Smart Contract Security Audits

Cyfrin delivers comprehensive smart contract security audits through both private dedicated audits and competitive crowdsourced reviews via CodeHawks platform. Services provide end-to-end blockchain security solutions to help organizations and institutions protect users and assets from DeFi exploits.

Private Audits

Dedicated Security Team: Fully dedicated team of lead security researchers assigned to your project, providing the highest level of expertise and attention from researchers with backgrounds at Chainlink, Alchemy, Aragon, WorldCoin, Microsoft, and Google.

Comprehensive Audit Process: Six-step process including setup and onboarding, commit hash locking, deep code review, initial reporting, mitigation support, and final verification. Average 2-week turnaround time.

Expert Analysis: Security researchers conduct manual code review, automated static analysis, and dynamic testing to find, report, and mitigate critical vulnerabilities. Average of 25 vulnerabilities found per audit across over $40 billion in protected TVL.

Detailed Reporting: Initial and final audit reports explaining each issue categorized as High, Medium, Low, or Informational, with specific vulnerability assessment reports and remediation guidance.

Direct Communication: Open communication channel between Cyfrin engineers and client teams throughout the audit process, including setup calls and findings review sessions.

Mitigation Support: Engineering team receives dedicated support to apply fixes, with final verification from Cyfrin researchers marking issues as Acknowledged or Resolved.

Confidential Reports: Private audits include confidential reporting, allowing teams to address vulnerabilities before public disclosure.

24/7 Support: Dedicated account manager and around-the-clock support to assist with any questions or issues.

CodeHawks Competitive Audits
