Ledger Unplugged

Contactless Bitcoin wallet

Ledger Unplugged is a Bitcoin wallet on a credit-card-sized Java Card, partnering with Fidesmo. You can use it with several mobile wallets to manage your account, protect your bitcoins and make safe payments.

A CONTACTLESS WAY TO SECURE YOUR BITCOINS

The Ledger Unplugged is the first contactless Ledger Wallet, a Java Card based wallet you can use on any NFC compatible device, like on Android last generations phones, or with an USB contactless reader. When you own bitcoins, storing and protecting them is your own responsibility. Secured thanks to highest banking industry standards, Ledger Unplugged is an excellent compromise between mobility and security, and your account can be backed up and restored if your Unplugged is lost or stolen.

AN OPEN SOURCE WALLET ADAPTED TO YOUR NEEDS

You can use your Unplugged to store safely your bitcoins offline, and to make everyday secure payments online. You can use it with Mycelium or GreenBits, popular and trusted wallets, or soon with Copay, for multi-users and multi-signatures transactions. As Ledger Unplugged is available as a Java Card applet on top of the Fidesmo platform, it is Open Source, you can download and edit the app code.

A FIDO CERTIFIED U2F AUTHENTICATOR

Your Ledger Unplugged can also become a U2F dongle for your Android phone. By installing the free Ledger U2F FIDO app from the Fidesmo store, your Unplugged will act as a secure U2F dongle for Google Authenticator. Watch our video below for a demontration of the feature.
