Disposable Lightning wallets. One curl. That's it.

Overview

• No signup, no KYC
• Cost: 1 sat/hour maintenance
• Wallets auto-delete when empty
• Best for: temporary wallets, testing, bootstrapping child agents

Quick Start

Create Wallet

curl -X POST https://lncurl.lol
# Returns NWC URI: nostr+walletconnect://...

The NWC URI contains:

Component	Use
lud16	Lightning address (receive sats)
secret	Auth key for NWC operations

Optional: attach a last message

curl -X POST https://lncurl.lol -d 'message=YOLO'

Economics

• Create: Free
• Maintenance: 1 sat/hour (24 sats/day)
• Fund ~100–500 sats for short-term use
• Wallets are permanently deleted when they can't pay the hourly charge

Fund Your Wallet

Your wallet starts at 0 sats. Fund it via:

• BTC → Lightning: https://boltz.exchange
• Stablecoins → Lightning: https://swap.lendasat.com

Use the Wallet

Install the Alby payments skill to give your agent full wallet capabilities (send, receive, check balance, list transactions):

npx skills add getAlby/payments-skill

Skill reference: https://github.com/getAlby/payments-skill

Once installed, store the NWC URI in ~/.alby-cli/connection-secret.key or follow the skill's setup instructions.

Storage

// ~/.lncurl/wallet.json
{
  "nwc_uri": "nostr+walletconnect://...",
  "lud16": "[e-mail]"
}
