* No fees for opening or canceling unmatched orders.
* **Trading fee rate:** 0.125% of the trade volume for each party if the orders are matched.
* **Cashout fee rate:** 0% (The user who used the cashout feature is only charged the trading fee).
* **Refund fee rate:** 0.125% of the trade volume when both parties fail to settle the matched orders.

\*Specifically: **V (trade volume) = P x A**

**P:** Token price at the time of order matching.
