SushiSwap (SUSHI) is an example of an automated market maker (AMM). An increasingly popular tool among cryptocurrency users, AMMs are decentralized exchanges which use smart contracts to create markets for any given pair of tokens. SushiSwap launched in September 2020 as a fork of Uniswap, the AMM which has become synonymous with the decentralized finance (DeFi) movement and associated trading boom in DeFi tokens. SushiSwap aims to diversify the AMM market and also add additional features not previously present on Uniswap, such as increased rewards for network participants via its in-house token, SUSHI.
