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

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

Desktop Application (Windows, macOS, Linux)

Ideal for initial device setup, firmware updates, and maintaining an isolated, stable environment for long-term portfolio management. Connects via USB.

Mobile Application (iOS, Android)

Perfect for daily balance checks, quick transaction approvals, and managing modern Ledger devices (Nano X, Stax) using secure Bluetooth connectivity.

⬇️ Section 2: Mandatory Secure Download and Integrity Check

To avoid malicious software, you must adhere strictly to the official download protocol for both desktop and mobile applications.

2.1 Secure Download Checklist

**Official Website Entry:** For desktop, manually navigate to https://www.ledger.com/ledger-live. Do not click search engine ads.
**App Store Verification (Mobile):** For mobile, download only from the official Apple App Store or Google Play. Verify that the publisher is listed precisely as **"Ledger"**.
**Installation Integrity (Desktop):** After downloading the desktop installer, advanced users should verify the file's **cryptographic hash (checksum)** against the value published on the Ledger website to confirm the file has not been corrupted or tampered with.

ABSOLUTELY CRITICAL: RECOVERY PHRASE SAFETY! The Ledger Live App will **NEVER** under any circumstance, ask you to type, paste, or input your 24-word Recovery Phrase into your computer, phone, or the application interface. If any screen prompts this, it is an attack; immediately close the app and disconnect your device.

🔑 Section 3: Ledger Live Guided Setup and Genuine Verification

The Ledger Live App takes you through the crucial steps of initializing your device, ensuring a secure foundation for all your crypto assets.

3.1 The Critical Genuine Check

Upon connection, Ledger Live performs the essential **Genuine Check**. This cryptographic verification confirms that your Ledger device is authentic and running the genuine, secure Ledger firmware. This built-in security layer protects you from using counterfeit devices right from the start.

3.2 Secure Key Management Workflow

The application facilitates the generation and backup of your master key, strictly following the cold storage rules:

**PIN Code:** Ledger Live prompts you to set a PIN (4-8 digits) directly on your device screen.
**Recovery Phrase Generation:** The 24-word phrase is generated by the device's certified random number generator and displayed **ONLY on the device’s screen**.
**Offline Backup:** You record the phrase on the physical Recovery Sheet. Ledger Live guides the subsequent verification, which is done physically on the device.

3.3 Firmware and Coin App Management

Use the 'Manager' section in Ledger Live to safely update your hardware. The application ensures all firmware updates are cryptographically signed by Ledger and installed only after verification by the device's Secure Element.

💰 Section 4: Secure Portfolio Management and Transaction Protocol

Whether using the desktop or mobile app, Ledger Live enforces the highest level of security for daily operations—the **What You See Is What You Sign (WYSIWYS)** protocol.

4.1 On-Device Verification (WYSIWYS)

This principle ensures that the final, critical details of any transaction are reviewed on the device itself, which is protected from external hacking:

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

This step makes it impossible for malware on your host device (PC or mobile) to secretly alter the transaction recipient or amount without your knowledge.

🚀 Section 5: Accessing Web3 and Integrated Services

Ledger Live is your verified gateway to the decentralized world, offering secure access to advanced crypto functionalities via its integrated services.

**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 the 'Discover' section and WalletConnect feature to securely interact with DeFi protocols and NFT marketplaces. Ledger Live routes smart contract approval requests to your device for signature, protecting you from malicious contracts.
**Universal Asset Support:** Manage the full spectrum of your crypto portfolio—from major coins to ERC-20 tokens and NFTs—all within the unified Ledger Live dashboard.
