Phink is an innovative, open-source fuzzing tool specifically designed for ink! smart contracts within the Polkadot ecosystem. Fuzzing is an essential in the developer toolbox and will increase the security and reliability of ink! smart contracts.
Developed by Security Research Labs (SRLabs), Phink aims to enhance the hacking resilience and robustness of smart contracts by utilizing advanced coverage-guided fuzzing techniques and smart mutations.
Enhanced Security Testing: Phink leverages cutting-edge fuzzers like AFL++ and Honggfuzz to provide comprehensive code coverage and systematic exploration of smart contract code paths, effectively identifying potential vulnerabilities.
Comprehensive Invariant Testing: By supporting both developer-specific and common smart contract invariants, Phink allows for rigorous verification of native code conditions and critical inputs, helping developers prevent bugs and ensuring long-term robustness.
Broad Compatibility: Designed to be free from ink! version dependencies, Phink enables developers to use their own runtime, storage, and state, making it highly flexible and applicable across various environments.
Open-Source and Easily Accessible: As an open-source tool, Phink encourages community contributions and continuous improvement. We create all resources necessary for developers to start fuzzing without the need for prior experience, including how-to tutorials and comprehensive documentation.
User-Friendly Interface: Phink includes an intuitive interface that visualizes code coverage, state transitions, and invariant testing results, making it accessible and easy to use for developers, auditors, and researchers.
SRLabs seeks funding to develop Phink, addressing the limitations of current smart contract fuzzing tools by incorporating advanced fuzzing techniques for more systematic and adaptive security testing. The project will involve the development of a fuzzing harness, custom instrumentation, a user-friendly interface, and thorough documentation to support community use and contribution.
