Airdrop farms on Ethereum and BNB Chain use a wallet once and move on

Airdrop hunters have a favorite suspect: the address that claims every drop. We followed 2026's farm wallets past their first claim to see whether they fit the picture.

At a glance
About two million wallets claimed 2026's 51 biggest EVM airdrops. The usual picture of a farmer is one wallet that claims everything. On Ethereum and BNB Chain the data shows the opposite. Wallets we can link into farm groups almost never claimed a second drop: 3% on Ethereum and 7% on BNB Chain, against about a quarter of other claimers. Most farm wallets were new, first funded within a month of the claim. The addresses that come back drop after drop are mostly not in any farm group. Base is the exception.

01 · One farm15 out of 33,649

The ROBO airdrop on Ethereum in February was one of 2026's most heavily farmed. In our ROBO investigation we traced one group through thousands of claim wallets, each funded through a chain of throwaway hops, that took most of the airdrop.

We checked what those wallets did next. Of the 33,649 ROBO claimers that sit in farm groups, just 15 turned up in any other big airdrop this year. Among everyone else who claimed ROBO, more than one in four did.

Almost none of the farm wallets turned up in another big airdrop.

That is the pattern across the year's biggest drops on Ethereum and BNB Chain. Farms build a wallet for one drop and leave it behind.

02 · FarmingWhat an airdrop farm is

An airdrop rewards early users with free tokens. A farm tries to collect many shares of it by running thousands of accounts that each pose as a separate user, a trick known as a sybil attack.

We link claim wallets into groups in three ways. They were funded from the same source in one burst, sent their tokens to the same exchange deposit address, or sent them to the same collecting address. A connected group of ten or more is a farm. The last two links are the strongest evidence: a deposit address belongs to one exchange account, and a collecting address usually has one owner.

03 · One drop eachFarm wallets rarely come back

On Ethereum, only 3% of farm-linked claimers took part in two or more of the year's big drops. Among everyone else it was 27%. On BNB Chain the gap was 7% against 25%. Using only the strongest links, the gap barely moves.

On Ethereum and BNB Chain, farm wallets almost never came back; on Base they did.

The common picture has it backwards. An address that shows up in many airdrops is more likely to be an ordinary user than a farm. The farm wallet claims once, passes the tokens on and is not seen in another drop.

04 · Fresh walletsMade for the claim

The reason is in how farm wallets start. On Ethereum, 80% of them got their first funding within a month before the claim, against 45% of everyone else. On BNB Chain it was 84% against 56%.

Farm wallets were far newer than other claimers, and on Ethereum the serial claimers were the oldest of all.

A fresh wallet has no history that ties it to the rest of the farm, and it costs little to make. Once it has taken its share and passed the tokens on, it has done its job.

05 · Serial claimersWho comes back drop after drop

About 270,000 addresses collected from two or more of the big drops, 141,155 from three or more and 26,664 from six or more. One collected from 18.

Tens of thousands of addresses joined several drops, and few of them sit in farm groups.

Few of those in six or more drops sit in farm groups, between 3% and 7% depending on the chain. On Ethereum they are also old: only 3% of the six-or-more group were new when they first claimed there, though on BNB Chain about half were. Nor are repeat claimers quicker to cash out. In the median drop, 4.2% of repeat claimers sent tokens to an exchange within a day, against 5.6% of one-time users.

06 · BaseThe exception

Base does not follow the pattern. There, farm-linked claimers came back about as often as everyone else, 14% against 15%, and those tied by the strongest links came back more. Farms on Base appear to reuse wallets across drops.

Farms were also a smaller part of the crowd there. About one in fourteen Base claimers sat in a farm group, against more than a third on Ethereum.

07 · What it meansFilters aimed at the wrong people

A common assumption is that addresses which claim many airdrops are farms, and some eligibility filters penalize them. On Ethereum and BNB Chain in 2026, that test points at the wrong people. The farms we can see used new wallets, funded in bursts and emptied into shared addresses, and most of them never showed up again.

For projects, the useful signals are the ones farms find hard to hide: many new wallets funded from one source on the same day, and many claimers sending to the same deposit address. The deposit-address trail is how we followed edgeX's unlocked airdrop whales to its own exchange. For regular users who join many airdrops, the data is on their side.

08 · The answerHow we checked, and what it means

We used Bitquery's archive of token transfers for the 51 drops in our 2026 airdrop scorecard, with exchange addresses from our address labels. The same address counts as the same user on every EVM chain, and a token's claim rounds count once. A wallet's age is the time of the first funding we see, compared with its first claim on that chain. Anyone can follow a claimer's funding and exits with the Bitquery MCP.

So do airdrop farms farm every drop? On Ethereum and BNB Chain, their wallets do not. Almost every one claims once, from a new address, and disappears. The addresses that keep coming back are mostly people.

FAQ

Do airdrop farmers reuse the same wallets?

Mostly not, on Ethereum and BNB Chain. Very few farm-linked claimers there took part in a second big airdrop in 2026, far fewer than other claimers.

Are wallets that claim many airdrops sybil farms?

Usually not. Only a small share of the addresses that joined six or more of 2026's big drops sit in farm groups.

How can a project spot an airdrop farm?

Look for many new wallets funded from the same source on the same day, and for many claimers sending tokens to the same exchange deposit address.

Is Base different?

Yes. On Base, farm-linked claimers came back for repeat drops about as often as everyone else.
