Investors should consider the investment objectives, risks, charges and expenses carefully before investing.

Read the prospectus or summary prospectus carefully before investing.

Grayscale Ethereum Covered Call ETF (the “Fund” or “ETCO”) will not invest in digital assets directly. The Fund also will not invest in initial coin offerings. The Fund will, however, have indirect exposure to digital assets by virtue of its investments in exchange-traded vehicles (such as exchange-traded products) that hold digital assets as investments or its investments in derivatives to synthetically seek to track the price of such exchange-traded products. Because the Fund will not invest directly in any digital assets, it may not track price movements of any digital assets. The Fund does not invest in, or seek direct exposure to, the current “spot” or cash price of ether. Investors seeking direct exposure to the price of ether should consider an investment other than the Fund.

Investing involves risk and possible loss of principal. There is no guarantee the investment strategy will be successful. The Fund is considered to be non-diversified. The Fund is actively managed and its performance reflects the investment decisions that the Adviser makes for the Fund.

Derivative Instruments. The Fund will invest in options, a type of derivative instrument. Derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses for the Fund. In addition, the prices of the derivative instruments and the prices of underlying securities, interest rates or currencies they are designed to reflect may not move together as expected. Derivatives are usually traded on margin, which may subject the Fund to margin calls. Margin calls may force the Fund to liquidate assets. Virtual currency derivatives may experience significant price volatility and the initial margin for virtual currency derivatives may be set as a percentage of the value of a particular contract, which means that margin requirements for long positions can increase if the price of the contract rises. In addition, some futures commission merchants may pose restrictions on customer trading activity in virtual currency derivatives, such as requiring additional margin, imposing position limits, prohibiting naked shorting or prohibiting give-in transactions. The rules of certain designated contract markets impose trading halts that may restrict the issuer’s ability to exit a position during a period of high volatility.

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

Covered Call Option Writing Risk. By writing covered call options in return for the receipt of premiums, the Fund will give up the opportunity to benefit from potential increases in the value of the security above the exercise prices of such options but will continue to bear the risk of declines in the value of the underlying security. The premiums received from the options may not be sufficient to offset any losses sustained from the volatility of the underlying stocks over time. In addition, the Fund’s ability to sell the securities underlying the options will be limited while the options are in effect unless the Fund cancels out the option positions through the purchase of offsetting identical options prior to the expiration of the written options. Exchanges may suspend the trading of options in volatile markets. If trading is suspended, the Fund may be unable to write options at times that may be desirable or advantageous to do so.

Digital Assets Risk. Digital assets, such as ether, are assets designed to act as a medium of exchange, though some arguably have not achieved that purpose. Digital assets are an emerging asset class. Digital assets generally operate without a central authority (such as a bank) and are not backed by any government. Digital assets are not legal tender. Federal, state and/or foreign governments may restrict the use and exchange of digital assets, and regulation in the United States is still developing.

Ether Investment Risk. Ether is a relatively new innovation and the market for Ether is subject to rapid price swings, changes and uncertainty. Ether is not legal tender and generally operates without central authority (such as a bank) and is not backed by any government. The prices of digital assets, including Ether, have historically been highly volatile. The value of the Fund’s investments in digital asset related investments, including Ether, and therefore the value of an investment in the Fund, could decline significantly and without warning, including to zero. If you are not prepared to accept significant and unexpected changes in the value of the Fund and the possibility that you could lose your entire investment in the Fund you should not invest in the Fund.

Ethereum ETPs Investment Risk. The Fund intends to obtain investment exposure to Ether, indirectly via synthetic exposure to Ethereum ETPs through derivatives. The price of Ethereum ETPs shares may not directly correspond to the price of any digital currency and are highly volatile. The shares of Ethereum ETPs are not registered under the 1940 Act, or any state securities laws, and therefore such an investment will not benefit from the protections and restrictions of such laws.

Of the Ethereum ETPs, Grayscale Ethereum Trust ETF (“ETHE”) and Grayscale Ethereum Mini Trust ETF (“ETH”) are sponsored by an affiliate of the Fund’s Adviser that receives a fee in exchange for assuming certain administrative and marketing expenses of ETHE and ETH. The shares of ETHE and ETH are not registered under the 1940 Act, or any state securities laws, and therefore such an investment will not benefit from the protections and restrictions of such laws. While the Fund does not invest directly in ETHE and ETH, the Fund’s strategy may result in additional purchases of shares of ETHE and ETH by options holders, which will benefit the Adviser and its affiliate in terms of fee being received on these products.

Ethereum ETP Options Risk. The market for Ethereum ETP Options may be less developed, and potentially less liquid and more volatile, than more established options markets. There can be no assurance that this market will grow. The price of Ethereum ETP Options is based on a number of factors, including the supply of and the demand of options contracts on Ethereum ETPs.

Liquidity Risk. The market for Ethereum ETP options is still developing and may be subject to a period of illiquidity.

Subsidiary Investment Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act; therefore, the Fund will not receive all of the protections offered to investors in registered investment companies. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as intended, which may negatively affect the Fund and its shareholders.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition of an issuer of those securities may cause the value of the securities to decline.

New Fund Risk. The Fund is a recently organized investment company with no operating history.

The Fund is distributed by Foreside Fund Services, LLC and Grayscale Advisors, LLC (“GSA”) is the adviser. Foreside is not related to GSA or its affiliates.
