Beosin VaaS

Beosin VaaS (Verification as a Service) is a comprehensive Smart Contract Formal Verification Platform that provides automated mathematical proof-based verification for blockchain developers and projects. The platform combines static scanning, fuzzy testing, and formal verification capabilities to mathematically prove contract behavior matches intended specifications before deployment to production.

Multi-Blockchain Support

Beosin VaaS supports formal verification across multiple major blockchain platforms including Ethereum (ETH), BNB Chain (BSC), Polygon (MATIC), Aave, Ontology (ONT), EOS, and many others. This broad compatibility ensures developers can use the same security toolset regardless of their target blockchain.

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.

97%+ Accuracy Rate

Beosin VaaS achieves an accuracy rate above 97% in vulnerability detection, with precise code-level location of risky code segments. This high accuracy minimizes false positives while ensuring genuine security issues are not overlooked, making the platform suitable for production security workflows.

Formal Verification Technology

Unlike purely pattern-based security scanners, VaaS employs formal verification methods that mathematically prove contract behavior matches intended specifications. The platform performs in-depth bytecode inspection and generates formal rules based on business requirements, providing the highest assurance of smart contract correctness. This approach can identify subtle logical flaws that traditional testing methods might miss.

Multi-Method Analysis Approach

The platform combines multiple analysis techniques:

• Static Analysis: Examines code without execution to identify structural vulnerabilities
• Fuzzy Testing: Automatically generates test cases with randomized inputs to trigger edge cases
• Formal Verification: Mathematically proves correctness properties and invariant verification
• Property-Based Testing: Validates that contracts maintain specified properties under all conditions

This multi-method approach provides defense-in-depth security analysis.

Precise Risk Code Location

When vulnerabilities are detected, VaaS pinpoints the exact lines of code responsible, along with detailed recommendations for remediation. This precise localization dramatically reduces the time developers need to spend investigating and fixing security issues.

Developer-Friendly Integration

Beosin VaaS is designed for integration into development workflows, enabling security to be addressed early in the development lifecycle rather than as a final pre-deployment step. The platform's detailed recommendations help developers improve their security practices over time.

Why Choose Beosin VaaS

With support for 100+ vulnerability types across multiple blockchains, 97%+ accuracy, precise code-level issue identification, and formal verification capabilities, Beosin VaaS provides smart contract developers with enterprise-grade automated mathematical proof-based security analysis. The platform's combination of static scanning, fuzzy testing, and formal methods offers comprehensive coverage that goes beyond traditional security tools.
