Overview
What is Umbra Privacy?
Umbra Privacy is a privacy protocol built on Solana described as “incognito mode for your money”. It runs on Arcium, a multi-party computation (MPC) layer that handles encrypted execution, enabling users to shield token balances, send confidential trasnfers, and interact with DeFi privately. The protocol went live on public mainnet in early 2026, with a mobile app available via TestFlight for iOS users. Umbra raised approximately $3M through an oversubscribed ICO on MetaDAO in October 2025.
