# Background

* Seldom dexes are as functional as cexes in regards to fees, efficiency, user font and so on.
* Few dexes accept fiat deposits (credit card access).
* Suspected “efficient” money use and possible financial regulations make Cexes vulnerable towards crisis.
* A cheaper transaction fee (like cexes) incoporated dex is demanded.
* AMM create significant impermanent loss.
* No unified platform that aggregates data across the major exchanges and quotes the combined order book at the best price.
