BlackRock has officially filed an S-1 with the SEC to launch the iShares Ethereum Staking Trust (ETHB), which would track Ethereum’s price and distribute staking rewards quarterly. The fund plans to stake 70–90% of its ETH holdings, with Coinbase Custody Trust as primary custodian and Anchorage Digital Bank as an alternative. Bank of New York Mellon will handle cash custody and administration. ETHB will operate independently from BlackRock’s existing iShares Ethereum Trust ETF (ETHA), which holds $11 billion in AUM. The filing comes after last month’s Delaware registration of the product name and follows speculation in the crypto community. As of the news, Ethereum trades at $3,114, up 13.7% over the week.
