Ledger Live is the official companion application for Ledger hardware wallets providing account management, transaction signing, portfolio tracking, and access to third-party services. Ledger Live runs on desktop and mobile and stores account metadata locally while relying on the hardware device to keep private keys offline. :contentReference[oaicite:0]{index=0}
Responsible for user flows, account presentation, and communicating with the local device agent or USB endpoints. Runs as a native desktop app (Electron/AppImage) and as a mobile app.
The device's OS holds the seed and performs sensitive cryptographic operations (key derivation, signing). Ledger Live never exports private keys and delegates all signing to the device.
Ledger Live queries blockchain data via its chosen node providers and integrates third-party services (exchanges, staking providers) through defined connectors and APIs.
The UI communicates with the device using HID/USB/BLE transport protocols and verifies device responses before constructing signed transactions to be broadcasted by the user's chosen network provider.
Ledger exposes developer documentation and a device app submission flow for projects that want to add blockchain support to Ledger Live or build device apps. For blockchain integrations and submitting device apps, follow the developer docs and partnership process. :contentReference[oaicite:1]{index=1}
Ledger Live includes a Developer mode (opt-in) that exposes testing tools and additional menus for integration testing; enabling it is documented in the developer references. :contentReference[oaicite:2]{index=2}
// Example: pseudo-code to check an account via Ledger Live APIs (conceptual)
fetch('/api/blockchain/account?address=0x123...')
.then(r => r.json())
.then(account => console.log('balance', account.balance));
Private keys and seed phrases must never leave the secure element. Ledger Live treats the hardware device as the root of trust. Any UI or application asking for a seed phrase is malicious by design. Always download Ledger Live from official sources. :contentReference[oaicite:3]{index=3}
If you suspect a compromised app or OS (fake installers, prompt for seed phrase), disconnect the device, verify the installer from the official ledger.com pages, and contact Ledger support immediately. :contentReference[oaicite:4]{index=4}
Ledger Live surfaces release notes and an update mechanism. Administrators should test updates in a controlled environment (Developer mode) before broad deployment in managed settings. Users can read “What’s new” and release notes for details on each version. :contentReference[oaicite:5]{index=5}
Use Ledger’s official support pages for troubleshooting common issues, firmware upgrade instructions, and device recovery processes. Keep an eye on official release notes for firmware and Ledger Live changes that may affect integrations. :contentReference[oaicite:6]{index=6}
Recovery phrase backups must be stored offline, in multiple physical locations if necessary, and follow organizational policy for access control.
