Sourcify (sourcify.dev) is a robust Solidity source code verification service designed for Ethereum smart contracts, emphasizing transparency and accessibility as a public good infrastructure. Unlike traditional verification services, Sourcify utilizes the Solidity metadata file for full contract verification, offering key components such as the sourcify-server, an HTTP-based verifier and storage solution, and the sourcify-monitor, an automated listener for EVM chains facilitating seamless contract verification submissions. The project includes core libraries like @ethereum-sourcify/lib-sourcify for contract logic verification and @ethereum-sourcify/bytecode-utils for metadata extraction from bytecode, complemented by a user-friendly Sourcify UI. As an open-source initiative, Sourcify provides comprehensive resources for individuals to host their own verification environments and supports diverse platforms and browsers, fostering an open, verified contract repository. Complete documentation and community support are available through various channels, with guidance for integrating new chain support detailed in the project’s documentation.
