    Phantom Wallet DApp Integration Guide
    Phantom Wallet is a popular digital wallet that allows users to store, send, and receive Solana-based tokens. In this article, we will explore the step-by-step process of integrating Phantom Wallet with a DApp (Decentralized Application) on the Solana blockchain.
    To get started, you’ll need to have a basic understanding of blockchain technology, Solana development, and JavaScript programming.

    Introduction to Phantom Wallet
    Phantom Wallet is a non-custodial wallet, which means that users have full control over their private keys and funds. It supports multiple Solana-based tokens, including SOL and SRM. The wallet is available as a browser extension and a mobile app.
    When integrating Phantom Wallet with a DApp, you’ll need to use the Phantom Wallet API.

    Setting Up Phantom Wallet
    To set up Phantom Wallet, follow these steps:

    1. Install the Phantom Wallet browser extension or mobile app.
    2. Create a new wallet or import an existing one.
    3. Fund your wallet with some SOL or other Solana-based tokens.

    Connecting to Phantom Wallet
    To connect to Phantom Wallet from your DApp, you’ll need to use the Phantom Wallet API. Here are the steps:

    1. Import the Phantom Wallet API library in your JavaScript code.
    2. Use the `connect` method to establish a connection with the user’s Phantom Wallet.
    3. Request the user’s permission to access their wallet.

    The following are some of the most commonly used Phantom Wallet API methods:

    Method Description
    `connect` Establishes a connection with the user’s Phantom Wallet.
    `disconnect` Disconnects from the user’s Phantom Wallet.
    `getBalance` Retrieves the user’s SOL balance.
    `getAccounts` Retrieves the user’s Solana accounts.
    `signTransaction` Signs a transaction using the user’s private key.

    Integration Example

// Import the Phantom Wallet API library
const { PhantomWallet } = require('phantom-wallet');

// Create a new instance of the Phantom Wallet API
const phantom = new PhantomWallet();

// Connect to the user's Phantom Wallet
phantom.connect().then(() => {
  console.log('Connected to Phantom Wallet');
}).catch((error) => {
  console.error('Error connecting to Phantom Wallet:', error);
});

// Request the user's permission to access their wallet
phantom.requestPermission().then(() => {
  console.log('Permission granted');
}).catch((error) => {
  console.error('Error requesting permission:', error);
});

// Retrieve the user's SOL balance
phantom.getBalance().then((balance) => {
  console.log('SOL balance:', balance);
}).catch((error) => {
  console.error('Error retrieving balance:', error);
});
