Launched in 2018, Uniswap is a decentralized exchange protocol that allows users to swap between any two ETH-based tokens. Apart from providing a simple platform to liquidity providers, Uniswap has made the whole process of providing liquidity and earning trading fees a lot simpler.
Uniswap liquidity providers earn trading fees on every trade made on Uniswap. In return, the liquidity providers facilitate trading between different ETH-based tokens, which will improve the trade volume and the popularity of the platform.
On September 17th, 2020 Uniswap launched its UNI token with a massive airdrop that distributed 400 UNI to all the users who used their protocol in the past. In total, 15% of UNI total supply was distributed through the airdrop.
Following the same pattern, Impermax Finance, a DeFi lending protocol, airdropped 14 Million IMX tokens to 35,000 Uniswap V2 Liquidity Providers on April 29. Each one of the 35,000 received 400 IMX, an amount inspired by the notorious UNI airdrop.
