Crypto Airdrops of the Week: All Week 39 Claim Deadlines

Crypto Airdrops in Week 39: The Deadlines Running Now

This week holds one date that is final, and it is four days away. Anyone holding Beldex or Humanity at the crypto exchange Kraken was credited the respective replacement token automatically by airdrop. It can only be withdrawn until September 25, 2026 at 14:00 UTC. After that the exchange liquidates the remainder itself, and it states in its own notice that the proceeds may come to little or nothing.

A second closing date falls into this week as well, one that was missing from this list until now and is harder than any exchange deadline. Sonic burns roughly 32.69 million unclaimed S tokens from Season 1 and Season 2 on October 15, 2026. The tokens are destroyed on chain rather than merely withheld, and in such a way that afterwards any address at all can trigger the burn. Anyone sitting on an old Sonic allocation has a good three weeks left.

This overview lists the airdrops for which a claim window is open this week or a date is fixed. Every figure comes from the source linked at that point, retrieved on September 21, 2026. Where a project has published no end date, that is said explicitly; estimated deadlines have no place here. Last week’s status is in our piece on the week 38 airdrops.

The Deadlines at a Glance

1. Beldex and Humanity at Kraken: Four Days Until the Airdrop Expires

This entry is the most urgent on the list and at the same time the most unusual, because nobody had to claim anything here. Both projects were attacked in June 2026, both rolled out a new token contract in response and distributed the replacement one for one to holders as of the snapshot. Kraken handled the distribution for its customers and credited it automatically. An airdrop that nobody had to claim can expire all the same.

The key data differ by project, which is why there are two separate notices. For Humanity the snapshot was taken on June 8, 2026 at 17:25 UTC, set by the project team itself; the new $HUMANITY was credited on July 1, 2026 at 14:00 UTC. For Beldex the snapshot was taken on June 10, 2026, and the new $BELDEX was credited on July 10, 2026 at 14:00 UTC. Anyone who bought the respective token only after the snapshot has no entitlement according to the exchange; for Beldex it explicitly names neither an application portal nor any other route.

Kraken lists four affected tickers rather than two: the old $H and $BDX and the new $HUMANITY and $BELDEX. Trading and deposits are switched off permanently, and only withdrawals are still supported. Withdrawals close on September 25, 2026 at 14:00 UTC. Whatever is still in the account after that goes into a liquidation phase running from September 28 to October 2, 2026. The exchange writes itself that the proceeds could fall well below the reference prices last seen and, depending on liquidity, may be minimal or zero.

Anyone who held both tokens has two separate jobs to do. The details are in the exchange’s notices on Humanity (H) and on the Beldex migration. We wrote up the background to the Humanity case in more detail in our piece on the Kraken deadline for $H.

2. Sonic (S): 32.69 Million Tokens Will Be Burned on October 15

This is the new addition of the week, and it belongs here because it has something that is rare in this field: a hard end date, published for months, with a clear consequence. Sonic Labs announced on April 2, 2026 that all unclaimed airdrop shares from Season 1 and Season 2 would be released for burning after October 15, 2026. According to the project, around 32,690,000 S are affected.

The mechanism is remarkable and it is the reason why no renegotiation is possible here: once the deadline has passed, the contract allows any address at all to trigger the burn. No decision by the team is needed any more, and no announcement of a date. The date is October 15, and after that it can happen at any time. Anyone hoping for a quiet extension of the kind common at many claim portals is hoping for something the contract does not provide for.

Important for context: since April 18, 2026 the claim has been possible without a penalty, before that it came with a reduction. Anyone who waited out of fear of the penalty has been waiting for no reason for months. The claim runs through the project’s portal at my.soniclabs.com/airdrop, and for positions held as fNFTs additionally through the marketplace set up for that purpose. The announcement with all the details is in the Sonic Labs blog.

A word on expectations: the fact that so many tokens are still unclaimed after a year and a half is the rule rather than an oversight by users. A substantial share of every allocation is never collected, because the wallet was forgotten, the amount was small or the announcement went unnoticed. If you were active on Sonic in 2024 or 2025, the look into the portal is due now, in September rather than in October.

3. Grass (Stage 2): The Only Window With a Clean Closing Date

Grass has been distributing its Stage 2 rewards since July 22, 2026 and has given the claim a six-month window: until January 22, 2027. Whatever has not been claimed by then expires according to the project and stays with it. That makes Grass the counterpart to the three entries further down, with an end date that stood there from the start.

Eligible are wallets that contributed bandwidth between October 14, 2024 and June 8, 2026 (epochs 1 to 19) and linked a Solana wallet as part of Stage 2. The allocation is visible after signing in to the dashboard; a separate application is not required. Two of the six months have now passed, leaving four.

The only legitimate place to check and claim is the dashboard at app.grass.io. The project points out explicitly that it never contacts anyone of its own accord and never asks for a seed phrase or a private key. Those are exactly the patterns at work around every larger airdrop.

4. GRVT: 30 Days per Tranche, and the Calendar Sits Only in Your Account

The derivatives exchange GRVT held its token generation event on July 30, 2026 and is distributing 280 million GRVT in total. The distribution runs in tranches over twelve months, and each unlocked tranche carries a claim window of 30 days. Once it expires, the tranche is permanently lost according to the project, and it does not roll into the next one.

This is the most awkward entry on the list, because there is no published unlock schedule. When the help page was retrieved again this week, it still carried no date for the next tranche. For allocation and timing the project refers exclusively to the reward portal of your own account. The calendar is therefore individual, and there is no public place where you could look it up.

There is also a distinction that is easily missed: only the first tranche due is paid out automatically, and only for registrations made before July 17, 2026. Anyone who signed up later has to claim every tranche themselves according to the wording of the help page, within 30 days in each case. Practical advice: take one look at the reward portal, enter the end date given there in your calendar, with a reminder a few days ahead.

5. Plume and dappOS: Open, but Without a Published End

Two entries carry over unchanged from previous weeks, and both share the same problem. At Plume (Season 2) the points programme ended on March 31, 2026 and registration ran until May 27, 2026; anyone who missed it is excluded, and that cannot be made up. The claim has been running through the official portal since the end of May, and Plume has at no point named an end date. Secondary reports circulate a period of roughly three months that would have run out at the end of August. That figure does not come from the project, and we carry it here only because it circulates, explicitly not as a deadline.

At dappOS, phase 2 has been running since August 11, 2026, in which eligible wallets can claim transferable DOS. Here too the project has published no end for any of the phases so far. The only correct route is the claim portal on the project domain.

The conclusion is the same for both and it matters more than any assessment of token value: 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. Anyone eligible should claim instead of waiting.

Not Included, and Why

This section is the more important part of the research. The following candidates were checked this week and deliberately left out:

• LAPTOP (Hunter Biden’s memecoin) at Bitvavo: the deadline cannot be evidenced at the source. For customers with losses of more than 1,000 euros in the TRUMP token, a registration deadline of October 10, 2026, 23:59 CEST is circulating. We cannot get it confirmed: the project page names only a claim window of “30 days” without a calendar date, the project’s claim portal shows neither start nor end, and the exchange’s own pages could not be read when retrieved on September 21, 2026 (HTTP 403). Thirty days from a date that has not been published do not add up to an end date, and we do not calculate one here. Two things should be said anyway, in case you see an invitation in your account: under its own terms the campaign is a promotional reward programme and explicitly not compensation, reimbursement or redress for TRUMP losses, and a memecoin stays a memecoin even when it is distributed through a regulated exchange.
• Fireplace: a wind-down, not an airdrop. September 30, 2026 is a real and important deadline, but it is the cut-off by which users of the discontinued Polymarket trading terminal have to withdraw their balances and migrate open positions. A platform wind-down is not a token distribution.
• XDAO ($DAO): deadline passed, never confirmed at the source. The snapshot cut-off circulating for September 20, 2026 at 14:00 UTC appeared exclusively on aggregator sites; the project page and the documentation mentioned neither a snapshot nor a TGE. The date has now passed and a TGE date is still unpublished. Last week’s decision to leave it out was right and stands.
• Meteora (MET): from last year. Unchanged: the widely shared announcement of “September 10” dates from September 10, 2025, and the TGE took place on October 23, 2025.
• AVANT: TGE without a date. The token generation event was last targeted “for September”, and the claim is meant to open “around the TGE”. A period is not a date.
• Arcium (ARX): open, but without a deadline. The retroactive token grants continue in rolling waves, without any point by which the claim has to be made.
• Canopy (CNPY), RISEx, mint.io (MNTD), Ink (INK), OpenSea (SEA): points programmes or TGE without a date. At OpenSea the launch originally expected for the end of March 2026 has been postponed without a replacement date being named.
• ARC (Circle): a mainnet launch is no airdrop. The public launch on September 16, 2026 carries neither a TGE date nor a confirmed community allocation.
• Exchange dates with no airdrop link. Trading closures and delisting deadlines are real, yet they remain something other than airdrops, with the exception of the Kraken case above, where the token to be withdrawn itself comes from a distribution.

On top of that comes 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 no deadline.

What to Watch Out for With Every Claim

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

• Check the year first. For several weeks running this column carried a prominently traded “current” airdrop that in truth 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 serious airdrop asks for your seed phrase or your private key.
• Check which permission you are granting before you sign. An unlimited token approval is never needed for a claim.
• Weigh the network fee against the value of the allocation. With very small amounts the claim can cost more than it brings in.
• Put every deadline in your calendar, and with staggered distributions such as GRVT’s, every single tranche rather than only the first.
• And the point that carries this week too: a published end date is the only thing that makes the closure of a claim predictable. Without one, that closure never has to be announced at all.

And Afterwards? The Token Sits in the Wallet

The question that comes after every successful claim is a practical one: what do you do with an allocation that is not listed on any large exchange? Most freshly distributed tokens are low-cap assets with a thin order book, and that is exactly where the gap between looking and acting is widest. Tools such as Dexscreener or TradingView show you prices and liquidity, but you cannot execute anything there. An app like FOMO Family takes the other route: meme and low-cap tokens can be discovered, swiped through and traded directly in the app, with fast deposits. Download the app through the link and secure yourself ten percent off trading fees. The necessary warning belongs right next to it: trading meme and low-cap tokens is highly risky, volatility is extreme, and a total loss is possible at any time. Do not put anything in here whose loss would hurt you.

If you want to read into the subject instead of just working through deadlines: how airdrops work, who is typically eligible and how dubious campaigns can be recognised is covered in our guide to crypto airdrops.

Think About Tax Straight Away

An airdrop is not a tax-free gift by definition. Whether the allocation has to be treated as other income under section 22 number 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. Two cases from this week show why that is more than theory. In the Kraken case the inflow of the replacement token in July and the later withdrawal or sale have to be kept apart, and a forced liquidation by the exchange is a transaction you have to document even though you did not trigger it. In the Sonic case the question runs the other way: a burn of unclaimed tokens is neither a sale nor a loss you could claim.

So secure the time, amount, market value, price source, transaction hash and the terms of participation right at the moment of the claim. Experience shows the terms are the first thing to disappear when a campaign page is switched off. Which details count individually is set out in our guide “Receiving airdrops: save this data immediately”. That unsold tokens can trigger a tax liability as well is explained under “Unsold airdrops: tax liability even without a sale”.

Conclusion

Week 39 carries two tasks and three observation posts. The first task is September 25, 14:00 UTC: anyone who held Beldex or Humanity at Kraken has had the replacement token in the account for a long time and four days to withdraw it, twice over where both tokens are affected. After that the exchange decides on the liquidation, and it says itself that the proceeds may come to little or nothing.

The second task is October 15 and it concerns considerably more people than are aware of it: 32.69 million unclaimed Sonic tokens will be released for burning after that date, triggerable by anyone. This is no portal you can still reach later if it comes to it. A look into the Sonic portal costs five minutes and is the most worthwhile action of the week if you were active there in 2024 or 2025.

The remaining entries are for observation: Grass with the only clean closing date on January 22, 2027, GRVT with a 30-day window per tranche whose calendar sits only in your own account, plus Plume and dappOS with open windows and no published end.

The methodological finding of the week sits in the section above. The most prominent new deadline of this week, the LAPTOP campaign through a large European exchange, did not make the list because the date could not be evidenced at any project or exchange source. A date that appears only in reports about the date is no documented date. And the necessary sobering note stands: most allocations move in the double to low triple digits, and the fee for claiming eats a noticeable part of that. The effort pays off above all where you are already eligible anyway.
