Hns.chat is a encryted messaging app using handshake as login and username.
To start you will need a handshake name or Subdomain. Alternatively you could also get a free subdomain of the few available tlds. If you have that, you will need to set the txt record provided by hnschat and then click verify.
Thats it, you're good to go, try it out by writing a Message to 🐺.degen (xn--fp8h.degen)
