KIMCHI Token is a fork of Yuno and Sushi, the latter of which is itself a fork of Uniswap.
KIMCHI is new enough that it’s hard to ascertain how exactly it differs from its mother token, SUSHI. Sushiswap issues the eponymous SUSHI tokens as a way of incentivizing people to contribute liquidity to the platform.
The platform also gives a cut of the trading fees to users who lock their tokens into a smart contract, meaning they can’t touch it for a specified period.
