Fake airdrops and QR codes: the hidden signing risk
A free-token offer can lead to access requests or malicious transactions.

The short answer
The phrase 'free airdrop' does not make a link safe. Fraudsters use social-media posts, copied accounts and QR codes to take users to sites that request wallet access, signatures or credentials. A trusted person's account may itself be compromised, so a familiar sender is not enough.
What to check and preserve
Verify any announcement from the project's independently located official channels. Read every wallet prompt and do not sign an unexplained transaction. If you already interacted, record the site, message, approval or signature details and any resulting transaction. Follow verified wallet guidance on suspicious access rather than revisiting the offer.
Limits and important distinctions
A security review is not the same as a recovery. No legitimate token claim needs your seed phrase. Be wary of a second website claiming that it can reverse the first interaction if you connect the same wallet or pay a verification fee.
Checklist
- Verify the offer independently.
- Do not scan unsolicited QR codes.
- Preserve the exact wallet prompt if available.
- Never enter a seed phrase to claim a token.
