Etherveil - An Ethereum Privacy Browser

Etherveil is a proposed Firefox-based browser, built on the Tor Browser's patch set with the Kohaku wallet engine embedded, that aims to make privacy a property of the runtime rather than a user setting. It enforces privacy across network, execution, and on-chain layers, so that all users within the same Fingerprint Profile class look identical to websites. The document is an early-stage architectural proposal, not a finalised implementation or security guarantee, and the name is tentative. Transactions route through Tornado Cash by default, UserOperations are submitted via Tor-routed ERC-4337 bundlers, and the design explicitly excludes extension compatibility and user-controlled fingerprint tuning. Several questions, including profile persistence, mixnet defaults, and web compatibility, remain open.
