Grayscale Investments has amended its Hyperliquid ETF registration with the U.S. Securities and Exchange Commission, replacing Coinbase Custody with Anchorage Digital Bank as the proposed fund’s custodian. The revision marks a meaningful operational change inside the filing, because custody is not a peripheral service in an ETF structure but a core control point tied to asset protection, legal responsibility and day-to-day fund operations.
The amendment, submitted on April 20, 2026, updates the public registration record and changes the institutional counterparty assigned to safeguard the assets tied to the proposed vehicle. Grayscale has framed the adjustment around evolving market conditions, regulatory considerations and internal risk management, but the practical effect is more concrete: the operational backbone of the HYPE ETF now rests on a different custody provider. That means legal, compliance and treasury teams following the application will need to reassess the filing through the lens of a new custody relationship rather than treat the amendment as a routine administrative edit.
The Filing Change Reassigns a Core Layer of Fund Risk
A custodian substitution inside an ETF registration has consequences that go beyond disclosure language. The revised filing effectively reallocates legal and operational responsibility for safekeeping, reconciliation and custody controls, which makes the amendment a shift in risk architecture as much as a change in service provider. For institutions reviewing the HYPE filing, that raises immediate questions around segregation mechanics, continuity arrangements, audit standards and the exact custody services being represented in the registration materials.
The change also affects how counterparties evaluate the proposed product before any approval decision is reached. Internal risk teams will likely revisit custody agreements, service-level expectations, counterparty concentration limits and incident-response assumptions, because a new custodian changes the map of operational dependencies attached to the ETF. In that sense, the substitution matters not only to regulators reviewing the filing, but also to allocators, compliance officers and governance teams that monitor operational quality before committing capital to an eventual listed product.
Institutional Review Now Moves Beyond the Headline Change
For market participants tracking the HYPE ETF, the larger takeaway is procedural. Material changes in registration documents can alter how a product is evaluated internally, especially where custody, oversight and prudential controls are concerned. That makes ongoing review of amended filings an essential part of ETF due diligence, particularly in digital-asset products where custody remains one of the most scrutinized elements of the structure.
The immediate next step is likely to be follow-through documentation and governance updates tied to the new custodian arrangement. Until that process is clearer, the amendment stands as a reminder that operational details inside an ETF filing can shift in important ways before approval, and that those changes can materially affect how institutions assess risk, stewardship and reporting obligations. For the HYPE ETF, the custodian switch is now one of the most important non-price developments in the filing record.
