This repository contains 47,398 smart contracts extracted from the Ethereum network.
SmartBugs was used to analyze this dataset. The results are available at: https://github.com/smartbugs/smartbugs-results For more details on the analysis, please see the ICSE 2020 paper.

- 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- 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). - We filtered the contracts by identifying and removing duplicates.
