 Re: Initial
Public Offering 
 Ladies and Gentlemen: 
 This letter
(this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and between Hash Space Acquisition Corp, a Cayman
Islands exempted company (the “Company”), and Chardan Capital Markets, LLC (the “Representative”), as the representative of the several underwriters (the “Underwriters”),
relating to an underwritten initial public offering (the “Public Offering”) of 4,000,000 of the Company’s units (including up to 600,000 units that may be purchased to cover over-allotments, if any) (the
“Units”), each comprised of one ordinary share of the Company, par value $0.0001 per share (the “Ordinary Shares”) and one right (the “Right”). Each Right entitles the holder
thereof to receive one-tenth (1/10) of one Ordinary Share upon the consummation of the Company’s initial business combination, subject to adjustment. The Units shall be sold in the Public Offering
pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the
“Commission”) and the Company shall apply to have the Units listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 10 hereof. 

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Fucheng Technology Group Limited, a Hong Kong limited liability company (the “Sponsor”), and the other undersigned persons
(each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows: 

1. The Sponsor and each Insider agrees that if the Company seeks shareholder approval of a proposed Business Combination (as defined below),
then in connection with such proposed Business Combination, it, he or she shall (i) vote any Ordinary Shares owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any Ordinary Shares owned by it, him or
her in connection with such shareholder approval. 
 2. The Sponsor and each Insider hereby agrees that in the event that the Company fails
to consummate a Business Combination within 12 months from the closing of the Public Offering (or up to 18 months from the closing of the Public Offering if the Company extends the period of time to consummate a Business Combination, as described in
more detail in the Prospectus), or such later period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, the Sponsor and each Insider shall take all
reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, subject to lawfully available funds
therefor, redeem 100% of the Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account,
including interest (which interest shall be net of taxes payable and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public
Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of
the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of
applicable law. The Sponsor and each Insider agrees to not propose any amendment to the Company’s amended and restated memorandum and articles of association (a) that would affect the ability of Public Shareholders to exercise redemption
rights with respect to the Offering Shares or modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 12 months (or up to 18 months) from
the closing of the Public Offering, or (b) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides its Public
Shareholders with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall
be net of taxes payable), divided by the number of then outstanding Offering Shares. 












 The Sponsor and each Insider acknowledges that it, he or she has no right, title, interest
or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares (as defined below) held by it. The Sponsor and each Insider hereby
further waives, with respect to any Ordinary Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available
in the context of a shareholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares (although the Sponsor and the Insiders shall be entitled to redemption and liquidation
rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within 12 months (or up to 18 months) from the closing of the Public Offering, or such later period approved by the Company’s
shareholders in accordance with the Company’s amended and restated memorandum and articles of association). 
 3. In the event of the
liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other equity holders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim
whatsoever) to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent public accountants) for services rendered or products sold to the Company or (ii) a prospective
target business with which the Company has discussed entering into a transaction agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent
necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below
(i) $10.10 per share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each
case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the
Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to
be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably
satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense. 

4. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 600,000 Units within 45
days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate equal to 150,000 multiplied by a fraction, (i) the numerator of
which is 600,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 600,000. 

All references in this Letter Agreement to Founder Shares of the Company being forfeited shall take effect as surrenders for no consideration
of such Founder Shares as a matter of Cayman Islands law. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder Shares will represent 20.0% of the Company’s
issued and outstanding Ordinary Shares after the Public Offering (assuming the Initial Shareholders do not purchase any units in the Public Offering and excluding the Private Shares). The Initial Shareholders further agree that to the extent that
the size of the Public Offering is increased or decreased, the Company will effect a capitalization or share repurchase or redemption or other appropriate mechanism, as applicable, immediately prior to the consummation of the Public Offering in such
amount as to maintain the ownership of the Initial Shareholders prior to the Public Offering at 20.0% of the Company’s issued and outstanding Ordinary Shares upon the consummation of the Public Offering (assuming the Initial Shareholders do not
purchase any units in the Public Offering and excluding the Private Shares). In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 600,000 in the numerator and denominator of the formula in
the first sentence of this paragraph shall be changed to a number equal to 15% of the number of Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to 150,000 in the formula set forth in the immediately
preceding sentence shall be adjusted to such number of Founder Shares that the Founder Shares would represent an aggregate of 20.0% of the Company’s issued and outstanding Ordinary Shares after the Public Offering (assuming the Initial
Shareholders do not purchase any units in the Public Offering). 












 5. The Sponsor and each Insider hereby agrees and acknowledges that: (i) the
Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b) and 8 of this Letter Agreement (ii) monetary damages may not be
an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to seek injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event
of such breach. 
 6. (a) The Sponsor and each Insider agrees that it, he or she shall not Transfer (as defined below) any Founder Shares
until the earlier of (A) with respect to 50% of the Founder Shares, for a period ending on the earlier to occur of the six-month anniversary of the completion of the Business Combination or the date on
which the closing price of the Ordinary Shares exceeds $12.50 for any 20 trading days within a 30-day trading period following the closing of the Business Combination; (B) with respect to the remaining
50% of the Founder Shares, for a period ending on the six-month anniversary of the closing of the Business Combination or (C) in each case, subsequent to the Business Combination, the date on which we
complete a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the Public Shareholders having the right to exchange their Ordinary Shares for cash, securities or other property (the
“Founder Shares Lock-up Period”). 
 (b) The Sponsor and each Insider agrees
that it, he or she shall not Transfer any Private Units (including the Private Shares and Private Rights) until 30 days after the completion of a Business Combination (the “Private Placement Units
Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 (c) Notwithstanding the provisions set forth in paragraphs 6(a) and 6(b), Transfers of the Founder Shares and Private Units (including
the Private Shares and Private Rights), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any affiliate of the Sponsor, any members of the
Sponsor, or any of its affiliates, officers, directors, direct and indirect equityholders, (b) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the
individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an
individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of a business combination at prices no greater than the price at which the securities were originally
purchased; (f) in the event of the Company’s liquidation prior to the completion of the Company’s initial business combination; or (g) by virtue of the laws of Hong Kong or the Sponsor’s limited liability company agreement
upon dissolution of the Sponsor, provided, however, that in the case of clauses (a) through (e), or (g) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions. 

7. The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any
securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company, if any (including any such information
included in the Prospectus), is true and accurate in all respects and does not omit any material information with respect to such Insider’s background. The Sponsor and each Insider’s questionnaire furnished to the Company, if any, is true
and accurate in all respects. The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for, any injunction,

has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it, he or

 8. Except as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any
affiliate of the Sponsor or any Insider, nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or
in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is). 

9. The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation,
