Аудит смарт-контрактів (Smart Contract Audits)
Аудит смарт-контрактів оцінює безпеку, коректність та ефективність шляхом огляду дизайну, логіки та реалізації, поєднуючи автоматизований аналіз з ручним оглядом.
Огляд: Мета аудиту смарт-контрактів — мінімізувати ризик шляхом перевірки властивостей безпеки, функціональної коректності та продуктивності. Методологія: Аудити поєднують автоматизовані інструменти (Slither, MythX) з ручним оглядом. Вразливості: Типові проблеми включають вразливості повторного входу (reentrancy), неправильний контроль доступу та помилки арифметики.

❓ Часті питання
What is included in a smart contract audit?
A typical audit covers code review, architecture assessment, vulnerability discovery (e.g., reentrancy, access control flaws), dependency analysis, testing and simulation, and a detailed remediation report with severity ratings and verification steps.
Do audits guarantee security?
No. Audits reduce risk by identifying and mitigating many vulnerabilities, but residual risk may remain due to undiscovered bugs, unknown interactions, or future changes in dependencies.
How long does an audit take?
Time varies with contract size, complexity, and scope. A small contract might take days, while larger systems with multiple interdependent contracts may require weeks, plus remediation and re-checks.
Is formal verification part of audits?
Formal verification is often reserved for critical components or high-assurance systems. It complements audits by mathematically proving specific properties, though it may not cover all contract behavior.
How are findings communicated?
Findings are delivered via a structured report that categorizes issues by severity, provides reproduction steps, impact assessment, remediation guidance, and a re-test plan.
What about dependencies and libraries?
Audits evaluate dependencies for known vulnerabilities, version stability, and integration risk. Dependency management practices, such as pinning and verified provenance, are emphasized.
