Book composition · auto-observed
A lead pool takes the bulk of this book at present, trailed by smaller venues on that same chain.
A bond, priced in its own dollar
A locked token against its liquid base is one of the cleanest ratios a market can print: everything the two share cancels out, leaving one thing visible, what the market charges for the lock. The book here has quoted the bond directly in its base dollar, which makes that ratio a print rather than a derivation.
Instruments with maturities are allowed to trade away from face; that is what a discount rate looks like in price form, not a malfunction. Whatever the quote side of the book holds, each leg resolves through its own measured feed before the dollar figure above is formed; a USD0 leg runs in series through the base token's page, two pages of this catalog working together.
The base token's page describes the plain dollar; this one describes the claim with a clock on it. Reading them together is how the pair makes sense.
How the discount became public record
In early 2025 the redemption terms of this instrument changed publicly; the market repriced the lock hard, with the token spending long stretches well below its dollar face. That episode is settled history, documented across public sources.
What a feed owes such a history is neither commentary nor comfort, just continuity: the same measured ratio before, during, after. Whoever needs to reconstruct a mark from those months, or defend one today, finds the venues and the blocks here.
The instrument itself carries on. Whatever the lock is worth this week is what the pools below say it is worth, weighted and dated.
A sibling with a market of its own
For a sibling token, the market has been no afterthought: the bond has cleared heavier turnover than many better-known dollars manage. A locked claim people actively trade is a locked claim people actively reprice, which is what makes its feed worth keeping.
The plus signs in the name are dropped by most systems that handle it, so this token is usually reached through the USD0 page rather than on its own. The two pages are built as a pair on purpose: base and bond, each linking the other, sharing one measurement style.
However the book is shaped in a given week, resolution follows the same rule: every quote leg is carried through its own feed until plain dollars appear.

Risk desks monitoring lock discounts
The distance between bond and base is this instrument's whole risk surface; both sides of it are published feeds here.
Credit desks weighing USD0++ collateral
Collateral that can trade below face demands the traded level with provenance; this page exists for exactly that demand.
