How to qualify
Most airdrops reward past activity: using a protocol, bridging funds, providing liquidity or holding a token at a snapshot date. Projects rarely announce the rules in advance, which fuels airdrop farming.
Scams to avoid
Fake airdrop sites ask you to connect a wallet and sign a transaction that drains it. Random tokens appearing in your wallet can be bait. Only claim through links from the project's official channels and never share your seed phrase.
