Smart contract auditing is a crucial step in ensuring the security and reliability of blockchain applications. Accelchain employs Symbolic Execution as a powerful technique for auditing contracts, identifying vulnerabilities, and adhering to the guidelines specified by the Ethereum.org SWC (Smart Contract Weaknesses and Common Vulnerabilities) Registry.
Definition: Symbolic Execution involves systematically exploring possible program states by running contract bytecode and its dependencies through a compiler.
Process: The contract is executed symbolically, and the analysis encompasses multiple transactions and potential states.
Comprehensive Analysis: Accelchain integrates with a compiler to analyze contract bytecode thoroughly.
Dependency Consideration: The process includes all dependencies, such as imported contracts, ensuring a holistic approach to auditing.
SWC IDs and Test Cases: Test cases are designed with a focus on SWC IDs specified by the Ethereum.org registry.
Exploration of States: Test cases systematically explore various program states, identifying potential vulnerabilities.
Detailed Information: The resulting audit report provides detailed information on identified vulnerabilities.
Report Components: SWC Error ID, Error Title, Function with the error, lines containing the error, and severity are included.
Severity Levels: Issues are categorized by severity, allowing prioritization based on the criticality of each vulnerability.
