To secure your crypto wallet while participating in airdrops, use a separate new wallet solely for these purposes. Never share your seed phrase or private key—no legitimate project will require this. Avoid suspicious links and downloads. Verify the authenticity of the project through official sources: website, Twitter, CoinMarketCap, etc. Do not grant access to tokens without understanding the consequences. Use extensions like Revoke.cash to check permissions. Always be cautious—scammers often disguise themselves as legitimate projects.
