When you deposit UST into anchor, you are given aUST in exchange. When you want to get your money back, you then return the aUST.
Well, in the meanwhile, why wouldn’t we be able to exchange the aUST into other assets? The only requirement being that you need to reconvert to aUST in order to get your deposit back. Right now when you attempt to swap aUST for another asset, you are denied.
Unless I am understanding Anchor totally incorrectly, the 20% APR does not require the aUST to sit in the depositer’s wallet, right?
