kandi X-RAY | halmos Summary

halmos is a Python library typically used in Ethereum applications. halmos has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has low support. You can install using 'pip install halmos' or download it from GitHub, PyPI.

Symbolic: Halmos executes the given contract bytecode with symbolic function arguments and symbolic storage states, enabling it to systematically explore all possible behaviors of the contract. Bounded: Halmos unrolls loops up to a specified bound and sets the size of variable-length arrays, allowing it to run automatically without the need for additional user annotations. Model Checking: Halmos proves that assertions are never violated by any inputs or provides a counter-example. This allows Halmos to be used for bug detection as well as formal verification of the contract. For more information, refer to our post on "Symbolic testing with Halmos: Leveraging existing tests for formal verification.".
