How does Artrade sustain itself?

Artrade earns revenue through a commission of 0.22% on all $ATR token volume on decentralized exchanges.

Also, Artrade is not directly purchasing the items. The items are purchased with the DAO wallet, which is an inital $ATR supply attributed to this purpose.

So in practicality the items are purchased by the $ATR community.

While fees payed by traders on decentralized exchanges are used to develop the marketplace.
