Circulating supply is live via DefiLlama; peg mechanism is DefiLlama’s factual classification. Attestor, cadence and reserve composition are drawn from each issuer’s public transparency page (linked). “Last period” and “next window” describe the reporting rhythm the cadence implies, not a claim that a specific report was filed on a given day. roo2ya does not restate reserve dollar figures or backing ratios — open the issuer’s primary report for those.
The Aperture
Reserves, in focus
Near lens + far lensReading a stablecoin at two focal lengths
The near lens is what an issuer discloses today: the tokens in circulation right now (the live figure in the table above) and where it sits in its reporting rhythm. It answers a narrow, checkable question — for the last reporting period, did an independent accountant confirm the reserves matched the coins outstanding? The most recent report on the issuer’s own page is the detail you can hold in your hand.
The far lens is what that backing actually means. An attestation is a point-in-time snapshot, not a continuous audit; cadence matters (monthly beats quarterly for freshness), and what sits in the reserve matters more — cash and short T-bills behave very differently from crypto collateral or hedged derivatives under stress. On-chain backing you can verify live is a different model again. Quality is the composition, the attestor’s independence and the consistency of reporting over time, not a single headline number.
Explainer
How to read a reserve attestation
A stablecoin promises to be worth a dollar because something backs it. “Reserves” are the assets an issuer holds against the coins in circulation; an “attestation” is how outsiders get to check that claim. Understanding the difference between the two is most of what it takes to read this page well.
An attestation is an independent accountant’s point-in-time confirmation: on a stated date, the issuer held reserve assets at least equal to the value of the tokens outstanding. It is narrower than a full audit, which is a broader, standards-based examination of an entity’s financial statements over a period and ends in an audit opinion. Most stablecoin issuers publish attestations — monthly or quarterly — rather than continuous audits, so the useful habit is to open the report and see exactly what was tested, by whom, and as of when.
Three things separate strong reporting from weak. First, cadence: a monthly attestation is fresher than a quarterly one, and a long gap since the last report is worth noticing. Second, composition: cash and short-dated U.S. Treasuries are the most liquid, predictable backing; crypto collateral, hedged derivatives or tokenized assets can be sound but behave differently in a squeeze, which is why the reserve column above describes what each issuer holds rather than reducing it to one number. Third, the attestor: an independent, reputable accounting firm signing the report is the check that gives it weight.
On-chain issuers take a different route: their collateral lives in public smart contracts, so anyone can verify the backing live from the blockchain instead of waiting for a periodic report. That transparency is real, but the collateral is often crypto or tokenized assets rather than cash — a different risk profile, not automatically a safer one.
roo2ya shows you the live circulating supply and the shape of each programme — who attests, how often, what the reserves broadly consist of, and when the next report is due — and then sends you to the issuer’s own transparency page for the figures. We deliberately do not restate reserve dollar amounts or backing ratios here, because those change with every new report; the primary source is always the issuer’s to publish, and it is one click away in the table.
FAQ
Reserve attestations, explained
What is a reserve attestation?
An attestation is an independent accountant's point-in-time confirmation that an issuer held the reserve assets it claims, matched against the tokens in circulation on a specific date. It is narrower than a full financial audit: it confirms balances on one day, not an ongoing opinion on the issuer's financial statements or internal controls.
How is that different from a full audit?
A full audit is a broader, standards-based examination of an entity's financial statements over a period, ending in an audit opinion. Most stablecoin issuers publish monthly or quarterly attestations rather than continuous audits, so read the report to see exactly what was, and was not, covered.
What does "on-chain" mean here?
On-chain issuers hold their collateral in public smart contracts, so anyone can verify the backing live from the blockchain rather than waiting for a periodic report. That is a different transparency model, not automatically a better or worse one; the collateral itself is often crypto or tokenized assets rather than cash.
Why does roo2ya not show a backing ratio or reserve dollar figure?
Those numbers come from each issuer's own reports and change with every new attestation. Rather than restate a figure that could go stale, we link straight to each issuer's primary transparency page so you read the reserve breakdown from the source. The circulating supply we show is live from DefiLlama; the reserve composition and figures are the issuer's to disclose.
What do the reporting period and next window columns mean?
They are the reporting rhythm implied by each issuer's stated cadence, computed from today's date: the period that has just closed and the window the next attestation is expected to cover. They describe the schedule, not a claim that a specific report was filed on a specific day; open the issuer's page for the actual publications.
