Grayscale has updated its filing for its Hyperliquid-linked ETF, changing the custodian to Anchorage Digital Bank, replacing Coinbase as the prime broker and custodian. This change is noteworthy because Coinbase has long dominated the crypto ETF custody market, currently providing custody services for almost all US spot Bitcoin ETFs (except Fidelity). The filing shows that Bank of New York Mellon will remain the transfer agent for the ETF (proposed ticker symbol GHYP). The fund's staking functionality still requires regulatory approval and will use Hyperliquid benchmark pricing data from CoinDesk. Furthermore, Anchorage Digital Bank, as the first federally chartered crypto bank in the US, has been continuously expanding its institutional service capabilities in recent years, including stablecoins, wealth management, and token lifecycle management.
