Monitor Tokens Development Tutorials, Guides & Insights

Introduction

In this tutorial, we'll learn how to track newly created tokens on the Solana blockchain. Solana uses the SPL Token Program for its token operations, which allows developers to create, transfer, and manage tokens efficiently. We will explore how to interact with Solana's RPC API and the Solana Web3.js library to monitor new token creation events.

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();

• Etherscan API: We use the tokentx action from Etherscan's API to fetch token transfer events. The API returns a list of token transactions, including newly created tokens.
• Filter for New Tokens: We filter transactions where the from address is 0x0000000000000000000000000000000000000000, indicating a token creation event. This address is used as a placeholder for the "zero address" in token contracts.
• Display Information: We log the name, symbol, and contract address of each newly created token.
