Overview

What it means and why it exists

A reserve audit is an examination of reserve-related records, valuations, controls or financial statements within a defined audit engagement. The exact scope determines what assurance a reader can draw.

How it works

An auditor may inspect assets, confirmations from custodians, accounting policies, liabilities and controls, depending on the engagement. A financial-statement audit under applicable standards differs from an attestation covering specified balances on one date. Readers should check the report's period, subject matter, criteria, opinion and any exclusions.

Technical details worth understanding

For stablecoins, the key comparison is not only assets held, but also tokens outstanding and other claims against the same assets. Reserve composition can change after the report date. A bank confirmation can support that an asset existed without establishing its liquidity during a sudden redemption wave.

What can go wrong

The marketing phrase 'audited reserves' is ambiguous unless the underlying independent report is available. An auditor generally does not guarantee future solvency, asset market prices, legal redemption rights or that all fraud is impossible. Proof of reserves without liabilities can provide an incomplete picture.

Practical checks

Request the actual signed audit or assurance report, not just a 'fully audited' banner. Determine what period was tested, whether liabilities were included and whether restricted assets were excluded. A reserve balance on the report date does not remove subsequent liquidity, valuation or redemption-access risks for ordinary token holders.

Example

A merchant reviews a stablecoin issuer's published reserve report. It checks the date, whether the engagement is an audit or attestation, the tested liabilities and the auditor's conclusion before adopting a treasury exposure limit.

Comparison

An audit evaluates a defined set of financial information or controls; a reserve attestation may test narrower assertions. A blockchain balance screenshot or proof-of-reserves tree is not automatically either one.

Key Takeaway

For stablecoins, the key comparison is not only assets held, but also tokens outstanding and other claims against the same assets.
