What depth stands behind this price?

LIBRE against USDC · GAYCCW…7TF5CY

How much can this asset safely back?

The ceiling is the lower of two independent limits. Which one binds is the part a lender acts on, so both are shown.
  1. Low
  2. Medium
  3. High
  4. Critical — this asset

Criticalpartial confidence

A band marked partial is a floor. At least one high-severity check could not be evaluated, so the real band can only be worse than the one shown, never better.

These bands come from thresholds that were chosen, not calibrated

The thresholds were chosen based on the magnitude of the Blend incident of February 2026 and on conservative judgement, not calibrated against a set of incidents. Every flag is reported separately so that consumers can apply their own thresholds.

What this computation could not do

  • maxReachablePrice and costToMaxReachablePrice are null because an active pool is present: under a constant product curve the price tends to infinity as the base reserve tends to zero, so every target is reachable and a highest price has no meaning

What volume can it absorb before the price moves?

Three rungs at 2, 5 and 10 per cent, in each direction. The buy side matters for oracle manipulation and the sell side for liquidation.

What would it cost to move the price?

Read cost together with reachability: a figure on an unreachable rung says how far the book goes, not what the move costs.
Cost to move the price by each delta, through all venues and through the order book alone, with whether the target is reachable at all.

Reachability on the all-venues ladder is unconditionally true whenever an active pool exists, because a constant product curve has no upper price bound. The order-book-only column is the one that answers whether a target is attainable, and it is the one Keel itself uses.

How far the book actually goes

Furthest price the book reaches
not computed

Null by structure, not by failure: an active pool means every target is reachable and a highest price has no meaning

Cost to walk it that far
not computed

Null for the same reason as the price above

How has this moved over time?

A single reading cannot separate a thin asset from one that just got thin. This is a stored series, not the historical replay that health reports as unavailable — those are different endpoints.
