The Ethereum Foundation launches the Universal Ethereum Signer app on Passport Prime

Odaily reports that the Ethereum Foundation is launching the Universal Ethereum Signer app on Foundation's Passport Prime hardware device. The app runs on the KeyOS operating system and is currently in beta. It was developed by Ledger co-founder and current ZKnox CEO Nicolas Bacca with funding from the Ethereum Foundation, allowing users to review and sign Ethereum transactions on a standalone, isolated hardware device without handing private keys to a phone or computer. For Passport Prime users, this marks the first time the device can serve as a dedicated signer for Ethereum transactions through a third-party app.
