#加密安全须知 Encryption Security Core Guidelines

• Private Key is Asset: Private keys / mnemonic phrases must never be leaked or stored on connected devices (such as screenshots sent via WeChat, stored in cloud notes). If lost, they cannot be recovered. It is recommended to write them down by hand on paper and store them in a safe place.

• Wallet Security:

◦ Download official wallets (such as MetaMask, Trust Wallet) and be wary of phishing apps (counterfeit icons, domains with many letters and few numbers).

◦ Do not click on unfamiliar links or scan codes to authorize wallets; avoid “signature authorization” to prevent asset theft (authorization gives operational permissions).

• Exchange Risks:

◦ Choose leading compliant platforms (such as Binance, Coinbase), enable 2FA (Google Authenticator/hardware wallet), and do not use the platform's default email verification codes.

◦ Do not store large amounts of assets for a long time; regularly transfer funds to personal wallets to guard against platform hacking or exit scams.

• Trading Caution:

◦ Test with small amounts before making large transactions, especially on decentralized exchanges (DEX); ensure the contract address is correct (counterfeit contracts often change suffix letters).

◦ Be wary of “high yield airdrops” and “private placement investments”; 99% are scams, as legitimate airdrops do not require prior transfers or staking of assets.

• Environmental Safety:

◦ Regularly antivirus devices, do not trade on public WiFi, and avoid browser plugins (such as wallet plugins) being tampered with.

◦ Use dedicated phones/computers for sensitive operations (transfers, withdrawals) to reduce the operation of multitasking software.

Core Principle: At all times, asset control remains in your hands. Stay vigilant against behaviors such as “actively requesting private keys,” “high return promises,” and “emergency transfers.”
