PROVEN PROCESS
Our Audit Methodology
Our structured, multi-layered audit approach delivers actionable security insights, not just a checklist. We focus on the unique attack vectors of IoT payment layers to secure your network's financial core.
01
Architecture & Specification Review
We analyze your system architecture, tokenomics, and protocol specifications to identify fundamental design flaws and logic errors before code review begins.

Frequently Asked Questions
Get clear answers about our specialized audit process for decentralized IoT payment networks, designed to address the unique security and operational challenges at the intersection of IoT and blockchain.
A comprehensive audit for a decentralized IoT payment layer typically takes 2-3 weeks from kickoff to final report. This includes a 5-day initial review and threat modeling phase, a 10-day intensive code and architecture analysis, and a final 3-day period for report compilation and client review. Complex protocols with custom oracles or novel consensus mechanisms may extend this to 4 weeks.
