ITEM 3.02 Unregistered Sales of Equity Securities

     On April 10, 2018, American BlockchainBiochar Corporation

              Ajay Keshap         2,500,000

    With the issuance of the stock and the redemption of 19,500,000
shares of stock (discussed below), the Company effected a change in
its control and the new majority shareholder(s) elected new management
of the Company.  The Company intends to develop its business plan by
acquiring Karr Group of Companies,, a California LLC. The Company
changed its name as part of the change in control.  If the Company
makes any acquisitions, mergers or other business combination, the

a shell company.

    On April 9, 2018, the following events occurred which resulted
in a change of control of the Registrant:

    1.  The Registrant cancelled an aggregate of 19,500,000 of the
then 20,000,000 shares of outstanding stock valued at par.

    2.   The then current officers and directors resigned.

    3.   New officer(s) and director(s) were appointed and elected.

Form 10-12G filed on July 7, 2017 as amended and supplemented by

California LLC, Karr Group of Companies.  The Karr Group of Companies
is a parent company which owns and operates a biochar production plant
company in the State of Washington.  The company manufactures specialty
biochar under the brand name "CannGrow" for the cannabis industry and
"Karrchar" for other agricultural operations.  The company utilizes a
fractional hydro cracking technology to turn waste biomass into usable
products including CannGrow and Karrchar, bio charcoal ("Surefire')
and fuel gas ("Karrgas"). The company believes that it may be the
first technology that produces commercial quantities of biochar/bio
charcoal on a continuous basis without the bio oil-byproduct, a
hazardous waste creating disposal and cost issues.  The company sells
its products wholesale to soil formulators and resellers.
