Unpacking DeFi Summer: The 7 Key Liquidity Pools That Triggered a Financial Revolution

The world of Decentralized Finance (DeFi) saw a major boom in the summer of 2020, often called the 'DeFi Summer.' This period was marked by a rapid increase in total value locked (TVL) within DeFi platforms, and a major driving force behind this surge was the rise of liquidity pools. These decentralized marketplaces or exchanges enable users to lend, borrow, and trade cryptocurrencies in a permissionless manner. Liquidity pools have become the foundation of the DeFi ecosystem, making token exchanges smoother, providing liquidity, and rewarding users for their participation as liquidity providers. Below, we'll explore how liquidity pools contributed to the DeFi summer explosion.

1. Uniswap: The Game Changer

Uniswap, an Ethereum-based decentralized exchange, revolutionized the space with its automated market maker (AMM) model during the DeFi summer. Uniswap allowed anyone to become a liquidity provider by depositing pairs of tokens into a pool. In return, liquidity providers earned trading fees based on their contribution to the pool. This innovative approach, combined with lucrative rewards, brought in a massive amount of liquidity and played a crucial role in the DeFi surge.
