Key Takeaways
- • Grayscale amended its Hyperliquid ETF filing on April 20, 2026, replacing Coinbase with Anchorage Digital Bank as the primary custodian for HYPE token holdings, while retaining BNY Mellon as transfer agent.
- • The custodian shift reflects a diversification strategy away from Coinbase, which currently holds custody for nearly all U.S.-traded spot bitcoin ETFs and represents a significant concentration point in the crypto ETF infrastructure landscape.
- • Anchorage Digital Bank, the first federally chartered crypto bank in the United States (founded 2017), has emerged as a credible alternative custodian, having previously served as a secondary custodian for Grayscale's Bitcoin and Ethereum trusts since August 2025.
- • The move signals institutional appetite for custody optionality in emerging crypto asset classes and aligns with broader industry efforts to reduce systemic concentration risk in crypto custody services.
- • Hyperliquid's HYPE token represents a growing asset class in decentralized finance, with the token listed on Coinbase in February 2026 following the protocol's rapid scaling in 2025.
Summary
Grayscale Investments submitted an amended S-1 registration statement to the Securities and Exchange Commission on April 20, 2026, updating its Hyperliquid ETF (HYPE) filing to designate Anchorage Digital Bank as the fund's custodian, replacing Coinbase in that primary role. The amendment maintains BNY Mellon as the transfer agent. This custodial restructuring marks a strategic shift in how Grayscale addresses custody arrangements for its emerging crypto asset products.
The decision carries material significance given Coinbase's dominant position in crypto custody infrastructure. Coinbase Custody Trust Company currently serves as the primary custodian for substantially all U.S.-traded spot bitcoin ETFs, with Fidelity Digital Assets representing a notable exception. This concentration has become a focal point for institutional investors and regulators evaluating systemic risks in the ETF custody ecosystem. By pivoting to Anchorage for the HYPE ETF, Grayscale is explicitly diversifying away from this chokepoint—a consideration likely to resonate with large institutional allocators concerned about custody concentration.
Anchorage Digital Bank, founded in 2017, holds established credentials as a regulated custodian. The firm earned federal charter status as the first U.S.-based crypto bank and has already demonstrated utility within Grayscale's product suite, having been appointed as a secondary custodian for portions of Grayscale's Bitcoin and Ethereum trust holdings in August 2025. Recent expansion efforts by Anchorage—including scaling into stablecoin custody, wealth management, and token lifecycle management—suggest the firm is positioned to capture demand for custody services across multiple asset classes.
Hyperliquid itself represents an emerging protocol within the decentralized finance ecosystem, with its native HYPE token reaching institutional visibility following listing on Coinbase in February 2026. The protocol's perpetuals DEX platform has experienced significant growth during 2025, though notably remains ring-fenced from U.S. market participation, which may shape the ETF's regulatory pathway and investor base composition. The Grayscale HYPE ETF filing reflects institutional appetite for structured exposure to novel crypto assets alongside efforts to establish robust operational and custodial infrastructure.
