BLOCKCHAIN LAB BRIEFING · STABLECOINS

A Reserve Attestation Is a Snapshot. It Is Not an Audit of Solvency.

Issuers publish assurance reports that say a stated reserve matched a stated liability at a moment in time. That sentence is narrower than people hear. It does not, by itself, prove the quality of assets or what happens in a run.

All briefings

01

What happened

Large dollar-token issuers point to accountant reports. The careful ones are attestations or agreed-upon procedures: at a date, tokens outstanding and a schedule of assets. They are not, unless the report says so, an audit opinion on a full set of financial statements, and they are not a going-concern opinion.

Tether publishes reserve reports and describes them on its transparency page. Circle publishes reserve and attestation materials for USDC. The documents differ. They should be read as documents, not as a shared industry badge called audited.

02

Why it matters

A treasury policy that says we only hold audited stablecoins is usually unenforceable, because the word audited is doing work the report does not do. The enforceable policy names the report type, the date, the assets you accept, and the redemption test you have run.

An attestation can be accurate and still show assets a conservative treasury would not call cash: secured loans, metals, or deposits at banks you have capped.

03

The operating layer

Read the opinion letter, not the infographic. Note the date, the standard, what was not in scope, and the categories of assets. Compare tokens outstanding to assets that can pay redemptions on the timetable your payouts need.

If the report is weeks old, treat it as stale the way you would treat a stale oracle. Freshness is part of the control.

04

What is verified

Issuer transparency pages exist and describe report cadence. Blockchain Lab has not re-performed any procedure and does not rank issuers.

05

What remains unclear

Whether a given quarter’s report is an attestation, a review, or an audit, in the accountant’s words. Which asset categories would be ineligible under your own policy.

06

The catch

Publishing a report is better than publishing nothing. It is still not solvency, not a government guarantee, and not a reason to remove the fiat fallback.

No issuer is recommended or excluded by this briefing.

WATCH

What builders should watch

  1. 01The accountant’s own description of the engagement.
  2. 02Asset categories, not the headline total.
  3. 03The age of the latest report against your freshness rule.

BOTTOM LINE

Quote the report type accurately. A snapshot of reserves is not an audit, and an audit is not a redemption.

Sources

Blockchain Lab uses public social posts as reporting leads, not as proof. Every published briefing is assessed against primary sources, available documentation and relevant technical context. Social engagement is not used as evidence of the underlying claim.
