The Ethereum Foundation’s Trillion Dollar Security initiative has awarded a grant to the Freedom of the Press Foundation to support WEBCAT, an open-source project that helps browsers verify website code against a signed manifest. The funding will cover a verification library for Ethereum wallets, Chromium-browser research, implementation support, an independent audit and proposed standardization work. WEBCAT addresses a gap between encrypted website connections and confirming that a site is delivering code approved by its developers. A compromised front end could change a recipient address or display a signature request that differs from the one ultimately presented to a user. The project’s current alpha Firefox extension blocks a page and warns users when verification fails. Protection is not automatic across Ethereum wallets: wallet extensions must integrate the library, and application teams must enroll their domains and serve a signed manifest with each release. The work is intended to complement Clear Signing, which helps users understand what they are approving, while WEBCAT focuses on verifying an enrolled application’s front-end integrity. Neither mechanism replaces transaction-detail checks or secure application infrastructure maintained by development teams.
