Smart Contract Security Audit

OXORIO's comprehensive smart contract security audit service provides manual auditing to detect sophisticated vulnerabilities, exploits, and loopholes within protocol logic. The service covers multiple blockchain languages including Solidity, Cairo, Rust, and Vyper, with specialized expertise in EVM-based solutions, Layer 2 technologies, and Zero-Knowledge proof systems.

Comprehensive Audit Process

The audit follows a stringent multi-phase process beginning with an initial consultation and scope definition, followed by detailed code analysis by teams of at least three specialists with minimum 5 years of experience. The methodology includes manual code review, automated scanning, attack vector analysis, business logic verification, and edge case testing. Clients receive interim reports every 1-2 weeks during the engagement, followed by a preliminary report highlighting all findings. After the client team addresses identified issues, OXORIO conducts a fix verification review and publishes a final comprehensive report.

Interactive Reporting System

Unlike standard PDF reports, OXORIO provides an interactive reporting platform that allows clients to easily track each finding's severity level, exact location in the code, remediation status, and technical details. This streamlined system accelerates the remediation process and enables better collaboration between security auditors and development teams.

Service Portfolio and Flexibility

OXORIO offers flexible engagement models including standard 1-6 week comprehensive audits, subscription-based ongoing security assessments for projects with continuous development, 3-day pre-audits for rapid vulnerability identification, and specialized services for deployment script auditing, contract upgrade reviews, and off-chain infrastructure security. The firm has successfully audited over 30 projects, identifying 450+ vulnerabilities and securing $25B+ in Total Value Locked across major DeFi protocols including Lido Finance, Aave, 1inch, Safe Global, and Polygon Village.

Specialized Zero-Knowledge Capabilities

OXORIO provides specialized security services for Zero-Knowledge proof systems, strengthening privacy and security through expert evaluation of zk-SNARK implementations, circuit designs, and cryptographic protocols. The service includes comprehensive security analysis of zero-knowledge circuits, verification of cryptographic assumptions, evaluation of trusted setup ceremonies, analysis of proof generation and verification logic, and assessment of circuit constraint systems. The team has expertise in multiple ZK frameworks including Circom, SnarkJS, ZoKrates, Noir, and Cairo.
