Did you know that thousands of years ago people didn’t use money? They exchanged products or services. For example, you’re a farmer that grows potatoes, and your farmer friend Will grows apples. When you need apples, you can offer him some potatoes in exchange. And he’ll agree because it’s also a win-win for him – he has too many apples and wants mashed potatoes for dinner. A decentralized exchange works the same way – you can exchange, for example, ETH crypto (potatoes) for DAI (apples). SushiSwap is a decentralized exchange, which was made by cloning another exchange called Uniswap. What is different about SushiSwap is that it utilizes a token called SUSHI to incentivize users to make their other coins and tokens available for trade. This is called liquidity.
