MEXC Proof of Reserves: What It Proves, and What It Does Not

MEXC publishes a reserves report every month and August 2026's puts Bitcoin at 288%. That is a real thing worth having. It is also narrower than it sounds, and there is one check that makes it mean something for you personally which almost nobody bothers to run.

I spend a lot of this site being unflattering about MEXC's regulatory position, so it is only fair to be equally precise when it does something well. Monthly Proof of Reserves, audited by an outside firm, with cryptographic proofs a user can check themselves, is better practice than a good number of exchanges manage. Here are the August 2026 figures.

A ratio above 100% means MEXC held more of that asset than users had deposited, at the moment the snapshot was taken. Bitcoin at 288%[src] covers 4,282.20 BTC of user holdings; USDT at 115%[src] covers about 1.69 billion USDT. The reports are produced monthly and audited by Hacken.

The one check that actually involves you

The reserves side of this is easy to verify — the wallets are on a public blockchain. The hard side is the liabilities: what users are owed. An exchange that quietly understates what it owes can report any ratio it likes.

This is what the Merkle tree is for. MEXC's system lets you confirm that your balance was included in the total the auditor checked against, without revealing anyone else's. That is the step that turns a press release into evidence, and it is the step nearly nobody performs.

If a reserves report is going to influence whether you keep money on an exchange, run that check yourself once. If your balance is not in the tree, the ratio told you nothing about your money.

What the number does not cover

Four honest limits, none of which are unique to MEXC:

• It is a snapshot. Reserves are measured at a moment. A monthly cadence is good practice, and it still says nothing about the twenty-nine days in between.
• It shows assets, not solvency. Proof of Reserves does not reveal what the company owes elsewhere — loans, obligations to other entities, or whether the reserve assets themselves are pledged as collateral somewhere. A full picture needs proof of liabilities too.
• The auditor is engaged by the exchange. Hacken is a security firm doing a specific attestation, not a statutory auditor and not a regulator. That is a real difference in what the work covers and who it answers to.
• It is not a licence. Reserves say nothing about whether the exchange is authorised where you live, or who you could complain to. On that, eight regulators have published warnings about MEXC, and the Seychelles regulator has stated it cannot help users recover funds.

Why 288% is less strange than it looks

A first reaction to "288%" is that something must be off, because a custodian holding nearly three times what customers deposited is unusual. Two things explain it. Ratios above 100% include the exchange's own holdings sitting in the same wallets, and the user Bitcoin balance being covered is not especially large — 4,282.20 BTC, on a venue CoinGecko ranks ninth by trust score.

Which is worth saying plainly: a high percentage is not automatically a stronger result than a lower one. USDT at 115%[src] against 1.69 billion USDT of user money is the more load-bearing figure in that report, because that is where the money actually is.

How I would weigh it

Proof of Reserves is a genuine positive and I would rather have it than not. It rules out one specific and historically expensive failure — an exchange that has quietly stopped holding what it says it holds. Several collapses would have been caught earlier had this been standard.

What it does not do is replace the thing MEXC does not have, which is authorisation and a supervisor. Those cover different risks. Reserves tell you the assets were there last month. A licence tells you someone can act if they are not there next month.

My own position, for whatever it is worth: I keep on any exchange only what I would be prepared to lose, and a reserves report does not change that number. It does make me less worried about the specific scenario it addresses, which is not nothing.
