In the wake of FTX’s collapse, trust in centralized crypto custodians has been shaken. Grayscale, the firm behind the massive Grayscale Bitcoin Trust (GBTC), recently stated that while client assets are safe, it will not publicly provide cryptographic proof of reserves due to security concerns.
This article explores Grayscale’s position, the structure of its products, and what this means for investor confidence.
Understanding Grayscale’s Announcement
Grayscale released a statement reassuring investors that the digital assets underlying its products, including GBTC, remain secure and are held in custody by Coinbase Custody. The company emphasized that all holdings are reflected in historical public filings and have been assessed by third-party auditors.
However, in a follow-up tweet, Grayscale clarified a key point:
"Due to security concerns, we do not make such on-chain wallet information and confirmation information publicly available through a cryptographic Proof-of-Reserve, or other advanced cryptographic accounting procedure."
This means that, unlike some exchanges and platforms now rushing to provide transparency, Grayscale will not offer a real-time, verifiable on-chain audit of its holdings.
The Structure Designed to Protect Assets
A crucial part of Grayscale's argument is its corporate structure. Each of its digital asset products is set up as a separate legal entity. Single-asset products are established as statutory trusts, while diversified products are structured as limited liability companies (LLCs).
This separation is intended to ring-fence assets. The trust or LLC agreements governing these products, combined with the custody agreement with Coinbase Custody, explicitly prohibit the lending, borrowing, re-pledging, or otherwise encumbering of the underlying digital assets.
Grayscale asserts that no other entity—not its parent company Digital Currency Group (DCG), not its affiliate Genesis, nor any other related party—has control over these assets.
The Context: FTX and the Demand for Proof
The demand for proof of reserves erupted directly from the fallout of the FTX collapse. Allegations of misappropriated customer funds led to a crisis of confidence across the entire cryptocurrency industry. In response, many major exchanges publicly committed to providing proof-of-reserve audits to verify that user assets are fully backed.
Grayscale’s refusal to participate in this trend, while citing security, has disappointed some in the community who see transparency as the only path to restoring trust.

Grayscale’s Reported Holdings
Despite not providing a live cryptographic proof, Grayscale did disclose the holdings of its products as custodied by Coinbase. According to their tweet:
- Grayscale Bitcoin Trust (GBTC): 635,235 BTC
- As of November 18, 2022, each share of GBTC represented approximately 0.00091502 BTC.
This disclosure, while helpful, is a snapshot rather than the continuously verifiable proof that modern cryptographic techniques can provide.
Frequently Asked Questions
Q: Why won’t Grayscale provide a proof of reserve?
A: Grayscale cites security concerns as the primary reason. Publicly revealing the exact on-chain wallets could, in their view, make them a target for malicious actors and compromise the sophisticated security measures they have in place.
Q: How can I be sure Grayscale isn’t misusing assets like FTX did?
A: Grayscale emphasizes its legal structure. Each trust is a separate entity with binding agreements that prohibit the lending or re-hypothecation of its bitcoin. Furthermore, a third-party custodian, Coinbase Custody, holds the actual assets, adding another layer of separation.
Q: What is the difference between a financial audit and a proof-of-reserve?
A: A traditional financial audit verifies financial statements and practices over a period of time. A cryptographic proof-of-reserve is a near-real-time verification that the custodian holds the assets they claim to hold on-chain, often using Merkle tree proofs to allow individual users to verify their funds are included.
Q: Does Grayscale’s parent company, DCG, have access to these funds?
A: According to Grayscale’s announcement, no. They state that neither DCG, Genesis, nor any other affiliate has control over the digital assets held in their products. The assets are solely under the purview of the individual trusts and their custodian.
Q: What was the market rumor concerning Genesis and Grayscale?
A: A rumor suggested that Genesis, a crypto lending affiliate of DCG, faced a liquidity crisis. It was speculated that DCG might dissolve Grayscale's GBTC and ETHE products to cover Genesis's losses. Grayscale's announcements appear to be, in part, a response to these rumors.
Q: What is the significance of GBTC trading at a discount?
A: GBTC often trades at a discount to its Net Asset Value (NAV), meaning the market price of one share is less than the value of the bitcoin it represents. This can be due to factors like limited redemption mechanisms and market sentiment. A widening discount can sometimes signal investor concern.
The Balance Between Security and Transparency
Grayscale’s position highlights a central tension in the crypto custody space: the balance between operational security and public transparency. While the community demands verifiable proof to prevent another FTX-like disaster, institutions like Grayscale argue that certain security protocols are paramount and cannot be compromised for public scrutiny.
Their stance is that their long-established, multi-layered security and legal structures are a more robust form of protection than a public cryptographic snapshot. For some investors, this is a sufficient guarantee. For others, in a post-FTX world, only visible, verifiable on-chain proof will do.

The path forward for large institutional holders like Grayscale will likely involve navigating these increased expectations for transparency while maintaining the security that has protected assets thus far.
