CUSDO/USD price feed
cUSDO spends most of its life at the issuer's window: minted and redeemed against OpenEden's treasury vault, compounding quietly as yield lands. Its public market is small by design, yet it is where the market itself gets a say.

Book composition · auto-observed
A single active pool carries this book at the moment; the aggregate tracks it directly.
The window and the thermometer
Instruments like this are built around a primary channel: subscribe at the issuer, redeem at the issuer, value tracking the vault behind it. Public trading is an afterthought by design, which trackers confirm by reporting daily volumes in the hundreds of dollars.
An afterthought still matters. The vault states what the token should be worth; the market shows what a holder can get for it right now, without an appointment. Most days the two agree. The value of an independent reading is concentrated in the days they might not.
So the measurement here is deliberately modest: a small public book, read at stated blocks, taken at whatever size it genuinely holds.
Reading a thin book
Thin books reward a careful read rather than a rounder number. The feed publishes depth per side because exits are what holders of a window instrument care about: what a seller can get without an appointment, in size the book will actually absorb, is precisely the number the vault cannot state.
The token's price climbs by construction, a compounding wrapper doing what its name says, so a level above one dollar is the design working rather than a premium to explain. The pages of its accruing neighbors in this catalog tell that mechanism's story in full; here one sentence suffices.
One naming note: cUSDO is OpenEden's compounding dollar, unrelated to the phone-first cUSD that also lives in this catalog. Beyond that, the page keeps to its narrow job: the public price of a mostly off-market instrument, kept current for whoever needs it.
Who runs on this rate
Treasuries marking RWA wrappers
A vault value is the issuer's number; a defensible mark sometimes needs the market's second opinion, which lives in cUSDO's public book, however small.
Risk desks watching window versus market
Divergence between vault value and pool price is the early signal for instruments like this; the pool half is published here.
Integrations needing an independent reference
Anyone listing cUSDO gets a reading taken outside the issuer's own systems, with its venues named and every level dated.
