Pay from anywhere from any solana-vm based network!

## Overview

SVM-Pay is a payment solution for SVM networks (Solana, Sonic SVM, Eclipse, s00n) that enables developers to easily integrate payment functionality into their applications. Inspired by Solana Pay, SVM-Pay extends the concept to work across all SVM networks with a one-click integration approach for developers.

## Features

- **Cross-Network Compatibility**: Support for Solana, Sonic SVM, Eclipse, and s00n networks
- **Simple Integration**: One-click integration for developers
- **Comprehensive SDK**: JavaScript/TypeScript SDK with React, Vue, and Angular components
- **Mobile Support**: iOS and Android SDK for mobile applications
- **No Fees**: SVM-Pay itself charges no fees (only standard network transaction fees apply)
- **Secure**: Built with security best practices for blockchain payments
- **Flexible**: Support for different payment scenarios (e-commerce, point-of-sale, subscriptions)

## Installation

```bash
npm install svm-pay
```

## Basic Usage

```javascript
import { SVMPay } from 'svm-pay';

// Initialize the SDK
const svmPay = new SVMPay({
  defaultNetwork: 'solana', // 'solana', 'sonic', 'eclipse', or 'soon'
});

// Create a payment URL
const url = svmPay.createTransferUrl(
  'YOUR_WALLET_ADDRESS',
  '1.0', // Amount
  {
    label: 'Your Store',
    message: 'Payment for Order #123',
    references: ['order-123']
  }
);

console.log(url);
// Output: solana:YOUR_WALLET_ADDRESS?amount=1.0&label=Your%20Store&message=Payment%20for%20Order%20%23123&reference=order-123

// CLI Integration - access CLI functionality programmatically
// Check wallet balance (requires CLI setup)
svmPay.checkWalletBalance()
  .then(balance => console.log('Wallet balance:', balance))
  .catch(error => console.error('Balance check failed:', error));
```

## CLI Tool

SVM-Pay includes a built-in CLI tool for managing payments:

```bash
# Install globally
npm install -g svm-pay

# Setup configuration
svm-pay setup -k <your-private-key> -a <your-api-key>

# Check wallet balance
svm-pay balance

# Check API usage
svm-pay usage

# Make a payment
svm-pay pay -a 0.1 -r "API usage payment"

# View payment history
svm-pay history
```

See [CLI Integration](CLI-INTEGRATION.md) for complete CLI documentation.
```
