#加密安全须知

### **Encryption Security Guidelines: Protect Your Digital Assets**

#### **1. Private Key & Recovery Phrase Security**

- **Never Share**: Private key = asset ownership; leakage = funds stolen.

- **Offline Storage**: Write by hand or save in a hardware wallet, avoid screenshots/cloud storage.

- **Recovery Phrase Backup**: Distribute in multiple places (like a safe + trusted relatives) to prevent loss.

#### **2. Wallet Security**

- **Use Cold Wallets**: Store large assets in hardware wallets like Ledger/Trezor.

- **Verify Wallet Address**: Check the first and last characters before transferring to prevent malware tampering.

- **Beware of Fake Wallets**: Only download from the official website, avoid third-party app stores.

#### **3. Transaction & Phishing Prevention**

- **Be Cautious with Links**: Phishing sites impersonate exchanges/airdrops; manually enter the URL to confirm.

- **Disable “Unlimited Authorization”**: Regularly revoke DApp's smart contract permissions (e.g., Revoke.cash).

- **Two-Factor Authentication (2FA)**: Avoid SMS verification; use Google Authenticator/Authy instead.

#### **4. Anti-Hacker & Social Engineering**

- **Isolated Environment**: Use dedicated devices for transactions; do not install unrelated software.

- **Anonymous Habits**: Refuse private messages on Discord/Telegram to prevent impersonation scams.

- **Beware of “Insider Information”**: 99% of Twitter/X “lotteries” are scams.

#### **5. Emergency Preparedness**

- **Simulate Recovery**: Test if the recovery phrase can retrieve the wallet to avoid mistakes in emergencies.

- **Will Planning**: Inform trusted individuals about the inheritance method of your crypto assets.

**Core Principles**: **Do not trust easily, do not be greedy, do not be lazy in verification**. Blockchain transactions are irreversible, and safety is no trivial matter! 🔐
