We don’t have to reinvent the wheel here!
When you reissue the new Luna Tokens Just use the swaps to exchange ratios… for example 5:1 or 100:1. Simply burn the old Luna tokens.
Instead of using UST just partner with a reputable collateral backed stable coin and use that in USTs place.
The yields would be lower but you at least wouldn’t have to scrap a pretty good ecosystem and start new.
Simply remove the broken part and replace it with a good one and build from there.
