- Coinbase serves as both custodian and prime execution agent, splitting the 18% with BlackRock

- The fund charges a 0.25% annual sponsor fee, reduced to 0.12% for the first $2.5 billion in assets
Breaking Down the Fee Structure
BlackRock's iShares Staked Ethereum Trust ETF, which will trade under the ticker ETHB, takes an 18% cut of all staking rewards generated by the fund's ETH holdings. This fee is split between BlackRock and Coinbase, which serves as both the fund's custodian and prime execution agent. The exact revenue split between the two firms was not disclosed in the filing.
On top of the staking fee, the fund charges a 0.25% annual sponsor fee—the standard management expense for operating the ETF. As an introductory offer, this sponsor fee is reduced to 0.12% for the first $2.5 billion in assets under management, likely a strategy to quickly attract capital and establish market share against competing products.
How the Staking Mechanics Work
Under normal market conditions, between 70% and 95% of the trust's ETH holdings will be actively staked on the Ethereum network. The remaining 5–30% will be held as liquid reserves to handle daily ETF redemptions without requiring unstaking, which currently involves a variable exit queue that can take anywhere from hours to days depending on network conditions.
The staking is performed through Coinbase's institutional staking infrastructure, which operates a fleet of Ethereum validators. Current Ethereum staking yields sit at approximately 3.2% annually, meaning the 18% fee reduces the effective yield passed through to ETF holders to roughly 2.6%. For a $10,000 investment, that translates to approximately $260 in annual staking rewards versus $320 without the fee—a $60 annual cost for the convenience of ETF access.
How It Compares to Competitors
The 18% staking fee positions BlackRock's offering in the middle of the pack among proposed staking Ethereum ETFs. Fidelity's competing product has proposed a 15% staking reward fee, while 21Shares filed with a 25% cut. For context, retail investors who stake ETH directly through platforms like Lido pay an effective 10% fee, and solo stakers who run their own validators pay nothing beyond hardware and electricity costs.
The sponsor fee comparison is more favorable for BlackRock. At 0.25% (or 0.12% with the introductory discount), ETHB is competitive with the existing iShares Ethereum Trust ETF (ETHA), which charges 0.25%. The combined total cost of ownership—factoring in both the sponsor fee and the staking revenue cut—will be the key metric for institutional allocators comparing products.
Why This Matters for Ethereum
The launch of staking-enabled Ethereum ETFs represents a significant development for the Ethereum ecosystem. If ETHB attracts the same level of institutional interest as BlackRock's spot Bitcoin ETF (IBIT), which accumulated over $20 billion in its first year, it could direct billions of dollars worth of ETH into staking—further securing the network while reducing circulating supply.
At the upper bound of 95% staked, a $10 billion ETF would lock approximately 3.8 million ETH in proof-of-stake validators, representing roughly 12% of all currently staked ETH. This level of institutional staking participation could have meaningful effects on both network security and ETH supply dynamics, potentially creating upward price pressure as more ETH is removed from liquid circulation.
Regulatory and Market Outlook
The SEC's willingness to allow staking within an ETF wrapper marks a departure from its earlier stance, when the commission specifically excluded staking from the initial wave of spot Ethereum ETF approvals in mid-2024. Industry observers see this as a signal that the regulatory environment for crypto investment products continues to evolve toward greater functionality and feature parity with direct on-chain participation.
BlackRock has not announced a specific launch date for ETHB, but market expectations point to a Q2 2026 listing pending final SEC approval. The fund will be available through standard brokerage accounts, making staking yield accessible to retirement accounts, institutional portfolios, and retail investors who prefer traditional financial infrastructure over direct crypto custody.
