# Buyback Guarantee

To ensure the rights and interests of our global community users to the greatest extent, we have established a refund mechanism.

## Refund Window

The refund window Will open 6 months after the start of TGE(Token Generation Event). The duration of the window is to be determined.

## Refund Terms

The refund policy applies to retail users only. If users are dissatisfied for any reason, they may apply for a refund. We will unconditionally refund 80% of the initial payment amount. At the same time, the user needs to return all received benefits and licenses.
