Virtual Land Ownership Contract

What it does:
Enables users to mint, buy, sell, and manage virtual land parcels as NFTs, providing verifiable ownership and automated royalty distribution for creators or developers.

Why it matters:
Ensures transparency in virtual property ownership, prevents fraud, allows monetization through sales or development, and supports metaverse ecosystems.

How it works:

Virtual land parcels are minted as NFTs with metadata (location, size, features)
Ownership can be transferred or sold, with automated royalties for creators
Developers can define usage rules or build structures on parcels
Integrates with Gaming Asset Ownership, NFT Marketplaces, or Play-to-Earn Reward Engine
Dashboards show parcel ownership, transaction history, and development rights
Supports cross-platform virtual land marketplaces and verifiable provenance
