Nights and weekends
What the protocol actually does at 3 a.m. on a Sunday — the same thing it does at 10 a.m. on a Tuesday, from the same sources, with a different number of them answering.
There is no closing bell inside Fyber. A branch's price is a composite, recomputed every hour from the same set of sources at 3 a.m. on a Sunday as at 10 a.m. on a Tuesday. What differs between those two hours is how many of those sources answer and how well they agree. That, and nothing else, is what LIVE24, DEGRADED and FROZEN name. The rules themselves are in Markets never close.
Where the price comes from, at every hour
The composite is the median of three groups of sources:
- the time-weighted averages of qualified on-chain pools;
- signed perpetual and index feeds;
- twin-token markets, where the same exposure trades under another ticker.
No group may weigh more than half the total, so no single kind of source can set the price on its own. The computation runs on the hour, every hour, and does not consult a calendar.
The hour, on one screen
| Regime | What the sources are doing | What changes for you |
|---|---|---|
LIVE24 | At least two independent groups agree, one of them not a reporter | Nothing. Standard ratio to borrow, no haircut, liquidations absorbed by the Stability Pool. |
DEGRADED | Sources have dropped out, disagree beyond 3%, or are too correlated to count as independent | A valuation haircut on borrowing and withdrawing, up to 30% on tier 1. A fall must be confirmed and persistent before anything acts on it, and the delay between flag and execution is longer. |
FROZEN | Too few independent sources remain | Nothing that needs a price runs. Repay, add collateral and close stay open. |
This is a statement about sources, not about hours. A quiet Tuesday afternoon with two feeds down is DEGRADED; a Sunday night with the pools deep and the feeds signing is LIVE24.
What runs in every hour
- Liquidation runs in every hour. In
LIVE24and inDEGRADEDthe Stability Pool is the taker. InFROZENnobody is, because nothing that needs a price runs. - Redemption runs in every hour, at the ordinary floor of 0.5% plus the base rate plus up to 2% when confidence is low, and you are served at the higher of the composite and the banded on-chain price.
- You can still borrow and withdraw, subject to the haircut in
DEGRADED. - You can always repay, add collateral and close. These read no price at all and cannot be paused by any key.
- The PSM works in both directions, at 0.05% in and 0.20% out, and
repayWithUSDGcloses a debt with plain dollars at any hour. Rules R-1.5.1, R-8.3.1
Guarantee
Your liquidation threshold is the same number in every regime: 115% on tier 1, 120% on tier 2. Lower confidence never raises it and never lowers it. Caution is bought with proof and with delay, never by moving the threshold under a borrower.
When the sources thin out
In DEGRADED a fall is not acted on the moment it appears. It has to persist — 3 hours on a single qualified source, or agreement within 3% between two independent ones — and the recognition band caps how deep a fall the protocol will read at all, at 4% on tier 1 and 6% on tier 2. The band is a constant and does not widen with time.
The haircut applies to borrowing and withdrawing only. It never touches an existing position's threshold, never forces you to act, and returns on its own the moment the sources come back.
What you should actually do
| If | Then |
|---|---|
| Your ratio is comfortably above 115% | Nothing. You will not be notified and nothing will happen. |
You want to borrow more while the branch is DEGRADED | You can, at the ratio shown live in the interface, with the reason for it shown next to the number. |
| The price falls against you | You are notified when the persistence clock starts, before anything can execute. Repaying and depositing work at that hour. |
| You want no exposure to any of this | Close the position. close() works in every regime. |
Rules R-15.1.6, R-15.3, R-1.1.5
Risk
None of this removes gap risk. A price can move a long way between two computations, and the recognition band absorbs at most 4% of it on tier 1. Beyond that the gap lands whole, and it is the 115% threshold, with its 6.09% cushion, that has to absorb it.
Risk
The other side of that gap is held by Stability Pool depositors, who absorb in hourly slices everything a move made liquidatable, on a composite that can be wrong. Nothing on the borrower's side of this page is a promise to them. See Earn.

Markets never close — your guarantees
The protocol runs 24 hours a day on a composite price. What changes from hour to hour is how much confidence the protocol places in that price, not what you are allowed to do.
Corporate actions
Splits, dividends, mergers and delistings — what the protocol does automatically, what it deliberately does not do, and the one case that can cost you.
