RAI/USD price feed
RAI is the catalog's deliberate outlier among dollars: a stable asset with no dollar peg at all. Its target drifts by design, set by a controller responding to market pressure, so this is a stability instrument whose correct price is not one dollar.

Book composition · auto-observed
Right now one active pool stands behind this pair; the aggregate mirrors it as is.
Stable without a peg
Pegged dollars measure success as distance from one. This one measures it as damped volatility around a moving target, which means the usual depeg arithmetic simply does not apply to it.
That changes what a reader should take from this page. The traded level against the dollar is a genuine market price with room to move and comparing it to the system's own target is where the information lives.
The reading here is the market half of that comparison, taken from the venues that trade it.
