Ledger makes hardware wallets, also described as signers. Their purpose is to keep private-key operations on a separate physical device while a companion application communicates with blockchain networks. Cryptocurrency balances remain on-chain; the device does not contain physical coins.
How hardware signing works
Ledger describes its devices as storing keys and signing transactions in a Secure Element chip. A connected app prepares a transaction, the user reviews it on the device, and the device produces a signature. The app can then broadcast that signed transaction.
Private keys remain inside the device
A hardware wallet is designed to sign transactions without exporting the private key to the connected computer. The device screen is therefore an important place to verify transaction details.
What the hardware cannot decide
A hardware wallet can protect key handling, but it cannot turn a malicious destination or risky application into a safe one. Review the recipient and transaction details on the device itself, and reject requests you do not understand.
Recovery still matters
Device loss and backup exposure are different problems. Recovery material can restore access, but someone else with that material may gain control too. Store it securely and follow the documentation for your device and chosen recovery setup. The pictured device is illustrative, not a buying recommendation.
The recovery phrase remains the ultimate backup
Hardware failure does not have to mean loss if the recovery phrase is intact. Anyone who obtains that phrase may be able to recreate the wallet, even without the original device.
