Smart Contract Audit

Beosin's Smart Contract Audit service provides comprehensive security assessments for Web3 projects through formal verification technology and advanced cybersecurity techniques. The audit process combines automated analysis with expert manual review to identify and eliminate vulnerabilities in smart contract code.

Comprehensive Blockchain Coverage

The service covers most major blockchain platforms including Ethereum, BNB Chain, Polygon, Solana, Polkadot, Aptos, Sui, Arbitrum, Near, Cosmos, and zkSync. With over 4,000 smart contracts audited and 85,000+ vulnerabilities identified, Beosin has established itself as a trusted security partner for the Web3 ecosystem.

VAAS Formal Verification Technology

At the core of Beosin's audit methodology is their proprietary VAAS (Verification as a Service) formal verification engine, which performs in-depth bytecode inspection and generates formal rules based on business requirements. The platform supports 140+ test cases covering traditional vulnerabilities and business logic correctness, ensuring comprehensive security coverage with 97%+ accuracy rate.

Audit Process and Methodology

The audit workflow includes:

• Project Evaluation: Initial assessment of contract scope and complexity
• Requirement Discussion: Detailed analysis of business logic and security requirements
• Smart Contract Analysis: Line-by-line source code review, static scanning, and fuzzy testing
• Formal Modeling: Generation of formal verification rules based on requirements
• Expert Review: Security committee validation to ensure accuracy
• Sandbox Simulation: Project deployment and validation in controlled environment
• Report Delivery: Comprehensive audit report with vulnerability classifications and remediation recommendations

100+ Comprehensive Testing Items

The platform performs 100+ security testing items covering both traditional smart contract vulnerabilities (reentrancy, integer overflow, access control issues, etc.) and business logic correctness verification. This comprehensive approach ensures contracts are secure not just from known vulnerability patterns, but also from logic errors specific to the project's use case.

Professional Audit Reports

Beosin delivers itemized security vulnerability reports with visual charts, risk severity classifications, precise code-level location of risky code segments, and detailed fix recommendations. Each finding is validated through a multi-stage review process involving blockchain security experts to ensure accuracy and completeness.

Why Choose Beosin Audits

With thorough audit processes, professional reporting standards, and reasonable pricing, Beosin provides enterprise-grade security assessments that protect smart contracts from exploits while ensuring alignment with business requirements. The combination of automated formal verification and expert human analysis delivers superior accuracy compared to purely automated or manual approaches.
