The most expensive click in crypto is often a fake claim button. Scammers clone real airdrop announcements, buy ads, and build near-perfect copies of claim pages, all designed to get you to connect your wallet and sign a transaction that drains it. The good news is that fake sites almost always leave clues, and learning them takes less time than recovering from a theft.

This guide lists nine red flags to check before you connect a wallet to any airdrop site. No single flag proves a site is fake, but two or three together should stop you cold. When in doubt, close the tab and find the official link from the project's own channels.
