Payment Gateway Crypto

A simple crypto payment gateway using ethers.js. This package allows you to handle payments, check balances, and collect fees using Ethereum smart contracts.

Installation

You can install this package using npm:

npm install payment-gateway-crypto

Usage

Importing the Module

You can import the handlePayment function using ES6 module syntax:

import { handlePayment } from 'payment-gateway-crypto';

Or using CommonJS syntax:

const { handlePayment } = require('payment-gateway-crypto');

Using the handlePayment Function

The handlePayment function allows you to make payments to a specified Ethereum address. Here's an example of how to use it:

import { handlePayment } from 'payment-gateway-crypto';

const amount = 0.001; // Example amount in Ether
const address = '0x1F85a21033Da743136C1808D635e8679221418d1'; // Receiver's wallet address
const netwrok = 'POLzk'; //'POLzk' for Polygon zkEVM and 'BASE' for Base Sepolia network
handlePayment(amount, address, network).then(() => {
    console.log('Payment successful');
}).catch(error => {
    console.error('Payment failed', error);
});

handlePayment(amount, address)

• amount (number): The amount of Ether to send.
• address (string): The recipient's Ethereum address.
• network (string): 'POLzk' for Polygon zkEVM CARDONA Testnet and 'BASE' for Base Sepolia network

This function sends the specified amount of Ether to the given address using the connected Ethereum wallet.

Example

Here is a complete example of a simple React component that uses the handlePayment function:

import React from 'react';
import { handlePayment } from 'payment-gateway-crypto';

const PaymentComponent = ({ amount }) => {
    const address = '0x1F85a21033Da743136C1808D635e8679221418d1';
    const network = 'BASE';
    const handleButtonClick = async () => {
        try {
           const tx = await handlePayment(amount, address, network);
            console.log('Payment successful', tx);
        } catch (error) {
            console.error('Payment failed', error);
        }
    };

    return (
        <div>
            <h1>Pay {amount} ETH</h1>
            <button onClick={handleButtonClick}>Confirm</button>
        </div>
    );
};

export default PaymentComponent;
