Zhile, Ora will not use QORA SC due to the uncertainty of source code release date and also for possible traps. Ora team has decided to use a more established sc and as per Nio's previous post, ORA is now in the planning & designing phase. It will take some time, definitely, therefore a few "get to know ORA programmes" will be launched from time to time until the wallet is released for which we will need your support!
