Thanks for the heads up re the USDC Back Door. Always good to know what the potential instabilities of these "stable coins" are!
Re the Quint - thanks for searching for it! I found its website: https://quintric.com/ I first heard @Stan promoting it on @BlueRockTalk 's youtube channel. I think he may have said it was powered by the Bitshares blockchain on the back-end. He's one of its creators and I recall him saying that each Quint is backed by actual physical gold held in a vault in Utah. That facet of it definitely sounds pretty stable.
