/*YFIG is the abbreviation of YFIGroup. 
YFIG's success is due to the core technology from YFI. 
The development core team comes from the United States, China, and South Korea.
The YFI technology is independently forked and upgraded to a cluster interactive intelligent aggregator, 
which aggregates multiple platforms Agreement to realize the interaction of assets on different decentralized liquidity platforms.*/
