# Fee Structure – Sustainable Economic Model

To ensure operational sustainability, the CUDIS ecosystem employs a balanced fee model:

* **Upload Fee** – A small CUDIS token fee is charged for on-chain data storage, covering decentralized storage costs.
* **Listing Fee** – A nominal fee applies when minting and listing data NFTs on the marketplace.
* **Processing Fee** – AI-driven data analysis and secure computations incur CUDIS-based fees, supporting CUDIS Processing Nodes (CPN).
* **Marketplace Transaction Fee** – A percentage fee on NFT sales helps sustain ongoing platform operations.
* **Project Launch Fee** – A fee on new longevity asset launches funds future ecosystem development and innovation.
