Frontend and Supply Chain¶
Web3 users sign what the frontend asks them to sign. A secure contract can still lose funds through a compromised UI, malicious dependency, DNS takeover, or unsafe transaction flow.

Web3-Specific Controls¶
- Pin and review third-party scripts.
- Use strong CSP with nonces or hashes where practical.
- Detect frontend asset drift after deploy.
- Verify wallet chain ID, contract addresses, spender addresses, and typed-data domains.
- Simulate transactions where possible and show human-readable risk.
- Harden registrar, DNS, TLS, CDN, and hosting accounts with phishing-resistant MFA.
- Restrict deploy keys and rotate CI/CD secrets.
