I keep on thinking about the name of the project which is fairninja. I really am quite puzzled as to why this has become the name for their project. Maybe it is because they see themselves as fair or wanna be fair on fheir platform or maybe it is Because their platform aims to be fast just like a ninja. I don't know,aybe someone cam guess it?
You are quite right with your guess. They want to be fair and want to be fast. They also want to have an anonymous transaction that's why they prefer Ninja on their name. Anonymity was preferred by Crypto users for every transaction made.
