LEDGER LIVE APP® | OFFICIAL LEDGER MOBILE & DESKTOP APPLICATION

📱 Section 1: The Ledger Live Ecosystem and Core Security

Ledger Live App® is the mandatory, official software application that acts as the user interface for all Ledger hardware wallets (Nano S Plus, Nano X, Stax, etc.). It is designed to be a comprehensive and secure all-in-one crypto management platform, available seamlessly across desktop and mobile environments.

The core security principle of Ledger Live remains paramount: it is a read-only interface to the blockchain via the public keys derived from your device. **Your private keys are never stored, exposed, or requested by the Ledger Live software.** They remain permanently secured within the device’s **Certified Secure Element chip**, ensuring that a compromise of your computer or phone cannot lead to the theft of your funds.

Ledger Live: Desktop vs. Mobile Capabilities

Ledger Live offers full feature parity across both desktop and mobile platforms, enabling flexible management and secure connectivity:

⬇️ Section 2: Mandatory Secure Download and Integrity Check

Protecting your assets begins with ensuring you install the authentic, uncompromised Ledger Live application. Malicious clones are a constant threat, and only the official channels should be used.

2.1 Secure Download Checklist

1. **Official Website Entry (Desktop):** Always go directly to the source: https://www.ledger.com/ledger-live. Manually type the address and avoid clicking sponsored search results, which are often phishing traps.
2. **App Store Verification (Mobile):** For mobile devices, download only from the **official Apple App Store or Google Play Store**. Verify the developer is explicitly listed as **"Ledger"** before proceeding.
3. **Post-Installation Integrity:** After installation, especially on desktop, Ledger Live automatically performs a cryptographic verification check during setup to confirm the integrity of the software and the authenticity of your hardware.

🔑 Section 3: Ledger Live Guided Setup and Genuine Verification

The Ledger Live App guides you through the crucial steps of initializing your device, establishing the necessary security layers, and ensuring a secure connection.

3.1 The Genuine Check and Key Isolation

The first interaction between the App and your device involves mandatory security checks:

• **The Genuine Check:** This cryptographic challenge verifies that your device is authentic and running the genuine, secure Ledger firmware. This is your primary defense against counterfeit hardware.
• **PIN and Recovery Phrase:** Ledger Live facilitates the setting of the PIN and the generation of the 24-word Recovery Phrase. The app maintains the absolute security requirement: the phrase is displayed **ONLY on the device’s screen** and must be transcribed onto your physical Recovery Sheet.

3.2 Firmware and Coin App Management

The 'Manager' section in Ledger Live is the only secure location for maintenance. The App ensures all critical updates are handled securely:

1. **Firmware Updates:** Ledger Live downloads packages that are cryptographically signed by Ledger. The hardware verifies this signature before installation, preventing malicious firmware.
2. **Account Synchronization:** After installing the necessary coin applications (e.g., Bitcoin, Ethereum) via the Manager, Ledger Live uses the device’s public keys to securely scan the blockchain and display your balances and transaction history.

💰 Section 4: Secure Transaction Protocol and WYSIWYS Enforcement

Ledger Live enforces the highest level of security for daily operations—the **What You See Is What You Sign (WYSIWYS)** protocol—ensuring transaction details are confirmed on the isolated hardware screen.

4.1 On-Device Verification (WYSIWYS)

For every critical action, the final verification step is always performed on the trusted screen of the hardware device:

• **Receiving Addresses:** When Ledger Live generates an address, you **must visually compare** the address displayed in the application with the exact string displayed on your Ledger device.
• **Sending Funds:** The App prepares the transaction, but the complete, final details (recipient, amount, fee) are pushed to the Ledger device screen. You **must physically review and approve** these details on the device before the signature is generated.

This protocol ensures that malware cannot secretly alter the recipient address on your host device, as the true signing details are only visible on the secure Ledger screen.

🚀 Section 5: Accessing Web3 and Integrated Services Securely

Ledger Live is your verified gateway to the decentralized world, offering secure access to advanced crypto functionalities via its integrated 'Discover' section and native features.

• **Native Staking and Rewards:** Delegate Proof-of-Stake assets (e.g., ETH, SOL, ATOM) directly within the app, earning rewards while your private keys remain secured by your hardware.
• **In-App Swapping and Trading:** Securely buy, sell, and swap cryptocurrencies using vetted third-party providers integrated into Ledger Live. All fund movements associated with these services require hardware signature.
• **NFTs and dApp Connectivity:** Utilize Ledger Live's built-in WalletConnect feature to securely interact with DeFi protocols and NFT marketplaces. All critical smart contract approvals are routed to the device, requiring physical signature confirmation.
• **Portfolio Flexibility:** Manage the full range of supported crypto assets and visualize your overall portfolio value across multiple accounts and chains within the unified dashboard.
