21650552497– Security Guide for Participating in Airdrops

1. Use a dedicated wallet for Airdrops

Do not use your main wallet.

Create a new wallet (like MetaMask or Trust Wallet) solely for Airdrop purposes.

2. Never share your private key

Any entity asking for your private key is 100% a scam.

Keep your private key in a safe place and do not share it with anyone.

3. Verify the source of the Airdrop

Only participate in Airdrops from trusted projects.

Check the official website and social media accounts.

4. Do not trust shortened or unknown links

Verify links before clicking on them.

Use tools like VirusTotal to scan links.

5. Beware of apps and websites that request unjustified permissions

Do not link your wallet to suspicious websites.

Do not sign any suspicious or unclear transactions.

6. Beware of "fake" Airdrops on Telegram and Twitter

Do not click on links from untrusted accounts.

Do not trust accounts that resemble official accounts (carefully check the blue tick and username).

7. Use a separate email

Create a separate email for Airdrop registrations to avoid spam and hacking.
