Binance and Kucoin PoRs were deleted by Mazar

After the collapse of cryptocurrency exchange FTX in November, Mazars, which has its headquarters in Paris, has been leading the rush of the sector to undertake so-called proof-of-reserves reports for exchanges like Binance and other significant ones.

The accounting firm assessed Binance’s proof-of-reserves position and discovered that its bitcoin holdings were overcollateralized. The report’s online URL is no longer active.

Additionally, the auditor discovered that Kucoin’s reserves of BTC, ETH, USDT, and USDC were all overcollateralized. This report is no longer accessible as well. According to Mazar,’s reserves are entirely backed by 1:1.

Other auditors also terminate crypto services

Binance also stressed the significance of having these proof-of-reserves reports examined by impartial auditors:

“We have gone out to several big firms, including the Big Four, who are now unwilling to conduct a PoR for a private crypto company, and we are still looking for a firm who will do so.”

An official comment by Binance

In fact, Mazars is one of many accounting companies to stop working with cryptocurrency companies. On Thursday, Armanino, a longtime partner in crypto accounting, announced the termination of its crypto audit services.
