Such a great hunt man @yandot! I heard this one actually from Crowdin.

Well, this project is great to know thst is being made an open source. A promising mission which this project aims to achieve and that is by risk free terms when conducting payment. Would be glad to see the success of this project knowing that this one is built on blockchain. To top it all, it is a decentralized one meaning the people has the voice and control.

Speaking of downside, actually, none for this project.
