We're making the world of digital assets accessible and secure for everyone. 

Join the mission. 

Founded in 2014, Ledger is the global platform for digital assets and Web3. Over 20% of the world’s crypto assets are secured through our Ledger Nanos. Headquartered in Paris and Vierzon, with offices in UK, US, Switzerland and Singapore, Ledger has a team of more than 500 professionals developing a variety of products and services to enable individuals and companies to securely buy, store, swap, grow and manage crypto assets – including the Ledger hardware wallets line with more than 6 millions units already sold in 200 countries. 

At Ledger, we embody the values that make us unique: Pragmatism, Audacity, Commitment, Trust and Transparency. Hear from our employees how they shape the work we do here. 

Ledger has developed Ledger Live, an application to manage all your blockchain-backed assets. It's built in [React.js] (Electron on Desktop and React Native on Mobile) and supports multiple blockchains (coins & NFTs) as well as provides multiple services by integrating DApps and offering a SDK for 3rd parties to integrate. Of course, all this is backed by our hardware wallets which Ledger Live allows you to manage. 

This application is developed by several teams, each working on specific parts of the software. The Live Hub squad is responsible for building and maintaining the portfolio and account management UI flows.
