BlackRock, the world’s largest asset manager, recently listed a distinctive crypto ETF on the Nasdaq — the iShares Staked Ethereum Trust ETF (ETHB). This is its third crypto ETF, with the core feature being the provision of a compliant channel for investors to gain exposure to Ethereum staking yields.
On its debut day, ETHB recorded a trading volume of approximately $15.5 million, which surged to around $76 million the following day. Its assets under management have also grown rapidly, from about $100 million at launch to its current size of roughly $170 million. Although dubbed by many reports as the “first Ethereum staking ETF in the U.S.,” it is not actually the pioneer, yet it is undoubtedly the most significant entrant.
To understand ETHB, one must first grasp Ethereum’s “staking” mechanism. Since “The Merge” in 2022, Ethereum (ETH.CC) has adopted the Proof-of-Stake consensus mechanism to maintain network security. Simply put, it involves locking ETH in the network to participate in validation, for which the system rewards participants, akin to interest on a deposit. The current annualized yield is approximately 2.78%. For long-term holders, especially institutions managing substantial assets, this additional return is crucial; missing out on it represents an opportunity cost.
What ETHB does is to formalize and productize this process compliantly. Investors, through regular securities accounts, gain exposure to Ethereum’s price while also sharing in the staking yield, without needing to research the technology themselves or select validation nodes.
ETHB’s fees are structured in two layers. The first layer is the explicit management fee, set at 0.25% per annum, or 0.12% during a promotional period lasting either 12 months or until the fund reaches $2.5 billion in assets.
The second layer is the staking fee split. Of the staking rewards generated, 82% are allocated to ETF holders, while the remaining 18% are taken as a staking fee, paid to the trust’s sponsor, BlackRock’s iShares Delaware Trust Sponsor LLC, and the brokerage execution agent Coinbase (COIN). Coinbase then pays downstream validator operators, including Figment, Galaxy Digital (GLXY), and Attestant.
According to the filing, ETHB will stake between 70% and 95% of its held ETH through the custodian, Coinbase Custody Trust Company. As of March 12th, its staking ratio was approximately 80%, but after an increase in fund size on the 13th, this ratio dropped to 56%.
Based on calculations, assuming a nominal staking annualized yield of 2.78%, after deducting the two layers of fees, the actual annualized yield received by investors would be approximately between 1.35% and 2.05%, depending on the current staking ratio and whether the promotional period applies. Despite the notable cost, it provides a compliant channel to obtain staking yields without needing to self-custody private keys or operate nodes. For regulated institutions, this premium holds significant value.
When spot Ethereum ETFs were approved in 2024, the U.S. Securities and Exchange Commission explicitly prohibited the funds from staking their held ETH. The regulatory logic at that time considered staking might constitute an offering of securities. This restriction began to ease in 2025. In May of that year, the SEC’s Division of Corporation Finance issued guidance, opening the legal door for Ethereum staking ETFs.
BlackRock’s ETHB submitted a complete S-1 registration statement and 19b-4 rule change proposal. After approximately three months of review, it was listed in March this year. This most standard and transparent pathway has granted it the core competitiveness to attract institutions: the lowest fee rate.
