15 min readinteractiveIncludes quiz · 2 questions

Building Lightning applications opens up infinite possibilities for programmable money. From micropayments to streaming payments, Lightning enables entirely new economic models.

Common Lightning app patterns:

  • •Micropayments: Pay-per-use services (streaming, APIs)
  • •Streaming Payments: Continuous payment flows
  • •Marketplaces: Peer-to-peer trading platforms
  • •Gaming: In-game microtransactions
  • •Content Monetization: Pay-per-view, tipping
  • •IoT Payments: Machine-to-machine transactions

Development approaches:

  • •LDK Integration: Rust-based Lightning library
  • •LND gRPC: Direct communication with LND node
  • •c-lightning JSON-RPC: RESTful API interface
  • •Lightning libraries: JavaScript, Python, Go implementations

Key concepts:

  • •Invoice Generation: Create payment requests
  • •Payment Handling: Receive and verify payments
  • •Webhook Integration: Real-time payment notifications
  • •Error Handling: Manage failed payments gracefully
Lightning Invoice Generation
// Node.js Lightning invoice example
const { createInvoice, getInvoice } = require('lightning-client');

async function createLightningInvoice(amount, memo) {
    try {
        const invoice = await createInvoice({
            value: amount * 100000000, // Convert to satoshis
            memo: memo,
            expiry: 3600, // 1 hour expiry
            private: false
        });
        
        console.log('Invoice created:', invoice.payment_request);
        return invoice;
    } catch (error) {
        console.error('Invoice creation failed:', error);
        throw error;
    }
}

// Usage
createLightningInvoice(0.01, 'Coffee payment');
