It's a decentralized chat. NKN is a network on a blockchain. nkn.org. I am not a part of the NKN team. You might be able to reach me on #d-chat (lowecase). Permissions: - all urls: it's decentralized, so the connections go all over the place. - storage: Need to save your open chats, and the NKN wallet. Locally. - unlimitedStorage: Not sure if this one is needed, but what the heck. Note that the support email is a public email (anyone can view it), so don't send anything you wish to keep personal.
