Watermelon Finance is the first DeFi project for AMM liquidity mining on the IOST blockchain. On October 18, 2020, it launched its own AMM decentralized exchange. Within a week, it started XUSD minting and allowed liquidity sex mining. Watermelon Finance has completely decentralized community autonomy, and holders of XG tokens have full governance rights of the platform. The total amount of XG is 4 million pieces, which are obtained entirely through AMM liquidity mining. 2 million will be issued in 40 days, and then the remaining 2 million will be issued in 200 days. The development team only charges 10% of the excavated XG for the long-term maintenance of the platform, and all business income in the platform will be used to repurchase and destroy XG.
