Blockchain Development Programming Tutorials, Guides & Best Practices

• Token Program: Manages and interacts with tokens on the Solana blockchain. It supports minting, transferring, burning, and freezing tokens.
• Associated Token Account Program: Creates and manages associated token accounts for users.
• Memo Program: Allows developers to attach arbitrary data to transactions.
• Token Swap Program: Enables token swapping functionalities similar to those found in decentralized exchanges (DEXs).

Let's start by creating a new project using the Anchor framework.

Step 3: Track a Specific Solana Address

We'll now write a function to track a specific Solana address and log new trades:

const solanaWeb3 = require('@solana/web3.js');

// Connect to the Solana Devnet
const connection = new solanaWeb3.Connection(
  solanaWeb3.clusterApiUrl('devnet'),
  'confirmed'
);

console.log('Connected to Solana Devnet');

This code establishes a connection to the Solana Devnet, allowing us to interact with the network for development purposes.

Next, let's fetch the balance of a specific wallet address. Add the following function to your index.js file:

async function getWalletBalance(walletAddress) {
  try {
    const publicKey = new solanaWeb3.PublicKey(walletAddress);
    const balance = await connection.getBalance(publicKey);
    console.log(`Wallet Balance: ${balance / solanaWeb3.LAMPORTS_PER_SOL} SOL`);
  } catch (error) {
    console.error('Error fetching wallet balance:', error);
  }
}

// Replace with your Solana wallet address
const walletAddress = 'YourWalletAddressHere';
getWalletBalance(walletAddress);

Use npm to install the Anchor CLI:

   npm install -g @project-serum/anchor-cli
