Smart Contract & Blockchain Audit Services

Fairyproof provides comprehensive security audit services for smart contracts, blockchain protocols, and cryptocurrency wallets across multiple networks including Ethereum, BNB Smart Chain, Polkadot, HECO, Waves, and COSMOS. The audit process combines automated security tools with thorough manual code review to identify vulnerabilities before deployment.

Audit Services Offered

Smart Contract Audits - Comprehensive security assessment for blockchain-based smart contracts using a rigorous three-phase approach: (1) Manual code review reading source code line-by-line to identify potential vulnerabilities, (2) Automated testing and symbolic execution to determine inputs causing different program executions, and (3) Formal verification using industry-leading methodology and tooling to mathematically ensure programs work as intended.

Blockchain Protocol Audits - Complete blockchain protocol security assessment examining blockchain client implementations, consensus protocols, network communication layers, cryptographic implementations, and overall system architecture. Identifies vulnerabilities at the protocol level that could affect the entire blockchain network's security and stability.

Wallet Security Audits - Comprehensive security assessment for cryptocurrency wallets including web wallets, mobile wallets, hardware wallet integrations, and browser extension wallets. Examines private key generation and storage mechanisms, transaction signing and validation processes, seed phrase implementation, user authentication controls, and integration with blockchain networks.

Security Testing - Goes beyond static code analysis to include dynamic testing, penetration testing, and real-world attack simulations using white-box testing with full source code access and black-box testing from an external attacker's perspective.

Audit Methodology

The comprehensive audit process includes code review with specification comparison to ensure code accomplishes intended functions, test coverage analysis to determine whether test cases adequately cover the codebase, symbolic execution and automated analysis, best practices review based on latest industry and academic research, and formal verification providing highly accurate mathematical proof of correctness.

Automated Security Tools

Fairyproof offers a cloud-based static analysis tool that allows developers to upload Solidity source code anytime for immediate security assessment. The tool comprehensively scans code to identify common vulnerability patterns including reentrancy vulnerabilities, integer overflow/underflow, access control issues, gas optimization problems, unsafe external calls, and uninitialized storage pointers.

Deliverables

• Detailed audit reports with findings and remediation recommendations
• Vulnerability assessment with severity ratings
• Post-audit support and verification of fixes
• Integration with project development lifecycle
• Immediate automated scanning results for continuous development

Fairyproof has successfully audited numerous high-profile projects including MDEX Exchange, OpenOcean, Accumulate, Atlas Dex, BitKeep wallet, and many others, establishing a strong reputation in the blockchain security community.
