I. Core Principle: The private key is life.
Offline Storage: Private keys/mnemonic phrases must be handwritten on paper and stored in a fireproof safe or other physically secure locations. Do not take screenshots, store in the cloud, or send to others. Beware of Social Traps: Official teams will not actively ask for private keys; any request for mnemonic phrases via private messages under the guise of 'customer service' is a scam.
II. Wallet Usage Safety Download Verification: Download wallets through official websites or app stores, be wary of search engine ads and third-party links. Check that developer information matches the official website (e.g., MetaMask developers should be 'ConsenSys'). Prefer Hardware Wallets: Use hardware wallets like Ledger/Trezor for large assets, and never expose private keys to the internet. Always purchase through official channels.
Regularly Check Authorizations: Use tools like Debank to scan smart contract authorizations and promptly revoke unlimited authorizations for idle DApps.
III. Transaction Protection Measures: Use Multi-signature Mechanism with Caution: Do not enable multi-signature unless necessary; if used, ensure all signing devices are independently secure. Regularly check account permissions on chains like TRON (whether Owner/Active permissions are abnormal). Small Amount Testing Principle: For first-time transfers to a new address, send a test amount of 0.1U first, and confirm receipt before making larger transactions.
Phishing Identification Techniques: Verify domain details, install anti-phishing plugins like Scam Sniffer.
IV. Equipment and Environmental Safety Special Equipment: It is recommended to prepare a clean phone/computer without social media software specifically for operating wallets. Network Protection: Do not use public WiFi for transactions, use a paid and trusted VPN service. Antivirus Software is a Must: Install Kaspersky/AVG and keep it updated, regularly perform a full scan.
Immediately transfer remaining assets to a new wallet. Use blockchain explorers like Tronscan to check permission change records. Contact security companies like Slow Fog for on-chain tracking. Mark the stolen address as 'stolen' to alert exchanges to freeze related funds.
Final Reminder: The Web3 world has no 'absolute security'. It is recommended to adopt a 'cold and hot separation' strategy; daily use wallets should only store small amounts, just like not carrying all cash when going out in real life. Stay alert to security dynamics, and regularly review authoritative materials like the (Slow Fog Security Guide) for long-term safety.
