Protect your smart contracts with AI + manual audits. Prevent exploits, boost investor trust & meet exchange listing requirements.

Smart Contract Audits That Prevent Exploits Before They Happen

Billions in assets are locked in smart contracts, and one line of code can expose them to attackers.

CredShields blends AI-powered scans and expert manual reviews to deliver comprehensive audits trusted by leading Web3 protocols and exchanges.

You can count on us to monitor every stage of smart-contract development, from manual code review to automated testing. We leave no stones unturned to find security vulnerabilities during the audit. Upon completing the audit, our team provides a detailed report outlining the tests performed and the security issues identified, including best practices for improved security.

Why It Matters

  • $3B+ lost in blockchain exploits in 2023
  • One compromised wallet or bridge can affect the entire ecosystem
  • Exchanges and protocols must meet compliance standards for listings

Our Process

  • Initial Assessment & Threat Modeling
  • AI-Powered Automated Scanning (via SolidityScan)
  • Manual Line-by-Line Code Review
  • Remediation Support + Retesting
  • Final Audit Report + Certification
