What is Fake Airdrop?
Reviewed 2026-06-25
Definition: A fake airdrop lures you to a site that asks you to connect a wallet or sign a transaction to claim free tokens, then drains your wallet instead. Real airdrops send tokens directly to eligible addresses — they never require you to sign an approval or pay a fee to receive them.
How it works
Attackers announce fake airdrops on social media, via DMs, and through copycat sites that look identical to real projects. The claim process asks you to connect your wallet and sign a transaction — which is actually a token approval or a Permit2 signature that grants the attacker's contract full spending rights. Some variants request a small 'gas fee' payment to release the airdrop, which is simply theft. Timing often coincides with real airdrop news to exploit excitement and reduce caution.
How to protect yourself
Verify any airdrop claim through the project's official website — find it via a bookmark or a search, never via a link in a DM or social post. Check the URL before connecting. If a claim site asks you to sign any approval or pay a fee, stop — real airdrops do not work that way.
Frequently asked questions
How do I know if an airdrop is real?
Find the announcement on the official project website or verified social accounts — accessed directly, not via a link someone sent you. Real airdrops are announced through official channels and do not require approvals or fees to claim.
What should I do if I already connected my wallet to a fake airdrop site?
Check your token approvals immediately and revoke any approval you did not intentionally grant. If you signed a Permit2 or similar signature, the approval may already be active — revoke and consider moving assets to a new wallet.
Do I need to pay gas to receive an airdrop?
Receiving tokens sent to your address costs the sender gas, not you. If a site asks you to pay gas or a fee to receive an airdrop, it is a scam.
