🛡️ Take Control of Your Digital Future: Security for DeFi & Web3

The world of Decentralized Finance (DeFi) and Web3 is exploding with innovation, offering unprecedented financial freedom and new ways to interact online. However, with self-custody comes a vital responsibility: security. In a landscape riddled with hacks, scams, and platform failures, protecting your assets is non-negotiable.

Welcome toLedger.com/Start—your starting point for securing your crypto, NFTs, and access to the decentralized world. Ledger provides the essential foundation you need to explore DeFi, interact with dApps, and manage your digital identity with peace of mind.

🔒 The Ledger Security Model: Uncompromised Protection

Ledger devices aren't just wallets; they are Secure Signers. They are built with a unique, multi-layered security architecture designed to keep your most critical assets—your private keys—completely offline and isolated from internet-connected threats.

Hardware-Level Security: The Secure Element

The core of every Ledger device is an EAL-certified Secure Element (SE) chip—the same technology used in passports and credit cards. This tamper-proof chip is specifically designed to:

  • Generate and Store Private Keys: Your Secret Recovery Phrase is generated offline within the SE chip and never leaves the device, making it inaccessible to online hackers.
  • Isolate Transactions: All transaction signing happens inside the SE chip, protecting your keys even if your computer or smartphone is infected with malware.

The Power of Clear Signing

Navigating DeFi means interacting with smart contracts, which often requires giving permissions or "approvals." A common attack vector involves "blind signing," where you authorize a malicious transaction without knowing the true details.

Ledger combats this with Clear Signing, a critical feature available through the Ledger Live companion app:

  • When you initiate a DeFi transaction (like a swap, stake, or dApp interaction), the Ledger device uses its secure screen to display the full, human-readable details of the transaction.
  • You must physically verify and approve these details on the device itself using its buttons or touchscreen. This ensures you know exactly what you are signing before your private key is used.

If the details on your Ledger screen don't match your intentions, you simply reject the transaction. Your assets remain safe.

🔑 Your Keys, Your Crypto: True Self-Custody

Ledger embodies the ethos of self-custody: you are the sole owner of your crypto. This means no centralized exchange or third party can freeze your funds, seize your assets, or prevent you from transacting.

  • Offline Storage: Your private keys are stored in a cold storage environment (the Ledger device), far away from the online vulnerabilities that affect "hot" wallets.
  • PIN Protection: Every Ledger device is protected by a PIN code. A thief with physical access cannot use the device without this code, and multiple incorrect attempts will wipe the device, keeping your keys secure.
  • The Secret Recovery Phrase: This 24-word phrase is the ultimate backup. It allows you to restore access to your assets on any new Ledger device if your original one is lost, stolen, or damaged. Never share this phrase with anyone and store it offline, securely.

🌐 Confidently Explore DeFi and Web3

The Ledger Live app is your secure gateway to the decentralized world, seamlessly integrating your Ledger device for safe Web3 exploration.

  • Connect to dApps: Ledger Live allows you to safely connect to various dApps and decentralized services. By integrating directly with your hardware wallet, you mitigate the risk of phishing or connecting to malicious sites.
  • Buy, Swap, and Stake: Manage your portfolio directly within the secure Ledger ecosystem. Use built-in services to buy crypto, swap assets across chains, and stake your coins to earn rewards—all while your private keys remain secured offline.
  • Manage All Your Assets: From Bitcoin and Ethereum to a huge range of tokens, NFTs, and altcoins, Ledger supports 15,000+ crypto assets. Manage them all in one place with the highest level of security.
