version
npx @moneydevkit/agent-wallet@latest start
Your wallet config and payment history in ~/.mdk-wallet/ are preserved across upgrades.
Usage Notes
- Denomination: use ₿ prefix with sats (e.g. ₿1,000 not "1,000 sats")
- Self-custodial: the mnemonic IS the wallet. Back it up. Lose it, lose funds.
- Daemon: runs a local Lightning node on
:3456. Auto-starts, persists to disk. - Agent-to-agent payments: any agent with this wallet can pay any other agent's invoice or lightning address.
