Secure Your Smart Services
Expert smart contract audits, DeFi protocol security assessments, and blockchain security reviews. We identify vulnerabilities in Solidity, Rust, and Move smart contracts across EVM chains, Solana, and other blockchain platforms.
Web3 Security Auditing?
Web3 Security Auditing is the systematic review of smart contracts, decentralized applications (dApps), and blockchain protocols to identify vulnerabilities that could lead to loss of funds, unauthorized access, or protocol manipulation. Unlike traditional software, smart contracts are immutable once deployed, making pre-deployment security critical.
Our team performs manual code review, automated analysis with tools like Slither and Mythril, formal verification where applicable, and economic modeling to identify reentrancy attacks, flash loan vulnerabilities, oracle manipulation, access control flaws, and protocol-specific logic bugs.
Our Process
A structured, comprehensive approach tailored to your specific needs and requirements.
Smart Contract Review
Code Architecture Analysis
Reviewing contract structure, inheritance patterns, upgrade mechanisms, and access control implementations.
Dependency Assessment
Analyzing imported libraries, OpenZeppelin usage, oracle integrations, and cross-protocol dependencies.
Specification Verification
Comparing smart contract behavior against project documentation and intended functionality.
Automated & Manual Analysis
Automated Scanning
Running Slither, Mythril, Echidna, and custom analyzers to detect common vulnerability patterns and invariant violations.
Manual Code Review
Expert line-by-line review for reentrancy, flash loan attacks, front-running, integer overflow, and logic vulnerabilities.
Formal Verification
Mathematical proof of critical invariants using formal methods where protocol complexity warrants it.
Economic & Logic Testing
Economic Attack Modeling
Analyzing tokenomics, incentive structures, and economic attack vectors including flash loan and MEV scenarios.
Protocol Simulation
Forking mainnet state for realistic attack simulations against live data and market conditions.
Integration Testing
Testing interactions with external protocols, oracles, bridges, and governance mechanisms.
Reporting & Remediation
Audit Report
Detailed findings report with severity classifications, proof-of-concept exploits, and gas optimization recommendations.
Fix Review
Verification of applied fixes to ensure vulnerabilities are properly addressed without introducing new issues.
Public Attestation
Optional public audit report for community transparency and trust building.
