What kind of process will they do when it comes to KYC? Will they use their own Identity to access your account. Or will the owner himself submit their identifications using your account?
Again, everything is very individual and depends on the situation. But as a rule, KYC is required when the owner does not want to send his documents to the exchange, or when the owner does not have such an opportunity. Because there are quite a few countries in which it is impossible to pass verification.
Does that mean you are making KYC for the user? Lets assume my funds a stuck at an exchange and they are asking for KYC. What will you do? Will you provide them with KYC data like a passport?
