Ledger Hardware Wallet: Upgrade Your Crypto Experience

Ledger Hardware Wallet uses "cold storage" technology, which is the most essential difference from software wallets. Specifically:

• Offline Private Key Storage: Your private keys are permanently stored in the secure chip built into the Ledger device, never touching the internet, so hackers cannot steal them through network attacks.
• Military-grade Security Chip: Ledger uses CC EAL5+/EAL6+ certified Secure Element, which is the same level of security technology used in bank cards and passports.
• Physical Transaction Confirmation: Every transaction requires physical button confirmation on the Ledger device. Even if your computer is hacked, assets cannot be transferred without your manual operation of the Ledger.
• Tamper-proof Design: Ledger devices have anti-tamper protection. Any physical cracking attempt will cause the chip to self-destruct, protecting your private key security.

In comparison, software wallets store private keys on internet-connected devices, making them vulnerable to theft through viruses, trojans, phishing attacks, etc. Choosing a Ledger hardware wallet means choosing the highest level of crypto asset protection.

No, it won't be lost! This is one of the most concerning questions for Ledger users. Remember: Your cryptocurrency is stored on the blockchain, not in the Ledger device. The Ledger only keeps the "key" (private key) to access these assets.

When setting up Ledger for the first time, the device generates a 24-word recovery phrase (seed phrase). As long as you properly keep these 24 words:

• You can fully recover all assets on a new Ledger device
• You can recover on other BIP39 standard compatible wallets (such as MetaMask, Trust Wallet, etc.)
• Not affected by Ledger company's operational status. Even if Ledger company goes bankrupt, your assets remain safe

⚠️ Important Reminder: The seed phrase is the only credential for recovering assets! Please write it down with pen and paper and keep it in a secure physical location. Never take photos, screenshots, or store it on any internet-connected device.

Getting the device alone cannot steal assets. Ledger has multiple security protection mechanisms:

• PIN Code Protection: Every time you use Ledger, you need to enter a 4-8 digit PIN code. Without the correct PIN, you cannot access the device.
• Error Lockout: After 3 consecutive incorrect PIN entries, Ledger will automatically reset to factory settings, and the private keys in the device will be cleared.
• Anti-physical Cracking: The secure chip has anti-tamper protection. Any brute force cracking attempt will cause the chip to self-destruct.

However, if an attacker simultaneously obtains your Ledger device and PIN code (or seed phrase), they may be able to transfer your assets. Therefore, we recommend:

• Set a complex PIN code, avoid using birthdays, repeated numbers, or other simple combinations
• Do not keep the PIN code together with the Ledger device
• If the device is lost, immediately use the seed phrase to transfer assets to a new wallet

Ledger's Bluetooth connection is secure. Many users worry that Bluetooth could be a security vulnerability, but Ledger's design ensures absolute security of Bluetooth transmission:

• Private Keys Never Transmitted: Your private keys and seed phrases are never transmitted via Bluetooth; they only exist in the secure chip inside the Ledger device.
• End-to-end Encryption: Bluetooth only transmits public data (such as transaction requests) and uses end-to-end encryption.
• Physical Confirmation Mechanism: All transactions must be confirmed on the Ledger device screen and approved with physical button presses. Data intercepted via Bluetooth cannot be used to execute transactions.
• Pairing Verification: During the first Bluetooth pairing, Ledger will display a verification code that requires user confirmation to prevent man-in-the-middle attacks.

In short, even if hackers intercept the Bluetooth signal, without your physical confirmation on the Ledger device, they can do nothing. This is the core security concept of Ledger hardware wallets.

Buying authentic Ledger products is very important, as counterfeit products may lead to asset theft. Please note the following:

• Official Channel Purchase: Purchase from the Ledger official website or authorized dealers, avoid second-hand platforms and sellers from unknown sources.
• Check Packaging Integrity: Authentic Ledger packaging uses tamper-evident design. If you find signs of opening, damaged plastic sealing, please return it immediately.
• Device Has No Presets: ⚠️ This is the most critical point! Brand new Ledger devices never come with pre-set seed phrases. If you receive a device with a pre-written recovery phrase card, this is definitely a scam!
• Ledger Live Verification: For first-time use, verify device authenticity through the official Ledger Live application. The software will check if the firmware has been tampered with.
• Verify Serial Number: The device serial number should match the one on the packaging box. You can contact Ledger official customer service to confirm.

If you have any questions about the purchase channel, please contact our customer service team, and we can help you verify authenticity.
