#MajorAirdropWatch Uniswap introduced a new unique concept of airdrops by retroactively distributing their new governance token UNI to early Uniswap users that interacted with the protocol through trading or liquidity provision. Every wallet that interacted with the protocol before the snapshot is able to claim at least 400 UNI. Some users made millions of free money from the Uniswap airdrop. Those so called retroactive airdrops gained traction and several DeFi protocols soon followed. Following Uniswap’s pioneering distribution, retroactive airdrops have evolved to include:

Protocol usage rewards

Early adopter bonuses

Governance participation incentives

Cross-chain activity recognition

Historical engagement rewards
