Crypto Payment Gateway: Accepting Digital Currency Payments

Accepting cryptocurrency payments opens your business to a global customer base.

Payment Architecture

interface CryptoPayment {
  id: string; orderId: string; amount: number; chain: string
  status: 'pending' | 'confirming' | 'confirmed' | 'failed'
  confirmations: number; requiredConfirmations: number
}

Generating Payment Addresses

import { ethers } from 'ethers'
class PaymentAddressManager {
  private masterWallet = new ethers.Wallet(process.env.MASTER_PRIVATE_KEY!)
  generatePaymentAddress(orderId: string): string {
    const path = `m/44/60'/0'/0/${orderId}`
    const wallet = ethers.HDNodeWallet.fromMnemonic(this.masterWallet.mnemonic, path)
    return wallet.address
  }
}

Payment Monitoring

Watch for incoming transactions, track confirmations, and auto-fulfill orders when threshold is met.
