Robinhood Chain produces blocks every weekend. The stocks behind your collateral do not trade on weekends, so the price feeds Corpus reads go quiet on Friday and stay quiet until Monday. Two different clocks, one position. Here is exactly what happens in between.
All times below are US Eastern, and they assume a feed that publishes during regular trading hours. Feeds that also publish during extended-hours sessions will shorten the quiet period, sometimes considerably.
The ordinary weekend
The market closes Friday at 16:00 and opens Monday at 09:30. That is about 65.5 hours with no new price.
Corpus accepts a price for 80 hours. So a normal weekend passes entirely inside the window, and nothing changes:
- Prices stay fresh the whole time. Markets are not badged stale.
- You can borrow, withdraw, deposit, repay and harvest as usual.
- Liquidation is permitted, and if your position crosses below a health factor of 1.00 it can happen at any hour of any day.
That last point surprises people. The protocol does not close for the weekend. It is simply working from Friday's closing price the whole time, so unless someone else's transaction changes your position, your health factor sits still until Monday morning.
The margin is not huge. Friday 16:00 plus 80 hours lands at Tuesday 00:00, which is 14.5 hours after Monday's open. If Monday's feed is late, or Monday turns out to be an unscheduled closure, a market can tip into stale before it ever reprices.
The three-day weekend
Add a Monday holiday. The market closes Friday at 16:00 and reopens Tuesday at 09:30: about 89.5 hours. The 80-hour window expires at Tuesday 00:00, nine and a half hours before the opening bell.
So on a long-weekend Tuesday morning, expect a Stale badge and this behaviour:
- Borrowing is blocked until the feed publishes again.
- Withdrawing collateral while you have debt is blocked. Withdrawing with no debt still works.
- Liquidation is blocked, for everyone, including against you.
- Deposits, repayments, harvests and credit claims all still work.
It resolves itself. Once the market opens and the feed publishes, the market is fresh again and everything returns to normal within a block or two. But if you were planning to draw USDG at 07:00 on a holiday Tuesday, you cannot.
We chose 80 hours knowing this. Stretching the window past a three-day weekend would mean trusting a price nearly four days old during exactly the period when the most can have happened. Refusing to act is the safer failure. The reasoning is in When the oracle cannot see.
Monday's gap
The real weekend risk is not the staleness rule. It is that prices move while nobody can see them.
A stock that closed at $200.00 on Friday can open at $170.00 on Monday. There is no path between the two prices on the chain — no gradual drift you could have reacted to, no intermediate level at which you could have topped up. There is Friday's number, then Monday's number.
If that gap takes your health factor below 1.00, you are liquidatable the moment the feed publishes, and liquidators watch feed updates for a living. You will not get a warning shot. Corpus's liquidations are partial, so a single event takes only the slice that restores a health factor of about 1.00 rather than half your position, but the slice still costs you the 5% bonus (7.5% on TSLA).
Work it through. Ten AAPL at $200.00 with 600 USDG of debt has a health factor of 2.00 and would need a fall past $100.00 to be liquidatable — an enormous gap, and you would be fine. The same ten AAPL borrowed to the full 1,000 USDG has a health factor of 1.20 and needs only a 16.67% fall, past $166.67. Weekend gaps of that size are not common, but they are not exotic either. One is an event; the other is a Monday.
What you can still do while it is dark
This is the part worth knowing: you can improve a position over a weekend, you just cannot enlarge it.
Depositing collateral needs no price, so it is never blocked — not by staleness, not by a holiday. Repayment is never blocked either. If you get nervous on a Sunday, you can add collateral or pay down debt at any hour, and both raise your health factor immediately. What you cannot do while a price is stale is borrow more or pull collateral out from under a debt.
A short Friday checklist
- Look at your health factor, not your LTV. The app also shows the price fall to liquidation, which is the number that matters across a gap.
- Assume no intervention. Decide what you are comfortable with for 65 hours, or 90 across a holiday, with no chance to react partway.
- Check the calendar. A market holiday on the Monday means a stale Tuesday morning and no borrowing until the bell.
- Remember the yield is zero. Nothing is quietly reducing your debt over the weekend. That will change when an earning vault is connected; today, a position only improves if the price rises or you repay.
The protocol will do exactly what it says over a weekend. It is the market that does the surprising part.
