BP 2024: Technical Talk: Open Source X-Ray: Solana Smart Contract Static Analysis
By breakpoint-24
Published on 2024-09-20
Chris Wang announces the open-source release of X-ray, a static analyzer for Solana smart contracts
In a groundbreaking announcement at Breakpoint 2024, Chris Wang revealed that X-ray, a powerful static analyzer for Solana smart contracts, is now open-source. This move is set to revolutionize how developers approach security in the Solana ecosystem.
Summary
Chris Wang, a security researcher and software developer, introduced X-ray, a static analyzer specifically designed for Solana smart contracts. The tool, which has been in development and use for over two years, is now being released as an open-source project. This release aims to empower developers to build and contribute their own security rules, enhancing the overall security of the Solana ecosystem.
X-ray is built on the LLVM technology stack and can convert source code into an intermediate representation for analysis. It's designed to be cross-platform, working on Mac, Windows, and Linux. The tool can identify potential security vulnerabilities in smart contracts, including common issues like buffer overflows and arithmetic overflows.
The open-source version of X-ray includes many of the most common security rules that have been developed and refined through years of use in the cybersecurity community. By making X-ray open-source, the Solana Foundation is fostering a collaborative approach to security, allowing developers to not only use the tool but also to modify and expand its capabilities.
Key Points:
Open-Source Release
X-ray, a static analyzer for Solana smart contracts, is now available as an open-source tool. This release marks a significant step in democratizing security tools within the Solana ecosystem. By making the source code freely available, the Solana community can now contribute to its development, customize it for specific needs, and collectively improve the security landscape of Solana smart contracts.
The open-source version includes a comprehensive set of security rules that have been developed and refined over more than two years of active use in the cybersecurity community. This means that developers will have access to battle-tested security checks right out of the box, providing a solid foundation for securing their smart contracts.
Cross-Platform Compatibility
X-ray has been designed with versatility in mind, offering cross-platform compatibility across Mac, Windows, and Linux operating systems. This wide-ranging support ensures that developers can utilize X-ray regardless of their preferred development environment.
The tool's flexibility extends beyond just operating systems. X-ray can be deployed through various methods, including a Docker image for easy integration into continuous integration pipelines, pre-built binaries for quick setup on supported platforms, and source files for those who wish to compile the tool themselves or make modifications.
LLVM Technology Stack
At its core, X-ray leverages the LLVM (Low Level Virtual Machine) technology stack. This choice of foundation brings several advantages to the tool. LLVM is known for its modular design and optimization capabilities, which allows X-ray to perform efficient and thorough analyses of smart contract code.
By converting source code into LLVM's intermediate representation, X-ray can apply sophisticated analysis techniques that go beyond simple pattern matching. This approach enables the tool to detect subtle security vulnerabilities that might be missed by less advanced analysis methods.
Customizable Rules
One of the most powerful features of X-ray is its ability to be extended with custom rules. The tool is designed not just as a static set of checks, but as a framework that empowers developers to create and implement their own security rules.
This customizability is crucial in the rapidly evolving landscape of blockchain security. As new types of vulnerabilities are discovered or as projects implement unique security requirements, developers can quickly adapt X-ray to check for these specific issues. This flexibility ensures that X-ray can remain an up-to-date and relevant tool for Solana smart contract security.

Questions Answered
What is X-ray?
X-ray is a static analyzer specifically designed for Solana smart contracts. It's a tool that examines the source code of smart contracts without executing them, looking for potential security vulnerabilities and other issues. X-ray uses sophisticated analysis techniques based on the LLVM technology stack to provide developers with insights into the security of their code.
Why is X-ray being open-sourced?
X-ray is being open-sourced to empower the Solana developer community to contribute to and improve the tool. By making the source code freely available, developers can not only use X-ray but also modify it, add new security rules, and adapt it to their specific needs. This collaborative approach aims to enhance the overall security of the Solana ecosystem by leveraging the collective expertise of its community.
How can developers use X-ray?
Developers can use X-ray in several ways. The simplest method is to use a pre-built Docker image, which allows for easy integration into existing development workflows. For those who prefer local installation, pre-built binaries are available for supported platforms. Additionally, developers who want to modify the tool or contribute to its development can compile X-ray from the source code, which is now openly available.
What types of security vulnerabilities can X-ray detect?
X-ray is capable of detecting a wide range of security vulnerabilities common in smart contracts. These include buffer overflows, arithmetic overflows, and other issues that could potentially be exploited by malicious actors. The tool comes with a set of pre-defined rules for common vulnerabilities, and developers can also create custom rules to check for project-specific security concerns.
Can developers create their own rules for X-ray?
Yes, one of the key features of X-ray is its extensibility. Developers can create and implement their own custom security rules. This capability allows the tool to be adapted to specific project requirements or to check for newly discovered types of vulnerabilities. The ability to add custom rules ensures that X-ray can evolve alongside the rapidly changing landscape of blockchain security.
What platforms does X-ray support?
X-ray is designed to be cross-platform, supporting Mac, Windows, and Linux operating systems. This broad support ensures that developers can use the tool regardless of their preferred development environment. The flexibility in deployment options, including Docker images and pre-built binaries, further enhances its accessibility across different platforms.
How long has X-ray been in development?
According to the announcement, X-ray has been in active development and use for over two years.
