SUN.ioSunPump

Calculation Service

SUN.io Smart Routing Calculation Service implements full graph search on SunSwap V1, SunSwap V2, SunSwap V3, PSM, and SunCurve by building contract mirrors on the server. It sorts the paths based on the amount of tokens exchanged and returns the top three paths that yield the most tokens to the user.
