The Most Profitable Crypto Airdrops of the Week: Week 38

Updated on September 18, 2026: the Kraken deadline now stands at seven days. All five sources were checked again on that day and carry unchanged deadlines. Two statements have been corrected: for Humanity there is, contrary to our original wording, an application portal run by the project team, and barely two of the six months of the Grass claim have elapsed, not four. Newly added to the exclusion list: XDAO.

Crypto airdrops in week 38: these claim windows are running now

This week holds only one date that really bites, and it is now seven days away. Anyone who held Beldex or Humanity at the crypto exchange Kraken has already been credited with the respective replacement token by airdrop. The only thing left to do with it is to withdraw it, and that option closes on September 25, 2026 at 14:00 UTC. After that the exchange liquidates whatever is left. This is the last full calendar week before that date, and there are two separate notices for two separate tokens: anyone who held both has two things to do.

As in the previous week, a warning belongs at the top, because the pattern has repeated itself. Last week it was Holoworld AI, whose claim from September 2025 was circulating through search results as a fresh airdrop. This week it is Meteora (MET). The project confirmed its TGE and airdrop in an announcement dated September 10, from September 10, 2025. The TGE took place on October 23, 2025. Two weeks, two prominent “live” airdrops that actually date from the previous year. That is no coincidence. It is the basic pattern of this field: airdrop announcements display the day and the month prominently and the year almost never. Check it first.

This overview lists the airdrops that either have a claim window open this week or have a confirmed date within the next 14 days. Every figure comes from the source linked alongside it, retrieved again on September 18, 2026. Where a project has published no end date, that is stated explicitly. There are no estimated deadlines here. For the state of play a week ago, see our piece on the airdrops of week 37.

The dates at a glance

1. Beldex and Humanity: seven days until forfeiture

This entry is the most unusual on the list, because nobody here had to claim anything. Both projects were attacked in June 2026, both responded by rolling out a new token contract and distributing the replacement one for one to holders as of the snapshot. Kraken handled the distribution for its customers and credited it automatically, which is why two additional lines have been sitting in those accounts ever since. An airdrop you never had to claim can still expire.

The key data differ by project, and that is the reason for the two separate notices. For Beldex, the snapshot was taken on June 10, 2026 at 23:36 UTC, and the new token was credited on July 10, 2026 at 14:00 UTC. For Humanity, the snapshot came earlier, on June 8, 2026 at 17:25 UTC, set by the Humanity team itself, and the new $HUMANITY was credited as early as July 1, 2026 at 14:00 UTC. Anyone who bought the token in question only after the snapshot is not entitled to it according to the exchange. On this point, however, the two cases differ, and we initially presented them as identical: for Beldex the exchange explicitly names no application portal and no other route. For Humanity it points to an application portal run by the Humanity team, through which those affected can submit a claim directly; the exchange itself is not involved in that process and does not answer questions about it.

The ending, by contrast, is identical for both. Trading and deposits have already been switched off for all affected tickers, withdrawal remains the only function, and it closes on September 25, 2026 at 14:00 UTC. From September 28 to October 2, 2026, the exchange will liquidate any remaining balances itself. In the same notice it points out explicitly that the proceeds may fall well below recently seen prices and, in individual cases, may be minimal or zero. When the notices were retrieved again on September 18, 2026, neither carried any reference to an extension.

What has to be done this week therefore comes down to a single action with a date attached: withdraw before the window closes, and do it separately for each of the two tokens. We have written up the full procedure, including the contract addresses that distinguish the old token from the new one, under “Kraken withdrawal deadline on September 25”. The separate route for Humanity and the unlocking of the token are covered under “Humanity unlock: the H deadline at Kraken”.

2. Plume (Season 2): claim open, end date still unpublished

Plume is a layer 1 chain for tokenised real-world assets. Season 2 of the points programme ended on March 31, 2026, and registration for the distribution ran from April 29 to May 27, 2026. Anyone who missed that step is excluded according to the project, and there is no way to fix it retroactively. Eligibility required wallets with at least 10,000 Plume Points, in some cases plus verification through Human Passport.

The claim has been running through the official portal since the end of May 2026, and the gap of recent weeks remains unchanged: Plume has at no point named an end date. The announcement text gives the registration deadline and says of the claim itself only that it is planned for “later in May”, with the exact date to follow through the official channels. To this day it has not followed. On September 18, 2026, the most recent blog post was still the one dated September 10, 2026; none has been added since the last check, and none of the three posts of September 8, 9 and 10 concerns the airdrop.

The figure circulating in secondary reports, a window of roughly three months that would arithmetically have run out at the end of August, still does not come from Plume. We carry it only because it is circulating, and explicitly not as a deadline. In practice that changes nothing about the advice. If anything it sharpens it: a claim with no published end date can be closed at any time without prior announcement. Anyone eligible and registered should claim rather than wait.

Source: Plume, “Plume Points Season 2 Airdrop Registration Is Now Open” (retrieved again on September 18, 2026; the announcement still names no end date for the claim, and the project blog carries no post on the subject)

3. Grass (Stage 2): deadline of January 22, 2027

The Solana project Grass has been paying out its Stage 2 rewards since July 22, 2026. Epochs 1 to 19 are covered, meaning the period from October 14, 2024 to June 8, 2026. The claim runs through the project's official dashboard.

Grass is one of the few projects with a cleanly published deadline. The claim is open until January 22, 2027, a full six months. Whatever has not been claimed by then stays with Grass. That is the literal wording in the project documentation, and it was still there unchanged when the page was retrieved again on September 18, 2026. This is the most comfortable entry on the list and, experience suggests, still the one where most value is left on the table, because half a year feels like unlimited time. Four of the six months have now passed. Put the date in your calendar if you are eligible.

Source: Grass, “How Your Stage 2 Rewards Allocation Works” (retrieved again on September 18, 2026; the January 22, 2027 deadline and the forfeiture clause carry unchanged wording)

4. GRVT: every tranche runs its own 30-day clock

The derivatives exchange GRVT held its token generation event on July 30, 2026 and is distributing a total of 280 million GRVT. The mechanics are the strictest on this list. The distribution runs in tranches over twelve months, and every unlocked tranche carries a claim window of 30 days. Once it expires, the tranche is permanently lost according to the project.

Two points are decisive here and are regularly confused. First, registration: it closed on July 27, 2026 at 00:00 UTC, and anyone who missed it has forfeited their allocation, which no later claim can undo. Second, automation: only the first tranche that falls due is sent automatically, and even that only where registration happened before July 17, 2026. Anyone who signed up later has to claim every tranche themselves through the Reward Portal, according to the wording of the help text, and to do so within the 30 days.

GRVT publishes no unlock schedule, and when the help section was retrieved again on September 18, 2026 it carried no date for the second tranche. For allocation and vesting schedule the text refers exclusively to the Reward Portal of your own account. We deliberately do not calculate the date here. What counts is the expiry date the portal displays for your specific tranche. This is precisely where forfeited entitlements arise, so set yourself a reminder. The project recommends as much itself.

5. dappOS (DOS): phase 2 open, phase 3 still without a date

The DOS token launched with its TGE on August 10, 2026, and phase 2 has been running since August 11, 2026, in which eligible wallets can claim transferable DOS. A phase 3 has been announced, but without a date, and no end date has been published for any of the phases so far. Nothing has changed there since last week. The claim portal on the project domain is the only official route.

What comes afterwards is the real decision. A freshly distributed token with a small market capitalisation swings wildly in its first weeks, and the selling pressure from an ongoing claim hits it on top of that. Anyone who wants to trade such a position at all needs access that covers the small pairs. Pure charting tools such as Dexscreener or TradingView only display prices; no trading happens there. One alternative is the mobile app FOMO Family, which lets you discover, swipe through and trade meme and low-cap tokens directly in the app, with fast deposits. Download the app through the link and secure yourself a 10 percent discount on trading fees. Sobriety belongs with that: trading meme and low-cap tokens is highly risky, volatility is extreme and a total loss is possible at any time. Where else DOS is traded can be seen in our comparison of crypto exchanges.

What has changed since last week

• The Kraken deadline has moved into close range. The withdrawal window closes on September 25, 2026 at 14:00 UTC, seven days from this update. Newly documented in this edition are the separate key dates for Humanity: snapshot on June 8, 2026 at 17:25 UTC, credit on July 1, 2026 at 14:00 UTC, both earlier than for Beldex.
• Plume, Grass, GRVT and dappOS unchanged. All four sources were retrieved again on September 18, 2026, and none carries a new or amended deadline. Plume has added no further blog post since the last check.
• A new case for the year check: Meteora (MET). It replaces Holoworld AI as the example of the week, and there is more on it in the next section.

What is deliberately missing this week

These candidates did not make the list. The reason differs in each case, and each reason is worth as much as an entry:

• Meteora (MET), wrong year, and the second week in a row for this pattern. The report “Meteora confirms TGE and airdrop” is circulating prominently at the moment and carries the announcement date of September 10. The year, however, is 2025, the TGE took place on October 23, 2025, and the allocation checker went online on October 16, 2025. There is nothing left to collect here.
• AVANT, a period instead of a date, and now past its own time frame. As of September 18, 2026, the project documentation lists the TGE as “Tentatively September” and the token claim as “Expected around TGE”, with the final date to be announced through the official channels, and that the claim is to open “around TGE”. It names no deadline. The previously communicated “mid-September” has thus been reached without a calendar day on the table. As soon as a day is named, the entry follows.
• Midnight (NIGHT), source unverifiable for the fourth week running. The key data carried so far, thawing until December 4, 2026 followed by a 90-day grace period, come from a check in mid-August. Since then neither the project blog nor the developer documentation could be checked again. There is no indication of a change, but we can no longer document the deadline, and an undocumented deadline does not belong in the table in this format. Anyone who depends on it should call up the project page themselves.
• Ink (INK), a time window, not a deadline. A period rather than a date continues to circulate for the Kraken layer 2. Collecting points is not a claim date.
• Arcium (ARX), open, but without a deadline. The retroactive token grants have been running in rolling waves since the Solana launch in June 2026. Neither the project site nor the documentation names a point by which a claim has to be made. Not to be confused with an exchange's Airdrop+ programme, which ran from June 22 to July 6, 2026 and finished long ago: that was a trading promotion, not a project airdrop.
• Canopy (CNPY), RISEx and mint.io (MNTD), points programmes without a TGE date. Unchanged from last week; none of these candidates has published a date since.
• ARC (Circle), a mainnet launch is not an airdrop. The public mainnet launch on September 16, 2026 falls in this week and is therefore frequently listed among airdrops. A TGE has no date and a community or airdrop allocation is not confirmed. Without both, it does not belong here.
• XDAO ($DAO), a deadline that exists only at aggregators, not at the project. A snapshot cut-off of September 20, 2026 at 14:00 UTC is circulating, by which a Solana wallet is said to have to be linked. That would be a date within 72 hours and therefore a case for this list, but it appears exclusively on aggregator sites. As of September 18, 2026, neither the project site nor the project documentation mentioned an airdrop, a snapshot or a TGE. Without evidence at the project source we do not take it in, precisely because short deadlines are the lever of every counterfeit claim page.
• Exchange dates with no airdrop connection. The end of trading for 21 Kraken tokens and comparable deadlines are real, but they are not airdrops. They appear in our pieces on exchange dates and do not belong on this list.

Alongside that, the standing rule of this format: projects listed as “live” on aggregator sites but naming neither a snapshot nor a claim window at the project source do not get in. “Airdrop confirmed, date open” is not a deadline.

What to watch on every claim

Airdrops are the preferred hunting ground for wallet drainers, and the patterns repeat:

• Check the year first. For two weeks running, a prominently traded “current” airdrop stood here that actually dated from the previous year, and an expired claim is the perfect template for a cloned scam page.
• Always open the claim page through the official project domain, never through links in direct messages, comments or search ads.
• No legitimate airdrop asks for your seed phrase or your private key.
• Check which permission you are granting before you sign. An unlimited token approval is not necessary for a claim.
• Weigh the network fee against the value of the allocation. For very small amounts, claiming can cost more than it returns.
• Put every deadline in your calendar, and with staggered distributions such as GRVT's, put in every single tranche rather than only the first.
• And the point that carries this week too: a claim without a published end date is not a claim with unlimited time. It is one whose closure does not have to be announced.

Think about the tax position straight away

An airdrop is not by definition a tax-free gift. Whether the allocation has to be treated as other income under Section 22 No. 3 of the German Income Tax Act depends above all on whether you provided something in return, which is also how the still authoritative circular of the German Federal Ministry of Finance of March 6, 2025 draws the line. This week's Kraken case also shows that two events have to be kept apart: the inflow of the replacement token in July, and the later withdrawal or sale. A forced liquidation by the exchange is likewise an event you have to document, even if you did not trigger it.

So when you claim, record the time, the quantity, the market value, the price source, the transaction hash and the terms of participation straight away. The last of these tends to disappear first once a campaign page is taken down. That a token you have not sold can also trigger a tax liability is something we explain separately.

The Optimism case shows that a distribution once promised can also be reallocated, which you can read in our piece on the reallocation of the Optimism airdrop. For an overview of further campaigns, see our section on crypto airdrops.

Conclusion

Week 38 is a week with exactly one task and four observation posts. The task is called September 25: anyone who held Beldex or Humanity at Kraken has long had the replacement token in their account and seven days to withdraw it, twice over where both tokens are affected. After that the exchange decides on liquidation, and it says itself that little or nothing may come of it.

The four remaining entries stand unchanged: Plume, GRVT and dappOS with open windows and no published end, and Grass as the only project with a clean closing date of January 22, 2027, of which barely two of the six months have elapsed so far.

The methodological finding of the week is the same as last week's, and that is exactly what makes it matter: once again a prominently traded “live” airdrop turned out to be a year old. When a mistake repeats twice in a row, it is the rule rather than a slip. Check the year before you connect a wallet.

And the necessary sobering note: most allocations run into double or triple digits, the fee for claiming eats a noticeable share of that, and a substantial proportion of all allocated tokens is never claimed at all. The effort pays off above all where you are already eligible.
