Welcome to the world of blockchain data processing! In this guide, we will explore how to effectively scrape Etherscan data, analyze it, and visualize it using powerful tools. This project, developed by Elyse Lam during the USC Viterbi Data Science Bootcamp, serves as a perfect toolset for anyone interested in leveraging the Etherscan API in their programming adventures.

What You Will Need

• Python installed on your computer.
• Access to the Etherscan API and an API key.
• Basic understanding of command line interface.
• Homebrew installed on Mac for certain installations.

Installation Steps

Start by installing the Etherscan ML package and ensuring you have all dependencies in place. Follow these simple commands:

pip install etherscan-ml

wget https://tinyurl.com/etherscan-ml

If you’re on a Mac, you will also need to execute the following command:

brew install gnu-sed

How to Scrape Etherscan and Visualize Data with Gephi

Once you have installed the necessary tools, you can start scraping data from Etherscan. This process can be likened to setting up a fishing net in a river:

• The river represents the vast pool of blockchain transactions.
• Your fishing net is the scraping tool that captures all the transaction data.
• Once you have your catch, you can analyze and visualize it to see patterns and insights in the data.

For this project, you can use the following tools effectively:

• wallet-tools: Useful to check ether balances and inspect wallet transactions.
• erc20-tools: Allows access to token balances and transactions for ease of tracking specific tokens.
• ether-tools: Provides real-time ether pricing and total supply data.

Usage Examples

Here’s how you can use one of the tools to get all transactions for a token:

python3.6 all_transactions.py token_address tokenname.preprocessed

After completing the transaction data collection, you can run a formatting script:

.fix_batch.sh tokenname.preprocessed

If you wish to convert the resulting data to a CSV, run:

python3.6 convert-wallet.py tokenname.json

Troubleshooting Common Issues

While working with Etherscan and its tools, you might face some hiccups. Here’s how to tackle them:

• If you encounter issues with data formatting, make sure that you have installed Homebrew and followed the setup steps accurately.
• For any network connectivity issues, double-check your internet connection and ensure your API key is valid.
• If you get errors related to Python compatibility, ensure you are using Python 3, as many scripts are designed specifically for that version.
