PROVEN PROCESS
Our Cairo-Specific Audit Methodology
Our structured, multi-layered approach is designed to uncover critical vulnerabilities in StarkNet Cairo smart contracts, ensuring your protocol's security and reliability before mainnet deployment.
01
Architecture & Design Review
We analyze your system's architecture for logical flaws, centralization risks, and Cairo-specific design patterns. This pre-code review ensures a solid foundation for secure development.
