Please tell us how you search for sellers you can trust? Because a work of art is an expensive investment and we must be confident in the integrity of the seller.
It seems to me that the best option for this platform is to work not with salers, but work with artists, creators of art directly without intermediaries.
but as I understand it, in the future the platform will be able to work with private sellers. An authentication section will be created for this purpose. It is likely that this will be a little later than the launch of the main platform.
This platform will be able to work both with sellers and with chain stores.
