Transaction without wallet provider

#blockchain #javascript #webdev

Hey guys ! I'm currently working on a project, and i'd like to know if this is technically possible:

I'd like my user to create an account and be able to buy / sell NFTs on my platform ONLY without using any wallet provider (Metamask, Binance Wallet etc...).

I know that i can create an ETH address for them, and i've read some interesting stuff about Escrow, but no one seems to ever have wondered about this. Is it technically possible ?

Thanks a lot for your responses, have a nice day !
