Blockchain Development Programming Tutorials, Guides & Best Practices

To follow along with this tutorial, you’ll need:

• Node.js installed on your machine.
• A basic understanding of JavaScript.
• An Etherscan API key (explained below).
• Familiarity with Ethers.js for blockchain interaction.

const axios = require('axios');

// Replace this with your actual Etherscan API key
const apiKey = 'YOUR_ETHERSCAN_API_KEY';

// Replace this with the transaction hash you want to query
const transactionHash = '0xYourTransactionHash';

// Etherscan API URL to fetch transaction details
const url = `https://api.etherscan.io/api?module=proxy&action=eth_getTransactionByHash&txhash=${transactionHash}&apikey=${apiKey}`;

async function getTransactionDetails() {
  try {
    // Make the API request to Etherscan
    const response = await axios.get(url);
    const transactionDetails = response.data.result;

    // Log the transaction details
    console.log('Transaction Details:', transactionDetails);
  } catch (error) {
    console.error('Error fetching transaction details:', error);
  }
}

// Call the function to get the transaction details
getTransactionDetails();

• Replace 'YOUR_ETHERSCAN_API_KEY' with your actual Etherscan API key.
• Replace '0xYourTransactionHash' with the transaction hash you want to query.
• This script uses the eth_getTransactionByHash endpoint to fetch transaction details, such as gas price, block number, and sender/receiver addresses.

> Important: Keep your private key secure. Never share it publicly or commit it to version control. For better security, consider using environment variables to store sensitive information like private keys.

Once your script is set up, run it from the command line:

Token burns are typically done to increase scarcity, and scarcity can lead to a higher token value if demand remains the same or increases. The basic principle of supply and demand comes into play: when the supply of an asset is reduced, it becomes more valuable (assuming demand holds steady).

Many projects use token burns strategically, announcing burn events in advance to generate interest in the project and potentially boost the value of the remaining tokens.

Prerequisites

• Node.js and npm installed on your system.
• Basic knowledge of JavaScript and Solana.
• A Solana wallet address you wish to track.
