1. Collection of the contract addresses. We used Google BigQuery to select all the contracts that have at least one transaction. The collection was performed on the 8th of August 2019. We used the following request (also available here: https://bigquery.cloud.google.com/savedquery/281902325312:47fd9afda3f8495184d98db6ae36a40c)

SELECT contracts.address, COUNT(1) AS tx_count
  FROM `ethereum_blockchain.contracts` AS contracts
  JOIN `ethereum_blockchain.transactions` AS transactions 
        ON (transactions.to_address = contracts.address)
  GROUP BY contracts.address
  ORDER BY tx_count DESC

2. Downloading the source code associated with the contract addresses. We used Etherscan to download the contracts (the script used for the collection is available in the folder script).
3. We filtered the contracts by identifying and removing duplicates.
