MEXC’s September 2026 Proof of Reserves Reaffirms Full Backing of User Assets, BTC Reserve Ratio Increases to 297%

Monthly Audit Shows Exchange Holds Nearly Three Times Its Bitcoin Obligations

MEXC released its September 2026 Proof of Reserves report on September 15, with auditor Hacken confirming that every major asset category on the platform is backed at a ratio exceeding 1:1. The headline figure is a BTC reserve ratio of 297% – meaning the exchange holds 12,202.13 BTC against 4,106.57 BTC in user balances – up from 288% the previous month. The snapshot was taken on September 10, 2026, and covers four primary assets: BTC, USDT, USDC, and ETH.

For an industry still rebuilding credibility after a string of high-profile exchange collapses, monthly third-party audits with independently verifiable data carry more weight than internal assurances ever could.

MEXC, founded in 2018 and operating across more than 170 markets, has been publishing reserve data on a monthly cadence. The exchange markets itself as a zero-fee trading platform and has positioned the Proof of Reserves program as an ongoing infrastructure commitment rather than a one-time disclosure. Each audit covers Proof of Liabilities, Proof of Ownership, Reserves Calculation, and a full PoR Assessment – four distinct verification categories that Hacken evaluated in this cycle.

What the Numbers Actually Show

The September audit breaks down as follows across all disclosed assets. USDT reserves stand at 1,818,202,910.24 USDT against user holdings of 1,526,526,878.38 USDT, a 119% coverage ratio. USDC comes in at 111%, with 299,925,929.77 USDC in reserves covering 269,894,125.25 USDC in user balances. ETH mirrors that same 111% figure, with 58,917.60 ETH held against 53,243.98 ETH in user accounts. All four assets exceed the 1:1 minimum threshold that Hacken confirmed as the audit benchmark.

The verification method relies on Merkle Tree technology, which allows individual users to confirm their specific balance is included in the total reserve calculation without exposing the account data of other users on the platform. This structure is increasingly standard among exchanges that take reserve transparency seriously, and it addresses a core limitation of earlier reserve disclosure formats that showed aggregate totals without any user-level verification layer.

Vugar Usi, CEO of MEXC, described the monthly publishing schedule as a deliberate accountability mechanism. “Protecting user assets and earning their trust are fundamental responsibilities, not optional commitments,” Usi said. “In an industry where confidence has been tested time and again, transparency must be demonstrated through actions that users can independently verify. That is why we publish verifiable Proof of Reserves every month, giving users the ability to validate their asset data at any time rather than simply relying on our assurances.”

Two Separate Safety Funds Sit Alongside the Reserve Data

Beyond the core reserve ratios, MEXC maintains two distinct financial buffers that operate independently of the monthly audit figures. The first is the Futures Insurance Fund, designed to absorb losses that occur when liquidations are triggered by extreme market conditions – a scenario that has caused significant user harm on other platforms during sharp price dislocations. As of the time of publication, that fund held approximately 798 million USDT.

The second structure, called the Guardian Fund, uses a dual-reserve approach combining both USDT and BTC holdings. It is intended to provide full compensation coverage for losses attributable to platform-side issues rather than market conditions. The Guardian Fund held $101 million at press time. MEXC has stated it intends to expand that figure to $500 million within two years, though no specific milestone schedule has been disclosed for reaching that target.

The distinction between the two funds matters technically. The Futures Insurance Fund is reactive – it engages when market-driven liquidations create gaps – while the Guardian Fund addresses platform liability, covering scenarios where the exchange itself is the source of a user’s loss. Running both simultaneously means MEXC is attempting to separate market risk from operational risk in its compensation architecture, rather than pooling them under a single undifferentiated reserve. For context on how exchanges are building out their security infrastructure more broadly, MEXC previously blocked $38.6 million in suspect funds as AI-driven attacks on crypto platforms surged, signaling that the reserve program sits within a wider set of defensive measures.

Verification Is Available, Not Just Announced

The full September audit report and reserve snapshot are publicly accessible through MEXC’s dedicated Proof of Reserves page, where users can run their own balance verification using the Merkle Tree tool. MEXC’s BTC ratio has now climbed nine percentage points in a single month – from 288% in August to 297% in September – and the audit cycle shows no sign of breaking from its monthly cadence. Whether the Guardian Fund’s $500 million expansion target arrives on schedule, and what the reserve ratios look like when market conditions eventually turn against the exchange rather than for it, are the questions that will define how durable this transparency framework actually is.
