18 Precautions for Novices Using Web3 Wallets：
Seed Phrase Safety: Keep seed phrases offline on paper or steel. Digital storage like screenshots risks permanent fund loss.
Hardware Wallets: For large asset amounts, use hardware wallets (Ledger/Trezor) to isolate private keys from online threats.
Phishing Prevention: Double-check URLs. Avoid links in DMs and emails; fake sites mimic MetaMask/Trust Wallet to steal keys.
Contract Verification: Review smart contracts before interacting. Tools like Etherscan's “Contract Checker” help dodge malicious code.
Token Approval Control: Regularly revoke unnecessary token allowances via Revoke.cash to prevent asset theft.
Transaction Testing: Send a small amount before large transfers to confirm wallet and address correctness.
Network Caution: Don't use public Wi-Fi for wallet access. Opt for VPNs or mobile data to fend off MITM attacks.
Wallet Lock: Set auto-lock and passwords/PINs for wallet apps to block unauthorized access.
Airdrop Awareness: Ignore unsolicited airdrops of fake tokens/NFTs that may lead to malicious contracts.
Address Verification: Cross-check contract addresses from official sources to avoid scams due to errors.
Gas Fee Knowledge: Understand gas mechanics and use trackers like GasNow to avoid overpaying in network congestion.
Dedicated Wallets: Have separate wallets for trading, NFTs, and holding to limit losses if one is compromised.
Signing Caution: Enable “Transaction Simulation” to preview contract actions and prevent hidden moves.
App Source: Download wallets only from official sites/app stores to avoid fake apps stealing keys.
Configuration Backup: Backup custom RPC settings and network details in case of device/app reset.
dApp Monitoring: Disconnect unused dApps from your wallet regularly and track permissions with tools.
Software Updates: Follow wallet developers' socials for security patches; outdated apps have vulnerabilities.
Key Privacy: Legitimate projects never ask for seed phrases or private keys. Report and block such requests.
