It might seem as if Verge is in a bit of a grey area because of its anonymity aspect, however, Verge is completely legal as of the time of this writing. Verge has never been mentioned by any regulators as well as being a potential threat to the public safety, or warned that its usage could be deemed as illegal. As it stands in current day situations, Verge is legal and available via open source development. It's not necessarily a closed-door operation as many would expect.
