Most important question for loopers: what happens upon expiry?
In a nutshell: roll over if liquidity supports, otherwise unwind enough to satisfy lender requests, then roll over the remaining.
Most loans will simply be rolled over - to same or better fixed rate, or to variable, if the borrower chose so.
When liquidity is not available for a roll over, we unwind just enough to satisfy the queued withdrawals and then roll over the remaining of the debt.
For a token like AUTO, unwind to YLDS is without slippage, so the expiry is painless.
This the most elegant design we could think of.
It feels open term.
