Wait... so, your service is more to facilitate a list of prices in exchanges, where the transaction itself will be directly between us and the exchanges themselves (another user in case of a DEX and a company for a CEX)? You don't act as a middleman?
--image snipped--
You can check rates yourself. We aggregate exchanges and always provide the best to our community.
As implied by the image (snipped), the answer is yes you didn't take any fees from both parties, as the price on said exchange platform is exactly the same as what you put into yours. May I know how do you sustain your company, then? How do and where from your employee (no matte how small the team is) get paid?
