Hi, I can help you to build this platform. I have experience in build cryptocurrency exchange website. I made my self from scratch including wallet, market maker, kyc, etc. I'm really sure I can help you to build the same thing in here. I also have a team to do it nicely.
I can give you a demo & demo UI design site for my past crypto working.
Please consider my bid and let's talk over chat for more detail. Again, I have TEAM sir.
Regards,
Teguh
