One filing amendment. One custodian swap. A whole lot of implications for how Wall Street stores its crypto.
Grayscale Investments amended its Hyperliquid (HYPE) ETF S-1 filing on April 20, replacing Coinbase Custody Trust Company with Anchorage Digital Bank as the designated custodian. The change, first reported by CoinMarketCap and later analyzed by CryptoSlate, represents more than a routine operational swap – it signals a potential restructuring of how institutional crypto products handle custody.
Why Anchorage Over Coinbase
Anchorage Digital Bank holds a distinction that no other crypto-native firm can claim: it’s the first and only federally chartered digital asset bank in the United States, authorized by the Office of the Comptroller of the Currency (OCC).
That federal charter matters for ETF filings. The SEC has historically scrutinized custody arrangements in crypto ETF applications, and a custodian operating under a federal banking charter provides a regulatory system that state-level trust company licenses don’t. Coinbase Custody operates as a New York-chartered trust company, which carries significant oversight but stops short of the federal bank supervision that Anchorage faces.
Grayscale’s decision to make the switch specifically in an amended filing – after initially naming Coinbase – suggests the move was deliberate rather than default. The timing coincides with broader SEC engagement under Chair Paul Atkins and the agency’s “Project Crypto” system, which has pushed issuers to tighten their regulatory positioning.
Coinbase’s Custody Dominance Under Pressure
Coinbase currently custodies Bitcoin for eight of the eleven U.S. spot Bitcoin ETFs, including BlackRock’s iShares Bitcoin Trust (IBIT), the largest cryptocurrency ETF by assets. That concentration has drawn attention from regulators, industry analysts, and competing custodians who argue that a single point of failure across the majority of institutional Bitcoin exposure creates systemic risk.
The Grayscale filing is the first concrete signal that an issuer is actively diversifying away from Coinbase for a new product rather than defaulting to the incumbent. If the SEC approves the Hyperliquid ETF with Anchorage as custodian, it would establish a precedent for future DeFi-focused ETFs to use alternative custody providers.
CryptoSlate noted that the move shines a light on how much of Wall Street’s Bitcoin infrastructure still depends on one custodian. Coinbase’s dominance in ETF custody isn’t a market failure – the company won those mandates through competitive bidding – but the resulting concentration has become a talking point in regulatory discussions about crypto market structure.
The Hyperliquid ETF Itself
Hyperliquid is a decentralized perpetual futures exchange operating its own Layer 1 blockchain. The platform has grown rapidly, becoming a hub for used crypto trading with deep liquidity across major trading pairs.
An ETF tracking HYPE would give institutional investors exposure to a DeFi infrastructure token rather than a currency or store-of-value asset. The product represents Grayscale’s push into what it considers the next wave of crypto investment products: tokens tied to protocol revenue and network usage rather than simple price appreciation.
The amended S-1 doesn’t change the fundamental structure of the ETF or its investment thesis. The only modification is the custodian designation, which Grayscale evidently considered important enough to refile.
What This Means for the Broader Market
If Anchorage establishes itself as a viable alternative custodian for crypto ETFs, the custody field could fragment – in a healthy way. Multiple custodians competing for ETF mandates would reduce single-entity risk, potentially lower custody fees through competition, and give issuers more flexibility in structuring products for different asset types.
Fidelity and BitGo already provide custody for some existing crypto ETFs, but neither has a federal bank charter. Anchorage’s unique regulatory positioning could make it the preferred custodian for more experimental products, particularly DeFi-focused ETFs where the underlying assets don’t fit neatly into traditional custody workflows.
The institutional crypto custody market was valued at roughly $350 billion in assets under custody as of Q1 2026, with Coinbase controlling an estimated 60 percent of the ETF-related segment. Any meaningful redistribution of that share would represent a structural shift in crypto’s institutional plumbing.
FAQ
Does this mean Coinbase is losing its ETF custody business?
Not yet. Coinbase still custodies the vast majority of U.S. crypto ETF assets, including BlackRock’s IBIT. Grayscale’s move affects only the Hyperliquid ETF filing, but it could signal a broader trend if other issuers follow suit.
What is Anchorage Digital Bank?
Anchorage is the first federally chartered crypto-native bank in the United States, authorized by the OCC. It provides custody, staking, governance, and trading services for institutional clients.
When will the Grayscale Hyperliquid ETF launch?
No approval date has been set. The amended S-1 filing is under SEC review, and the timeline depends on the agency’s evaluation of the product’s structure, custody arrangements, and market surveillance agreements.
