Subsequent Events [Text Block]	NOTE 16. SUBSEQUENT EVENTS The Company has evaluated all subsequent events through October 29, 2026, the filing date of this Form 10-Q with the SEC, to ensure that this filing includes appropriate disclosure of events both recognized in the unaudited condensed financial statements as of September 30, 2026, and events which occurred subsequently but were not recognized in the unaudited condensed financial statements. *At-the-Market Offering Program* Subsequent to September 30, 2026 and through October 26, 2026, the Company sold an aggregate of 15,801,547 shares of Common Stock under the ATM Program for aggregate gross proceeds of approximately $46.8 million and net proceeds of approximately $45.9 million, after deducting sales agent commissions and other offering costs. As of October 26, 2026, approximately $36.4 million of Common Stock remained available for issuance under the ATM Program. See Note 8, “Financing Activities,” for additional information regarding the ATM Program. *Exercise of January 2026 Pre-Funded Warrant* On October 13, 2026, Tether exercised a portion of its January 2026 Pre-Funded Warrant on a cashless basis pursuant to Section 2(c) thereof with respect to 5,743,762 shares of Common Stock. In accordance with the net exercise provisions of the warrant, 197,652 shares were withheld in payment of the aggregate exercise price, resulting in a net issuance of 5,546,110 shares of Common Stock to Tether. Following the exercise, Tether’s January 2026 Pre-Funded Warrant remained exercisable for 38,006,238 shares of Common Stock, subject to the beneficial ownership limitation and the exercisability schedule described in Note 8, “Financing Activities.” *CEO Performance-Based Restricted Stock Units* The performance period for the VWAP RSUs described in Note 12, "Stock-Based Compensation," commenced on October 16, 2026. On October 16, 2026, the Common Stock attained a ten-trading-day VWAP (as defined in the award agreement) of at least $2.55 per share and, accordingly, the first two VWAP RSU tranches, representing an aggregate of 5,148,537 RSUs, were earned. The Compensation Committee of the Board certified the attainment on October 22, 2026. Earned RSUs vest in equal quarterly installments over the eight fiscal quarters following attainment, subject to the 13-month cliff measured from the January 16, 2026 vesting start date and to continued service. Accordingly, no earned RSUs will vest or be settled in shares of Common Stock before February 16, 2027. The attainment is a nonrecognized subsequent event and had no effect on the Company's financial position or results of operations as of and for the periods ended September 30, 2026. The attainment did not change the grant-date fair value of the VWAP RSUs. Unrecognized compensation cost related to the earned tranches was approximately $6.2 million as of September 30, 2026, and the attainment shortens the period over which that cost will be recognized. *Decline in Market Price of SKY* Subsequent to September 30, 2026, the market price of SKY declined. The price of SKY in the Company’s principal market, Coinbase Exchange, was $0.06761 per token as of midnight UTC on October 26, 2026, compared to $0.07764 per token as of September 30, 2026, a decrease of approximately 13%.
