- Related: ledger-live-mobile
- Backed by: ledger-live-common
Ledger Live is a new generation wallet desktop application providing a unique interface to maintain multiple cryptocurrencies for your Ledger Nano S / Blue. Manage your device, create accounts, receive and send cryptoassets, ...and many more.
Architecture
Ledger Live is an hybrid desktop application built with Electron, React, Redux, RxJS,.. and highly optimized with ledger-core C++ library to deal with blockchains (sync, broadcast,..) via ledger-core-node-bindings. It communicates to Ledger hardware wallet devices (Nano S / Blue) to verify address and sign transactions with ledgerjs. Some logic is shared with live-common.
