Ok, so a stablecoin means, that the holder gives an unsecured, zero-interest loan to a company with unknown credit worthiness. It's "stable" because a $1 debt stays a 1$ debt. That's a nice spin on zero interest. It's not what I'd call a currency. Or sane, reasonable, sensible, ...
I note that tether is known for not allowing audits. Are you for real?
The other option is that the loan is collateralized in crypto. And you can't actually redeem the stablecoin for money, you can only get crypto that trades for $1, allegedly. On the liquity site I wasn't able to see how the price is determined. I did see that there is a redemption fee of variable, unknown size. I'm not quite clear how that is supposed to be sane.
