Mitilena Wallet — cold wallet
Main application. Free. Non-custodial cryptocurrency wallet — desktop and mobile.
Mitilena Air
Companion app that turns your Mitilena NFC card into a full hardware wallet — completely offline. No internet permission, zero network traffic — keys never touch servers or cloud. Phones first, also Windows, macOS and Linux.
Sign crypto with zero internet, no cables, no USB drives. Your online phone plays a sound — the offline phone hears it, signs the transaction and plays a sound back. Turn any old smartphone in Airplane mode into a 100% offline hardware wallet.
▶ WATCH IT IN ACTION →Write your seed phrase to the NFC card. The app is guaranteed to be offline: no internet permission in the manifest, confirmed by Google Play moderation.
Secure it with a password and biometrics. You can safely use your daily phone since the app technically cannot reach the network at all.
Sign transactions fully offline. For ultimate security, install the app on an old smartphone you no longer use to create a 100% true air-gapped hardware wallet.
No internet permission in the app manifest — verified by Google, zero network traffic: a leak is physically impossible. The recovery phrase is born on a pure verified randomizer, the exact same engine the main wallet uses when you create a new address. No accounts, no cloud, no tracking. Back your keys up on NFC cards or small NFC stickers — put them on your furniture or give them to your family. Requires a Mitilena license — activate via NFC card, QR code or manual entry.
