What is a Ledger or Hardware Wallet?. A hardware wallet is a device that isolates private keys from the internet and signs transactions securely.
How it works
When you initiate a transfer, the device shows details and asks you to confirm; only the signature leaves the device.
Why it matters
Cold storage dramatically lowers common attack paths and is recommended for long‑term holdings.
Common pitfalls
- Buying from unofficial resellers
- Not verifying addresses on the device screen
- Losing the device and seed phrase backups
Quick example
You move long‑term holdings to a hardware wallet and test a withdrawal before storing it securely.
