Our Methodology
Our audit process is designed not only to find vulnerabilities but to challenge assumptions. We’re ensuring your system can stand up to the most critical scrutiny.
Every project is reviewed by two dedicated auditors, each working independently. This ensures fresh perspectives, avoids bias, and guarantees that findings are not influenced by groupthink.

A lead ChainSecurity engineer with hands-on experience in comparable projects oversees the process, acting as an internal challenger. Their role is to question, probe, and pressure-test the auditors’ findings.
Learn More →
Much like defending a thesis, auditors must justify their reasoning and methodology under scrutiny from their peers before the audit report is delivered.
Learn More →
Throughout the process, we keep an open communication channel adapted to your preferences. Weekly updates ensure progress visibility, while ad-hoc collaboration allows us to align closely with your team when needed.

After issues are resolved, we conduct a fixes review and re-audit to validate implemented changes. The final report provides a trusted third-party overview of your system, explaining its functionality and confirming it meets high security standards.

The same stable team, with their expertise and connections, continues supporting your project through ongoing consultations and future reviews. For most clients, the audit is just the start of a long-standing partnership.
