PROSPECTUS

SUBJECT TO COMPLETION, DATED JULY 11, 2025

iShares^® Ethereum Trust ETF

The iShares Ethereum Trust ETF (the “Trust”) is a Delaware statutory trust that issues shares (“Shares”) representing fractional undivided beneficial interests in its net assets. The assets of the Trust consist primarily of ether held by a custodian on behalf of the Trust. The Trust seeks to reflect generally the performance of the price of ether. The Trust seeks to reflect such performance before payment of the Trust’s expenses and liabilities. iShares Delaware Trust Sponsor LLC (the “Sponsor”) is the sponsor of the Trust; Wilmington Trust, National Association, a national association (the “Delaware Trustee”), is the Delaware trustee of the Trust; BlackRock Fund Advisors (the “Trustee”) is the trustee of the Trust; Coinbase Custody Trust Company, LLC, (the “Ether Custodian”) is the custodian for the Trust’s ether holdings; Anchorage Digital Bank N.A. (the “Additional Ether Custodian”) is an available alternative custodian for the Trust’s ether holdings; and The Bank of New York Mellon is the custodian for the Trust’s cash holdings (the “Cash Custodian” and together with the Ether Custodian and the Additional Ether Custodian, the “Custodians”) and the administrator of the Trust (the “Trust Administrator”). The Trust is not an investment company registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and the Sponsor is not registered with the Securities and Exchange Commission (“SEC”) as an investment adviser and is not subject to regulation by the SEC as such in connection with its activities with respect to the Trust. The Trust is not a commodity pool for purposes of the Commodity Exchange Act of 1936, as amended (the “Commodity Exchange Act” or “CEA”), and the Sponsor is not subject to regulation by the Commodity Futures Trading Commission (the “CFTC”) as a commodity pool operator or a commodity trading advisor with respect to the Trust.

The Trust intends to issue Shares on a continuous basis and is registering an indeterminate number of Shares with the SEC in accordance with Rule 456(d) and 457(u). The Trust issues and redeems Shares only in blocks of 40,000 or integral multiples thereof, based on the quantity of ether attributable to each Share (net of accrued but unpaid remuneration due to the Sponsor (the “Sponsor’s Fee”) and any accrued but unpaid expenses or liabilities). A block of 40,000 Shares is called a “Basket.” These transactions take place in exchange for ether or cash. Baskets will be offered continuously at the net asset value per Share (“NAV”) for 40,000 Shares. Only registered broker-dealers that become authorized participants by entering into a contract with the Sponsor and the Trustee (“Authorized Participants”) may purchase or redeem Baskets. Shares will be offered to the public from time to time at varying prices that will reflect the price of ether and the trading price of the Shares on The Nasdaq Stock Market LLC (“NASDAQ” or the “Exchange”) at the time of the offer.

The Authorized Participants will deliver only ether or cash to create Shares and will receive only ether or cash when redeeming Shares.

Neither the Trust, nor the Sponsor, nor the Ether Custodian, nor any other person associated with the Trust will, directly or indirectly, employ any portion of the Trust’s assets in actions where any portion of the Trust’s ether becomes subject to the Ethereum proof-of-stake validation or is used to earn additional ether or generate income or other earnings (collectively, “Staking Activities”). Accordingly, the Trust will not earn any form of staking rewards, or income of any kind, from Staking Activities.

Table of Contents

The Shares are listed and traded on NASDAQ under the ticker symbol “ETHA.” Market prices for the Shares may be different from the NAV.

CME CF Ether–Dollar Reference Rate – New York Variant for the ether – U.S. Dollar trading pair (the “CF Benchmarks Index”), produced by CF Benchmarks Ltd., on July 7, 2025 was $2,548.02.

Except when aggregated in Baskets, Shares are not redeemable securities. Baskets are only redeemable by Authorized Participants.

The Trust is an “emerging growth company,” as that term is used in the Jumpstart Our Business Startups Act (the “JOBS Act”), subject to reduced public company reporting requirements under U.S. federal securities laws.

Investing in the Shares involves significant risks. See “Risk Factors” starting on page 16.

Neither the SEC nor any state securities commission has approved or disapproved of the securities offered in this prospectus, or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The Shares are not interests in nor obligations of any of the Sponsor, the Trustee, the Delaware Trustee, BlackRock Financial Management, Inc. (the “Seed Capital Investor”), the Administrator, the Cash Custodian, the Ether Custodian, the Additional Ether Custodian, or their respective affiliates. The Shares are not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other governmental agency.

“iShares” is a registered trademark of BlackRock, Inc. or its affiliates.

On May 21, 2024, the Seed Capital Investor, an affiliate of the Sponsor, subject to conditions, purchased the Seed Creation Baskets, comprising 400,000 Shares at a per-Share price equal to $25.00. Total proceeds to the Trust from the sale of the Seed Creation Baskets were $10,000,000. On June 24, 2024, the Trust purchased 3,030.72569755 ether with the proceeds of the Seed Creation Baskets using the Prime Execution Agent. The Seed Capital Investor has acted as a statutory underwriter in connection with this purchase. See “Seed Capital Investor” and “Plan of Distribution” for additional information.

The price of the Seed Creation Baskets was determined as described above and such Shares could be sold at different prices if sold by the Seed Capital Investor at different times.

STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus includes statements which relate to future events or future performance. In some cases, you can identify such forward-looking statements by terminology such as “may,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or the negative of these terms or other comparable terminology. All statements (other than statements of historical fact) included in this prospectus that address activities, events or developments that may occur in the future, including such matters as changes in commodity prices and market conditions (for ether and the Shares), the Trust’s operations, the Sponsor’s plans and references to the Trust’s future success and other similar matters are forward-looking statements. These statements are only predictions. Actual events or results may differ materially. These statements are based upon certain assumptions and analyses made by the Sponsor on the basis of its perception of historical trends, current conditions and expected future developments, as well as other factors it believes are appropriate in the circumstances. Whether or not actual results and developments will conform to the Sponsor’s expectations and predictions, however, is subject to a number of risks and uncertainties, including the special considerations discussed in this prospectus, general economic, market and business conditions, changes in laws or regulations, including those concerning taxes, made by governmental authorities or regulatory bodies, and other world economic and political developments. See “Risk Factors.” Consequently, all the forward-looking statements made in this prospectus are qualified by these cautionary statements, and there can be no assurance that the actual results or developments the Sponsor anticipates will be realized or, even if substantially realized, will result in the expected consequences to, or have the expected effects on, the Trust’s operations or the value of the Shares. None of the Trust, the Sponsor, the Trustee or the Delaware Trustee or their respective affiliates is under a duty to update any of the forward-looking statements to conform such statements to actual results or to a change in the Sponsor’s expectations or predictions.

PROSPECTUS SUMMARY

Although the Sponsor believes that this summary is materially complete, you should read the entire prospectus, including “Risk Factors” beginning on page 16, before making an investment decision about the Shares.

Definitions of terms used in this prospectus can be found in the Glossary on page 139.

Trust Structure, the Sponsor, the Trustee, the Delaware Trustee and the Custodians

The Trust was formed as a Delaware statutory trust on November 9, 2023. The purpose of the Trust is to own ether transferred to or purchased by the Trust in exchange for Shares issued by the Trust. Each Share represents a fractional undivided beneficial interest in the net assets of the Trust. The assets of the Trust consist primarily of ether held by the Ether Custodian pursuant to the Custodial Services Agreement between Coinbase Custody and the Trust (the “Custodian Agreement”) on behalf of the Trust. The Trust has also entered into a custody agreement with the Additional Ether Custodian pursuant to the Master Custody Services Agreement between Anchorage and the Trust (the “Anchorage Custodian Agreement”). The Trust is not required to hold any particular amount of assets at either the Ether Custodian or the Additional Ether Custodian, and the Sponsor shall, in its sole discretion, determine the amounts held at either custodian from time to time as permitted by the Trust Agreement. As of the date of this prospectus, the Trust’s ether is held with the Ether Custodian, and the Sponsor has no plans to move any of the Trust’s ether to the Additional Ether Custodian, though such plans are subject to ongoing review. The addition of the Additional Ether Custodian as an available alternative custodian of the Trust’s ether reflects the Sponsor’s ongoing risk management approach as part of the Trust’s growing size and the Sponsor’s expanding presence in the digital asset space.

The Sponsor of the Trust is iShares Delaware Trust Sponsor LLC, a Delaware limited liability company and an indirect subsidiary of BlackRock, Inc. (“BlackRock”). The Shares are not obligations of, and are not guaranteed by, iShares Delaware Trust Sponsor LLC, or any of its subsidiaries or affiliates.

The Trust is governed by the provisions of the Third Amended and Restated Trust Agreement executed as of July 8, 2025 by the Sponsor, the Trustee and the Delaware Trustee (as amended from time to time, the “Trust Agreement”).

The Trust issues and redeems Shares only in Baskets of 40,000 or integral multiples thereof, based on the quantity of ether attributable to each Share (net of accrued but unpaid Sponsor’s Fee and any accrued but unpaid expenses or liabilities). Baskets may be redeemed by the Trust in exchange for either (1) the cash proceeds from selling the amount of ether corresponding to their redemption value or (2) the amount of ether corresponding to their redemption value. These transactions take place in exchange for cash or ether. Individual Shares will not be redeemed by the Trust but will be listed and traded on NASDAQ under the ticker symbol “ETHA.” The Trust seeks to reflect generally the performance of the price of ether. The Trust seeks to reflect such performance before payment of the Trust’s expenses and liabilities. The material terms of the Trust are discussed in greater detail under the section “Description of the Shares and the Trust Agreement.” The Trust is a passive investment vehicle that does not seek to generate returns beyond tracking the price of ether. This means the Sponsor does not speculatively sell ether at times when its price is high or speculatively acquire ether at low prices in the expectation of future price increases. It also means the Trust will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. The Trust, the Sponsor and the Trust’s service providers will not loan, pledge or rehypothecate the Trust’s assets, nor will the Trust’s assets serve as collateral for any loan or similar arrangement, except with respect to securing the repayment of Trade Credits (as defined below). See “The Custodians—The Ether Custodian and the Additional Ether Custodian” and “The Prime Execution Agent and the Trade Credit Lender—The Prime Execution Agent.” The Trust is not a registered investment company under the Investment Company Act and is not required to register under the Investment Company Act. The Sponsor is not registered with the SEC as an investment adviser and is not subject to regulation by the SEC as such in connection with its activities with respect to the Trust. The Trust is not a commodity pool for purposes of the CEA, and the Sponsor is not subject to regulation by the CFTC as a commodity pool operator or a commodity trading advisor in connection with its activities with respect to the Trust.

The Trust intends to continuously offer Shares but may suspend issuances of Shares at any time.

The Sponsor has arranged for the creation of the Trust, the registration of the Shares for their public offering in the United States and the listing of the Shares on NASDAQ. The Sponsor has agreed to assume the marketing and the following administrative expenses incurred by the Trust: the fees of the Trustee, the Delaware Trustee and the Trust Administrator, the Custodians’ fee (the “Custodians’ Fee”), NASDAQ listing fees, SEC registration fees, printing and mailing costs, tax reporting fees, audit fees, license fees and expenses and up to $500,000 per annum in ordinary legal fees and expenses. The Sponsor will also pay the costs of the Trust’s organization and the initial sale of the Shares. The Sponsor may determine in its sole discretion to assume legal fees and expenses of the Trust in excess of the $500,000 per annum required under the Trust Agreement. To the extent that the Sponsor does not voluntarily assume such fees and expenses, they will be the responsibility of the Trust.

Table of Contents

The Sponsor will maintain a public website on behalf of the Trust, containing information about the Trust and the Shares. The Internet address of the Trust’s website is www.iShares.com. This Internet address is only provided here as a convenience to you, and the information contained on or connected to the Trust’s website is not considered part of this prospectus. The Sponsor is responsible for oversight and overall management of the Trust but has delegated day-to-day administration of the Trust to the Trustee under the Trust Agreement. The Sponsor may remove the Trustee and appoint a successor trustee in its discretion or if, having received written notice of a material breach of its obligations under the Trust Agreement, the Trustee has not cured the breach within thirty days. The Sponsor may also replace the Trustee during the 90 days following any merger, consolidation or conversion in which the Trustee is not the surviving entity. The Trustee also has the right to select any new or additional custodians.

The Sponsor, the Trustee or any of their respective affiliates and associates currently engage in, and may in the future engage in, the promotion, management or investment management of other accounts, funds or trusts that invest primarily in ether or another digital asset, or may face other potential conflicts of interest. Although officers and professional staff of the Sponsor’s or the Trustee’s management intend to devote as much time to the Trust as is deemed appropriate to perform their duties, the Sponsor’s or the Trustee’s management may allocate their time and services among the Trust and the other accounts, funds or trusts. In addition, the Sponsor and the Trustee may agree to amend the Trust Agreement, including to increase the Sponsor’s Fee, without Shareholder consent. See “Conflicts of Interest.”

The Trustee is BlackRock Fund Advisors, the Delaware Trustee is Wilmington Trust, National Association, the Ether Custodian is Coinbase Custody Trust Company, LLC (“Coinbase Custody”), and the Cash Custodian and the Trust Administrator is The Bank of New York Mellon.

Subject to the Sponsor’s oversight, the Trustee is generally responsible for the management and day-to-day operations of the Trust. The responsibilities of the Trustee include (1) processing orders for the creation and redemption of Baskets; (2) coordinating with the Ether Custodian and Prime Execution Agent the receipt and delivery of ether purchased or sold by or otherwise transferred to, or by, the Trust and with the Cash Custodian or Ether Custodian the receipt and delivery of cash or ether transferred to or by the Trust in connection with each issuance and redemption of Baskets; (3) calculating the net asset value of the Trust on any day other than: a Saturday or a Sunday, or a day on which NASDAQ is closed for regular trading (“Business Day”); and (4) selling the Trust’s ether as needed to cover the Trust’s expenses. Under the Trust Agreement, the Trustee may delegate all or a portion of its duties to any agent and has delegated the bulk of the day-to-day responsibilities to the Trust Administrator and certain other administrative and record-keeping functions to its affiliates and other agents.

The Ether Custodian is responsible for safekeeping the ether owned by the Trust. The Ether Custodian and the Additional Ether Custodian are appointed by the Trustee. The general role and responsibilities of the Ether Custodian and the Additional Ether Custodian are further described in “The Custodians—The Ether Custodian and the Additional Ether Custodian.”

Trust Objective

The Trust seeks to reflect generally the performance of the price of ether. The Trust seeks to reflect such performance before payment of the Trust’s expenses and liabilities. The Shares are intended to constitute a simple means of making an investment similar to an investment in ether rather than by acquiring, holding and trading ether directly on a peer-to-peer or other basis or via a digital asset platform. The Shares have been designed to remove the obstacles represented by the complexities and operational burdens involved in a direct investment in ether, while at the same time having an intrinsic value that reflects, at any given time, the investment exposure to the price of ether owned by the Trust at such time, less the Trust’s expenses and liabilities. Neither the Trust, nor the Sponsor, nor the Ether Custodian, nor any other person associated with the Trust will, directly or indirectly, employ the Trust’s ether in Staking Activities. Accordingly, the Trust will not earn any form of staking rewards, or income of any kind, from Staking Activities. Foregoing potential returns from Staking Activities could cause an investment in the Shares to deviate from that which would have been obtained by purchasing and holding ether directly by virtue of giving up staking as a source of return when an investor holds the Shares. Although the Shares are not the exact equivalent of a direct investment in ether, they provide investors with an alternative method of achieving investment exposure to the price of ether through the securities market, which may be more familiar to them.

- 2 -

Table of Contents

An investment in Shares is:

Backed by ether held by the Ether Custodian on behalf of the Trust.

The Shares are backed by the assets of the Trust. The Ether Custodian keeps custody of all of the Trust’s ether, other than that which is maintained in a trading account (the “Trading Balance”) with Coinbase, Inc. (“Coinbase Inc.” or the “Prime Execution Agent”, which is an affiliate of the Ether Custodian), in accounts that are required to be segregated from the assets held by the Ether Custodian as principal and the assets of its other customers (the “Vault Balance”). The Ether Custodian keeps all of the private keys associated with the Trust’s ether held by the Ether Custodian in the Vault Balance in “cold storage”, which refers to a safeguarding method by which the private keys corresponding to the Trust’s ether are generated and stored in an offline manner using computers or devices that are not connected to the Internet, which is intended to make them more resistant to hacking.

The Trust is not required to hold any particular amount of assets at either the Ether Custodian or the Additional Ether Custodian, and the Sponsor will, in its sole discretion, determine the amounts held at either ether custodian from time to time as permitted by the Trust Agreement. As of the date of this prospectus, the Sponsor has no plans to move any of the Trust’s ether to the Additional Ether Custodian, though such plans are subject to ongoing review. The addition of the Additional Ether Custodian as an available alternative custodian reflects the Sponsor’s ongoing risk management approach, which is consistent with its overall global business practices in response to the Trust’s growing size and the Sponsor’s expanding presence in the digital asset space.

For more information, see “The Custodians—The Ether Custodian and the Additional Ether Custodian” below.

The Trust’s ether holdings and cash holdings from time to time may be held with the Prime Execution Agent in the Trading Balance in connection with creations and redemptions of Baskets, and the sale of ether to pay the Sponsor’s Fee and any other Trust expenses not assumed by the Sponsor, to the extent applicable, and in extraordinary circumstances, in connection with the liquidation of the Trust’s ether. Within the Trust’s Trading Balance, the Prime Execution Agent Agreement provides that the Trust does not have an identifiable claim to any particular ether (and cash). Instead, the Trust’s Trading Balance represents an entitlement to a pro rata share of the ether (and cash) the Prime Execution Agent holds on behalf of customers who hold similar entitlements against the Prime Execution Agent. In this way, the Trust’s Trading Balance represents an omnibus claim on the Prime Execution Agent’s ether (and cash) held on behalf of the Prime Execution Agent’s customers. The Prime Execution Agent holds the ether associated with customer entitlements across a combination of omnibus cold wallets, omnibus “hot wallets” (meaning wallets whose private keys are generated and stored online, in Internet-connected computers or devices) or in omnibus accounts in the Prime Execution Agent’s name on a trading venue (including third-party venues and the Prime Execution Agent’s own execution venue) where the Prime Execution Agent executes orders to buy and sell ether on behalf of its clients. Within such omnibus hot and cold wallets and accounts, the Prime Execution Agent has represented to the Sponsor that it keeps the majority of assets in cold wallets, to promote security, while the balance of assets is kept in hot wallets to facilitate rapid withdrawals. However, the Sponsor has no control over, and for security reasons the Prime Execution Agent does not disclose to the Sponsor, the percentage of ether that the Prime Execution Agent holds for customers holding similar entitlements as the Trust which are kept in omnibus cold wallets, as compared to omnibus hot wallets or omnibus accounts in the Prime Execution Agent’s name on a trading venue. The Prime Execution Agent has represented to the Sponsor that the percentage of assets maintained in cold versus hot storage is determined by ongoing risk analysis and market dynamics, in which the Prime Execution Agent attempts to balance anticipated liquidity needs for its customers as a class against the anticipated greater security of cold storage.

As convenient and easy to handle as any other investment in shares.

Investors may purchase and sell Shares through traditional securities brokerage accounts and can avoid the complexities of handling ether directly (e.g., managing wallets and public and private keys themselves, or interfacing with a trading platform), which some investors may not prefer or may find unfamiliar.

Listed.

The Shares are listed and traded on NASDAQ under the ticker symbol “ETHA.”

Summary Risk Factors

Risk Factors Related to Digital Assets

●

The trading prices of many digital assets, including ether, have experienced extreme volatility in recent periods and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of ether, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value.

- 3 -

Table of Contents

●

The value of the Shares is subject to a number of factors relating to the fundamental investment characteristics of ether as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Ethereum blockchain.

●

Digital assets represent a new and rapidly evolving industry, and the value of the Shares depends on the acceptance of ether.

●

Smart contracts, including those relating to decentralized finance (“DeFi”) applications, are a new technology and their ongoing development and operation may result in problems, which could reduce the demand for ether or cause a wider loss of confidence in the Ethereum network, either of which could have an adverse impact on the value of ether.

●

Changes in the governance of a digital asset network may not receive sufficient support from users and validators, which may negatively affect that digital asset network’s ability to grow and respond to challenges.

●

The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust.

Risk Factors Related to the Digital Asset Markets

●

The value of the Shares relates directly to the value of ether, the value of which may be highly volatile and subject to fluctuations due to a number of factors.

●

The Index (as defined below) has a limited performance history, the Index price could fail to track the global ether price, and a failure of the Index price could adversely affect the value of the Shares.

●

The Index price used to calculate the value of the Trust’s ether may be volatile, adversely affecting the value of the Shares.

Risk Factors Related to the Trust and the Shares

●

If the process of creation and redemption of Baskets encounters any unanticipated difficulties, the possibility for arbitrage transactions by Authorized Participants intended to keep the price of the Shares closely linked to the price of ether may not exist and, as a result, the price of the Shares may fall or otherwise diverge from NAV.

●

The liquidity of the Shares may also be affected by the withdrawal from participation of Authorized Participants or Ether Trading Counterparties.

●

Security threats to the Trust’s account at the Ether Custodian could result in the halting of Trust operations and a loss of Trust assets or damage to the reputation of the Trust, each of which could result in a reduction in the value of the Shares.

●

Ether transactions are irrevocable and stolen or incorrectly transferred ether may be irretrievable. As a result, any incorrectly executed ether transactions could adversely affect the value of the Shares.

●

If the Custodian Agreement, the Prime Execution Agent Agreement, the Authorized Participant Agreements or the Ether Trading Counterparty Agreements are terminated or the Custodians, the Prime Execution Agent, Authorized Participants or the Ether Trading Counterparties fail to provide services as required, the Trustee may operationalize the Additional Ether Custodian or may need to find and appoint replacement custodians, an execution agent, authorized participants or ether trading counterparties, which could pose a challenge to the safekeeping of the Trust’s ether, the Trust’s ability to create and redeem Shares and the Trust’s ability to continue to operate may be adversely affected.

●

The lack of full insurance and Shareholders’ limited rights of legal recourse against the Trust, the Delaware Trustee, the Sponsor, the Trust Administrator, the Cash Custodian, the Prime Execution Agent, the Ether Custodian and, if operationalized, the Additional Ether Custodian, expose the Trust and its Shareholders to the risk of loss of the Trust’s ether for which no person or entity is liable.

●

Loss of a critical banking relationship for, or the failure of a bank used by, the Prime Execution Agent could adversely impact the Trust’s ability to create or redeem Baskets, or could cause losses to the Trust.

- 4 -

Table of Contents

Risk Factors Related to the Regulation of the Trust and the Shares

●

Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of ether or the Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of ether, validation activity, digital wallets, the provision of services related to trading and custodying ether, the operation of the Ethereum network, or the digital asset markets generally.

●

If regulators subject the Trust, the Trustee, the Sponsor or Ether Trading Counterparties to regulation as a money services business (“MSB”) or money transmitter, this could result in extraordinary expenses to the Trust, the Trustee, the Sponsor or Ether Trading Counterparties and also result in decreased liquidity for the Shares.

●

Regulatory changes or interpretations could obligate an Authorized Participant, the Trust, the Trustee or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust.

●

The treatment of digital assets for U.S. federal, state and local income tax purposes is uncertain.

Emerging Growth Company Status

The Trust is an “emerging growth company,” as defined in the JOBS Act. For as long as the Trust is an emerging growth company, the Trust may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes–Oxley Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in the Trust’s periodic reports and audited financial statements in this prospectus, exemptions from the requirements of holding advisory “say-on-pay” votes on executive compensation and shareholder advisory votes on “golden parachute” compensation and exemption from any rules requiring mandatory audit firm rotation and auditor discussion and analysis and, unless otherwise determined by the SEC, any new audit rules adopted by the Public Company Accounting Oversight Board.

Under the JOBS Act, the Trust will remain an emerging growth company until the earliest of:

●

the last day of the fiscal year during which the Trust has total annual gross revenues of $1.235 billion or more;

●

the last day of the fiscal year following the fifth anniversary of this offering;

●

the date on which the Trust has, during the previous three-year period, issued more than $1 billion in non-convertible debt; or

●

the date on which the Trust is deemed to be a “large accelerated filer” (i.e., an issuer that (1) has more than $700 million in outstanding equity held by non-affiliates and (2) has been subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) for at least 12 calendar months and has filed at least one annual report on Form 10-K.)

The JOBS Act also provides that an emerging growth company can utilize the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”) for complying with new or revised accounting standards. The Trust is choosing to opt out of this extended transition period and, as a result, the Trust will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for companies that are not “emerging growth companies.” Section 107 of the JOBS Act provides that the Trust’s decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

THE OFFERING

Offering	The Shares represent units of fractional undivided beneficial interest in the net assets of the Trust.

Use of proceeds	Proceeds received by the Trust from the issuance and sale of Baskets consist of ether and cash deposits. Ether deposits are held by the Ether Custodian or Prime Execution Agent on behalf of the Trust until (i) delivered to Authorized Participants or their designated agent or client in connection with an in-kind redemption or sold in connection with a cash redemption, or (ii) sold to pay the Sponsor’s Fee and Trust expenses of liabilities not assumed by the Sponsor. Cash deposits are held by the Cash Custodian or Prime Execution Agent on behalf of the Trust until (i) transferred in connection with the purchase of ether, (ii) delivered to Authorized Participants in connection with a cash redemption of Baskets or (iii) transferred to pay the Sponsor’s Fee and Trust expenses or liabilities not assumed by the Sponsor.

NASDAQ ticker symbol	ETHA

CUSIP	46438R105

Creation and redemption	The Trust issues and redeems Baskets on a continuous basis. These transactions take place in exchange for cash or ether. Baskets are only issued or redeemed in exchange for an amount of ether or cash determined by the Trustee on each day that NASDAQ is open for regular trading. No Shares are issued unless the Ether Custodian or Prime Execution Agent has allocated to the Trust’s account the corresponding amount of ether. As of July 7, 2025, a Basket requires delivery of $771,122.04 or 302.64 ether. The amount of ether necessary for the creation of a Basket, or to be received upon redemption of a Basket, will decrease over the life of the Trust, due to the payment or accrual of fees and other expenses or liabilities payable by the Trust. Baskets may be created or redeemed only by Authorized Participants, who pay BlackRock Investments, LLC (“BRIL”), an affiliate of the Trustee that has been retained by the Trust to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Baskets (“ETF Services”), (1) a transaction fee for each order to create or redeem Baskets (the “ETF Servicing Fee”) and (2) transfer, processing and other transaction costs charged by the Ether Custodian in connection with the issuance of Baskets for such purchase order (“Custody Transaction Costs”).

	The Authorized Participants will deliver only ether or cash to create Shares and will receive only ether or cash when redeeming Shares. See “Description of the Shares and the Trust Agreement” for more details.

Net Asset Value	The net asset value of the Trust equals the total assets of the Trust, which consists solely of ether and cash, less total liabilities of the Trust, each determined by the Trustee pursuant to policies established from time to time by the Trustee or its affiliates or otherwise described herein. The methodology used to calculate an index (the “Index”) price to value ether in determining the net asset value of the Trust may not be deemed consistent with U.S. generally accepted accounting principles (“GAAP”). The Sponsor has the exclusive authority to determine the Trust’s net asset value, which it has delegated to the Trustee under the Trust Agreement. The Trustee has delegated to the Trust Administrator the responsibility to calculate the net asset value of the Trust and the NAV, based on a pricing source selected by the Trustee. In determining the Trust’s net asset value, the Trust Administrator values the ether held by the Trust based on the Index, unless the Sponsor in its sole discretion determines that the Index is unreliable. The CF Benchmarks Index shall constitute the Index, unless the CF Benchmarks Index is not available or the Sponsor in its sole discretion determines the CF Benchmarks Index is unreliable as the Index and therefore determines not to use the CF Benchmarks Index as the Index. If the CF Benchmarks Index is not available or the Sponsor determines, in its sole discretion, that the CF Benchmarks Index is unreliable (together a “Fair Value Event”), the Trust’s holdings may be fair valued on a temporary basis in accordance with the fair value policies approved by the Trustee. Additionally, the Trust Administrator will monitor for unusual prices and escalate to the Trustee if detected. If the CF Benchmarks Index is not used, the Trust will notify Shareholders in a prospectus supplement, in its periodic Exchange Act reports and/or on the Trust’s website.

	The Trust Administrator calculates the NAV of the Trust once each Business Day. The NAV for a normal trading day will be released after 4:00 p.m. Eastern Time (“ET”). Trading during the core trading session on the Exchange typically closes at 4:00 p.m. ET. However, NAVs are not officially released until after the completion of a comprehensive review of the NAV and prices utilized to determine the NAV of the Trust by the Trust Administrator. Upon the completion of the end-of-day reviews by the Trust Administrator the NAV is released to the public typically by 5:30 p.m. ET and generally no later than 8:00 p.m. ET. The period between 4:00 p.m. ET and the NAV release after 5:30 p.m. ET (or later) provides an opportunity for the Trust Administrator and the Trustee to detect, flag, investigate, and correct unusual pricing should it occur and implement a Fair Value Event, if necessary. Any such correction could adversely affect the value of the Shares. The Trust’s periodic financial statements may not utilize net asset value of the Trust to the extent the methodology used to calculate the Index is deemed not to be consistent with GAAP. The Trust’s periodic financial statements will be prepared in accordance with the Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC Topic 820”) and utilize an exchange-traded price from the Trust’s principal market for ether as of 11:59 p.m. ET on the Trust’s financial statement measurement date. The Sponsor will determine in its sole discretion the valuation sources and policies used to prepare the Trust’s financial statements in accordance with GAAP. The Trust intends to engage a third-party vendor to obtain a price from a principal market for ether, which will be determined and designated by such third-party vendor daily based on its consideration of several exchange characteristics, including oversight, and the volume and frequency of trades. Under GAAP, such a price is expected to be deemed a Level 1 input in accordance with the ASC Topic 820 because it is expected to be a quoted price in active markets for identical assets or liabilities.

Net Asset Value Calculation and Index	On each Business Day, as soon as practicable after 4:00 p.m. ET, the Trust Administrator evaluates the ether held by the Trust as reflected by the CF Benchmarks Index and determines the net asset value of the Trust and the NAV. For purposes of making these calculations, a Business Day means any day other than a day when NASDAQ is closed for regular trading.

	The CF Benchmarks Index employed by the Trust is calculated on each Business Day by aggregating the notional value of ether trading activity across major spot ether platforms. The CF Benchmarks Index is designed based on the IOSCO Principles for Financial Benchmarks and is a registered benchmark under the UK Benchmark Regulations (“BMR”). The administrator of the CF Benchmarks Index is CF Benchmarks Ltd. (the “Index Administrator”) a UK incorporated company, authorized and regulated by the Financial Conduct Authority (“FCA”) of the UK as a Benchmark Administrator, under UK BMR. The CF Benchmarks Index serves as a once-a-day benchmark rate of the U.S. dollar price of ether (USD/ETH), calculated as of 4:00 p.m. ET. The CF Benchmarks Index aggregates the trade flow of several ether platforms, during an observation window between 3:00 p.m. and 4:00 p.m. ET into the U.S. dollar price of one ether at 4:00 p.m. ET. Specifically, the CF Benchmarks Index is calculated based on the “Relevant Transactions” (as defined in “Business of the Trust – Valuation of Ether; the CF Benchmarks Index”) of all of its constituent ether platforms, which are currently Bitstamp, Coinbase, itBit, Kraken, Gemini, LMAX Digital, and Crypto.com (the “Constituent Platforms”), and which may change from time to time. The Trust is intended to provide a way for Shareholders to obtain exposure to the price of ether by investing in the Shares rather than by acquiring, holding and trading ether directly on a peer-to-peer or other basis or via a digital asset platform. An investment in the Shares is not the same as an investment directly in ether on a peer-to-peer or other basis or via a digital asset platform.

Intraday Indicative Value	In order to provide updated information relating to the Trust for use by Shareholders, the Trust intends to publish an intraday indicative value per Share (“IIV”) using the CME CF Ether-Dollar Real Time Index (“ETHUSD_RTI”). One or more major market data vendors will provide an IIV updated every 15 seconds, as calculated by the Exchange or a third-party financial data provider during NASDAQ’s regular market session of 9:30 a.m. to 4:00 p.m. ET (the “Regular Market Session”). The IIV will be calculated by using the prior day’s closing NAV as a base and updating that value during the Regular Market Session to reflect changes in the value of the Trust’s NAV during the trading day. The IIV’s dissemination during the Regular Market Session should not be viewed as an actual real-time update of the NAV, which will be calculated only once at the end of each trading day. The IIV will be widely disseminated every 15 seconds during the Regular Market Session by one or more major market data vendors. In addition, the IIV will be available through online information services.

Trust expenses

The Trust’s only ordinary recurring expense is expected to be the Sponsor’s Fee. In exchange for the Sponsor’s Fee, the Sponsor has agreed to assume the marketing and the following administrative expenses of the Trust: the fees of the Trustee, the Delaware Trustee and the Trust Administrator, the Custodians’ Fee, NASDAQ listing fees, SEC registration fees, printing and mailing costs, tax reporting fees, audit fees, license fees and expenses and up to $500,000 per annum in ordinary legal fees and expenses. The Sponsor may determine in its sole discretion to assume legal fees and expenses of the Trust in excess of the $500,000 per annum required under the Trust Agreement. To the extent that the Sponsor does not voluntarily assume such fees and expenses, they will be the responsibility of the Trust. The Sponsor will also pay the costs of the Trust’s organization and the initial sale of the Shares.

The Sponsor’s Fee is accrued daily at an annualized rate equal to 0.25% of the net asset value of the Trust and is payable at least quarterly in arrears in U.S. dollars or in-kind or any combination thereof. The Sponsor may, at its sole discretion and from time to time, waive all or a portion of the Sponsor’s Fee for stated periods of time. The Sponsor is under no obligation to waive any portion of its fees and any such waiver shall create no obligation to waive any such fees during any period not covered by the waiver. For a twelve-month period commencing on the day the Shares are initially listed on NASDAQ, the Sponsor will waive a portion of the Sponsor’s Fee so that the Sponsor’s Fee after the fee waiver will be equal to 0.12% of the net asset value of the Trust for the first $2.5 billion of the Trust’s assets.

The Trust may incur certain extraordinary, non-recurring expenses that are not assumed by the Sponsor, including but not limited to, taxes and governmental charges, any applicable brokerage commissions, financing fees, Ethereum network fees and similar transaction fees, expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of Shareholders, any indemnification of the Cash Custodian, the Ether Custodian, the Additional Ether Custodian, the Prime Execution Agent, Trust Administrator, or other agents, service providers or counterparties of the Trust and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters. Because the Trust does not have any income, it needs to sell ether to cover the Sponsor’s Fee and expenses not assumed by the Sponsor, if any. Trust expenses not assumed by the Sponsor and not included in trade execution costs paid by the Trust shall accrue daily and be payable by the Trust to the Sponsor at least quarterly in arrears. The Trust may also be subject to other liabilities (for example, as a result of litigation) that have also not been assumed by the Sponsor. The only source of funds to cover those liabilities will be sales of ether held by the Trust. Even if there are no expenses other than those assumed by the Sponsor, and there are no other liabilities of the Trust, the Trust needs to sell ether to pay the Sponsor’s Fee. The result of these sales is a decrease in the amount of ether represented by each Share.

- 9 -

Table of Contents

	To cover the Sponsor’s Fee and expenses not assumed by the Sponsor, the Sponsor or its delegate will cause the Trust (or its delegate) to convert ether into U.S. dollars at the price available through the Prime Execution Agent’s Coinbase Prime service (less applicable trading fees) through the Trading Platform which the Sponsor is able to obtain using commercially reasonable efforts. The number of ether represented by a Share will decline each time the Trust pays the Sponsor’s Fee or any Trust expenses not assumed by the Sponsor by transferring or selling ether. The quantity of ether to be sold to permit payment of the Sponsor’s Fee or Trust expenses not assumed by the Sponsor, will vary from time to time depending on the level of the Trust’s expenses and the value of ether held by the Trust. Assuming that the Trust is a grantor trust for U.S. federal income tax purposes, each delivery or sale of ether by the Trust for the payment of expenses generally will be a taxable event to Shareholders. See “U.S. Federal Income Tax Consequences.” In the event that any of the foregoing fees and expenses are incurred with respect to the Trust and other Client Accounts (as defined in “Conflicts of Interest”), the Sponsor will allocate the costs across the entities on a pro rata basis, except to the extent that certain expenses are specifically attributable to the Trust or another Client Account. The Trust expects that any trading commissions associated with block trading, if applicable, will be allocated across the relevant entities on a pro rata basis.

Staking Activities	Neither the Trust, nor the Sponsor, nor the Ether Custodian, nor any other person associated with the Trust will, directly or indirectly, engage in Staking Activities.

Incidental Rights / IR Digital Asset	From time to time, the Trust may be entitled to or come into possession of rights to acquire, or otherwise establish dominion and control over, any digital asset (for avoidance of doubt, other than ether) or other asset or right, which rights are incident to the Trust’s ownership of ether and arise without any action of the Trust, or of the Sponsor or Delaware Trustee on behalf of the Trust (“Incidental Rights”) and/or digital asset tokens, or other assets or rights, acquired by the Trust through the exercise (subject to the applicable provisions of the Trust Agreement) of any Incidental Right (“IR Digital Asset”) by virtue of its ownership of ether, generally through a fork in the Ethereum blockchain, an airdrop offered to holders of ether or other similar event.

- 10 -

Table of Contents

	With respect to a fork, airdrop or similar event, the Sponsor will cause the Trust to permanently and irrevocably abandon the Incidental Rights and IR Digital Asset and no such Incidental Right or IR Digital Asset shall be taken into account for purposes of determining the NAV of the Trust. In the event the Trust seeks to change this position, an application would need to be filed with the SEC by NASDAQ seeking approval to amend its listing rules to permit the Trust to sell Incidental Rights or IR Digital Asset and distribute the cash proceeds (net of expenses and applicable withholding taxes) to Depository Trust Company (“DTC”) or distribute the Incidental Rights or IR Digital Asset in-kind to DTC. Because the Trust will abandon any Incidental Rights and IR Digital Asset, the Trust would not receive any direct or indirect consideration for the Incidental Rights or IR Digital Asset, and thus the value of the Shares will not reflect the value of the Incidental Rights or IR Digital Asset. See “Risk Factors—Risks Related to the Trust and the Shares – A temporary or permanent “fork” could adversely affect the value of the Shares. In addition, Shareholders will not receive the benefits of any Incidental Rights and any IR Digital Asset, including any forked or airdropped assets.”

Tax Considerations	Owners of Shares will be treated, for U.S. federal income tax purposes, as if they owned a corresponding share of the assets of the Trust. They will also be viewed as if they directly received a corresponding share of any income of the Trust, or as if they had incurred a corresponding share of the expenses of the Trust. Consequently, each sale of ether by the Trust will constitute a taxable event to the Shareholders. See “U.S. Federal Income Tax Consequences—Taxation of U.S. Shareholders.”

Voting Rights	Owners of Shares do not have any voting rights, take no part in the management or control of, and have no voice in, the Trust’s operations or business. See “Description of the Shares and the Trust Agreement—Voting Rights.”

Suspension of Issuance, Transfers and Redemptions

The Trustee may, and upon the direction of the Sponsor shall, suspend the acceptance of purchase orders or the delivery or registration of transfers of Shares generally, or may, and upon the direction of the Sponsor shall, refuse a particular purchase order, delivery or registration of Shares (i) during any period when the transfer books of the Trustee are closed or (ii) at any time, if the Sponsor thinks it advisable for any reason. The Trustee may, in its sole discretion, and upon the direction of the Sponsor will, suspend the right to surrender Shares or postpone the delivery date of ether or other Trust property generally or with respect to a particular redemption order (i) during any period in which regular trading on NASDAQ is suspended or restricted, or the exchange is closed (other than scheduled holiday or weekend closings), or (ii) during a period when the Sponsor determines that delivery, disposal or evaluation of ether is not reasonably practicable (for example, as a result of an interruption in services or availability of the Prime Execution Agent, Ether Custodian, Cash Custodian, Administrator, or other service providers to the Trust, act of God, catastrophe, civil disturbance, government prohibition, war, terrorism, strike or other labor dispute, fire, force majeure, interruption in telecommunications, iShares order entry system, Internet services, or network provider services, unavailability of Fedwire, SWIFT or banks’ payment processes, significant technical failure, bug, error, disruption or fork of the Ethereum network, hacking, cybersecurity breach, or power, Internet, or Ethereum network outage, or similar event). The Trustee shall reject any purchase order or redemption order that is not in proper form. See “Description of the Shares and the Trust Agreement—Requirements for Trustee Actions.”

Authorized Participants	Baskets may be created or redeemed only by Authorized Participants. Each Authorized Participant must be a registered broker-dealer, a participant in DTC, have entered into an agreement with the Sponsor and the Trustee (the “Authorized Participant Agreement”) and be in a position to transfer cash or ether to, and take delivery of cash or ether from, the Trust Administrator through one or more accounts. The Authorized Participant Agreement provides the procedures for the creation and redemption of Baskets and for the delivery of cash or ether in connection with such creations or redemptions. As of the date of this prospectus, the Authorized Participants that are able to conduct creations and redemptions for cash are ABN AMRO Clearing USA LLC, BMO Capital Markets Corp., HRT Financial LP, Jane Street Capital, LLC, Jefferies LLC, JP Morgan Securities LLC, Macquarie Capital (USA) Inc. and Virtu Americas LLC. As of the date of this prospectus, the Sponsor and the Trustee have not entered into any agreements with Authorized Participants to facilitate creations and redemptions in-kind. Additional Authorized Participants may be added at any time, subject to the discretion of the Sponsor.

Ether Trading Counterparties	In connection with cash creations and redemptions, the Trust will engage in ether transactions for converting cash into ether (in association with purchase orders) and ether into cash (in association with redemption orders). The Trust will conduct its ether purchase and sale transactions by, in its sole discretion, choosing to trade directly with third parties (each, a “Ether Trading Counterparty”), pursuant to written agreements between such Ether Trading Counterparties and the Trust, or choosing to trade through the Prime Execution Agent through its Coinbase Prime service pursuant to the Prime Execution Agent Agreement. As of the date of this prospectus, the Ether Trading Counterparties are Cumberland DRW LLC, Flow Traders B.V., JSCT, LLC and Virtu Financial Singapore Pte. Ltd. JSCT, LLC is an affiliate of Jane Street Capital LLC and Virtu Financial Singapore Pte. Ltd. is an affiliate of Virtu Americas LLC. Each of Jane Street Capital LLC and Virtu Americas LLC is an Authorized Participant. Ether Trading Counterparties may be added at any time, subject to the discretion of the Sponsor. As of the date of this prospectus, in connection with cash creations and redemptions, the Trust is not aware of any other affiliation or material relationship between an Ether Trading Counterparty and the Authorized Participants or other service providers of the Trust in executing a transaction in ether with the Trust. In connection with cash creations and redemptions, each Ether Trading Counterparty represents to the Trust that it is acting for itself and not for another person, and is not acting as agent or at the direction of any Authorized Participant. Upon receipt of an order from an Authorized Participant to create or redeem Baskets, the Trust may obtain quotes for a price to purchase or sell ether from one or more Ether Trading Counterparties. An Ether Trading Counterparty may respond to the Trust’s request with an offer of a quote at which it is willing to sell the specified quantity of ether, or a portion thereof, in the case of a creation, or a quote at which it is willing to buy the specified quantity of ether, or a portion thereof, in the case of a redemption, as indicated in such offer. The Ether Trading Counterparties are not contractually obligated to participate in cash orders for creations or redemptions by placing any offers to buy or sell ether with the Trust. The Trust then determines, in its sole discretion, whether to utilize one of the Ether Trading Counterparties that provided a quote or to trade through the Prime Execution Agent to execute an ether trade. Once an offer is accepted, it becomes a trade that is binding on both the Trust and the Ether Trading Counterparty, subject to customary exceptions.

Clearance and settlement	The Shares will be evidenced by a global certificate that the Trust issues to DTC. The Shares are issued in book-entry form only. Transactions in Shares clear through the facilities of DTC. Investors may hold their Shares through DTC, if they are participants in DTC, or indirectly through entities that are participants in DTC.

RISK FACTORS

The Shares are speculative and involve a high degree of risk. Before making an investment decision, you should consider carefully the risks described below, as well as the other information included in this prospectus.

Risk Factors Related to Digital Assets

The trading prices of many digital assets, including ether, have experienced extreme volatility in recent periods and may continue to do so. For instance, there were steep increases in the value of certain digital assets, including ether, over the course of 2021, and multiple market observers asserted that digital assets were experiencing a “bubble.” These increases were followed by steep drawdowns throughout 2022 in digital asset trading prices, including for ether. These episodes of rapid price appreciation followed by steep drawdowns have occurred multiple times throughout ether’s history, including in 2021-2023. As of the date of this prospectus, digital asset prices have continued to fluctuate in 2025.

Extreme volatility may persist, and the value of the Shares may significantly decline in the future without recovery. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. For example, in the first half of 2022, each of Celsius Network, Voyager Digital Ltd., and Three Arrows Capital declared bankruptcy, resulting in a loss of confidence in participants of the digital asset ecosystem and negative publicity surrounding digital assets more broadly. In November 2022, FTX Trading Ltd. (“FTX”), one of the largest digital asset platforms by volume at the time, halted customer withdrawals amid rumors of the company’s liquidity issues and likely insolvency, which were subsequently corroborated by its CEO. Shortly thereafter, FTX’s CEO resigned and FTX and many of its affiliates filed for bankruptcy in the United States, while other affiliates have entered insolvency, liquidation, or similar proceedings around the globe, following which the U.S. Department of Justice brought criminal fraud and other charges, and the SEC and CFTC brought civil securities and commodities fraud charges, against certain of FTX’s and its affiliates’ senior executives, including its former CEO. In addition, several other entities in the digital asset industry filed for bankruptcy following FTX’s bankruptcy filing, such as BlockFi Inc. and Genesis Global Capital, LLC (“Genesis”). In response to these events (collectively, the “2022 Events”), the digital asset markets have experienced extreme price volatility and other entities in the digital
