This
EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of the 15 day of March, 2021 (the
“Effective Date”), by and between RocketFuel Blockchain, Inc.,
a Nevada corporation (“Employer”), and Gert Funk (“Executive”),
and is made with reference to the following facts:

 

A.
Employer desires to employ Executive as its Chairman in order to have the benefit of Executive’s special knowledge, experience,
reputation and abilities in the industry in which Employer is engaged; and

 

B.
Executive has advised Employer of his willingness to act as Chairman and to utilize his special knowledge, experience, reputation
and abilities for the benefit of Employer and its members under the terms and conditions provided herein.

THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration had and received,
the parties hereto hereby agree as follows:

 

1.

policies, directions, and restrictions as the Board may from time to time establish for senior executive officers of the Company.

 

    	 

    	 	 	 

    

 

3.

and the Company. Specifically, Employee’s employment will be on an “at will” basis and can be terminated by
either Executive or Employer for any reason without prior written notice to the other party. There are no express or implied
agreements contrary to the foregoing and no one other than the Chief Executive Officer has any authority to enter into an employment
agreement for a specified period of time or to make any agreement that is contrary to the foregoing. Any such agreement by the
Chief Executive Officer must be in writing and fully executed by both Executive and the Chief Executive Officer.

 

4.
Compensation and Other Benefits. As compensation in full for the services to be rendered by Executive hereunder, Employer
shall pay, and Executive shall accept, the following compensation:

makes available to its executive officers, including without limitation vacation and paid other paid leave, group hospitalization,
group disability policies, medical and dental plans and group life insurance plans, and pension, 401(k) and similar plans.

 

(b)
Stock Options. Subject to the commencement of Executive’s employment hereunder, the Board has approved the grant
to Executive as of the Effective Date of an option (an “Option”) to purchase 500,000 shares of Employer’s
common stock, par value $0.001 per share. The Option shall (i) be an incentive stock option, (ii) have an exercise price equal
to the fair market value per share of Employer’s common stock on the Effective Date, as determined by an independent valuation
by a qualified appraiser, (iii) have a term of 10 years following the Effective Date, (iv) vest and become exercisable as to 1/48th

costs) of any initial coin offering (ICO), initial exchange offering (IEO), token generation event (TGE) or similar financing
(a “Token Transaction”) completed on or before the date that is 12 months after the formal acceptance by the
Board of a proposal for a Token Transaction (start date, milestones, responsibilities) sourced by Executive. In the event the
Board decides to cancel the Token Transaction, Executive and the Board shall agree upon a mutually acceptable bonus structure
in lieu of the foregoing.

 

    	 

    	 	 	 

    

 

5.
Certain Business Expenses. Executive is authorized to incur ordinary, necessary and reasonable expenses in the course
of performing his duties and obligations with respect to the business of Employer, including expenses for entertainment, travel
and similar items; provided that Employer shall at all times comply with the Company’s policies regarding expense
reimbursements. Employer shall promptly reimburse Executive for all such expenses paid by Executive on behalf of Employer upon
the presentation by Executive of an itemized request for reimbursement of expenditures supported by documentation on Employer-approved
forms.

 

6.
Proprietary Rights and Confidentiality. Executive has entered into an Executive Invention Assignment and Confidentiality
Agreement, which agreement, attached hereto as Annex A, is hereby incorporated herein in its entirety.

 

7.
Executive Representations and Warranties. Executive warrants and represents to and covenants with Employer that:

 

(a)
The execution, delivery and performance of the Agreement by Executive do not conflict with or violate any provision of or constitute
a default under any agreement, judgment, award or decree to which Executive is a party or by which Executive is bound.

 

(b)
Executive has had full opportunity to review Employer’s periodic filings with the Securities and Exchange Commission (the
“SEC”) and additional information regarding the business and financial condition of Employer. Executive believes
he has received all the information he considers necessary or appropriate for deciding whether to enter into this Agreement and
to receive as compensation the Option, the Option Shares, the Warrant and the shares of common stock issuable upon exercise of
the Warrants (together, the “Securities”). Executive further represents that he has had an opportunity to ask
questions and receive answers from Employer regarding the business, properties, prospects and financial condition of Employer.
Executive has had full opportunity to discuss this information with Executive’s legal and financial advisers prior to execution
of this Agreement.

 

(c)
Executive acknowledges that the Securities are being issued by Employer pursuant to an exemption from registration under the Securities
Act of 1933 (the “Securities Act”). Executive understands that the Securities are characterized as “restricted
securities” under the Securities Act and that under such laws and applicable regulations such securities may be resold without
registration under the Securities Act only in certain limited circumstances. In this connection, Executive represents that he
is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities
Act.

 

(d)
The Securities will be acquired by Executive for investment for Executive’s own account, not as a nominee or agent, and
not with a view to the resale or distribution of any part thereof, and Executive has no present intention of selling, granting
any participation in, or otherwise distributing the same. Executive does not have any contract, undertaking, agreement or arrangement
with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities.

 

    	 

    	 	 	 

    

 

(e)
Executive is purchasing the Securities as principal for his own account and not for the benefit of any other person.

 

(f)
Executive is an accredited investor as defined in Regulation D under the Securities Act.

 

8.
Termination Prior to Expiration of Term. Prior to the expiration of the Term, Executive’s employment hereunder may
be terminated by Employer for Cause upon five days’ written notice to Executive that describes such Cause in detail. Executive
shall have no right to receive the compensation and other benefits set forth in this Section 4 for any period commencing after
the date of termination for cause. For these purposes, the term “Cause” as used in this Agreement shall have
the meaning set forth in Section 2 of the Plan.

 

9.
Death During Employment. If Executive dies during the Term, Employer shall pay to the estate of Executive the compensation
which would otherwise be payable to Executive up to the end of the month in which his death occurs, and Employer shall have no
further obligation under this Agreement.

 

10.
Covenant Not to Compete. In the event that Employer terminates Executive’s employment hereunder for Cause, or in
the event that Executive voluntarily terminates his employment hereunder, Executive shall, in connection with any sale of all
or substantially all of his equity interests in the Company resulting from such termination, be prohibited from carrying on or
participating in a business similar to that of Employer for a period of two years following such termination, unless Executive
has express prior written consent from Employer’s Board, which approval shall not be unreasonably withheld.

 

11.

effective, and any applicable time period shall commence, when (a) delivered to the following address by hand or by a nationally

Agreement.

 

20.
Waiver. No amendment or waiver of any provision of this Agreement shall in any event be effective, unless the same shall

and for the specific purpose for which given. The failure of any party to insist, in any one or more instances, upon performance

interests, assets or business by dissolution, merger, consolidation, transfer of assets, or otherwise, or (b) any direct or indirect
subsidiary of Employer or of any such successor referred in (a) hereof. Nothing in this Agreement, expressed or implied, is intended

ROCKETFUEL
BLOCKCHAIN, INC.

 

WARRANT
TO PURCHASE COMMON STOCK

 

	Warrant
    No. W-3	Original
Issue Date: March 18, 2021

 

RocketFuel
Blockchain, Inc., a Nevada corporation (the
“Company”), hereby certifies that, for value received, Peter M. Jensen
or his permitted registered assigns (the “Holder”), is entitled to purchase from the Company up
to a total of 265,982 shares of common stock, $0.001 par value per share (the “Common Stock”), of the Company
(each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise
price per share equal to $1.00 (as adjusted from time to time as provided in Section 9 herein, the “Exercise Price”),
at any time and from time to time on or after the Original Issue Date and through and including 5:00 P.M., Los Angeles, California
time, on the 10th anniversary of the Original Issue Date (the “Expiration Date”), subject to the following
terms and conditions:

 

1.
Definitions. In addition to the terms defined elsewhere in this warrant (this “Warrant”), capitalized
terms that are not otherwise defined herein have the meanings given to such terms in the Executive Employment Agreement dated
as of September 15, 2020 between the Company and the Holder (the “Agreement”).

 

2.
Registration of Warrants. The Company shall register this Warrant, upon records to be maintained by the Company for that
purpose (the “Warrant Register”), in the name of the record Holder (which shall include the initial Holder
or, as the case may be, any registered assignee to which this Warrant is permissibly assigned hereunder) from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise
hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

 

    	 

    	 	 	 

    

 

3.
Registration of Transfers. Subject to the restrictions on transfer set forth in Section 7 of the Agreement and compliance
with all applicable securities laws, the Company shall register the transfer of all or any portion of this Warrant in the Warrant
Register, upon (i) surrender of this Warrant, with the Form of Assignment attached as Schedule 2 hereto duly completed
and signed, to the Company at its address specified in the Agreement and (ii) (x) delivery, at the request of the Company, of
an opinion of counsel reasonably satisfactory to the Company to the effect that the transfer of such portion of this Warrant may
be made pursuant to an available exemption from the registration requirements of the Securities Act and all applicable state securities
or blue sky laws and (y) delivery by the transferee of a written statement to the Company certifying that the transferee is an
“accredited investor” as defined in Rule 501(a) under the Securities Act and making the representations and certifications
set forth in Section 7 of the Agreement, to the Company at its address specified in the Agreement. Upon any such registration
or transfer, a new warrant to purchase Common Stock in substantially the form of this Warrant (any such new warrant, a “New
Warrant”) evidencing the portion of this Warrant so transferred shall be issued to the transferee, and a New Warrant
evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance
of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations
of a Holder of a Warrant. Notwithstanding the foregoing, this Warrant may not be transferred in increments of less than 10,000
Warrant Shares unless the entire remaining Warrant is transferred.

 

4.
Exercise and Duration of Warrants.

 

(a)
All or any part of this Warrant shall be exercisable, in whole or in part, by the registered Holder at any time and from time
to time on or after the Original Issue Date and through and including 5:00 P.M., Los Angeles, California time, on the Expiration
Date. At 5:00 P.M., Los Angeles, California time, on the Expiration Date, the portion of this Warrant not exercised prior thereto
shall be and become void and of no value and this Warrant shall be terminated and no longer outstanding.

 

(b)
The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule
1 hereto (the “Exercise Notice”), appropriately completed and duly signed and (ii) payment in immediately
available funds of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised, and the date
such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise
Date.” The delivery by (or on behalf of) the Holder of the Exercise Notice and the applicable Exercise Price as provided
above shall constitute the Holder’s certification to the Company that its representations contained in Section 7 of the
Agreement are true and correct as of the Exercise Date as if remade in their entirety (or, in the case of any transferee Holder
that is not a party to the Agreement, such transferee Holder’s certification to the Company that such representations are
true and correct as to such assignee Holder as of the Exercise Date). The Holder shall not be required to deliver the original
Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice shall have the same effect as
cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant
Shares.

 

    	2

    	 	 	 

    

 

5.
Delivery of Warrant Shares.

 

(a)
Upon exercise of this Warrant, the Company shall promptly (but in no event later than three Trading Days after the Exercise Date)
issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as
the Holder may designate (provided that if the Holder directs the Company to register the Warrant Shares in a name other than
that of the Holder, it shall deliver to the Company on the Exercise Date an opinion of counsel reasonably satisfactory to the
Company to the effect that the issuance of such Warrant Shares in such other name may be made pursuant to an available exemption
from the registration requirements of the Securities Act and all applicable state securities or blue sky laws), a certificate
for the Warrant Shares issuable upon such exercise, free of restrictive legends, unless a registration statement covering the
resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective or the Warrant Shares
are not freely transferable without volume restrictions pursuant to Rule 144 under the Securities Act. The Holder, or any Person
permissibly so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of such
Warrant Shares as of the Exercise Date. If the Warrant Shares are to be issued free of all restrictive legends, the Company shall,
upon the written request of the Holder, use its commercially reasonable efforts to deliver, or cause to be delivered, Warrant
Shares hereunder electronically through The Depository Trust Company or another established clearing corporation performing similar
functions, if available; provided, that, the Company may, but will not be required to, change its transfer agent if
its current transfer agent cannot deliver Warrant Shares electronically through such a clearing corporation.

 

(b)
If by the close of the third Trading Day after delivery of a properly completed Exercise Notice (and any other documents required
pursuant to Section 5(a)), the Company fails to deliver to the Holder the required number of Warrant Shares in the manner required
pursuant to Section 5(a), and if on or after the Trading Day immediately following such third Trading Day and prior to the receipt
of such Warrant Shares, the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall, within three Trading Days after the Holder’s request and in the Holder’s sole discretion,
either (1) pay in cash to the Holder an amount equal to the Holder’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s
obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate or (2) promptly honor its obligation
to deliver to the Holder Warrant Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price
over the product of (A) such number of Warrant Shares, times (B) the Closing Sales Price (as defined below) on the date of receipt
of a properly completed Exercise Notice.

 

(c)
To the extent permitted by law, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms
hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or
consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same,
or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other
Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective
of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance
of Warrant Shares. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder,
at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the
Company’s failure to timely deliver Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

 

    	3

    	 	 	 

    

 

6.
Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant
shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense
in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided,
however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the
registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof.
The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant
or receiving Warrant Shares upon exercise hereof.

 

7.
Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be
issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant,
but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction (in such case) and,
in each case, a customary and reasonable indemnity (which shall not include a surety bond), if requested. Applicants for a New
Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable
third-party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then
the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue
the New Warrant.

 

8.
Reservation of Warrant Shares. The Company covenants that it will reserve and keep available out of the aggregate of its
authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon
exercise of this Warrant as herein provided, one hundred percent (100%) of the number of Warrant Shares which are initially issuable
and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights
of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that
all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance
with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company will take all such
action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common
Stock may be listed.

 

    	4

    	 	 	 

    

 

9.
Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject
to adjustment from time to time as set forth in this Section 9.

 

(a)
Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on
its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii)
subdivides its outstanding shares of Common Stock into a larger number of shares, or (iii) combines its outstanding shares of
Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and the denominator
of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant
to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or combination.

 

(b)
Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, distributes to all holders of Common
Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding
paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, “Distributed
Property”), then, upon any exercise of this Warrant that occurs after the record date fixed for determination of stockholders
entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable
upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of
such number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date.

 

(c)
Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation
of the Company with or into another Person, in which the Company is not the survivor and the stockholders of the Company immediately
prior to such merger or consolidation do not own, directly or indirectly, at least fifty percent (50%) of the voting securities
of the surviving entity, (ii) the Company effects any sale of all or substantially all of its assets or a majority of its Common
Stock is acquired by a third party, in each case, in one or a series of related transactions, (iii) any tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which all or substantially all of the holders of Common
Stock are permitted to tender or exchange their shares for other securities, cash or property, or (iv) the Company effects any
reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted
into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of
Common Stock covered by Section 9(a) above) (in any such case, a “Fundamental Transaction”), then the Holder
shall thereafter receive, upon exercise of this Warrant, in lieu of any Warrant Shares, the same amount and kind of securities,
cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been,
immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full
of this Warrant without regard to any limitations on exercise contained herein (the “Alternate Consideration”).
The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof,
any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate
corporation or entity shall assume the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with
the foregoing provisions, the Holder may be entitled to purchase and/or receive (as the case may be), and the other obligations
under this Warrant. The provisions of this paragraph (c) shall similarly apply to subsequent transactions analogous to a Fundamental
Transaction.

(d)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) and (e) of
this Section, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased
proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased number
of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

 

(e)
Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest share, as applicable.

(f)
Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will,
at the written request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant
and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number
or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions
giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the
Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

 

(g)
Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution
of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or
warrants to subscribe for or purchase any capital stock of the Company or any subsidiary, (ii) authorizes or approves, enters
into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary
dissolution, liquidation or winding up of the affairs of the Company, then, except if such notice and the contents thereof shall
be deemed to constitute material non-public information, the Company shall deliver to the Holder a notice describing the material
terms and conditions of such transaction at least ten (10) Trading Days prior to the applicable record or effective date on which
a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company
will take all steps reasonably necessary in order to ensure that the Holder is given the practical opportunity to exercise this
Warrant prior to such time so as to participate in or vote with respect to such transaction; provided, however, that the
failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described
in such notice.

for any such fractional shares.

 

12.

be as set forth in the Agreement unless changed by such party by two Trading Days’ prior notice to the other party in accordance
with this Section 12.

 

13.

Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged
or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation
