Complete guide to integrating X402 payment protocol into your applications

Protocol Endpoint: x402b.netlify.app

## PROTOCOL OVERVIEW

### What is X402?

X402 is an open-standard payment protocol on Solana that enables infinite transaction layers where developers build and only verified nodes process payments.

### Core Principles

Open standards, verified node processing, infinite scalability, developer-first architecture, cross-platform compatibility.

### Protocol Endpoint

Access the protocol at x402b.netlify.app - your gateway to infinite payment corridors.

## GETTING STARTED

### Installation

npm install @x402/sdk
# or
yarn add @x402/sdk

### Basic Setup

import { X402Client } from "@x402/sdk";

const client = new X402Client({
  network: "mainnet",
  endpoint: "https://x402b.netlify.app/api",
  apiKey: process.env.X402_API_KEY
});

## API REFERENCE

### Initialize Payment

const payment = await client.initializePayment({
  amount: "1.0",
  recipient: "0x...",
  metadata: { orderId: "12345" }
});

### Process Transaction

const result = await client.processTransaction({
  paymentId: payment.id,
  verifiedNode: true
});

## VERIFIED NODES

### Node Requirements

Verified nodes must maintain 99.9% uptime, process transactions within 2 seconds, and pass security audits every quarter.

### Becoming a Verified Node

Apply through the developer portal, complete security audit, stake minimum collateral, and maintain performance metrics.
