Smart Contracts Corpus Repository: Source Code and Metrics.

Many empirical software engineering studies show that there is a great need for repositories where code is acquired, filtered and classified.<br> During the last few years, Ethereum block explorer services have emerged as a popular project to explore and search Ethereum blockchain data such as transactions, addresses, tokens, smart-contracts' source code, prices and other activities taking place on Ethereum blockchain.<br> Despite the availability of this kind of services, retrieving specific information useful to empirical software engineering studies, such as the study of smart-contracts' software metrics, might be a tedious task that requires different sub-tasks such as searching specific transactions in a block, parsing files in HTML format and filtering the smart-contracts to remove duplicated code or unused smart-contracts.<br> Smac-Corpus aims to create a smart-contracts' repository where smart contracts data (source code, ABI and byte code) are freely and immediately available and also classified based on software metrics identified in the scientific literature.

诸多经验性软件工程研究均表明，业界亟需可对代码进行获取、筛选与分类的代码存储库。
近年来，以太坊区块浏览器服务已成为热门项目，用于探索与检索以太坊区块链上的各类数据，涵盖交易、地址、代币、智能合约（smart-contracts）源代码、价格及其他链上活动。
尽管此类服务已投入使用，但针对经验性软件工程研究所需的特定信息（如智能合约软件度量研究）开展检索，往往是一项繁琐的工作，需完成多项子任务，例如在区块中检索特定交易、解析HTML格式文件，以及筛选智能合约以剔除重复代码或未使用的智能合约。
Smac-Corpus旨在构建一个智能合约仓库，可免费且即时提供智能合约数据（源代码、应用二进制接口（ABI）与字节码），并基于科学文献中已确认的软件度量标准对其进行分类。
