Airdrop
Distribution of free tokens to a set of wallet addresses, typically rewarding early users or holders of a related asset.
Airdrops emerged as a marketing tool: rather than ICO/sale, project teams distribute tokens to qualifying wallets, building an instant user base. Uniswap's 2020 UNI airdrop (400 UNI per qualifying address, worth ~$1,200 at the time, $5,000+ at peak) became the template — reward early adopters of the protocol with governance tokens.
Airdrop farming has become a sub-economy. Users perform on-chain activities ("airdrop hunting") — bridging, swapping, providing liquidity, casting NFTs — on protocols expected to launch tokens. The arc from "use protocol" to "claim airdrop" can take 6-18 months and is increasingly gamed by sybil farmers running thousands of wallets.
Tax treatment varies. In the US, airdrops are typically ordinary income at fair market value when received, with separate capital gains on subsequent disposal. In some jurisdictions, claimed airdrops can require active claiming and signing — failing to do so by deadline forfeits the tokens.
Airdrops can deliver life-changing returns ($10K-$100K+ from minimal protocol use) but also fuel speculative on-chain behavior that distorts protocol metrics.

FAQ
Who qualifies for an airdrop?
Criteria vary: some require holding a specific token at a snapshot date; others require past on-chain interactions (using a DEX, bridging tokens, providing liquidity). Project teams publish criteria around launch.
Are airdrops taxed?
In most jurisdictions yes, as ordinary income at FMV when received, plus capital gains on disposal. Consult a tax professional for your country.
What is sybil farming?
Running multiple wallets to qualify for an airdrop multiple times. Project teams use heuristics (transaction patterns, funding sources, timing) to detect and exclude sybil wallets — often controversially.
How do I find legitimate airdrops?
Use the actual protocol over time — bridging, swapping, lending. Avoid "airdrop checker" sites and never sign random transactions: most listed airdrops are scams targeting your wallet.
