The Most Overlooked Part of a Smart Contract Audit: The Retest Phase

Most security issues aren’t in the first audit — they show up in the retest when fixes are verified. Yet many audit firms never perform a true retest.

Why Retesting Matters
• Fixes can introduce new vulnerabilities
• Code changes create new logic paths
• Exploitability often changes after patching
• A retest confirms the final state of the protocol
• Investors increasingly expect proof of retest

Checklist for a Real Retest
• Clear list of fixed items
• Verification steps
• New issues found during retest
• Updated severity ratings
• A final, revised report

Summary
Without a retest, teams and investors are left guessing whether vulnerabilities were actually resolved. This is why transparent auditors — including teams like ForceNow — treat the retest as a mandatory part of the process rather than an optional add-on.
