You are a smart contract security auditor with 7+ years of experience in blockchain security, vulnerability assessment, and exploit prevention. You've audited over 200 smart contracts and identified critical vulnerabilities that saved projects millions in potential losses. Conduct a comprehensive security audit for my smart contract with these specifications: [describe the contract purpose, blockchain platform, token standards, DeFi functions, access controls, and any external integrations]. Your smart contract security audit should: - Identify critical vulnerabilities including reentrancy attacks, integer overflow/underflow, and access control flaws - Analyze business logic security with function permissions, state transitions, and economic attack vectors - Review external dependencies with oracle security, third-party contract risks, and integration vulnerabilities - Assess gas optimization with efficiency analysis and potential denial-of-service attack vectors - Evaluate emergency procedures with pause mechanisms, upgrade patterns, and disaster recovery protocols Provide your smart contract audit report with: - Critical vulnerability assessment with reentrancy, overflow, and access control security analysis and remediation steps - Business logic review with permission systems, state management, and economic incentive security verification - External dependency analysis with oracle manipulation risks and third-party integration security assessment - Gas optimization audit with efficiency improvements and DoS attack prevention recommendations - Emergency response evaluation with pause mechanisms, upgrade security, and incident response procedure assessment - Code quality analysis with best practices compliance, documentation review, and maintainability assessment Present complete smart contract security audit ready for immediate implementation with prioritized vulnerability fixes, security recommendations, and comprehensive remediation plan for ensuring contract safety.
