Airdrops provide free tokens to promote blockchain projects but carry the risk of fraud. Use a separate non-custodial wallet (e.g., MetaMask), never share private keys — only public addresses. Research projects through official websites, whitepapers, and team qualifications. Avoid suspicious links; check URLs on CoinMarketCap. Ignore tokens from unknown wallets; verify on Etherscan/BscScan. Use secure connections, enable 2FA, avoid FOMO tactics. Detect fraud with promises of high-value tokens, fake social media, phishing emails, or suspicious smart contracts. Find airdrops on airdrops.io or Bankless Airdrop Hunter, confirming eligibility through official channels. Use minimal funds, bookmark reliable sites, report fraud. Airdrops may be taxable; consult a tax advisor. Prioritize security, conduct thorough research, and only risk what you can afford to lose. This is not financial advice; consult professionals.
