#币安安全见解 Mnemonic Phrase and Private Key Lifecycle Management

Generation Phase: Use standard algorithms such as BIP-39 to generate mnemonic phrases through offline devices, avoiding the randomness vulnerabilities of online generation tools (such as rainbow table attacks); it is recommended to use open-source wallets (like Trust Wallet) to ensure the security of the toolchain.

Storage Phase: Implement hot and cold wallet separation, with over 90% of assets stored in hardware wallets (like Ledger) and small assets using hot wallets; employ multi-layer encryption (like VeraCrypt) and decentralized backups (safes, trusted friends, cloud encryption) to reduce single-point risks.

Emergency and Inheritance: Ensure the safety of large assets through multi-signature wallets (requiring 2 or more private key authorizations), or use smart contracts to set inheritance conditions, avoiding asset freezing risks.

Risk Control System

Transaction Verification: Strictly verify BEP-2 address formats to prevent address tampering attacks; support multi-dimensional identity authentication such as 2FA and U2F, and disable SMS verification to reduce credential theft risks.

Security Audit: Conduct regular code audits, penetration tests, and third-party security assessments; for example, vulnerabilities found in Trust Wallet in 2024 have been promptly fixed to reduce backdoor risks.
