Sushiswap is a decentralized exchange
that allows users to swap tokens, provide liquidity and earn rewards. It is
based on the Ethereum blockchain and uses an automated market maker (AMM) model
to facilitate trades. Sushiswap also has a governance token called SUSHI, which
gives holders a say in the development and direction of the platform. 1,800 ETH
worth over $3.3 million has been hacked from the platform. SushiSwap's head developer Jared Grey
said that the exploit happened because Sushi's RouteProcessor2 contract has an
approval bug.
