Hello,
I am withdrawing from this bounty. I can’t continue due to personal reasons.
So this bounty will become unlocked. Since @NicolasFlamel has already done progressed much further with the work he has done, I think that if he wants to, he should request locking this bounty for himself. Taking into account @NicolasFlamel’s work, I think it also should be clarified or reviewed by the Original Council what the milestones should be. It was the OC that originally put out the bounty. In particular, if the grin-wallet integration is still part of one of the milestones. The OC and @NicolasFlamel can discuss this together with other issues and conditions.
