The most urgent airdrop deadline this week: GRVT's first tranche expires at the end of August. Propr launches August 24. Plume and dappOS lack published deadlines. Grass has until January 2027.
GRVT's first airdrop tranche expires at the end of August. The derivatives exchange held its token generation event on July 30, 2026. The first tranche of Season 1 tokens carries a claim window of 30 days. After that, unclaimed tokens are forfeited. The project's help section says exceptions are not possible.
Anyone who registered before July 17 and set a destination chain received the first tranche automatically. Everyone else must claim manually through the reward portal. Registration closed on July 27 at 00:00 UTC. Only those already eligible can still act. The expiry date follows from the rule published on July 30. The project has not issued a separate countdown. Checking the portal and claiming immediately is the safest course.
A total of 280 million GRVT is being distributed, 100 million from Season 1 and 180 million from Season 2. The distribution runs in tranches over twelve months. Each unlocked tranche has its own 30-day window. The first is about to close.
The only hard start date inside the 14-day window is Propr, an on-chain prop trading platform on Hyperliquid. The tokenomics proposal dates the token generation event to August 24, 2026. The phrasing leaves room for change. The plan allocates 20 percent of the fixed one-billion PROPR supply to a genesis airdrop that unlocks in full at launch. Points were earned by buying trading challenges. One dollar spent counted as ten points regardless of outcome. The project has not yet published the specific claim mechanics or any deadline for the claim. All investor rounds, the airdrop, and the liquidity unlock simultaneously at launch. That creates considerable selling pressure on the first trading day.
Plume's Season 2 airdrop claim has been running since the end of May 2026. Registration closed on May 27. Only those already enrolled can participate. The condition was at least 10,000 Plume Points collected by March 31, 2026. Plume itself gives no end date for the claim window. It only says it starts 'later in May.' Industry reports mention a window of around three months. That would run out sometime in August. That figure is not from the project. A risk of expiry without notice exists. Claiming immediately costs only the network fee.
dappOS launched its token on August 10, 2026. Phase 1 and phase 2 claims are open. No end date has been published for either. Phase 3 has been announced without a date. The listing schedule is clear: MEXC and Bitget listed on August 10. KuCoin and Biconomy listed on August 11. The project advises checking only its own channels for deadlines. The lack of a published expiry means the safest course is to claim early through the portal at dappos.com.
Grass offers the most relaxed deadline. Stage 2 rewards are claimable through January 22, 2027. The dashboard is at app.grass.io. Unclaimed amounts are retained by the project. The eligibility period covers epoch 1 through epoch 19. That is the period from October 14, 2024 to June 8, 2026. Payment is in USDC, not GRASS tokens.
An airdrop does not automatically qualify as tax-free. Whether the allocation is taxable as other income depends on whether the recipient provided something in return. Anyone who collected points through purchased trading challenges or through trading volume stands differently from someone who received an allocation without consideration. The terms of participation and the transaction hashes should be recorded immediately. Campaign pages often disappear.
Across the five airdrops, four lack a clear published expiration date. The exception is GRVT, where the rule is hard and the window is closing. Most allocations run in the two- to three-figure range. A significant portion of all airdropped tokens are never claimed at all.
