Binance Audited by Mazars, Confirms Bitcoin Reserves are Fully Collateralized

Binance BTC Reserves are Fully Backed

Mazars, an international audit, tax and advisory firm, has confirmed that Binance has more than enough Bitcoin (BTC) to cover all customer deposits. The report verified a 101% collateralization ratio on 575,742 BTC in net customer deposits as first published on their proof-of-reserves system on November 25. All assets included customers’ spot, options, margin, futures, funding, loan and earn accounts for BTC and wrapped BTC circulating on the Bitcoin, Ethereum, BNB Chain and BSC blockchains.

To ensure customers’ assets are not being lent out or stolen without permission, Binance implemented a Merkle Tree proof-of-reserves system that allows customers to independently verify the safety of their assets.

Binance Securely Controls Custodial Wallets

Mazars has also asked Binance to perform transactions at specific times to prove that the wallets were actually under Binance’s control. This clarifies the situation in late November when Binance moved 127,351 BTC to an unknown wallet. According to the report, Mazars used Etherscan and BSCscan to check that the wallets indeed belong to Binance.

Moreover, Mazars reviewed the scripts that Binance uses to extract the total net deposits, making sure there was no duplicated or rigged user IDs. This confirms that Binance’s Merkle tree is built with open source script developed by Silver Sixpence.

What This Means for Investors

Binance is the world’s largest crypto exchange by trading volume, and is arguably the most used platform for all crypto users. After the collapse of FTX, Binance CEO Changpeng Zhao (CZ) was jokingly hailed as the “savior” of crypto, doing everything he can to repair the industry. However, Binance itself is no exception to scrutiny as a result of FTX’s collapse. People need to know what centralized exchanges are doing with their money.

Binance’s audit has cleared up a lot of doubt, restoring confidence in the exchange. However, there are still two issues raised by the crypto community:

  • Is Mazars a reliable auditing firm?

While most of the community praises Binance’s initiative, several Crypto Twitter users expressed concerns that Mazars is not one of the “Big Four” accounting firms: Deloitte, Ernst & Young (EY), PricewaterhouseCoopers (PwC), and KPMG. For the longest time, audits made by any one of the Big Four is the gold standard, and any other firms are deemed not “credible” enough.

This is reasonable enough seeing as FTX was in fact audited by smaller accounting firms. But that might not be the case for Mazars. Founded in 1945, Mazars is one of Europe’s largest audit and accounting firms with global presence. In fact, Mazars was a longtime accountacy firm for former president Donald Trump. But after finding out Trump’s business filings were not adding up, Mazars cut ties with his business. Given their track record, it is safe to say that Mazars is reliable as they conduct due diligence on any business.

  • Binance audit only accounts for BTC reserves

The audit only focuses on BTC assets for now. As of now, Binance does not have a proof-of-reserves system for other cryptocurrencies. But at the end of the day, this is a big step towards a more transparent ecosystem. Let’s hope there will be more developments in the coming weeks.
