The answer, from the board
STALE states age, not lateness: the newest report ReserveBeat holds for this token is older than the cadence expected for it, which can happen while the next report is not yet due.
| Report period | Firm named in the report | Assurance | Issued on |
|---|---|---|---|
| 2026-06 | BDO Advisory Services S.r.l. | EXAMINED | 2026-07-31 |
| As reported in Tether's attestation dated 2026-06-30, prepared by BDO Advisory Services S.r.l. | |||
| 2026-03 | BDO Advisory Services S.r.l. | EXAMINED | 2026-04-30 |
| As reported in Tether's attestation dated 2026-03-31, prepared by BDO Advisory Services S.r.l. | |||
A firm is named only where the report names it in its text layer; a firm never enters the board from outside the document. The assurance column is the level the report itself states. An attestation on reserves at one date is narrower than an audit of the issuer's financial statements, which these reports are not.

Questions
Common questions
Where do the answers on these pages come from?
Each page reads ReserveBeat's own board when you load it. Figures published by issuers pass through exactly as they appear in the attestation reports ReserveBeat parsed; anything ReserveBeat works out itself is labelled as computed and the calculation is written down.
Why is an answer sometimes empty?
Because ReserveBeat holds nothing for it. An empty cell is never filled with a zero, an estimate, or a figure carried over from somewhere else, and a whole answer is withheld rather than shown stale while the board is under review.
Do these pages define the terms they use?
No. Definitions live in the learn section and are written once. These pages answer questions whose answer is a figure or a state read from the board, and they link to the learn section for the vocabulary.
How often do the answers change?
Whenever the underlying board changes. Nothing on these pages is cached as text, so a new attestation report or a correction shows up on the next page load without anyone rewriting the page.
