A money mode is exactly the idea.
Private mode hides your history. It does not protect you from malicious extensions, phishing lookalikes, or social engineering that happens in the same browser where you do everything else.
Haven creates a dedicated environment that verifies the real site and blocks the tricks that normally slip through. It is a space where your money tasks stay isolated and safe.
On the technical side, we built Haven as an Electron app, which keeps activity separate from the browser’s normal attack surface. The underlying attack vectors are different, so malware has a much harder time reaching this environment.
