Common Airdrop Scams and Warning Signals

Traffic Scam: Requires following on Twitter, joining Telegram/Discord groups, which actually accumulate followers for marketing accounts, later changing names to promote scam information.

Authorization Trap: Induces users to authorize smart contracts, leading to the transfer of wallet assets. For example, the Zepe airdrop scam, where users lost assets due to authorizing DEX trades.

Private Key Leakage: Requests input of private keys or seed phrases to 'claim' airdrops, directly leading to wallet theft.

Fake Official Website: Masquerades as an official airdrop page, inducing users to connect wallets or transfer funds.

Anti-Scam Strategies

Verify Projects: Check if the project is listed through CoinGecko or CoinMarketCap, and search for team backgrounds and investment information.

Inspect Contracts: Use Etherscan or Sui Explorer to analyze smart contracts, confirming whether they are open source and free of malicious code. PeckShield recommends regularly revoking authorizations for unused DApps.

Small Amount Testing: Use a new wallet to participate in airdrops, keeping only a small amount of test coins to avoid risks to the main wallet.

Avoid Private Key Leakage: Never share seed phrases or private keys, and ignore any prompts asking for sensitive information.

Use Security Tools: Install Wallet Guard or Scam Sniffer browser plugins to detect malicious websites and contracts.

3. Secure Operational Habits

Hardware Wallet: Use Ledger or Trezor to store large assets, and only use hot wallets for participating in airdrops.

Multi-Factor Verification: Enable 2FA (Google Authenticator) to protect exchange and wallet accounts.

Be Cautious of High Returns: If an airdrop promises 'high-value tokens', it is likely a trap, proceed with caution. #空投防骗手册
