Sanctum adds 2-of-3 multisig security to every app wallet

The Solana staking protocol now splits wallet control across a phone, a cloud backup, and an email-linked recovery key Sanctum has rolled out a 2-of-3 multisig setup for every wallet inside its consumer mobile app. Transactions now need sign-off from any two of three separate keys before they go through. For a protocol best known for liquid staking and yield on Solana , it is a notable change of emphasis. The pitch is no longer only about growing your assets. It is also about making sure they are still there tomorrow. Sanctum’s version splits control across three locations. The first is a device key , stored on the user’s phone and gated by biometrics. The second is a cloud key , kept in either iCloud or Google Drive.
