The iShares Staked Ethereum Trust (ETHB) is a spot Ethereum exchange-traded product (ETP) issued by BlackRock. Launched on March 12, 2026, the fund is designed to provide investors with direct exposure to the price of Ethereum (ETH) while also generating income by staking a significant portion of its underlying ether holdings. ^{[1] [2]} It trades on the Nasdaq exchange under the ticker symbol ETHB. ^[3]

Overview

The iShares Staked Ethereum Trust (ETHB) was created to function as a total-return product, combining potential price appreciation of Ethereum with an income stream derived from network staking rewards. ^[4] It is BlackRock's third major digital asset ETP, following the successes of the iShares Bitcoin Trust (IBIT) and the non-staked iShares Ethereum Trust (ETHA). The fund offers an alternative to ETHA, allowing investors to choose between pure price exposure and a model that incorporates yield. ^[1]​

The fund's investment objective is to reflect the performance of ether's price, as measured by the CME Ethereum (NY Close) benchmark index, in combination with the rewards earned from its staking activities. ETHB provides a way for investors to access both components through a traditional brokerage account, abstracting away the technical complexities of directly holding and staking ETH. ^[3] In the announcement of the fund's launch, Robert Mitchnick, BlackRock's Global Head of Digital Assets, stated that the product allows investors "to participate in the evolution of the Ethereum ecosystem, which is central to the growth of blockchain adoption and decentralized applications." ^[2]​

History and Development

The development of ETHB began with BlackRock filing an initial S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) in December 2025. This was followed by an amended S-1 filing on February 17, 2026, which provided more detailed information about the fund's proposed structure and staking strategy. ^[5]

As a procedural step to activate the ETF's creation mechanism, a BlackRock affiliate seeded the trust with an investment of $100,000. This involved the purchase of 4,000 initial shares at a price of $25.00 per share. ^[5] Another source noted an earlier seed investment on December 17, 2025, where a Seed Capital Investor purchased 4,000 shares at $0.25 per share for a total of $1,000. ^[4]

The official inception date for the trust was February 18, 2026. ^[3] The fund officially launched and began trading on the Nasdaq on March 12, 2026. ^[1] By March 11, 2026, one day before its public launch, the trust held net assets of $106,725,949, representing 4,000,000 outstanding shares. ^[3]

Fund Structure and Staking Mechanism

Asset Allocation

The fund is structured to dynamically stake a majority of its Ethereum holdings while retaining a portion for liquidity. The trust's strategy is to stake between 70% and 95% of its total ETH assets at any given time. ^[1] To manage daily redemptions and other liquidity needs, the fund maintains a "liquidity sleeve," keeping between 5% and 30% of its ETH holdings unstaked. ^[4] As an example of this allocation in practice, the trust's reported holdings on March 10, 2026, consisted of approximately 80% staked ether (represented as SETH) and 20% unstaked ether (ETH). ^[3]​

Staking Rewards and Distribution

A core feature of ETHB is the distribution of staking rewards to its shareholders. The fund passes through 82% of the gross staking rewards generated from its activities to investors. ^{[1] [4]} The remaining 18% of gross rewards is retained by the trust to cover its own costs as well as fees for the sponsor, custodian, and other service providers. This 18% portion is referred to as the "Staking Reward Commission." ^[5]​

The rewards are distributed to shareholders in the form of monthly income payments. ^{[1] [3]} While not guaranteed, early 2026 filings for the ETF, citing network benchmarks, projected an average annualized staking yield of approximately 3%. ^[5]​

Trading and Redemption

Shares of ETHB are traded on the Nasdaq stock exchange, making them accessible to investors through standard brokerage accounts. The fund's CUSIP number is 46438M106. ^[6] However, the shares are not individually redeemable directly from the trust by retail investors. Instead, only a group of institutional firms known as "Authorized Participants" can create or redeem shares. This process is done in large blocks, referred to as "Baskets," which are standardized units of 40,000 shares. ^{[3] [5]}​

Fee Structure

ETHB has a multi-layered fee structure that includes an annual Sponsor Fee charged on total assets and a Staking Service Fee deducted from gross staking rewards. ^[1]

Sponsor Fee

The standard annual Sponsor Fee for the trust is 0.25% of its net asset value. ^{[3] [4]}

However, BlackRock introduced a promotional fee waiver for the fund's first year of trading. Commencing on March 12, 2026, and lasting for 12 months, the Sponsor Fee is reduced to 0.12% on the first $2.5 billion of the trust's assets. For any assets under management exceeding the $2.5 billion threshold during this period, the standard 0.25% fee applies. After the 12-month waiver period concludes, the 0.25% fee will apply to all assets held by the trust. ^{[5] [2]}

Staking Service Fee

In addition to the Sponsor Fee, a service fee is deducted directly from the gross staking rewards before they are distributed to shareholders. This is part of the 18% of rewards that the fund retains. A "base staking fee" is paid to Coinbase, which acts as the custodian and staking partner. This fee is set at 10% of all gross staking rewards generated. The fee structure includes a provision for a reduced rate; if the fund's total Assets Under Management (AUM) surpass $20 billion, the fee paid to Coinbase for its staking services decreases to 6%. ^[1]

Ecosystem and Operations

Key Entities

The operation of ETHB relies on a network of established firms in the traditional finance and digital asset sectors:

• Issuer and Manager: BlackRock, the world's largest asset manager, issues the fund. ^[1]
• Sponsor: The fund is sponsored by iShares Delaware Trust Sponsor LLC, a subsidiary of BlackRock. ^[2]
• Primary Custodian and Prime Execution Agent: Coinbase serves multiple key roles, including custody of the underlying ETH assets through Coinbase Custody Trust Company, LLC, and trade execution via its Coinbase Prime platform. ^{[3] [4]}
• Alternative Custodian: Anchorage Digital Bank N.A. is listed as an alternative custodian for the fund. ^[5]
• Key Figure: Robert Mitchnick serves as BlackRock's Global Head of Digital Assets and is a primary spokesperson for its crypto ETPs. ^[2]

Staking Operations

The fund's staking activities are managed through a selection of approved third-party validator service providers. The list of approved validators includes Figment Inc., Galaxy Blockchain Infrastructure LLC, and Attestant Limited. Coinbase is tasked with the initial review and approval of these validators. ^[1]​

To enhance security and operational integrity, BlackRock imposes strict mandates on its staking partners. These rules require that validators do not pool or commingle the fund's ETH with other client assets. Furthermore, validators must use separate, dedicated cryptographic keypairs exclusively for the fund's operations. The fund's holdings and on-chain activity are designed to be transparent and can be tracked on public blockchain explorers. Due to the T+1 settlement cycle of traditional finance, on-chain transactions reflecting the fund's ETH purchases typically become visible one business day after a trade is executed. ^{[1] [4]}​

Market Context and Competition

ETHB launched into an increasingly competitive market for yield-bearing and staked Ethereum financial products. It is aimed at both existing holders of BlackRock's non-staked ETHA fund and investors who previously staked ETH on their own. The fund's structure positions it against several competing products from other asset managers.

Key competitors in the staked Ethereum ETF space include:

• Grayscale Ethereum Staking ETF (ETHE): This fund has a higher management fee of 2.5% and passes through a smaller portion of staking rewards to investors, at 77%.
• Grayscale Ethereum Mini Trust (ETH): A lower-cost option from Grayscale, this fund has a 0.15% management fee and a high reward pass-through rate of 94%.
• REX-Osprey ETH + Staking ETF: Launched in September 2025, this fund operates with a "fund of funds" structure. It has a 0.75% management fee but is designed to pass on 100% of staking rewards to investors.

The launch of ETHB provides investors with another option that balances management fees and reward pass-through from a major institutional issuer. ^[1]​

Regulatory Status and Risks

The iShares Staked Ethereum Trust (ETHB) operates under a specific regulatory classification that distinguishes it from many traditional investment products. The trust is not registered as an investment company under the Investment Company Act of 1940 and is not regulated as a commodity pool under the Commodity Exchange Act. As a result, shareholders of ETHB do not receive the same regulatory protections and oversight that apply to mutual funds or other ETFs registered under these acts. ^{[3] [2]}

The fund's prospectus details several key risks associated with an investment in ETHB, which is considered a speculative investment involving a high degree of risk: ^[6]

• Market and Volatility Risk: The value of ETHB shares is subject to the extreme price volatility inherent in digital assets like Ethereum.
• Staking-Specific Risks: The process of staking introduces unique risks, including the potential loss of staked ether principal due to network penalties known as "slashing," which can occur if a validator acts maliciously or fails to perform its duties. Staked assets are also subject to network-enforced activation and withdrawal periods, which can create illiquidity. Finally, the generation of staking rewards is not guaranteed and can fluctuate based on network conditions.
• Market Price vs. NAV Risk: Shares may trade on the stock market at a price that is higher or lower than the value of the underlying ether they represent (a premium or discount). ^[6]
• Counterparty Risk: The fund is exposed to the operational and financial stability of its third-party service providers, including its custodian (Coinbase) and approved staking validators. A failure by any of these counterparties could adversely affect the trust.
• Operational Risk: The security of the trust's assets depends on the safeguarding of private cryptographic keys. The loss, theft, or compromise of these keys could result in a permanent loss of the underlying ether. Additionally, a significant disruption to the internet or the Ethereum network itself could negatively impact the fund.
• Structural Dilution: The amount of ether represented by each share of ETHB is expected to decrease over time. This is because the trust must regularly sell a portion of its ether holdings to pay for the Sponsor's Fee and other ongoing operational expenses.

These risk factors are inherent to an investment in a digital asset ETP that incorporates staking. ^{[3] [2]}
