Auditorias de Contratos Inteligentes
Auditorias de contratos inteligentes avaliam segurança e eficiência revisando design e lógica, combinando análise automatizada com revisão manual.
Visão geral: O objetivo de uma auditoria de contrato inteligente é minimizar o risco validando propriedades de segurança e correção funcional. Metodologia: Auditorias combinam ferramentas automatizadas (Slither, MythX) com revisão manual. Vulnerabilidades: Problemas típicos incluem reentrância, controle de acesso impróprio e erros aritméticos.

❓ Perguntas frequentes
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.
