A SYSTEMATIC APPROACH
Our Audit Methodology for Medical IoT Contracts
Our structured, multi-layered audit process is designed to identify and mitigate risks specific to the convergence of medical device firmware and blockchain logic, ensuring patient safety and regulatory compliance.
01
Architecture & Threat Modeling
We begin by analyzing the system architecture to map data flows between device sensors, on-chain logic, and off-chain components. This identifies critical attack surfaces and informs our targeted security review.

Medical Logic & Oracles Review
Deep analysis of the smart contract logic handling medical data (e.g., dosage tracking, patient vitals) and the oracle integration feeding real-world device data. We verify integrity, accuracy, and fail-safes.
