Your xStock trades 24/7, but the underlying equity closes overnight. Holdline watches your Kamino loan while the market is shut and, if it drifts toward liquidation, repays from a reserve you fund and own. Self-custody. You keep the upside.

The overnight gap is real
In the last 12 months, TSLA, NVDA and AAPL opened more than 5% away from the prior close multiple times — overnight gaps a sleeping leveraged borrower could not react to. A tail event, and exactly the kind you insure against. (Exact count + dates: evidence/overnight-gaps.jsonl, recomputable via scripts/overnight-gaps.ts — a rolling-window figure, so we don't hardcode it here.)
