Environment Variables

BERRYPAY_SEED      # 64-char hex seed (overrides config file)
BERRYPAY_RPC_URL   # RPC node URL
BERRYPAY_WS_URL    # WebSocket URL

Payment Processor

Accept payments with auto-generated ephemeral addresses:

# Create a charge with webhook
berrypay charge create 0.5 --webhook http://localhost:3000/callback

# With metadata for your webhook
berrypay charge create 0.5 \
  --webhook http://localhost:3000/callback \
  --metadata '{"orderId": "123"}'

# With QR code image
berrypay charge create 0.5 --qr --output /tmp/payment.png

# Check status (auto-receives and sweeps if paid)
berrypay charge status chg_abc123

# List all charges
berrypay charge list

# Check listener status
berrypay charge listener

# Stop listener
berrypay charge stop

Flow

1. charge create 1.0  →  Ephemeral address generated, listener auto-starts
2. Customer pays      →  WebSocket detects payment
3. Auto-receive       →  Pending blocks received
4. Auto-sweep         →  Funds sent to main wallet (index 0)
5. Webhook called     →  Your server notified with charge details
6. Auto-stop          →  Listener stops when no active charges

Programmatic Usage

import { BerryPayWallet, PaymentProcessor } from 'berrypay';

const wallet = new BerryPayWallet({ seed: process.env.BERRYPAY_SEED });

// Send
await wallet.send('nano_1...', BerryPayWallet.nanoToRaw('0.1'));

// Payment processor
const processor = new PaymentProcessor({ wallet, autoSweep: true });
processor.on('charge:completed', (charge) => console.log('Paid!', charge.id));
processor.on('charge:swept', ({ hash }) => console.log('Swept:', hash));
await processor.start();

const charge = await processor.createCharge({
  amountNano: '1.0',
  webhookUrl: 'http://localhost:3000/callback',
  metadata: { orderId: '123' }
});
// charge.address - send payment here
