Prerequisites
- You have the target wallet address you need to query ready.
- You have located the official project announcement specifying the snapshot time or block height.
Don't panic if you see inconsistent airdrop eligibility results — always refer to the officially announced snapshot block height for verification. The page display is only a "front-end presentation" that may contain errors. A snapshot is a "screenshot" of the blockchain state recorded by the project team at a specific point in time, used to finalize the airdrop recipient list. The eligibility page you see is the project's converted queryable interface for that list; the on-chain contract verification logic is the only thing that truly determines whether you can claim airdrop tokens and how much you are eligible for.

Step 1: Locate the Officially Announced Snapshot Time / Block Height
[What to do]: Lock the exact snapshot time point from official project announcements.
[How to do it]: Check the project's X (Twitter), Discord or official website announcements to find the statement on snapshot time. Snapshots are usually anchored to a "block height", pointing to a fully packaged completed block.
Scenario A: The announcement specifies a clear block height (e.g. "Block #1,000,000") → Use this as the standard. Blockchain data is immutable, and anyone can independently verify the address state at this exact block height.
Scenario B: The announcement only lists a time (e.g. "2026-01-19 08:00 UTC") → Use this as the standard. Note that the snapshot time is not Beijing time by default, convert it to UTC time first.
[Completion Criteria]: You have a clear confirmed "snapshot block height" or "snapshot time", and know its corresponding UTC timestamp.
Step 2: Use Block Explorer to Bypass Front-end Display Errors
[What to do]: Bypass the query page's cache or display bugs, directly verify your address's on-chain state at the exact snapshot moment.
[How to do it]:
Scenario A: You made transfers or other transactions after the snapshot → Query your address via Etherscan (or the block explorer for the corresponding chain), jump to the block height matching the snapshot moment, and check your balance at that exact time. Any operations made after the snapshot will not affect your eligibility status.
Scenario B: The page shows "Not eligible" but you are sure you meet the requirements → Refer to the Grass airdrop case: The Grass Foundation once stated publicly that the airdrop checker's displayed token allocation was "not the final result", and they were adjusting the system to reduce false negatives. Vana also experienced inaccurate eligibility queries due to excessive traffic, and ultimately delivered airdrops manually. Towns Protocol also had cases where "some eligible wallets could not see the claim entry due to display errors".
[Completion Criteria]: You have verified your address state on-chain at the snapshot moment, confirming whether the query page display is accurate.
Critical Risk Reminder: Do not give up immediately or transfer your assets just because the eligibility query page shows "Not eligible". Some projects have inaccurate displays caused by excessive traffic, front-end cache, or detection system adjustments. Eligibility is always determined by the on-chain snapshot data. If you already held the required assets before the snapshot, your eligibility remains valid even if the query page temporarily shows otherwise.
Step 3: Cross-Validate via Official Public List or Merkle Root
[What to do]: Confirm whether your address is included in the final list generated by the project team.
[How to do it]:
Scenario A: The project publishes a public list file or Merkle Root → Use the official provided tool or block explorer to verify that your address is included in the list. The Merkle Root is the unique "fingerprint" of the full list, and no web page can forge your valid eligibility.
Scenario B: The project has not released list details → Wait for the claim window to open, and take the on-chain claim result as the final standard. The claim result is subject to on-chain transactions; only a successfully executed transaction with incoming token records is the final confirmation.
[Completion Criteria]: You have cross-checked your address status through official channels, or waited for the actual claim window result.
Common Reasons for Misjudging Failure
Do not assume your effort is wasted just because the eligibility page shows "Not eligible" — in many cases the project's query system is still under adjustment. Another common mistake: you buy the required assets temporarily a few hours before the snapshot, but the transaction is not recorded due to on-chain confirmation delay. The snapshot records the "confirmed block state", not the time you initiated the transaction.
Post-Operation Validation Method
Use the block explorer query tool to look up your address, jump to the block height corresponding to the snapshot moment, and take a screenshot of your balance and holdings at that exact time. Cross-compare this screenshot with the snapshot requirements listed in official announcements one by one, instead of relying on the display of any third-party query page.

Next Step Actions
If the page display is mismatched but you confirm you meet all requirements, wait 1-3 days and query again. It usually takes a few hours to several days for project teams to fix display issues. If the claim window is already open but the front-end still shows you are ineligible, try to claim directly on-chain, and take the contract verification result as the standard — you will successfully claim if the contract verification passes. Recommended verification channel: The "Block Height Query" function on Etherscan block explorer.
