ORGANIZATION [Abstract]
ORGANIZATION	1. ORGANIZATION The Franklin Ethereum Trust (the “Trust”) was formed as a Delaware statutory trust on February 8, 2024, and is governed by the provisions of an Amended and Restated Agreement and Declaration of Trust dated as of May 30, 2024 (the “Declaration of Trust”). The Trust is not registered as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”) and is not a commodity pool for purposes of the Commodity Exchange Act (“CEA”). The accompanying financial statements relate to the Trust, as registrant, and the one series that it currently offers, the Franklin Ethereum ETF (the “Fund”) presented on a combined basis. Separate, series-level financial statements are provided for the Fund in another section of this report. The Trust had no operations prior to the Fund’s launch, other than matters relating to its organization and the registration of the Fund under the Securities Act of 1933, as amended (the “Securities Act”). The Sponsor of the Trust and the Fund (the “Sponsor”) is Franklin Holdings, LLC. The Sponsor is a Delaware limited liability company formed on July 21, 2021. The Sponsor is not subject to regulation by the Commodity Futures Trading Commission (“CFTC”) as a commodity pool operator with respect to the Fund, or a commodity trading advisor with respect to the Fund. The Fund issues shares (the “Shares”), which represent units of fractional undivided beneficial interest in the Fund. The Shares of the Fund are listed on the Cboe BZX Exchange, Inc. (“Cboe BZX Exchange” or the “Exchange”). The Shares were first listed for trading and the Fund commenced operations on July 23, 2024. The Fund seeks to reflect generally the performance of the price of ether before payment of the Fund's expenses and liabilities. The Shares are intended to offer a convenient means of making an investment similar to an investment in ether relative to 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 obstacles associated with the complexities and operational burdens involved in a direct investment in ether by providing an investment with a value that reflects the price of the ether owned by the Fund at such time, less the Fund's expenses and liabilities. The Fund is not a proxy for a direct investment in ether. Rather, the Shares are intended to provide a cost-effective alternative means of obtaining investment exposure through the securities markets that is similar to an investment in ether. The Fund is a passive investment vehicle and is not a leveraged product. The Sponsor does not actively manage the ether held by the fund. BNY Mellon Asset Servicing, a division of The Bank of New York Mellon, or “BNYM,” is the Fund’s Administrator (the “Administrator”) and Transfer Agent (the “Transfer Agent”). BNYM also serves as the custodian of the Fund’s cash (the “Cash Custodian”). The Administrator is generally responsible for the day-to-day administration of the Fund, including the calculation of the Fund’s net asset value (“NAV”) per Share. The Ether Custodian is responsible for safekeeping the ether owned by the Fund. The Ether Custodian is Coinbase Custody Trust Company, LLC (“Coinbase Custody”). Coinbase Inc., an affiliate of the Ether Custodian, is the Fund’s Prime Broker. CSC Delaware Trust Company, a subsidiary of the Corporation Service Company (the “Trustee”), is the sole trustee of the Trust. Franklin Distributors, LLC is the marketing agent of the Fund (the “Marketing Agent”). The Fund issues Shares only to certain eligible financial institutions called Authorized Participants and only in one or more blocks of 50,000 Shares (“Creation Units”). Creation Units are directly redeemable only by Authorized Participants. Creation Units are issued and redeemed in exchange for cash. The Shares are listed and traded on the Exchange under the ticker symbol “EZET.” The market price of the Shares may be different than the Fund’s NAV per Share. The Fund issues Shares in Creation Units on a continuous basis at the applicable NAV per Share on the creation order date. Except when aggregated in Creation Units, the Shares are not redeemable securities. The Trust is an “emerging growth company” as that term is used in the Securities Act, and, as such, the Trust may elect to comply with certain reduced public company reporting requirements. The accompanying combined statements of assets and liabilities and combined schedules of investments at June 30, 2025 and March 31, 2025 and the combined statement of operations, combined statement of cash flows and combined statement of changes in net assets for the quarter ended June 30, 2025, have been prepared on behalf of the Trust, as registrant, combined with its one currently offered series, the Fund, and for the Fund separately (included below in a separate section of this report), and are unaudited. In the opinion of management of the Sponsor of the Trust, all adjustments (which include normal recurring adjustments) necessary to state fairly the financial position and results of operations for all periods stated have been made. In addition, interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust and the Fund's financial statements included in the Annual Report on Form 10-K for the fiscal year ended March 31, 2025. The fiscal year of the Trust and the Fund is March 31st.
