The Myaza POS SDK is a production-grade JavaScript library that lets merchants accept cryptocurrency payments without requiring webhook setup or Web3 knowledge. It works with React, Next.js, Vue, Svelte, and plain JavaScript.

​
How It Works

The SDK handles the entire payment flow:
  1. Initialize the SDK with your merchant ID
  2. Call checkout() with a fiat amount
  3. The SDK opens a payment modal where the customer selects a chain and token
  4. The SDK generates a deposit address and QR code
  5. It polls for on-chain confirmation automatically
  6. Your app receives events as the payment progresses

Quick Example

import { MyazaPOS } from '@myazahq/pos-sdk';

const pos = new MyazaPOS({
  merchantId: 'your-merchant-id',
  isSandbox: true,
});

await pos.init();

pos.on('payment.confirmed', (event) => {
  console.log('Payment confirmed!', event.session);
});

await pos.checkout({ amount: 25.00, currency: 'USD' });
Always verify payment status from your server before fulfilling an order. Never trust client-side events alone.
