Crypto.com Proof of Reserves vs Coinbase audited earnings: The same thing?

No: Crypto.com's reserve certificate and Coinbase's audited financial statements are evidence of a different nature. They are verified by different institutions and cover different contents.

The reserve certificate report issued by Crypto.com only shows specific assets held by a specific wallet at a certain point in time, and does not involve the company's liabilities. Coinbase's financial statements, audited by Deloitte, cover debt, related transactions and internal controls, and are not limited to cryptocurrency holdings-but even so, it does not prove that the exchange can withstand a bank run-style wave of withdrawals.

What did Mazars actually check and when it stopped

According to CoinDesk and Time magazine, before December 2022, accounting firm Mazars issued reserve certification reports for Crypto.com, Binance and KuCoin. On December 16, 2022, Time magazine reported that Mazars had suspended all such work for crypto customers around the world. A Mazars spokesperson told reporters that the suspension was due to "concerns about how the public will interpret the reports." A Binance spokesperson told Bloomberg News that Mazars has "indicated that it will temporarily suspend cooperation with all global crypto customers," so Binance is currently unable to continue working with Mazars. Both Crypto.com and KuCoin have expressed their willingness to cooperate with other audit institutions.

The market responded to the news. According to Time magazine, Bitcoin fell 2.8% on Friday, and Binance BNB token fell 4.8%. The same article quoted CryptoQuant data as saying that in the previous two weeks, US$554 million in stablecoins and more than US$2 billion in bitcoin and ether had flowed out of centralized exchanges, but the scale of withdrawals was basically stable compared to the large-scale withdrawal after the FTX crash.

Mazars-style reporting was never intended to show the liability side of the balance sheet. CoinDesk quoted Joseph Collem, general counsel at Bitcoin.com, as explaining that exchanges "should hold the asset for users on a 1:1 ratio" to achieve direct verifiability, but he added that "without proof of liability, proof of reserve is almost meaningless." Francine McKenna, a lecturer in financial accounting at Wharton, told CoinDesk that such reports are essentially a matching exercise-mapping exchange internal customer databases to blockchain entries-and warned that companies undertaking such work face "very high" reputational and legal risks.

Current Disclosure Status of Crypto.com

None of the four sources reviewed in this article mentioned that any accounting or audit firm has reviewed Crypto.com's reserves since Mazars withdrew in December 2022. The CryptoSlate article republished via Cryptonews on August 8, 2026 stated that Crypto.com currently provides a "Merkel Tree based verification interface"-a system that allows customers to confirm that their own balances are included in the data set used to calculate the exchange's total reserves, but it cannot be confirmed that all customer balances are included, nor can it reflect the exchange's liabilities. This CryptoSlate/Cryptonews article is the only source of information describing the current mechanism of Crypto.com and does not mention any external accountants participating in the production.

The same article explains the limitations of relying solely on the reserve amount panel from a general perspective (rather than specific circumstances at Crypto.com): It illustrates that if a panel shows holding US$10 billion in cryptocurrency, this does not indicate that the underlying exchange owes US$8 billion, US$10 billion or US$15 billion to creditors, nor does it indicate whether other parties have made competing claims for the same asset. The article also cited warnings from the U.S. Public Company Accounting Oversight Board (PCAOB), which noted that reserve certification reports vary widely and are outside its audit oversight, and warnings from the U.S. Securities and Exchange Commission (SEC) chief accountant, who said such certification businesses typically examine a narrower range of evidence than a comprehensive financial statement audit. In the version of the article reviewed for this article, neither of these warnings directly quotes the original text or links to the original document.

What Coinbase's Deloitte audit actually covers

Coinbase is a U.S. listed company that both CoinDesk and Time magazine reported was audited by Deloitte, one of the Big Four accounting firms. CoinDesk quoted McKenna as noting that top firms like Deloitte "prefer to work with large pre-IPO or public companies," while companies like Mazars or BDO Milan (Tether's auditor) focus on directly auditing crypto-native companies.

The CryptoSlate/Cryptonews article describes the actual difference as follows: As a listed company, Coinbase's annual declaration documents cover debt, collateral, derivatives, commitments, subsidiaries and related transactions in addition to cryptocurrency holdings. Deloitte's audit report covers both financial statements and Coinbase's internal control over financial reporting. This is much broader than a mere asset snapshot. But the same article made clear that none of these guarantees that Coinbase will be able to avoid withdrawals, management errors or technical glitches-audits only test whether numbers and internal controls are fairly stated, rather than judging whether the company can withstand future shocks.

Common misunderstandings

Industry reports, including some sources for this article, sometimes loosely use the word "audit" to describe reserve certification reports. CoinDesk's report makes a clear distinction: These reports are "often misinterpreted as actual audits," but according to McKenna, they are actually a narrower matching exercise. Auditing is to test the company's complete financial statements in accordance with accounting standards. The auditor inspects internal controls and forms opinions. If the company makes mistakes, it may face legal risks. The reserve certification report (at least in the form issued by Mazars) only tests the existence of the disclosed assets at a given time, and the scope is at the exchange's discretion.

This article does not provide the following information

This article cannot provide Crypto.com 's current total reserves, reserve ratios, or the specific date of the most recent Merkel Tree update-no currently dated data is available from the sources reviewed. This article also cannot confirm whether Crypto.com has hired any external accounting or auditing firm since Mazars stopped working in December 2022; none of the four sources mentioned a subsequent successor, which is a gap in the public record rather than a confirmation that there was no such cooperation. As for Coinbase's Deloitte audit, as the source itself emphasizes, it examines financial statements and internal controls-not guarantees of withdrawals, management failures or technical failures, and this article does not describe audited exchanges as safe exchanges. Finally, none of the four sources of information behind this article are original documents: the evidence relied on does not include the Mazars report, the Crypto.com reserve page or Coinbase's 10-K form, but is just news reports about these documents.
