Smart Contract Security Audits & Threat Modeling

Comprehensive security services combining smart contract audits, threat modeling, and expert consultation to identify vulnerabilities and ensure blockchain protocols operate securely before deployment. The engagement includes systematic vulnerability assessment, proactive threat analysis, and customized security guidance from experienced auditors.

Smart Contract Audit Process

Every audit follows a rigorous 7-step methodology:

1. Initial Contact: 24-hour response to discuss project scope and specific security needs
2. Customized Proposal: Tailored offer addressing unique security requirements
3. Contract & Initial Payment: 50% upfront fee after contract signing
4. Audit Execution: Thorough examination identifying vulnerabilities, design issues, and compliance gaps through threat modeling, automated testing, and manual code review by expert auditors
5. Audit Report & Final Payment: Detailed findings categorized by severity (Critical to Informational) with recommended solutions and clear impact explanations
6. Corrections & Retest: Verification that remediated issues are properly resolved
7. Final Sign-off: Confidence to deploy with rigorously tested, secure code

Audit Methodology

Every security review includes:

Threat Modeling: Understanding the specific threat landscape, identifying critical assets, mapping attack vectors, analyzing real attack scenarios, and assessing likelihood and impact to prioritize risks

Automated Testing: Using specialized security tools to identify common vulnerabilities and code patterns that could lead to exploits

Manual Review: Expert examination by experienced security auditors who understand protocol-specific risks and complex vulnerability chains

SCSVS Compliance: Following the Smart Contract Security Verification Standard co-created by Composable Security to ensure comprehensive coverage

Threat Modeling Services

Proactive security analysis helps development teams build secure foundations through:

• Critical Asset Identification: Determining what needs protection in the protocol
• Attack Vector Mapping: Identifying possible entry points for adversaries
• Real Scenario Analysis: Evaluating realistic threat possibilities and weak points in protocol design
• Severity Assessment: Prioritizing threats by impact and likelihood
• Early Detection: Finding vulnerabilities before deployment when fixes are less costly
• System Understanding: Enriched comprehension of protocol interactions enabling more secure architecture

Security Consultation

Expert advisory services provide customized solutions for unique security challenges:

• Verification of security assumptions and design decisions
• Second opinions on protocol architecture
• Addressing non-standard security scenarios not covered by traditional audits
• Strategic security planning and trade-off analysis
• Professional support leveraging years of specialized experience

Deliverables

Audit Reports: Comprehensive findings with severity categorization, recommended solutions from security experts, and clear explanations of potential impact. When vulnerabilities are fixed before launch, they are marked as resolved to demonstrate commitment to security.

Threat Models: System diagrams, detailed threat analysis, severity levels, actionable remediation steps, and technical/executive summaries for both development teams and leadership.

Consultation Reports: Custom-structured answers to client questions, analysis results, and expert recommendations addressing specific security concerns.

Pricing and Timeline

Smart Contract Audits: Typically $10,000-$30,000 based on lines of Solidity code (nSLOC), complexity, documentation quality, protocol familiarity, and timeline. Average duration: two weeks.

Threat Modeling: $5,000-$10,000 depending on project size, architecture complexity, and documentation clarity. Average duration: one to two weeks.

Security Consultations: $250/hour with engagements ranging from one to four days based on research depth and complexity.

Post-Engagement Support

After introducing changes, the team performs one-time verification to ensure recommendations are properly implemented and vulnerabilities are eliminated. Composable Security remains available for ongoing questions and security assistance.
