# Event 1

**VIP NFT Buy Back Event**

* **Frequency:** Occurs monthly, on the first of each month.
* **Mechanism:** Circularity Finance sells VIP NFTs in exchange for XDC and uses half of these proceeds to repurchase CIFI tokens.
* **Purpose:** The repurchased CIFI tokens serve dual purposes; they are used to replenish staking pools, and the remaining funds are allocated to purchase CGO tokens from Comtech Gold, contributing to the ‘proof of reserve’ protocol.
