What is a Hardware Wallet?
A hardware wallet is a physical device designed to securely store the private keys to your cryptocurrency funds. Unlike software wallets on internet-connected devices, a hardware wallet keeps your keys in an isolated, offline environment. This means that when you want to make a transaction, you must physically connect the device to sign it, ensuring your private keys never leave the secure chip inside the wallet. This method protects your assets from online threats like hackers and malware.
Ledger's Security Architecture
Ledger devices are built with multiple layers of security to provide robust protection for your digital assets.
- Secure Element Chip: This is the same type of chip found in credit cards and passports. It is a tamper-resistant platform capable of securely hosting applications and protecting confidential data, like your private keys[citation:9].
- Proprietary Operating System (Ledger OS™): Ledger devices run on a custom-built OS that isolates cryptographic operations within the Secure Element, adding another layer of defense[citation:9].
- Trusted Display: The screen on your Ledger device shows you the details of the transaction you are about to sign. This allows you to "Clear Sign" the transaction, verifying all details on the secure device itself before approving, which helps avoid costly mistakes and scams[citation:9].

Getting Started with Your Ledger
Setting up your Ledger device is a straightforward process designed with security in mind from the very first step.
- Download Ledger Live: Start by downloading the official Ledger Wallet™ app (formerly Ledger Live) on your smartphone or desktop[citation:8]. This all-in-one app allows you to manage your crypto, check balances, and install apps on your Ledger device.
- Initialize Your Device: When you first set up your Ledger, it will generate a unique 24-word Recovery Phrase. This phrase is your master key. Write it down on the provided card and store it in a safe place—never digitally[citation:7]. This single phrase backs up all the accounts derived from it.
- Install Blockchain Apps: Use Ledger Live to install small applications for each cryptocurrency you want to manage (e.g., Bitcoin, Ethereum). These apps allow your Ledger device to sign transactions for that specific blockchain.
- Manage Your Crypto: You can now securely receive, send, and even grow your assets through staking, all by confirming actions on your Ledger device[citation:5].
