Ledger is a French company launched in 2014 by eight experts with complementary backgrounds in embedded security, cryptocurrencies and entrepreneurship, united around the idea of creating secure solutions for blockchain applications. We now have over 170 employees in Paris, Vierzon, New York and San Francisco.

We developed a distinctive operating system (OS) called BOLOS, which we integrate either to a secure chip for the Ledger wallet line, or to a Hardware Security Module (HSM) for various enterprise solutions.

We aim at securing the new disruptive class of crypto assets: Financial assets like cryptocurrencies or Initial Coin Offerings (ICOs), Data assets like sensors, Internet of Things (IoT) devices or machine to machine, and Digital identities like second factor authentication or passwordless login.

Ledger hardware wallets: We designed several wallets: the light Ledger Nano S (and its new version the Ledger Nano X) and the touchscreen Ledger Blue, which can both support directly 23 cryptocurrencies, and dozens more via third party applications.


We offer fully customizable infrastructure solutions safeguarding crypto assets for Banks, Hedge Funds and High Net Worth individuals. We also work together with big players in various industries on blockchain use cases.
