New NFT Marketplace

Hello everyone,

I am looking to start my own NFT marketplace soon. However, there are some questions concerning the logistics I simply don’t have the answers to as of yet.

These are as follows:

How is security ensured on the platform ? What service providers need to be contacted and what can be done in house ?

Do commissions end up in a crypto wallet or a bank account ?

Are those funds accessible straight away ?

Will royalties still apply when an NFT posted originally on my platform is sold on another afterwards (e.g. Opensea) ?

Will proceeds from the marketplace end up as cryptocurrency or FIAT currency ? If FIAT currencies are involved, will a payment gateway need to be integrated ? (tied to 2nd question)

that’s a lot of questions… what kind of research have you done on your own trying to answer these questions?
