Key features of a metaverse shopping mall might include:

Virtual Storefronts: Brands and retailers could create virtual representations of their stores, allowing users to browse and explore products in a digital space.

Social Interaction: Users may interact with each other through avatars, making shopping a social experience by allowing friends or family to join them virtually.

Immersive Experiences: Enhanced by virtual or augmented reality technologies, users can experience products in a more immersive way before making a purchase decision.

Digital Currency: Transactions within the metaverse shopping mall could involve digital currencies or blockchain-based transactions.

Customizable Avatars: Users may have the ability to create and personalize digital avatars to represent themselves in the virtual shopping environment.
