Smart contract audits, DeFi security, and blockchain infrastructure assurance for Layer 1s, protocols, and Web3 projects.
SigIntZero delivers comprehensive smart contract security audits through a structured six-phase process covering static analysis, manual code review, fuzzing, architecture review, and compliance advisory. Its proprietary AI engine, Sentinel, extends coverage at scale alongside deep expert-led examination.
SigIntZero is a smart contract security audit firm serving Layer 1s, DeFi protocols, and Web3 projects worldwide. Audits span the full security surface: static analysis, manual code review, business logic verification, fuzzing and advanced testing, architecture and trust assumption mapping, zero-day vulnerability research, best practices review, technical due diligence, social and operational risk assessment, and compliance advisory. The firm follows a structured six-phase process (Recon, Automated Sweep, Agentic Analysis, Cross-Examination, Human Validation, Report) that pairs senior security researchers with Sentinel, a proprietary AI engine for automated scanning and analysis at scale. SigIntZero focuses on depth and cross-examination over checkbox compliance, targeting the gap exposed by the $10.77B+ lost to exploits among protocols that passed traditional audits.
Smart contract vulnerabilities and operational risks in Web3 projects often go undetected by traditional manual audits, leading to costly exploits. Continuous threat detection is also lacking, leaving deployed contracts exposed to fast-moving attacks.
