Setup

Prerequisites

• Alby Hub account
• NWC (Nostr Wallet Connect) URL

Installation

Configuration

Add to openclaw.json:

json

{
  "env": {
    "ALBY_NWC_URL": "nostr+walletconnect://..."

⚠️ Security

Your NWC URL contains your wallet's private key. Anyone with this URL can spend your funds.

• NEVER commit it to git or share it publicly
• ALWAYS set spending limits in Alby Hub before use
• Store it only in openclaw.json (not in code files)
• Rotate the NWC URL immediately if you suspect it was leaked

Gotchas

• Always specify amount for zero-amount invoices
• Use result.invoice, not result.payment_request
• Set spending limits in Alby Hub
