Every airdrop comes down to one moment. Before it, your activity still counts. After it, nothing you do changes the result. That moment is the snapshot.
An airdrop snapshot is a record of wallet balances or on-chain activity at a specific block or time. Projects use it to decide which wallets qualify for an airdrop and how many tokens each one receives. Anything you hold or do after the snapshot does not count toward that distribution.
Snapshots sit at the heart of almost every airdrop format. Understanding them helps you time your farming, avoid classic mistakes and spot fake urgency.

How an Airdrop Snapshot Works
A blockchain is a public ledger. Anyone can read what every wallet held or did at any past block. A snapshot simply freezes that picture at one chosen point.
The project picks a block number or a timestamp. It then pulls the data it cares about for every wallet at that moment. That could be a token balance, a trading volume or a points total.
From there, the team filters the list. Bots and sybil wallets get removed. The remaining wallets receive an allocation based on the rules.
The snapshot is not the payout. It only decides who gets paid. The tokens arrive later, usually at or after the TGE. Our guide on what TGE means in crypto explains how that launch day works.
The Main Types of Airdrop Snapshots
Snapshots come in a few flavors. Each one rewards something different.
Holder Snapshots
These reward wallets that hold a specific token at the snapshot block. This is the oldest format in crypto. Back in 2017, OmiseGO airdropped its tokens straight to ETH holders based on a single snapshot. No sign-ups, no tasks.
Exchanges still use this model today. Binance runs HODLer airdrops based on snapshots of BNB balances in its savings products. Hold the right asset at the right time, and the tokens appear.
Activity Snapshots
These look at what a wallet did, not what it held. Swaps, bridges, trades and liquidity all count. This is the engine behind retroactive airdrops.
Uniswap made this format famous in 2020. Every wallet that used the protocol before September 1 received 400 UNI. Most users had no idea a snapshot was coming. Our guide to what a retroactive airdrop is covers the biggest examples.
Points Snapshots
Modern campaigns mostly run on points. Each season ends with a snapshot of the leaderboard. Your share of total points then decides your share of the allocation. Read our explainer on what airdrop points are for the full breakdown.
Announced vs Secret Snapshots
Some projects publish the snapshot date in advance. Others keep it hidden until after it happens.
Announced snapshots are common for points seasons and exchange airdrops. You know the deadline and can plan around it.
Secret snapshots are the norm for retroactive drops. The team takes the snapshot quietly, then announces the airdrop weeks or months later. Arbitrum did this in 2023, rewarding activity from a snapshot users never saw coming.
Secret snapshots exist for a reason. When farmers know the date, they flood the protocol right before it. Hiding the date rewards real users instead of last-minute tourists.
Single, Multiple and Average Snapshots
Projects have gotten smarter about gaming. A single snapshot is easy to exploit. Buy the token the day before, qualify, then sell.
To fight that, many teams now use multiple snapshots. They sample balances at random points over weeks or months. Some calculate a time-weighted average balance instead.
The lesson is simple. Consistent activity beats a last-minute sprint. A wallet that stays active for months scores better than one that shows up the day before a snapshot. That patience is what separates a real airdrop hunter from a tourist. Our airdrop farming 2026 guide explains why long-term wallet behavior matters more than ever.
Snapshot vs Claim: The Timeline
Many beginners confuse the snapshot with the claim. They are separate steps, often weeks apart.
1. Activity period. You hold, farm or earn points.
2. Snapshot. The project records every wallet at one block.
3. Filtering and calculation. The team removes sybils and sets allocations.
4. Announcement and eligibility check. The project reveals who qualifies.
5. TGE and claim. Tokens go live and eligible wallets claim them.
Missed the news on a past drop? Retroactive claims often go unnoticed for months. Run your wallets through our airdrop eligibility checker to see what you may already qualify for.
Common Snapshot Mistakes
Moving tokens right before a holder snapshot. If your balance sits on an exchange that does not support the airdrop, it may not count. Check how the snapshot handles exchange balances first.
Buying just for the snapshot. Many traders pile in before a known snapshot. The token often pumps into the date and dumps right after. The airdrop can end up worth less than the price drop.
Assuming the snapshot guarantees a payout. Sybil filters and minimum thresholds still apply after the snapshot. Qualifying on paper is not the same as receiving tokens.
Falling for fake snapshot urgency. Scammers love “snapshot in 2 hours, connect now” messages. Real projects never need you to connect a wallet to be included in a snapshot. The blockchain already has your data.
Snapshot Also Means Something Else
You will also see “Snapshot” used for a DAO voting platform. Projects use it to run off-chain governance votes. Voting power there often comes from a token snapshot too, which explains the name.
That tool has nothing to do with airdrop eligibility on its own. When a project says “snapshot” in an airdrop context, it means the eligibility record.

Final Words
A snapshot is the moment an airdrop gets decided. Holder snapshots reward what you own. Activity snapshots reward what you did. Points snapshots reward where you ranked.
You rarely control when the snapshot happens. You do control how consistently your wallet shows up. Stay active, skip the last-minute sprints and never trust anyone who says you must act before a snapshot.

FAQ
What is a snapshot in a crypto airdrop?
A snapshot is a record of wallet balances or activity at a specific block. Projects use it to decide who qualifies for an airdrop and how much each wallet receives.
Do I need to do anything during a snapshot?
No. The blockchain records your wallet automatically. Anyone asking you to connect or sign something “for the snapshot” is running a scam.
Can I sell my tokens after the snapshot?
Yes. For a holder snapshot, your balance only needs to be there at the snapshot block. Check whether the project uses multiple snapshots first.
How do I know when a snapshot happens?
Announced snapshots appear on the project’s official channels. Retroactive snapshots are usually secret and only revealed afterwards.
Is the snapshot the same as the claim date?
No. The snapshot decides eligibility. The claim opens later, usually at or after the TGE.
