Related Party Transactions [Abstract]
Related Parties	6. Related Parties The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of September 30, 2025: DCG, GSO, GSIS and Grayscale Securities. As of September 30, 2025 and 2024, 47,588 and 90,876, Shares of the Trust were held by related parties of the Trust, respectively. Genesis Global Trading, Inc. filed a certificate of dissolution in August 2024, and has therefore been removed from the list of related parties. In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 2.5% of the aggregate value of the Trust’s assets, less its liabilities (which include any accrued but unpaid expenses up to, but excluding, the date of calculation), as calculated and published by the Sponsor or its delegates in the manner set forth in the Trust Agreement (the “Sponsor’s Fee”). The Sponsor’s Fee accrues daily in U.S. dollars and is payable in XLM, monthly in arrears. The amount of XLM payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of XLM used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of XLM is determined by reference to the Digital Asset Trading Platform Market that the Trust considers its principal market as of 4:00 p.m., New York time, on each valuation date. The Trust held no Incidental Rights or IR Virtual Currency as of September 30, 2025 and 2024. No Incidental Rights or IR Virtual Currencies have been distributed in payment of the Sponsor’s Fee during the years ended September 30, 2025, 2024 and 2023. As partial consideration for receipt of the Sponsor’s Fee, the Sponsor is obligated under the Trust Agreement to assume and pay all fees and other expenses incurred by the Trust in the ordinary course of its affairs, excluding taxes, but including marketing fees; administrator fees, if any; custodian fees; transfer agent fees; trustee fees; the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including customary legal, marketing and audit fees and expenses) in an amount up to $600,000 in any given fiscal year; ordinary course legal fees and expenses; audit fees; regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act or the Exchange Act; printing and mailing costs; the costs of maintaining the Trust’s website and applicable license fees (together, the “Sponsor-paid Expenses”). The Trust may incur certain extraordinary, non-recurring expenses that are not Sponsor-paid Expenses, including, but not limited to, taxes and governmental charges, 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 (including in connection with any Incidental Rights and any IR Virtual Currency), any indemnification of the Custodian or other agents, service providers or counterparties of the Trust, the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including legal, marketing and audit fees and expenses) to the extent exceeding $600,000 in any given fiscal year and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively “Additional Trust Expenses”). In such circumstances, the Sponsor or its delegate (i) will instruct the Custodian to withdraw from the Digital Asset Account XLM, Incidental Rights and/or IR Virtual Currency in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (ii) may either (x) cause the Trust (or its delegate) to convert such XLM, Incidental Rights and/or IR Virtual Currency into U.S. dollars or other fiat currencies at the Actual Exchange Rate or (y) when the Sponsor incurs such expenses on behalf of the Trust, cause the Trust (or its delegate) to deliver such XLM, Incidental Rights and/or IR Virtual Currency in kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses. For the years ended September 30, 2025, 2024 and 2023, the Trust incurred Sponsor’s Fees of $922,166, $233,078, and $186,863, respectively. As of September 30, 2025 and 2024, there were no accrued and unpaid Sponsor’s Fees. In addition, the Sponsor may pay Additional Trust Expenses on behalf of the Trust, which are reimbursable by the Trust to the Sponsor. For the years ended September 30, 2025, 2024 and 2023, the Sponsor did not pay any Additional Trust Expenses on behalf of the Trust. On March 2, 2022, the board of the Sponsor approved the purchase by DCG, the indirect parent company of the Sponsor, of up to $200 million worth of Shares of the Trust. Subsequently, DCG authorized such purchase. The Share purchase authorization does not obligate DCG to acquire any specific number of Shares in any period, and may be expanded, extended, modified, or discontinued at any time. From March 2, 2022 through September 30, 2025, DCG had not purchased any Shares of the Trust under this authorization.
