**Principal Investment Strategy**

The fund pursues its investment objective by investing only in U.S. Treasury securities, including those with floating or variable rates of interest, and cash. The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, and seeks to maintain a stable share price of $1.00.

The fund is a "government money market fund," as that term is defined in Rule 2a-7, and as such is required to invest at least 99.5% of its total assets in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities, repurchase agreements collateralized solely by cash and/or government securities, and cash. The fund typically invests exclusively in U.S. Treasury securities.

By investing exclusively in U.S. Treasury securities, income paid by the fund generally will be exempt from state and local taxes. Because rules regarding the state and local taxation of dividend income can differ from state to state, investors are urged to consult their tax advisers about the taxation of the fund's dividend income in their state and locality.

**Principal Risks**

An investment in the fund is not a bank account or a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. BNY Mellon Investment Adviser, Inc. and its affiliates are not required to reimburse the fund for losses, and you should not expect that BNY Mellon Investment Adviser, Inc. or its affiliates will provide financial support to the fund at any time, including during periods of market stress. The following are the principal risks that could reduce the fund's income level and/or share price:

· *Interest rate risk:* This risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected rise in interest rates could impair the fund's ability to maintain a stable net asset value. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation and changes in general economic conditions. It is difficult to predict the pace at which central banks or monetary authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such changes. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the fund, depending on the interest rate environment or other circumstances.

· *Liquidity risk:* When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially impairing the fund's ability to maintain a stable net asset value.

· *U.S. Treasury securities risk:* A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate.

· *Market risk:* The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments. Events such as war, acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments. Recent examples include pandemic risks related to COVID-19 and aggressive measures taken world-wide in response by governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations, and by businesses, including changes to operations and reducing staff.

**Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Institutional shares from year to year. The table shows the average annual total returns of the fund's Institutional shares over time. The fund's past performance is not necessarily an indication of how the fund will perform in the future. More recent performance information may be available at www.dreyfus.com.

The historical performance of the fund's Institutional shares, which are not offered in this prospectus, is shown in the bar chart and table since Token-Enabled shares are new and past performance information is not available for Token-Enabled shares as of the date of this prospectus. Each share class is invested in the same portfolio of securities, and the annual returns would have differed only to the extent that the classes have different expenses. Accordingly, although Token-Enabled shares are estimated to

have a comparable total annual expense ratio to that of Institutional shares, to the extent Token-Enabled shares were to have a higher total annual expense ratio than Institutional shares, the performance shown for Token-Enabled shares would be lower.

**Portfolio Management**

The fund's investment adviser is BNY Mellon Investment Adviser, Inc. (BNYIA). BNYIA has engaged its affiliate, Dreyfus, a division of Mellon Investments Corporation, to serve as the fund's sub-adviser.

**Purchase and Sale of Fund Shares**

This prospectus offers Token-Enabled shares.

The fund's Token-Enabled shares are designed generally for institutional investors, acting for themselves or in a fiduciary, advisory, agency, brokerage, custodial or similar capacity. Token-Enabled shares of the fund also may be purchased directly by individuals. **Investors are required to purchase Token-Enabled shares through The Bank of New York Mellon, an affiliate of BNYIA, on The Bank of New York Mellon's platform. For information on how to purchase Token-Enabled shares, please contact your BNY representative.** In general, the fund's minimum initial investment for Token-Enabled shares is $10 million with no minimum subsequent investment, unless: (a) the investor has invested at least $10 million in the aggregate among the fund and any of the Cash Management Funds, the Preferred Funds or Dreyfus Treasury and Agency Liquidity Money Market Fund; or (b) the investor has, in the opinion of BNY Institutional Services, adequate intent and availability of assets to reach a future aggregate level of investment of $10 million in such funds. You may sell (redeem) your shares on any business day by contacting your BNY representative.

The fund's transfer agent maintains the official books and records of ownership of Token-Enabled shares, with such ownership reflected as an omnibus account for The Bank of New York Mellon (The Bank of New York Mellon Omnibus Account). The Bank of New York Mellon will maintain the share ownership records of its clients using its traditional books and records methods, and also will mirror such share ownership via a blockchain system. Assets are represented on the blockchain through "tokens," which are a digital representation of an asset and are built into the blockchain. Clients of The Bank of New York Mellon will not have access to ownership records, and will not be able to transact, directly on the blockchain.

**Tax Information**

The fund's distributions are taxable as ordinary income or capital gains, except when your investment is through a U.S. tax-advantaged investment plan (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase shares through a broker-dealer or other financial intermediary (such as a bank), the fund's distributor and its related companies may pay the intermediary for the sale of fund shares and related services. To the extent that the intermediary may receive lesser or no payments in connection with the sale of other investments, the payments from the fund's distributor and its related companies may create a potential conflict of interest by influencing the broker-dealer or other intermediary and your

financial representative to recommend the fund over the other investments. This potential conflict of interest may be addressed by policies, procedures or practices adopted by the financial intermediary. As there may be many different policies, procedures or practices adopted by different intermediaries to address the manner in which compensation is earned through the sale of investments or the provision of related services, the compensation rates and other payment arrangements that may apply to a financial intermediary and its representatives may vary by intermediary. Ask your financial representative or visit your financial intermediary's website for more information.

*This prospectus does not constitute an offer or solicitation in any state or jurisdiction in which, or to any person to whom, such offering or solicitation may not lawfully be made.*
