# 4.1 NFT-Chain-Based Economy Model

The NFT-Chain-based economy of SCG directly reflects economic activities and user behavior in each game on the blockchain, creating a clear linkage between asset flow and gameplay. Multiple games within the SCG ecosystem—such as SoccerGO, GolfGO, BaseballGO, and Fishing\&GO—are all built on a unified NFT layer, guaranteeing interoperability and scalability of assets across different games.

The core of the economic model lies in NFT creation and utilization, along with a fee-based revenue structure. The main revenue sources include:

* NFT marketplace fees
* Token purchase transaction fees
* In-game item sales
* Season pass and advertising revenue
* Trading commissions

Players obtain Generated NFTs through gameplay and can combine and enhance them into higher-tier NFTs. The processes of payment, trading, and burning involved in this cycle serve as the central mechanisms that drive ecosystem-wide liquidity and asset circulation.
