#加密安全须知 encryption security must start from private key management, phishing prevention, and device protection. Private keys and mnemonic phrases must be stored offline (such as in hardware wallets or paper backups) to avoid digital device leaks. Enable two-factor authentication (2FA) and be wary of phishing, avoiding clicking on suspicious links or authorizing third-party applications. Choose cold wallets to store long-term assets, while hot wallets should only be used for daily transactions, and regularly update wallet software to fix vulnerabilities. Verify addresses before transactions to avoid clipboard hijacking or screen theft risks. Important data should be encrypted and backed up, and public Wi-Fi should be disabled for sensitive operations.
