1. Conversion fee

   XREX charges a fixed conversion fee of 0.05% for its conversion function. The conversion fee shall be calculated based on the type and amount of the asset to be converted, and shall be directly deducted from the total amount of such asset before the conversion is executed. The net amount after deduction of the conversion fee shall be converted based on the conversion quotation provided by the system.

   Before you confirm a conversion transaction, the system will display the applicable quotation, the amount of asset to be converted and the estimated amount of asset to be received. You may also click the information icon next to the quotation to view the applicable conversion fee rate and fee amount for the transaction. XREX will not charge an additional conversion fee separately for the same conversion transaction.

   You must confirm the transaction within the quotation validity period. If the quotation expires before confirmation, the quotation will become invalid and you must request a new quotation.
