Conduct an External Web2 Security Review

While most security reviews in Web3 focus on smart contracts, decentralized applications (dApps) also rely heavily on traditional Web2 components such as JavaScript/TypeScript frontends, Python or Node.js backends, and API services. A Web2 code audit reviews these off-chain components for security flaws.

What a Web2 Code Audit Covers

• Frontend applications

  • Secure use of wallet integrations (Metamask, WalletConnect, etc.)
  • Handling of transaction construction logic
  • Prevention of client-side vulnerabilities (e.g., XSS, unsafe eval, DOM injection)
• APIs and backend services

  • Authentication and session management
  • Data validation and sanitization
  • Secure API design and rate-limiting
• Dependency and package security

  • Insecure npm/pip packages
  • Typosquatted or malicious libraries
  • Unmaintained dependencies with known CVEs
• Secret and key management

  • API keys and private keys exposed in code or .env files
  • Misconfigured access controls in cloud services
