Is MakersPlace free?

I'm curious about MakersPlace and their platform for digital art. Do they offer their services for free, or do users have to pay a fee to access the platform and participate in transactions? It would be great if they had a free tier to attract new users and let them explore the platform before committing to a paid subscription. However, I understand that running a platform like this requires significant resources, so I'm also open to the possibility of a paid model. I'd love to hear more about their pricing structure and what kind of value they offer to their users.
