Qualified CCDf Futures & Option subscribers may register to swap Agree Cash balances and CCDf licensing in face values through Sedna Certified serials verification accordingly.


Thanks to its pure lossless property nature as digital currency, CCDf balances may be smoothly switched into Agree Cash or vice versa, upon successful application of verification code.


However, this practice of swap shortcut is temporarily paused from July 1, 2020, according to the updated Policy of CCDf and Agree Cash.


This period is estimated to be two years from July 1, 2020 to June 30, 2022. During this period, CCDf subscribers shall exchange balances into ordinary cashes first, then swap into Agree Cash accordingly based on real time market exchange rate. The aim of this arrangement is to test real time applied values of Agree Cash and CCDf balances. 


Please note that varied tax obligations may arise under new settings when you switch Agree Cash and CCDf balances, effective since Jan 24, 2021.​
