Uniswap describes a vision of a fair decentralized trading protocol: on the one hand, anyone can exchange two paired tokens anytime and anywhere; and on the other hand, it uses fair incentives to encourage everyone to provide liquidity for trading. At present, UNI’s token incentive mechanism is only for four trading pairs. SushiSwap has 100 trading pairs, but only the liquidity providers (LPs) of 18 trading pairs can get the governance token Sushi as a motivation.
