The UNI airdrop
Uniswap dropped 400 UNI to every past user. The airdrop-as-distribution playbook was born.
In September 2020, Uniswap launched its UNI token and retroactively gave 400 UNI to every address that had ever used the protocol — worth a few thousand dollars at the time. No sale, no lockup for users: a gift for past usage.
Why it echoed for years
Why it happened when it did
The airdrop wasn't pure generosity — it was defense. Weeks earlier, SushiSwap had forked Uniswap's code and tried to siphon its liquidity with a token of its own: the original "vampire attack." Dropping UNI to real users rewarded loyalty, kick-started governance, and made the case that the moat was the community, not the code. It worked — the liquidity came back.
SushiSwap ── "LP here, earn SUSHI" ──→ pulls Uniswap LPs away Uniswap ── "400 UNI for being early" ──→ LPs (and loyalty) return
It crystallized a new distribution model: reward your users, not just your investors. The airdrop became *the* growth and decentralization playbook — and, inevitably, spawned the airdrop farmer: users who interact with every new protocol speculatively, hoping to qualify for the next drop. A whole behavior pattern traces back to this one event.
