Most legitimate airdrop projects now let you check eligibility by pasting a public wallet address into a checker page. Your public address is safe to share because it only reveals on-chain history, which is already public, while your seed phrase and private keys must never be entered anywhere.

The reason this matters is that wallet-connection prompts are one of the most common attack vectors in crypto. A malicious site can ask you to sign a transaction that drains tokens or grants unlimited spending approval, and the damage happens in seconds.

Start from the project's own verified channels. Find the announcement on its official website, verified social account, or documentation, and follow the checker link from there rather than clicking links in direct messages, group chats, or search ads.

Once you have the official checker, paste your public address and read the result carefully. Eligible, not eligible, and claim window closed are all normal outcomes, and none of them require you to connect a wallet or sign anything at the checking stage.

If the checker says you are eligible, do not rush to claim. Verify the claim page separately, use a dedicated claim wallet funded only with enough for gas, read every signature prompt before approving, and revoke token approvals afterwards.

If the checker says you are not eligible, accept the result and move on. Scammers love to target disappointed users with fake second-chance claim pages, and no legitimate project asks you to pay a fee to unlock eligibility.

The most frequent mistake is checking with the wrong wallet. If you used several wallets across different protocols, check each one separately, because eligibility is tied to a specific address, not to you as a person. Keep a record of which wallet you used where, so a later checker result makes sense instead of confusing you.

Another mistake is trusting a checker result that appears before any official announcement. Scammers build fake checker pages that always report an eligible allocation, because that is the bait that pushes victims toward a malicious claim signature. A real checker is announced through official channels, matches the project's published criteria, and never asks you to pay or sign anything to view the result. If a checker shows an allocation that seems far larger than your activity justifies, treat it as suspicious and verify through a second official source before taking any further step.
