Smart Contract Security Audits

HashEx provides comprehensive smart contract security audits with over 8 years of experience in blockchain security. The audit process includes meticulous code review, automated and manual testing, vulnerability assessment, penetration testing, and detailed reporting with actionable recommendations. The company has completed over 1,500 smart contract audits and prevented the loss of over $4 billion in investor funds.

What's Included

The audit covers all aspects of smart contracts including:

• Underlying logic and algorithms review
• Data structures and architecture analysis
• External dependencies assessment
• Code written primarily in Solidity and Rust
• Advanced tools including Solidity Compiler, static and dynamic analysis
• Frameworks like Truffle Suite and Ganache
• Comprehensive code analysis and formal verification
• Risk assessment and vulnerability identification

Audit Methodology

HashEx employs a multi-layered approach combining:

Code Review and Analysis

• Meticulous line-by-line code review
• Automated static and dynamic analysis
• Manual testing by experienced auditors
• Identification of logic vulnerabilities

Penetration Testing

• Simulated attack scenarios
• Attempting to exploit identified vulnerabilities
• Testing authentication and authorization mechanisms
• Evaluating overall security posture
• Creative attack scenarios beyond automated scanners

Risk Analysis

• Examination of smart contract logic
• Identification of potential attack vectors
• Assessment of economic risks
• Evaluation of governance vulnerabilities
• Analysis of external dependencies

Process and Deliverables

The audit process follows a structured approach:

1. Initial Phase: Receive code specifications, provide quote and timeline
2. Audit Phase: Conduct thorough automated and manual reviews
3. Preliminary Report: Deliver detailed findings and recommendations with severity ratings
4. Remediation: Clients address identified issues
5. Review and Recheck: HashEx reviews fixes (complimentary recheck service included)
6. Final Report: Publish comprehensive final audit report

Results are presented in detailed reports categorizing findings by severity, providing proof-of-concept exploits for identified vulnerabilities, and offering specific remediation recommendations.
