Explanation of Responses:

1. On October 7, 2026, SolSync Solutions Partnership, an Alaska general partnership (the "Partnership"), dissolved and distributed all of the securities of the Issuer that it held to its two partners in kind, in complete liquidation of their partnership interests and in proportion to their respective percentage interests, for no consideration. Mr. Onorati previously reported only the securities held by the Partnership in which he had a pecuniary interest.

2. Parker White and DeFi International Holding, LLC were partners of SolSync Solutions Partnership, an Alaska general partnership. Parker White was the managing partner and maintained voting and dispositive control over the securities held by the Partnership. Following the distribution, the Partnership holds no securities of the Issuer and is being wound up.

3. DeFi International Holding, LLC, a Wyoming limited liability company, was a partner of the Partnership and received these securities in the distribution. Mr. Onorati is a manager of DeFi International Holding, LLC and may be deemed to beneficially own the securities it holds.

4. Mr. Onorati is the control person as director and president of 3277447 Nova Scotia Ltd and may be deemed to control 3277447 Nova Scotia Ltd.
