Airdrops 101 (2026): How They Work, How to Earn, How Not to Get Filtered
An airdrop is marketing budget paid to early users — tokens distributed retroactively for having used a product. ARB, HYPE, and JUP each paid many users the equivalent of thousands of dollars per wallet.
| Item | Detail |
|---|---|
| Upfront cost | $0+ (depends on type) |
| Requirement | A self-custodial wallet (you hold the keys) |
| Expected value | Case-by-case; $100s–$10,000s precedents |
| Biggest risk | Phishing sites and seed-phrase theft |
Why free money exists
- Decentralization: concentrated ownership is a regulatory and market liability
- Marketing: rewarding real users beats buying ads
- Culture: since Optimism, "use and be rewarded" became the industry norm
The giver has rational motives — this is earned compensation, not a scam-flavored lottery.
The four farm types
| Type | Example | Cost | Effort |
|---|---|---|---|
| Passive | Grass | $0 | ~zero |
| Spending | Tria, KAST | living costs | ~zero |
| Trading | Hyperliquid, Jupiter | trading capital | medium |
| Testnet | new L2s | gas | high |
Beginners: start with the top two — zero capital risk while you learn.
The principles that get paid
Before the announcement, organically, consistently.
- Snapshots are taken unannounced — reacting to news is too late
- Scoring follows duration × frequency × value (the ARB template)
- Building a daily-driver habit (aggregator, wallet) is the strongest organic signal
My base setup: spending-type as the foundation, one or two trading farms deep. Wide-and-shallow loses everywhere.
What gets you excluded
- Funding multiple wallets from one source — sybil clustering wiped thousands of wallets in ARB
- Clicking DM''d claim links — claims happen on official sites only
- Entering your seed phrase anywhere — that''s handing over your funds
Bottom line
One first step: create a wallet and register for one spending or passive farm. Our projects list tracks live programs with expected-value ratings.

Primary sources
The explanation of how eligibility gets decided is drawn from criteria that were actually published. If you want the originals:
- $ARB airdrop eligibility and distribution specifications (Arbitrum DAO) — the duration × frequency × value scoring, and the sybil deductions
- Airdrop #1 eligibility criteria (Optimism Collective) — an example where contributions that cost nothing, such as DAO voting and Gitcoin donations, counted
- Initiating Genesis Drop (Celestia) — the pattern of paying the users of a neighbouring ecosystem
