Security isn't a checklist. It's a loop. Every engagement follows the same disciplined cycle repeated with every fix and upgrade. That's why teams keep coming back.
We build an independent model of your system directly from the code, mapping every state transition, trust boundary and economic assumption.
Model
Senior researchers attack it adversarially, by hand, line by line, validating findings against deep knowledge from hundreds of real-world exploits.
Break
Every finding ships with clear severity, reproducible proof-of-concept and concrete remediation guidance, then we re-audit the fixes.
Report
Proprietary AI tooling widens coverage across the full surface, surfacing edge cases for a human to confirm, never replacing the senior auditor.

The MixBytes team was highly engaged throughout the audit, consistently available and proactive with insightful questions that demonstrated a deep understanding of the protocol. Their commitment to a thorough review, high level of expertise, adherence to deadlines, and professional approach made the audit process smooth and effective.

We’ve been working with MixBytes since 2020, and they’ve audited all of our core systems: DEX, lending and stablecoin infrastructure, as well as the DAO and Hybrid Vaults within Yield Basis. They’ve developed a strong understanding of our architecture, making each audit more efficient. A reliable, consistent security partner whose context and collaboration we highly value.
Michael Egorov
It has been great. We are quite satisfied with the audits. Overall, I will suggest MixBytes to any other team I come across!
