Catenaa, Sunday, August 23, 2026- Crypto exchange MEXC reported reserve ratios above 100% for Bitcoin, Ether, USDT and USDC in its August proof-of-reserves snapshot, with Bitcoin coverage reaching 288% as exchanges face continuing pressure to demonstrate custody transparency.
MEXC said its latest report covered 4,282.20 BTC in customer balances and showed a Bitcoin reserve ratio of 288%.
USDT reserves were reported at 115% against about 1.69 billion USDT in customer holdings.
USDC recorded a reserve ratio of 114%, covering about 171 million USDC in customer balances.
Ether reserves stood at 113% against 58,457.33 ETH held for customers.
A reserve ratio above 100% means the assets included in the proof-of-reserves calculation exceeded the corresponding customer balances recorded in the snapshot.
MEXC said the August report was independently reviewed by blockchain security company Hacken.
The 288% Bitcoin ratio is substantially higher than the reported coverage for the exchange’s other major assets.
At that ratio, MEXC reports considerably more Bitcoin reserves than the BTC customer liabilities included in the snapshot.
USDT, USDC and Ether sit much closer to the 100% threshold, though each remained above it.
The distinction matters because proof of reserves is intended to answer a relatively narrow question: whether an exchange can demonstrate control over enough specified assets to cover specified customer balances at a particular point in time.
That became a major industry concern following the collapse of FTX in 2022, when customers discovered that apparent account balances did not necessarily correspond with readily available assets.
Major centralized exchanges subsequently expanded onchain reserve disclosures, Merkle-tree verification and third-party assessments.
Proof-of-reserves systems typically combine two sets of information.
The first attempts to demonstrate that an exchange controls crypto assets held at identifiable blockchain addresses.
The second compares those reserves with customer balances, often using a cryptographic Merkle-tree structure that allows individual users to verify whether their balance was included without revealing every customer account.
MEXC allows users to perform that type of verification through its reserve platform.
The August figures therefore offer customers a way to assess whether major crypto assets included in the exercise were covered at the time of the snapshot.
MEXC says it intends to continue issuing proof-of-reserves disclosures monthly.
A proof-of-reserves ratio should not be confused with a complete financial statement audit.
That limitation is especially important when an exchange advertises reserve coverage considerably above 100%.
The U.S. Public Company Accounting Oversight Board has previously warned that proof-of-reserves reports can be limited in scope and should not automatically be treated as evidence that a crypto company is solvent.
A reserve snapshot may not give investors a complete view of all corporate liabilities, loans, contingent obligations, related-party transactions or assets outside the scope of the exercise.
Different providers can also use different methodologies.
MEXC itself acknowledges in educational material explaining its August figures that a high reserve ratio does not mean an exchange carries zero risk.
The more precise interpretation of the latest disclosure is therefore that MEXC reports reserves above customer balances for the major assets covered by its proof-of-reserves methodology.
It is not proof that every aspect of the exchange’s wider financial position has been audited.
MEXC also points to separate financial buffers designed for other types of customer risk.
The company says its Futures Insurance Fund has reached about 751 million USDT.
Such funds are designed primarily to deal with losses arising from futures liquidations and extreme market conditions rather than serve as ordinary backing for customer spot balances.
MEXC also operates what it calls a Guardian Fund.
The company has said it plans to expand that reserve structure from $100 million to $500 million over the next two years.
These mechanisms serve different purposes from proof of reserves and should not be combined when assessing reserve coverage.
Reserve disclosures have become part of competition among centralized cryptocurrency exchanges.
Price, token selection and trading fees remain important, but users increasingly evaluate how exchanges custody assets and whether reserve information can be independently checked.
Blockchain technology gives crypto exchanges one advantage conventional financial institutions do not usually have.
Assets held at published blockchain addresses can be observed continuously.
That makes it possible for customers and analytics firms to verify whether specified coins remain at wallets controlled by an exchange.
The harder part remains proving that the liability side is complete.
An exchange can publicly demonstrate control over billions of dollars in cryptocurrency, but users still need confidence that all relevant customer claims and corporate obligations have been accounted for.
That is why proof of reserves and audited financial statements answer different questions.
Catenaa View
MEXC’s 288% Bitcoin reserve ratio makes an eye-catching headline, but the more useful story is the continuing evolution of exchange transparency after FTX.
A ratio above 100% is preferable to a disclosed shortfall.
A ratio of 288% indicates a large reported cushion for Bitcoin under the methodology being used.
But reserve ratios should not become another league table where the highest percentage is automatically interpreted as the safest exchange.
The quality of the underlying verification matters.
Users need to know which wallets are included, which liabilities are counted, when the snapshot was taken and whether the process has been independently examined.
They also need to distinguish reserves from solvency.
A solvent exchange needs enough assets to meet its total obligations, not merely proof that selected cryptocurrencies exceed selected customer balances at one moment.
That does not diminish the usefulness of proof of reserves.
It defines what the tool can reasonably establish.
Monthly disclosures, onchain wallet verification and customer-level Merkle proofs can reduce opacity and make it harder for an exchange to conceal a straightforward reserve deficit.
They work best as one layer of financial transparency rather than a replacement for broader financial reporting.
For MEXC, maintaining ratios above 100% month after month will therefore be more informative than any single unusually high reading.
Proof of reserves became a widely used crypto exchange transparency mechanism after the 2022 failure of FTX intensified scrutiny of how centralized platforms hold customer assets. MEXC publishes reserve information covering major cryptocurrencies and allows customers to verify account inclusion through cryptographic tools. The exchange said its August 2026 report showed Bitcoin, Ether, USDT and USDC reserve ratios above 100%. It also maintains separate futures and protection funds designed for risks outside ordinary spot-asset reserve coverage. Proof of reserves remains distinct from a full audit of an exchange’s financial statements and total liabilities.
