How to Retrieve Top Accounts Data from Etherscan

What will you learn?

In this tutorial, you will delve into the process of extracting data about top accounts from using web scraping techniques with Python. By the end of this guide, you will have a clear understanding of how to programmatically access and download valuable information from the Ethereum blockchain explorer.

Introduction to Problem and Solution serves as a prominent platform for exploring the Ethereum blockchain, offering detailed insights into transactions, addresses, and more. However, in scenarios where direct API access is not provided, web scraping emerges as a powerful solution to automate data retrieval from websites. In this context, we aim to extract data pertaining to top accounts listed on by leveraging Python’s web scraping capabilities.


import requests
from bs4 import BeautifulSoup

def scrape_top_accounts():
    # URL of the page where top accounts are listed
    url = ""

    # Make a request to fetch the page content
    response = requests.get(url)

    # Initialize BeautifulSoup with fetched content and lxml parser
    soup = BeautifulSoup(response.text, 'lxml')

    # Find all table rows in the first table (assuming it's our target table)
    rows = soup.find('table').find_all('tr')[1:]  # Skipping header row

    for row in rows:
        rank = row.find_all('td')[0].text.strip()
        address = row.find_all('td')[1].text.strip()
        balance = row.find_all('td')[2].text.strip()

        print(f"Rank: {rank}, Address: {address}, Balance: {balance}")

The provided code snippet demonstrates the implementation of web scraping techniques using Python libraries such as requests for fetching web pages and BeautifulSoup for parsing HTML content. The scrape_top_accounts function targets’s top accounts page, retrieves its HTML content through a GET request, parses the content to extract relevant information from table entries representing account details like rank, address, and balance.

Key steps involved: – Utilizing requests for fetching webpage content. – Employing BeautifulSoup for HTML parsing. – Extracting specific elements based on their position within the HTML document structure.

This approach assumes familiarity with the website’s HTML markup structure; any changes in this structure may necessitate script modifications.

  1. How can I install necessary libraries?

  2. You can install required libraries using pip:

  3. pip install requests beautifulsoup4 lxml

  5. What if I encounter a 403 Forbidden error?

  6. Consider setting headers in your request or utilizing sessions with cookies to bypass restrictions imposed by certain websites.

  7. Can I scrape any site?

  8. Before proceeding with scraping, ensure compliance with a website�s terms of service or robots.txt file to avoid potential legal issues related to unauthorized data extraction.

  9. How do I handle dynamic JavaScript-loaded data?

  10. For websites employing dynamic JavaScript frameworks like Angular or ReactJS, consider using tools like Selenium or Puppeteer instead of BeautifulSoup for effective data retrieval.

  11. Is there rate limiting concerns when scraping?

  12. Websites may enforce limits on request frequencies; adhere to these limitations by incorporating pauses (e.g., time.sleep()) between successive requests if required.

  13. Can my IP be blocked while scraping?

  14. Excessive rapid requests could lead to IP blocking; employ proxies or VPNs if necessary while respecting ethical guidelines set by websites.

  15. How do I deal with pagination?

  16. Adjust your scraper logic to navigate through multiple pages by identifying �next� button links or modifying URLs based on discernible patterns present in pagination structures.

  17. Can I save scraped data into files?

  18. Certainly! Utilize Python’s file handling functionalities (e.g., open, write) or explore modules like pandas for structured storage such as CSV files.

  19. Are there alternatives to BeautifulSoup for parsing HTML in Python?

  20. Yes! Consider alternatives like directly using lxml library or opting for Scrapy framework that offers advanced features suitable for larger-scale projects including pipelines and middlewares support.


Web scraping serves as an invaluable tool when accessing data without direct API availability�as exemplified in this tutorial focusing on retrieving top Ethereum account balances from While grasping fundamental concepts is crucial initially, practical applications might demand addressing additional complexities such as managing AJAX calls or session states across multiple pages effectively.
