#加密安全须知

Four-dimensional protection system:

① Wallet selection: Store 70% of assets in a hardware cold wallet, leave only 30% liquid funds in a hot wallet;

② Private key management: Use Shamir secret sharing encryption, disable screenshots/cloud backups;

③ Exchange protection: API key binding to IP whitelist + read-only permissions, biometric second verification must be enabled;

④ On-chain interaction: Contract authorization limit ≤ 0.1ETH, use Revoke.cash for weekly scans (BSC chain phishing attacks caused a loss of $22 million in June).
