Smart contract audit reports contain information critical to your protocol's security — but they can be dense, technical, and difficult to parse if you haven't read many of them. This guide breaks down every section you'll encounter in a professional audit report, and explains how to turn findings into action.

The executive summary

Every audit report opens with an executive summary that gives a high-level picture of the contract's security posture. Key elements include:

  • Overall risk rating: A qualitative assessment (Critical/High/Medium/Low/Informational) of the most severe outstanding finding.
  • Finding counts by severity: How many Critical, High, Medium, Low, and Informational issues were found.
  • Audit scope: Which contracts and which commit hash were reviewed — critical for confirming what was and wasn't audited.
  • Deployment recommendation: Whether the auditors recommend deploying as-is, after specific fixes, or only after full re-audit.

Understanding severity levels

Severity ratings are the most important output of an audit report, but their definitions vary between firms. The most common framework:

  • Critical: Direct loss of user funds or complete protocol compromise is possible without restrictions. Fix before any deployment.
  • High: Significant risk to user funds or protocol functionality. Fix before mainnet launch.
  • Medium: Meaningful risk that may require specific conditions to exploit, or that causes significant protocol malfunction. Fix before launch where possible.
  • Low: Minor risk, often requiring unlikely preconditions. Fix in a subsequent deployment.
  • Informational: Code quality, best practice suggestions, and gas optimizations. No direct security risk, but worth addressing.

Individual findings

Each finding in the report typically includes:

  • Title and severity: A descriptive name for the issue and its severity classification.
  • Description: What the vulnerability is and how it exists in the code.
  • Impact: What an attacker could achieve by exploiting it.
  • Proof of Concept: Sometimes included — a demonstration of how the attack would work, often as pseudocode or a test.
  • Recommendation: The auditor's suggested fix.
  • Client response: In interactive audits, the development team's response (Acknowledged / Fixed / Won't Fix).

How to prioritize remediation

Don't treat all findings equally. Use this prioritization framework:

  1. Fix all Critical and High findings before any deployment. No exceptions.
  2. For Medium findings, assess the likelihood of exploitation and the impact on user funds. Fix any that could cause significant loss under plausible conditions.
  3. For Low and Informational findings, batch them into a follow-up release — they don't need to block your launch.
  4. For every fix, re-run automated tools on the changed code and request a partial re-review from the audit firm.

What good reports look like vs. bad reports

Not all audit reports are equal. Warning signs of a poor-quality audit include:

  • Only informational and low findings when the codebase is complex — a sign the auditor didn't look hard enough.
  • Generic finding descriptions with no specific line references — copy-paste findings from other audits.
  • No scope definition or commit hash — you can't verify what was actually reviewed.
  • No remediation re-review — the firm didn't check that the fixes worked.

AI audit reports vs. manual audit reports

AI-powered platforms like SmartContract.us generate structured audit reports that follow the same format as professional reports — with severity ratings, descriptions, impact, and recommendations — but produced in under a minute. AI reports are ideal for development-time security checks and pre-audit preparation. Professional manual reports go deeper on economic attacks and protocol-level logic that require human reasoning and context.
