Core Security Architecture

Ledger wallets are built with **military‑grade security** in mind. Each device uses a certified Secure Element chip (CC EAL5+), the same level used in passports and banking cards. This chip isolates private keys from the internet and external access. :contentReference[oaicite:0]{index=0}

Ledger’s custom operating system, BOLOS, ensures apps run in isolation. Combined with a **secure screen** controlled directly by the Secure Element, you always see accurate transaction details—so what you see is what you sign. :contentReference[oaicite:1]{index=1}

Offline Key Storage & PIN Protection

Your private keys never leave the Ledger device. All transaction approvals happen physically on the hardware device, not on your computer or phone. This means even if your computer is compromised, your crypto remains safe. :contentReference[oaicite:2]{index=2}

Each device is protected with a PIN. Entering the wrong PIN resets or locks access—this helps prevent unauthorized access in case of loss or theft. :contentReference[oaicite:3]{index=3}

Multi‑Asset & NFT Support

Ledger supports thousands of coins and tokens. Whether it’s Bitcoin, Ethereum, Solana, or ERC‑20/BEP‑20 tokens, your assets can be managed with one Ledger device. :contentReference[oaicite:4]{index=4}

Additionally, Ledger Live now includes NFT viewing and management for networks like Ethereum and Polygon. You can view NFT galleries, inspect metadata, and transfer NFTs safely—always confirming on the hardware. :contentReference[oaicite:5]{index=5}

Staking & DeFi Compatibility

Earn passive rewards by staking supported assets directly via Ledger Live while retaining full control. Assets like Ethereum, Tezos, Polkadot, Cosmos, and more are supported. Confirmation still happens on the hardware device. :contentReference[oaicite:6]{index=6}

Ledger hardware works with many DeFi dApps safely via integrations and Ledger Live’s Discover or through third‑party wallets. Even when interacting with complex smart contracts, your seed phrase and private keys remain protected offline. :contentReference[oaicite:7]{index=7}

Device Models & Features

Ledger offers multiple device models, including the Ledger Nano S Plus, Nano X, and newer ones with features like Bluetooth, USB‑C, larger storage, etc. Choose based on your asset count, mobility needs, and desired features. :contentReference[oaicite:8]{index=8}

All models share the same fundamental security features: Secure Element, BOLOS, PIN protection, recovery phrase. Higher‑end models add convenience like wireless or higher capacity for apps. :contentReference[oaicite:9]{index=9}

How Ledger Hardware Wallets Work in Practice

1. Purchase only from the official Ledger store or trusted resellers to avoid tampered products.
2. Unbox and inspect the device for seals and authenticity; initialize it using Ledger Live.
3. Set a PIN, generate and back up your recovery phrase in multiple safe, offline locations.
4. Install only the blockchain apps you need via Ledger Live; remove unused ones.
5. When sending crypto or NFTs, always verify the address and details on the device screen.
6. Keep firmware and Ledger Live app updated; Ledger’s security teams (including the Ledger Donjon & Attack Lab) regularly perform audits and respond to threats. :contentReference[oaicite:10]{index=10}
7. Store your recovery seed offline—consider metal backups; never store seed phrases digitally or share them.

Risks & How Ledger Mitigates Them

• **Phishing and fake software** – Ledger warns users to download apps only from ledger.com and verifies device authenticity. :contentReference[oaicite:11]{index=11}
• **Physical attacks** – Secure Element chips are certified and tamper‑resistant. BOLOS and Secure Screen help mitigate physical or firmware‑level exploits. :contentReference[oaicite:12]{index=12}
• **Blind signing danger** – Always review transaction data on device screen; Ledger Live supports “Clear Signing” so you see human‑readable transaction info. :contentReference[oaicite:13]{index=13}
• **Recovery phrase exposure** – Ledger’s design ensures seed stays with user; features like passphrase add extra security. :contentReference[oaicite:14]{index=14}
