The Most Profitable Crypto Airdrops of the Week: Week 34

Crypto airdrops in week 34: the deadlines running right now

The most important deadline this week is not one any project is making a noise about. It is one that runs out quietly: at GRVT, every unlocked tranche expires 30 days after it is released, with nothing to replace it. Anyone who has not yet claimed the first tranche from the token launch at the end of July has only a few days left.

This overview lists five airdrops for which a claim window is open this week or a start date within the next 14 days is fixed. Every figure comes from the source linked alongside it. Where a project has published no end date, that is stated explicitly. There are no estimated deadlines here. You will find last week's position in our piece on the airdrops of week 33.

The dates at a glance

Project	Status	Date / deadline
GRVT	claim open, tranche expiring	30 days per tranche, first one since July 30, 2026
Propr (PROPR)	launching	TGE on August 24, 2026
Plume (Season 2)	claim open	no end date published, reports point to August 2026
dappOS (DOS)	claim phase 2 open	since August 11, 2026, end not published
Grass (Stage 2)	claim open	until January 22, 2027

1. GRVT: every tranche expires after 30 days

The derivatives exchange GRVT held its token generation event on July 30, 2026; the allocation checker and the claim opened the same day at 21:00. A total of 280 million GRVT is being distributed, 100 million of it from Season 1 and 180 million from Season 2.

The detail that sets this airdrop apart from most others sits in the project's help section. 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 gone for good. The project puts it without a back door: exceptions are not possible.

Anyone who registered before July 17, 2026 and set a destination chain has the tranche due credited automatically. Everyone else has to claim manually through the reward portal at every single unlock, and that is exactly where the expired entitlements arise. Registration itself has closed; the project gives July 27, 2026, 00:00 UTC as the cut-off.

On the arithmetic, the 30-day rule means the window for the first tranche runs out at the end of August 2026, counted from July 30. GRVT has not published that date as a deadline itself; it follows from the published rule. If you are affected, do not rely on the calculation. Look up the actual expiry date in the reward portal.

2. Propr (PROPR): TGE on August 24

The only hard start date inside the 14-day window comes from Propr, an on-chain prop trading platform on Hyperliquid. The project's tokenomics proposal dates the token generation event to August 24, 2026, phrased as an intention rather than an irrevocably fixed date.

The plan sets a fixed supply of one billion PROPR, of which 20 percent goes to a genesis airdrop that unlocks in full at the TGE. Points for it were collected by buying trading challenges, where one dollar spent counted as ten points, whether or not the challenge was passed. Propr comes from the XBorg team, and a further share is earmarked for stakers of the XBG token.

Two qualifications belong with this, and they are unchanged since last week. First, Propr has still not published the specific claim mechanics or any claim deadline. The TGE date and the split are known, and nothing beyond that. Second, all investor rounds, the airdrop and the liquidity unlock simultaneously at launch, which means considerable selling pressure on the first day of trading.

3. Plume: claim open, end date still unpublished

At Plume this now concerns only those who registered in time. Registration for the Season 2 distribution ran from April 29 to May 27, 2026; anyone who missed it is not part of the distribution, according to the project. The condition was at least 10,000 Plume Points, collected by the March 31, 2026 cut-off.

The claim has been running since the end of May 2026. And here lies the catch we already flagged last week, which has not resolved itself since: in its own announcement Plume gives no end date, neither to the day nor as a period. The blog post says only that the claim starts "later in May". Industry reports speak of a window of around three months, which would run out in August 2026, but that is a third-party figure and not one from the project.

In practice that means this: if the three-month figure is right, one of the last weeks in which claiming is reliably possible is running now. If it is wrong, claiming immediately costs nothing beyond the network fee. The distribution of risk is clear, and it argues against waiting.

4. dappOS (DOS): phase 2 open since August 11

Compared with last week, the position at dappOS has moved on. The token arrived on August 10, 2026 with the TGE and the opening of the claim portal for phase 1; eligibility checking had been possible since August 5. On August 11, 2026, according to consistent exchange and industry reports, phase 2 followed, in which eligible wallets can claim transferable DOS. The same day KuCoin (spot trading DOS/USDT from 12:00 UTC) and Biconomy (from 08:00 UTC) took on the token, after MEXC and Bitget had already listed it on August 10.

A phase 3 has been announced by dappOS, but without a date. And for none of the phases so far has an end date been published. That is not reassurance but the reason to bring the claim forward: a window whose end nobody knows cannot be planned for in time either. The only official route runs through the claim portal at dappos.com, and the project explicitly advises taking dates only from its own channels. Where DOS is traded, you can see in our comparison of crypto exchanges.

5. Grass: stage 2 rewards until January 22, 2027

For completeness, the deadline with the largest buffer, and the most solid number in the entire field. The Solana project Grass has been paying out its stage 2 rewards since July 22, 2026, with the claim running through the dashboard at app.grass.io. The deadline ends on January 22, 2027; amounts left unclaimed are retained by Grass according to its own documentation.

Two details are easy to miss. Payment is not made in GRASS tokens but in USDC. And the eligibility period is tightly drawn: it covers epoch 1 through epoch 19 of stage 2, meaning the period from October 14, 2024 to June 8, 2026. Anyone who collected network points inside that window is eligible in principle.

Still running, with no news this week

At the Cardano-adjacent privacy project Midnight, the thawing phase of the NIGHT token continues unchanged. It ends on December 4, 2026, followed by a grace period of 90 days; payment is made in four equal tranches at intervals of 90 days each. The announced lost-and-found phase for unclaimed NIGHT still has no date. Details are in our piece on the Cardano Midnight airdrop and the NIGHT distribution.

What is deliberately missing this week

Three candidates with plenty of attention did not make the list, and the reason is the same in each case: there is no documented date for a distribution.

• FOLD becomes transferable on August 19, 2026, after a cooldown following the token auction. Transferability is not an airdrop, though, and a distribution to users with its own deadline is not documented.
• RSGP is due to launch in August 2026, but the tokenomics have not been published. Without a distribution date and eligibility conditions, that is not an entry for this format.
• Several projects currently listed as "live" on aggregator sites give neither a snapshot nor a claim window at the project source. "Airdrop confirmed, date open" is not a deadline you can set your calendar by.

What to watch on every claim

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

• Always open the claim page through the official project domain, never through links from direct messages, comments or search ads.
• No reputable 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 needed for a claim.
• Weigh the network fee against the value of the allocation. On very small amounts, claiming can cost more than it returns.
• Put every deadline in your calendar. With staggered distributions such as GRVT's, that means every single tranche, not just the first.

Think about tax 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. With this week's campaigns that is no marginal question: anyone who collected points through purchased trading challenges or through trading volume stands differently from someone who received an allocation without doing anything.

So secure the time, quantity, market value, price source, transaction hash and the terms of participation right at the moment you claim. The last of these tend to disappear first when a campaign page is taken down. Note that unsold tokens can trigger a tax liability as well, which is worth keeping in mind before you decide to simply hold.

An overview of further campaigns is available in our section on crypto airdrops.

Conclusion

Of this week's five dates, exactly one is genuinely urgent: at GRVT the first tranche expires 30 days after July 30, and a missed window is irreversible. Propr launches on August 24 but still leaves the claim details open. Plume and dappOS each lack a published end date, which is no reason to relax but a reason to bring the claim forward. Only Grass leaves real room with January 22, 2027.

And the sobering part: most allocations sit in the two- to three-figure range, 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 mainly where you are already eligible.
