The core of Web3 is "users control their assets," but this also means all responsibility is on you—no bank can freeze your account, and no customer service can help recover stolen assets. This guide helps you avoid the most common pitfalls.

💎 Core principle: Don't trust anyone

· Private keys/mnemonics are ownership: whoever has them owns the assets. Never tell anyone in any form, including screenshots, cloud storage, or sending to "customer service."
· Make backups: write them on a metal plate or paper, and store separately. Consider using multi-signature wallets (requiring multiple approvals) or hardware wallets (private keys stored offline) to manage large assets.

⚠️ Common threats and responses

· Authorization phishing: the most dangerous scam. After you click "Connect Wallet - Confirm Signature," the other party can transfer your authorized assets. Response: regularly revoke suspicious authorizations with tools; be cautious of links claiming "free mint" or "large airdrops."
· Fake wallets/fake apps: downloading counterfeit applications can directly steal your private keys. Response: only download from official websites or official app stores; verify download counts and reviews.
· Pixiu tokens: tokens that can only be bought but not sold. Response: use tools to detect, or only trade mainstream tokens.
· Perm black hole: if set to unlimited during approval, the project team can transfer your assets without limit. Response: choose a limited amount when authorizing; after use, manually set it back to zero.

📱 Operation habit checklist

· No interaction: never connect your mnemonic/mnemonic phrase or private key online.
· No contracts: participate with small amounts, set up separate addresses, verify contract code.
· No blind signing: review the content carefully before signing; reject garbled or unlimited authorizations.
· Regular checks: review authorizations weekly; use multi-signature or cold wallets for large assets.
· Quick response: if you find suspicious authorizations, cancel immediately and transfer remaining assets.

Remember: your security depends on the weakest link. Stay skeptical, even of yourself.
