CD Security has completed more than 200 audits and helped secure over $15 billion on-chain, working with Polygon, Euler, Supra Labs, Flow Blockchain, Hyperlend, Azuro and many other protocols.
We audit smart contracts and blockchain protocols to uncover vulnerabilities that could put user funds and critical operations at risk. Our reviews examine your code, architecture, economic logic and the interactions between connected components.
Senior researchers on every audit
Every audit is performed exclusively by senior security researchers, each with 100+ completed audits. Our team includes bug bounty winners, and we select auditors whose expertise matches your protocol’s technology and complexity.
Deep manual review, reinforced by AI
We combine manual code review, targeted fuzzing and protocol-aware testing to investigate how your system could be exploited. Our in-house AI scanning tool adds another layer of analysis, with potential findings triaged and validated by our auditors.
Direct communication through to verified fixes
Your developers work directly with the researchers reviewing your code. We explain each finding, its potential impact and how to address it, then verify your fixes and document their status in the final report.
