What Is a High Security Score in Smart Contract Audits

In the world of DeFi, a high security score signals strong audit findings, but it is not a guarantor of safety. This score is a percentile, ranking a contract against a dataset of audited code. Understanding its meaning helps in doing thorough due diligence beyond the number.

What the Score Represents

The score is a percentile value derived from a comparative audit dataset. A percentile around the 95th tier means the contract performed better than about 95% of audited code in the sample. It captures factors like code quality, testing depth, and audit breadth, but does not guarantee immunity from future bugs. For context, you can read more on how audits benchmark code and why governance matters. See Ethereum's smart contracts docs for broader context.

When you see a high percentile, consider KYC checks and project credibility as complementary factors. See how other criteria such as decentralization scores influence risk.

How Percentiles Are Calculated

Auditors aggregate a wide range of signals—control flow, reentrancy patterns, testing suites, and historical incident data—to position a contract in a percentile distribution. A value like 95.58 indicates strong relative performance within the tested universe. However, reviewing security considerations and the audit scope remains essential.

Readers should also connect this metric to broader research, such as veToken models and how governance design affects security incentives.

Limitations and Due Diligence

A high score reduces risk but does not eliminate it. Audit artifacts capture observed behavior but cannot foresee novel exploits. Always pair the score with ongoing monitoring, community signals, and practical testing. For risk assessment, consider patterns that show proactive security work, not just numbers.

As part of due diligence, review practices such as ongoing vulnerability programs and red flags flagged in security metrics and post-audit follow-ups. The broader context is critical; a score is one dimension of a robust security posture.

Practical Tips for Investors

  • Use the score as a compass, not a destination. Follow up with code review and live testing.
  • Cross-check with official security guidance and audit reports to gauge coverage.
  • Incorporate internal signals, such as decentralization indicators and governance structure.
  • Educate yourself on the broader risk landscape, including anonymous-team risks and audit quality variations.
