Privacy-First Mobile Browser with Encrypted Search

Executive Summary

Phantom Browser is a lightweight, privacy-first mobile browser that uses Arcium's multiparty computation (MPC) to enable truly anonymous web searching. Built by Aether Labs for the Solana Mobile Hackathon and Arcium Fellowship, it delivers essential browser features without surveillance.

The Problem

• Chrome tracks everything - 65% of users have zero browsing privacy
• "Privacy" browsers still leak search queries to Google/Bing
• Mobile users need lightweight, fast browsing without feature bloat
• Current solutions are privacy theater - not actual privacy

The Solution

Phantom Browser keeps all browsing data encrypted locally while using MPC to anonymize search queries. Users get a clean, fast browser experience with genuine privacy protection.
