Etherscan Api Development Tutorials, Guides & Insights

We will use Ethers.js to interact with the Ethereum blockchain and Axios to make HTTP requests to the Etherscan API.

npm install ethers
npm install axios

Once you have written the script, run it from your terminal:

node etherscanBalance.js

We will use Etherscan's API to fetch information about newly created tokens. Add the following function to your index.js file:

const axios = require('axios');

// Replace with your Etherscan API key
const ETHERSCAN_API_KEY = 'YOUR_ETHERSCAN_API_KEY';

async function getNewTokens() {
  try {
    const url = `https://api.etherscan.io/api?module=account&action=tokentx&address=0x0&startblock=0&endblock=99999999&sort=asc&apikey=${ETHERSCAN_API_KEY}`;
    const response = await axios.get(url);

    if (response.data.status === '1') {
      const transactions = response.data.result;
      const newTokens = transactions.filter(tx => tx.tokenSymbol && tx.tokenName && tx.from === '0x0000000000000000000000000000000000000000');

      console.log('Newly Created Tokens:');
      newTokens.forEach(token => {
        console.log(`- Token Name: ${token.tokenName}`);
        console.log(`  Token Symbol: ${token.tokenSymbol}`);
        console.log(`  Token Contract Address: ${token.contractAddress}`);
      });
    } else {
      console.error('Error fetching token transactions:', response.data.message);
    }
  } catch (error) {
    console.error('Error:', error);
  }
}

getNewTokens();
