# Platform Fees

**Transaction Fees for Opening and Closing Positions**

Within the CVI and UCVI platforms, traders incur a fixed fee for each transaction, applicable to both opening and closing positions. The heightened fees for UCVI reflect its amplified profit potential, as UCVI grants roughly threefold the exposure compared to CVI. These transaction fees are instrumental in generating real yield for GOVI stakers.

* **CVI Open Fee**: 0.14%
* **UCVI Open Fee**: 0.35%
* **CVI Close Fee**: 0.14%
* **UCVI Close Fee**: 0.35%

**Funding Fee Dynamics**

Funding fees, calculated hourly based on the CVI Index value, are allocated to Theta Vault liquidity providers. A noteworthy aspect of this mechanism is the inverse correlation between the CVI value and the funding fee percentage; a higher CVI value corresponds to a lower funding fee percentage. Adjustments to the funding fee rate are responsive to CVI Index value fluctuations and the utilization ratio.
