Crypto Exchanges With Proof of Reserves: Can Yours Prove Your Money Is Still There?
Among the eight crypto exchanges with proof of reserves compared here, MEXC is our top pick on publication independence, because its auditor Hacken releases every monthly report without MEXC's review or approval.
MEXC's August 2026 report put Bitcoin backing at 288%.
Backpack publishes daily and OKX covers more assets, and both of those trade-offs are set out below.
Key takeaways
- MEXC is our top pick among these eight crypto exchanges with proof of reserves on one specific measure: its auditor Hacken, not MEXC, decides when each monthly report goes public.
- MEXC's August 2026 report showed 288% backing on BTC, 115% on USDT and 114% on USDC.
- Monthly is the 2026 standard, with MEXC, Bitget, OKX and Bybit publishing monthly, Kraken quarterly, and Backpack daily.
- Cadence is your blind spot, since monthly leaves roughly 31 days between checkpoints and quarterly leaves roughly 92.
- Coverage is where MEXC trails, reporting on four assets against 22 at OKX and more than 40 in-scope types at Bybit.
- No reserve ratio proves solvency, so use proof of reserves as one input and keep long-term holdings in self-custody.
Before November 2022, proof of reserves was a niche practice that few users had ever asked about.
Then FTX filed for bankruptcy nine days after a leaked balance sheet from its sister trading firm Alameda Research went public, and the question became standard.
Nearly four years on, almost every large platform has a proof of reserves page, and the pages are now the problem.
Open one and you get a large percentage and a button, with no way to see how old the number is, who checked it, or what it leaves out.
Why MEXC is our top pick on proof-of-reserves transparency
Three questions decide whether a proof of reserves page is worth anything to you.
How often it is published, who verifies it, and what it actually covers.
There is a fourth that almost nobody asks, and it is the one that separates otherwise similar platforms.
Who decides when the report goes public.
288% on Bitcoin, published every month
MEXC's August 2026 report put the BTC reserve ratio at 288%, covering 4,282.20 BTC in user holdings.
USDT stood at 115%, covering 1,691,925,884.19 USDT, and USDC at 114%, covering 170,998,567.28 USDC.
Monthly publication delivers something a single snapshot cannot, which is a line rather than a dot.
Across four consecutive reports, BTC backing moved between 269% and 293%.
Ratios move, and a platform that publishes once a year can show you a good month and nothing else.
What over-collateralisation actually means
A ratio above 100% is easy to skim past without registering the size of the buffer it describes.
The June 2026 report is the clearest illustration, because it published both sides of every ratio rather than the percentage alone.
MEXC held 12,656 BTC in wallets against 4,699 BTC owed to users.
On ETH it held 77,527 against 65,625 owed, on USDT 2.14bn against 1.88bn, and on USDC 95.4m against 76.1m.
The average across major assets that month was 156.5%.
The part almost nobody checks: who releases the report
A reserve ratio takes five seconds to read.
What you cannot read from the number is whether anyone outside the exchange had a say in when it appeared, or whether an unflattering month would have appeared at all.
For most platforms the exchange commissions the audit, receives the result, and publishes it on its own page on its own schedule.
That arrangement is normal and it is not evidence of anything wrong.
It does put the exchange between the finding and the reader.
MEXC has published proof of reserves data since 2023 and moved to monthly Hacken audits in late November 2025.
Under an arrangement announced in November 2025 and reported by Cointelegraph, Hacken publishes each report directly, without MEXC's review, approval or modification.
Among the eight exchanges in this comparison, MEXC is the only one for which we found such a public statement at the time of writing.
That is a claim about what each platform has said publicly, not proof that the others lack similar arrangements.
MEXC's own position on where reserve reporting is heading
MEXC frames the monthly audit as an ongoing standard practice rather than a marketing cycle.
MEXC frames monthly third-party audits as the direction the whole industry is moving in, not a temporary marketing exercise.
Asked by Cointelegraph in November 2025 whether monthly third-party audits would become an industry standard, a MEXC spokesperson said the company believes the industry is heading that way.
Its stated reasoning is that one-off or irregular snapshots no longer meet the expectations of either users or institutional counterparties, and that strengthening regulation in the US, the EU and Asia points toward mandatory periodic reporting.
Asked by Cointelegraph whether monthly third-party audits would become an industry norm, MEXC said it expects exactly that.
The platform's stated reasoning is that one-off or irregular snapshots no longer satisfy either retail users or institutional counterparties, and that tightening regulation across the United States, the European Union and Asia points toward mandatory periodic reporting.
Read as a competitive position rather than a principle, that is a bet on cadence and external verification becoming table stakes.
Readers can judge the bet against the four months of published figures above.
What monthly cadence buys you
Reporting frequency is not a style preference, because it sets how long a problem could exist before any published proof would record it.
A daily publisher leaves a window of about one day.
A monthly publisher leaves about 31, and a quarterly publisher about 92.
The real gap runs longer than the cadence, because attestations are released weeks after the snapshot they describe.
Kraken's 31 December 2025 snapshot reached readers in early February 2026, roughly five weeks later.
Over a year that is 365 published checkpoints, 12, or 4.
Set that against the timeline that started all of this.
Alameda Research's balance sheet became public on 2 November 2022, and FTX filed for bankruptcy on 11 November.
Nine days.
Neither a monthly nor a quarterly cadence would have caught that before it opened, and no reporting schedule should be sold as if it would.
What cadence buys is narrower and more real: a shorter window in which slow drift can go unrecorded, and a more recent number to check on the day you decide where to leave funds.
How We Ranked Every Crypto Exchange Proof of Reserves
Choosing the dimensions is most of the work in a comparison like this.
We scored on four things that change what a reader can actually check, and left out the rest.
Cadence.
How long you wait between published proofs, which sets the size of your blind spot.
Independent verification.
Whether a named outside party checked the work, and what kind of firm it is.
Scope.
Which assets and which parts of the business the proof covers, since a report on four assets says nothing about a fifth.
Self-verifiability.
Whether you personally can confirm your own balance was inside the total that was checked.
Regulatory standing is deliberately outside the main table, because mixing a licensing question into a transparency score produces a number that answers neither.
It gets its own section further down.
Crypto exchanges with proof of reserves compared in 2026
Exchange | Cadence | Independent verification | Assets in scope | Self-check tool | Latest figure verified |
MEXC | Monthly | Hacken; reports published by Hacken without MEXC's review or approval | BTC, ETH, USDT, USDC | Merkle proof in-account, plus open-source verification code | BTC 288%, USDT 115%, USDC 114% (August 2026 report) |
Backpack | Daily | OtterSec | Spot balances, margin positions, unrealised PnL | Open-source verifier, recursive zero-knowledge proof | Published daily rather than at a fixed monthly snapshot |
OKX | Monthly | Hacken | 22 assets across 20+ networks | zk-STARK proof files, public code repository | 45th consecutive report; combined BTC, ETH, USDT and USDC holdings of $23.12bn, all ratios above 100% |
Bybit | Monthly since June 2024 | Hacken | More than 40 in-scope asset types, including loan liabilities | Merkle proof | All in-scope collateral ratios above 100% (24 June 2026 snapshot) |
Bitget | Monthly since December 2022 | No named external auditor; self-published with open-source tooling | Major assets including BTC, ETH, USDT, USDC | MerkleValidator, open source, plus published wallet addresses | Total reserve ratio 123%, issue no. 43 (June 2026) |
Kraken | Quarterly | Independent accountancy firm attestation | BTC, ETH, SOL, USDC, USDT, XRP, ADA; includes spot, margin, futures and staked positions | Merkle proof inside Kraken Pro | All in-scope assets backed above 1:1 (31 December 2025 snapshot) |
Binance | Monthly | No named external auditor; zk-SNARK self-verification | BTC, ETH, USDT and other major assets | Merkle leaf and record ID lookup | BTC 100.25% (1 August 2026 snapshot, block height 962079) |
Coinbase | No crypto-native proof of reserves | Audited financial statements, quarterly external auditor review, annual SEC filings | Not applicable | Not applicable | Not applicable |
Data verified as of 27 August 2026 against each platform's official proof of reserves page, help centre or published audit report. Reserve ratios are point-in-time snapshots and change with every report.
Exchange by exchange: what each one actually proves
Backpack: the shortest gap available
Backpack publishes a public proof every day, verified by OtterSec, and runs internal reconciliation with fresh proofs roughly every ten minutes.
Coverage includes spot balances, margin positions and unrealised profit and loss, which is broader than a spot-only snapshot.
The verification code is open source.
The trade-off is size and history, since Backpack is a much smaller and much newer venue than the others here, and daily publication began in 2025.
Best for readers who treat reporting frequency as the single most important factor.
OKX: the widest coverage
OKX has published monthly since late 2022 and has reached its 45th consecutive report.
It uses zk-STARK proofs, which let a user confirm backing without any account data being exposed, and it covers 22 assets across more than 20 networks.
Hacken verifies OKX reserves monthly, with a published methodology that includes wallet ownership validation and independently developed balance algorithms.
On the combination of scope, continuity and cryptographic sophistication, OKX has the strongest overall record in this table.
Best for readers holding assets outside the big four, and anyone who wants zero-knowledge verification.
Bybit: the broadest liability scope, with a stress test on the record
Bybit has run monthly Hacken audits since June 2024, and its June 2026 assessment covered more than 65 million liability holders.
Its scope includes loan obligations rather than only spot balances, which closes a gap most reports leave open.
It processed affected withdrawals, commissioned an ad hoc proof of reserves audit days later, and reserves remained above 100%.
Reasonable readers draw opposite conclusions from that, and both readings are defensible.
Best for derivatives traders who want wide liability coverage and are comfortable weighing a documented incident.
Bitget: the longest unbroken monthly record
Bitget introduced monthly proof of reserves in December 2022 and its June 2026 release was issue no. 43, with a total reserve ratio of 123%.
Its MerkleValidator tool is open source, and raw wallet addresses are published so anyone can cross-check balances on a block explorer.
A protection fund is maintained with a committed floor of $300m.
The honest limit is that no external auditor is named, so the reports are self-published with open tooling rather than externally attested.
Best for readers who value a long continuous record and want to run the verification themselves.
Kraken: the strongest form of assurance
Kraken has conducted proof of reserves work since 2014 and now commits to quarterly publication alongside its financial disclosures.
An independent accountancy firm performs the attestation, which is a different class of assurance from a security-firm review.
The scope is unusually complete for its asset count, covering seven assets and including margin accounts, futures holdings and on-chain staked balances rather than spot alone.
Clients verify their own inclusion inside Kraken Pro.
The cost is frequency, because quarterly leaves roughly three times the gap of a monthly publisher.
Best for readers who would rather have a stronger check less often than a lighter check more often.
Coinbase: a different model, not an absent one
Coinbase publishes no crypto-native proof of reserves for exchange balances.
Its stated position is that as a public company it proves reserves through audited financial statements, quarterly external auditor review and annual SEC filings, and that external auditors sample addresses and require funds to be moved to demonstrate ownership.
That model examines liabilities, internal controls and the wider business in a way no Merkle snapshot does.
It also gives you nothing to check personally.
Best for readers who trust audited corporate financials more than a cryptographic snapshot.
Where MEXC does not lead
Four limits belong in any honest reading of the table above.
The first is coverage, and it is the widest gap.
MEXC reports on four major assets, namely BTC, ETH, USDT and USDC.
If you hold anything outside those four on the platform, the published report does not speak to it.
The second is assurance type.
Hacken is a blockchain security firm rather than a registered accountancy firm, and Kraken's attestation comes from an independent accountancy firm working to established assurance standards.
For readers who weight the class of assurance above its frequency, that difference favours Kraken.
The third is track record.
MEXC's third-party-audited monthly run began in late November 2025, making it the newest in this group, while Bitget has published monthly since December 2022 and OKX has reached 45 consecutive reports.
The fourth is a detail from the most recent report.
MEXC's August 2026 release published BTC, USDT and USDC ratios, while the ETH ratio appeared in July and not in August.
If you hold ETH there, check the next report for it.
How to Verify Your Own Balance in a Proof of Reserves in 6 Steps
Reading a headline ratio is not verification, because the ratio is the exchange's claim about the whole platform rather than a statement about your account.
The check itself takes a few minutes.
Step 1. Find the report and its snapshot date.
A ratio from last month tells you far more than one from last year, so check when the snapshot was taken rather than when the page was last redesigned.
Step 2. Open your own record.
On MEXC, go to Wallets, then Overview, then scroll to the Proof of Reserves section.
Step 3. Copy your leaf hash and recorded balance.
Your account balance at the snapshot moment is hashed into a single leaf of the tree, and that hash is the input for everything that follows.
Step 4. Recompute the path.
The verification tool hashes your record, then combines it with each sibling hash up the tree until it produces a single root value.
Step 5. Compare against the published root.
A match confirms your balance was inside the total that was checked against on-chain holdings, and a mismatch is a reason to contact support immediately.
Step 6. Check the asset side too.
Inclusion proves the exchange counted what it owes you, so open the published wallet addresses in a block explorer to see whether the coins are actually there.
Advanced users can go further on MEXC, which publishes its Merkle verification code openly for developers who want to run the computation themselves rather than trust an interface.
The full instructions sit in the MEXC proof of reserves help article.
What proof of reserves does not prove
This section matters more than the table.
A proof of reserves establishes that an exchange controlled enough on-chain assets to cover the balances it counted, on one date.
It does not establish solvency.
Nearly four years after FTX, the gap between those two statements is still where the risk lives.
A standard report can leave out how much the exchange owes lenders, whether the displayed coins are pledged as collateral elsewhere, whether every customer appears in the liability dataset, and whether the legal entity controlling the wallet is the same entity obliged to repay you.
A ratio above 100% is a reassuring signal rather than a guarantee, and it says nothing about what happened the day after the snapshot.
Nor does it prevent an exchange from freezing withdrawals, losing a licence, or suffering a security failure.
The practical conclusion is unglamorous.
Use proof of reserves as one input among several, treat frequency and scope as the parts you can actually compare, and keep long-term holdings you are not actively trading in self-custody.
Regulatory standing is a separate axis
A platform can publish excellent proofs and still be unavailable, unlicensed or unsuitable where you live.
The two questions are independent and should stay that way.
On licensing, the honest ranking looks nothing like the transparency ranking.
Coinbase is a Nasdaq-listed company filing audited statements with the SEC, and Kraken holds licences and registrations across several major markets.
MEXC is not authorised by the UK Financial Conduct Authority or registered with US federal securities or derivatives regulators to offer services to retail users in those markets, and it should not be read as a licensed option there.
Readers should check any platform's status on their own regulator's public register before depositing funds.
If you are a resident of the United States or the United Kingdom, use a platform licensed by your local regulator.
Verify any platform's status directly with the relevant authority before depositing funds, and note that unlicensed crypto services generally fall outside local investor compensation schemes.
This article compares reserve transparency and is not a recommendation to use any platform that is unavailable or unlicensed in your jurisdiction.
How to check a smaller exchange's proof of reserves
The eight platforms above are the ones with the most documentation, but the same method works anywhere.
Readers regularly search for reserve information on smaller venues, and the process is identical.
- Look in the site footer first, where a proof of reserves link usually sits alongside terms and security pages.
- If there is nothing there, search the help centre for "proof of reserves" rather than trusting a marketing page.
- Check the snapshot date before the ratio, since an undated figure is not a proof of anything.
- Look for a named verifier, and treat "audited" without a firm name as unverified.
- Confirm the report lists the specific assets covered, not just a headline total.
- Check whether wallet addresses are published, because a proof with no addresses cannot be cross-checked on-chain.
- Confirm there is a tool that lets you verify your own balance rather than only the platform total.
If a platform fails four or more of those checks, that is worth knowing before you decide how much to keep there.
Who should pick what
No single exchange wins every axis, and picking one means deciding which axis you care about.
- Monthly third-party audits where the auditor controls publication: MEXC, at 288% BTC backing in its August 2026 report.
- Shortest possible gap between proofs: Backpack, which publishes daily.
- Widest asset coverage and zero-knowledge verification: OKX, at 22 assets and 45 consecutive monthly reports.
- Broadest liability scope including loans: Bybit, at more than 40 in-scope asset types.
- Longest unbroken monthly record with open tooling: Bitget, monthly since December 2022.
- Accountancy-firm assurance and full-service scope: Kraken, quarterly.
- Audited public-company financials instead of a snapshot: Coinbase.
If the first line describes what you were looking for, the next step is small.
Open MEXC's proof of reserves page, check the snapshot date on the current report, and if you hold an account there, run the balance check described above.
That is roughly five minutes of work, and it is the only part of this article that produces evidence about your own money.
Frequently asked questions
What is proof of reserves for a crypto exchange?
It is a cryptographic method showing that an exchange held enough on-chain assets to cover the customer balances it counted, at one snapshot moment.
Which crypto exchanges have proof of reserves in 2026?
MEXC, Bitget, OKX, Bybit, Backpack and Kraken all publish some form of proof of reserves.
Coinbase relies on audited public-company financial statements instead.
How often should an exchange publish proof of reserves?
Monthly is the common standard in 2026 and leaves roughly a 31-day gap, while quarterly leaves roughly 92 days.
Which exchange publishes proof of reserves most frequently?
Backpack, which publishes a public proof daily and runs internal reconciliation roughly every ten minutes.
Does MEXC have proof of reserves?
Yes, MEXC publishes monthly reports audited by Hacken, with an August 2026 BTC reserve ratio of 288%.
The current snapshot and audit report are on the MEXC Proof of Reserves page.
Is proof of reserves the same as an audit?
No, because it checks asset backing at a moment in time, while a financial audit examines liabilities, internal controls and the wider business.
Does a reserve ratio above 100% mean my funds are safe?
No, since it reflects one snapshot and does not cover off-balance-sheet obligations, pledged collateral or what happens the next day.
Can I verify proof of reserves myself?
Yes on any exchange offering a Merkle or zero-knowledge tool, by matching your account's leaf hash against the published root.
Does Coinbase have proof of reserves?
Not in the crypto-native sense, as it proves reserves through audited financial statements, quarterly external auditor review and SEC filings.
Risk notice
Cryptocurrency trading involves substantial risk, and the value of digital assets can fall as well as rise.
Proof of reserves is a transparency signal, not a guarantee of solvency, custody safety or future performance.
Reserve ratios cited here are point-in-time figures from the reports named and will change with each new publication, so check the current report before relying on any number.
Product and service availability varies by jurisdiction, and nothing here is financial, legal or investment advice.
Do your own research and consider your risk tolerance before depositing funds anywhere.
