i have already sent 5 or 6 times utn from address to address on mainnet. the speed is great. a transaction took 2 seconds then the utn arrived on the other address. and everyone can test it if the person has some utn and some U on the wallet. U = gas .

and a mainnet address you can create in 3 minutes. this is also super simple
Yes, everything works. But, in my opinion, the system is not very user friendly. I find it rather difficult to understand this. It is necessary to refine the product, so that the use of the system would be simple for everyone.
