Grayscale Operating, LLC (“GSO” d/b/a Grayscale Investments) is the parent holding company of Grayscale Advisors, LLC (“GSA”), an SEC-registered investment adviser, as well Grayscale Securities, LLC (“GSS”), an SEC-registered broker/dealer and member of FINRA, and Grayscale Investments Sponsors, LLC ("GSIS", together with GSO, GSS, and GSA, "Grayscale" or “Grayscale Investments”). GSIS is not registered as an investment adviser under the Investment Advisers Act of 1940 and none of the investment products (“Products”) sponsored or managed by GSIS are registered under the Investment Company Act of 1940.

Private placement securities are speculative, illiquid, and entail a high level of risk, including the risk that an investor could lose their entire investment. The Products are not suitable for any investor that cannot afford loss of the entire investment.

The Space and Time protocol was relatively recently conceived and the Space and Time protocol or its Proof-of-SQL mechanisms may not function as intended, which could have an adverse impact on the value of SXT and an investment in the Shares.

Carefully consider investment objectives, risk factors, fees and expenses before investing. This and other information can be found in each Product’s private placement memorandum, which may be obtained from Grayscale and, for each Product that is an SEC reporting company, the SEC’s website, or for each Product that reports under the OTC Markets Alternative Reporting Standards, the OTC Markets website. Reports prepared in accordance with the OTC Markets Alternative Reporting Standards are not prepared in accordance with SEC requirements and may not contain all information that is useful for an informed investment decision. Read these documents carefully before investing.

The shares of each Product are intended to reflect the price of the digital asset(s) held by such Product (based on digital asset(s) per share), less such Product’s expenses and other liabilities. Because each Product does not currently operate a redemption program, there can be no assurance that the value of such Product’s shares will reflect the value of the assets held by such Product, less such Product’s expenses and other liabilities, and the shares of such Product, if traded on any secondary market, may trade at a substantial premium over, or a substantial discount to, the value of the assets held by such Product, less such Product’s expenses and other liabilities, and such Product may be unable to meet its investment objective.

If the shares trade at a premium, investors who purchase shares on the secondary market will pay more for their shares than investors who purchase shares directly from authorized participants. In contrast, if the shares trade on the secondary market at a discount, investors who purchase shares directly from authorized participants will pay more for their shares than investors who purchase shares on the secondary market.

Grayscale intends to attempt to have shares of its Products quoted on a secondary market. However, there is no guarantee that we will be successful. Although the shares of certain products have been approved for trading on a secondary market, investors in the new products should not assume that the shares will ever obtain such an approval due to a variety of factors, including questions regulators, such as the SEC, FINRA, or other regulatory bodies may have regarding such products. As a result, shareholders of such products should be prepared to bear the risk of investment in the shares indefinitely.

The shares of each Product are not registered under the Securities Act of 1933, the Securities Exchange Act of 1934 (except for Products that are SEC reporting companies), the Investment Company Act of 1940, or any state securities laws. The Products are offered in private placements pursuant to the exemption from registration provided by Rule 506(c) under Regulation D of the Securities Act of 1933 and are only available to accredited investors. As a result, the shares of each Product are restricted and subject to significant limitations on resales and transfers. Potential investors in any Product should carefully consider the long-term nature of an investment in that Product prior to making an investment decision. The shares of certain Products are also publicly quoted on OTC Markets and shares that have become unrestricted in accordance with the rules and regulations of the SEC may be bought and sold throughout the day through any brokerage account.

Grayscale's private placements are only available to Accredited Investors as defined in rule 501(a) of Regulation D under the Securities Act of 1933, as amended. Most individuals are not Accredited Investors. An individual must earn more than $200,000 a year (or $300,000 per year with a spouse or spousal equivalent), have a net worth over $1 million either alone or together with a spouse or spousal equivalent, excluding their primary residence, or hold in good standing their Series 7, Series 65, or Series 82 professional certifications. Entities must have $5 million in liquid assets or all beneficial owners must be Accredited Investors.

Digital Asset Risk Disclosures

Extreme volatility of trading prices that many digital assets have experienced in recent periods and may continue to experience, could have a material adverse effect on the value of the Product and the shares of each Product could lose all or substantially all of their value.

Digital assets represent a new and rapidly evolving industry. The value of the Product shares depends on the acceptance of the digital assets, the capabilities and development of blockchain technologies and the fundamental investment characteristics of the digital asset.

Digital asset networks are developed by a diverse set of contributors and the perception that certain high-profile contributors will no longer contribute to the network could have an adverse effect on the market price of the related digital asset.

Digital assets may have concentrated ownership and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets.

The value of the Product shares relates directly to the value of the underlying digital asset, the value of which may be highly volatile and subject to fluctuations due to a number of factors.

A substantial direct investment in digital assets may require expensive and sometimes complicated arrangements in connection with the acquisition, security and safekeeping of the digital asset and may involve the payment of substantial acquisition fees from third party facilitators through cash payments of U.S. dollars. Because the value of the Shares is correlated with the value of digital asset(s) held by the Product, it is important to understand the investment attributes of, and the market for, the underlying digital asset. Please consult with your financial professional.

The Products rely on third party service providers to perform certain functions essential to the affairs of the Product and the replacement of such service providers could pose a challenge to the safekeeping of the digital asset and to the operations of the Products.

Grayscale does not store, hold, or maintain custody of any Product’s digital assets, but instead has entered into a Custodian Agreement on behalf of each Product with a third party custodian to facilitate the security of each Product’s digital assets. The custodian controls and secures each Product’s digital asset account, a segregated custody account to store private keys, which allow for the transfer of ownership or control of the digital asset, on each Product’s behalf. If the custodian resigns or is removed by Grayscale or otherwise, without replacement, it could trigger early termination of such Product.
