Not to be rude but I guess the OP is just wasting their time in here. There had been a lot of tons of instant crypto exchanger such as Best Change and the newly released Uniswap. With a lot of projects having the same idea and features as the others, I keep telling them, 'what is your difference with the other platforms?'
Also, they mentioned that they've used only the listed exchanger's widgets to be look up values in their system. I guess this is a good idea but not if they haven't integrated it that well, making their platform irresponsive with each and every tests of swapping pairs. Overall judgement, I guess they are still aren't ready to be public, and public must be aware that their system was still faulty. Be cautious.
