# Front-End Integrity Becomes a Security Frontier

As contract auditing matures, theft keeps migrating to the delivery layer of web interfaces, and verifying served code becomes a standard requirement for wallets and applications rather than an optional extra.

## Recent evidence

- [confirms] Ethereum Foundation Funds a Tool That Lets Browsers Verify a Website Has Not Been Tampered With (2026-08-06): The WEBCAT grant targets attacks that have repeatedly drained users who interacted with an unmodified smart contract through a legitimate site. Framing the threat as one that audited contracts cannot address is the argument that turns served-code verification into a standard wallet and application requirement.
- [confirms] Ethereum Foundation Funds Browser Tool That Checks Whether a Website Serves the Code It Published (2026-08-06): The Ethereum Foundation's Trillion Dollar Security programme funded the Freedom of the Press Foundation to build WEBCAT, a browser tool that checks whether a website serves the code it published. Foundation money going to delivery-layer verification signals that front-end tampering is now treated as core protocol security rather than an application-vendor problem.
