Monetization strategies for NFT marketplaces range from transaction fees to premium subscriptions. Transaction fees are a common model where a small percentage is taken from each sale. Listing fees for creators can be another source of income, especially for curated marketplaces. Subscription-based models offer premium features or early access to exclusive content. Collaborations with artists or brands for special NFT drops can also generate revenue. Choose a strategy that aligns with your marketplace's vision and user base.
