Coinbase CEO Fires Back At Justin Sun’s Allegations On cbBTC Transparency

As a seasoned analyst with years of experience in the cryptocurrency market, I find myself often caught between the fervor of innovation and the necessity for transparency. In this case, I find Brian Armstrong’s response to Justin Sun’s criticisms of Coinbase’s cbBTC product to be both measured and informative.


As a researcher, I’ve recently found myself addressing remarks from Justin Sun, the founder of Tron, regarding our newly launched wrapped Bitcoin product, cbBTC. In response to his concerns, voiced on his social media platform X, it was only two days ago that we introduced this innovative solution on the Binance Smart Chain network.

Coinbase CEO Slashes All Allegations

In a straightforward reply, Armstrong downplayed Sun’s worries as mostly unnecessary. He explained that every exchange-traded fund (ETF) transaction, including minting and burning, is completed on the blockchain. ” frankly, I’m not sure what the fuss is about. All ETF mints and burns we handle are eventually settled on the blockchain,” Armstrong stated. He further noted that institutional clients can take advantage of trade financing and over-the-counter (OTC) options before their trades are finalized on the blockchain.

The CEO of Coinbase additionally highlighted that the wrapped Bitcoin (cbBTC) functions as a product held by a centralized custodian, which has always been disclosed. To clarify, with cbBTC, you are indeed placing trust in a centralized custodian to hold the original Bitcoin; this point has never been disputed by us.

Through his posts, Tron’s Sun voiced several apprehensions about Coinbase’s latest product. Particularly, he emphasized the absence of Proof-of-Reserve (PoR) and audits for cbBTC, labeling it as a system that relies on trust without verification. Furthermore, he cautioned users that their balances might be frozen at any time without prior notification.

As per Sun’s assessment, the wrapped Bitcoin offered by Coinbase carries a substantial risk of government intervention. In simpler terms, if a U.S. government subpoena is issued, it could potentially seize all your Bitcoins. This form of Bitcoin closely mirrors central bank control over traditional currencies, which is a concerning development for Bitcoin supporters. Sun expressed his concerns, stating that this situation marks a grim day for Bitcoin.

Sun’s worries found echoes among some of his supporters on X, several of whom sided with his perspectives. Yet, the CEO of Coinbase has countered that their operations adhere to common industry practices. Armstrong allayed concerns by stating that the company undergoes regular audits by Deloitte and, being a publicly traded entity, it prioritizes transparency.

According to Armstrong, our company undergoes an annual audit by Deloitte since we’re publicly traded. Furthermore, he emphasized that the safety of institutional clients’ funds is guaranteed when they’re stored in Coinbase’s secure vault system.

The Need For Proof-of-Reserve

With the continuous controversy surrounding it, Proof-of-Reserve has emerged as a significant topic of conversation. After the high-profile failures of Terra/LUNA and FTX in 2022, Proof-of-Reserve reports are now viewed as essential for verifying a cryptocurrency exchange’s transparency and financial stability.

Multiple prominent cryptocurrency platforms, including Binance, frequently publish Proof-of-Reserves (PoR) reports to assure users about their digital assets. For example, Binance recently disclosed its 22nd PoR report. This document showed that the exchange’s Bitcoin holdings relative to user balances amounted to a ratio of 106.84%.

Therefore, the importance of Proof-of-Reserve (PoR) reporting is particularly significant given the increasing user expectations for transparency in centralized exchanges (CEXs). However, despite Sun’s criticisms, Armstrong’s response underscores Coinbase’s persistent dedication to adhering to top-tier practices for its institutional clients and services like cbBTC.
