SECNORA Smart Contract Audit is a professional security auditing service targeting smart contracts deployed on blockchain platforms such as Ethereum. The service is aimed at identifying and remediating vulnerabilities before contract deployment, given the immutable nature of blockchain networks. The audit follows a multi-stage process: - Business logic review: Auditors analyze the contract's intended functionality, code structure, inter-contract interactions, and third-party dependencies. - Static and dynamic analysis: Code is reviewed without execution (static) and tested in a controlled environment (dynamic). - Formal verification: Mathematical proofs are applied to validate that the contract behaves as intended under all possible conditions. - Gas optimization: Contract code is reviewed to reduce execution costs and prevent failed transactions. - Access control review: Permissions and privileged roles (e.g., owners, administrators) are examined for misconfigurations. - Audit report and remediation guidance: A detailed report is produced with actionable steps for fixing identified vulnerabilities. Vulnerability classes addressed include reentrancy attacks, integer overflows/underflows, gas limit issues, and access control weaknesses. SECNORA is a CREST-accredited cybersecurity consulting firm. The audit process is customized to individual project requirements, and the team works with client development teams during remediation.
