  • Business

    • Describe your business and go to market strategy.

Detox Digital Coins ( ‚ÄúDDCs‚ÄĚ) are real-estate backed security tokens representing an interest in the Detox Medical Digital Series, LLC. (‚Äėthe Series‚ÄĚ), established by SolidBlock to offer investors the opportunity to participate in the Detox Digital Coin which manages detoxification facilities, each with its unique and licensed approach to drug and alcohol and mental health recovery. The main underlying challenge and need for the project is the opioid epidemic which is a global malady, further exacerbated by the COVID-19 pandemic with an estimated 107,622 drug overdose deaths in the United States during 2021, an increase of nearly 15% from the 93,655 deaths estimated in 2020.

Our market strategy is two-pronged and consists of education about this niche real estate sector and the environmental and emotional impact investing in these facilities can have on the community of at-risk individuals.

  • What makes your approach unique within your industry?

For this offering SolidBlock, an internationally recognized pioneer in tokenization and the developer of a fully compliant tokenization platform, has teamed up with the Holdun Family Office (Bahamas) Ltd., and Omicrom Development, LLC (Delaware Incorporated), to raise up to USD $15M to purchase via tokenization additional facilities focusing on various levels of detox and healthy living care.

The Portfolio consists of real estate within the United States that is utilized to increase the number of substance abuse treatment programs available for those seeking a solution to opioid dependency. The Portfolio represents an investment in a niche commercial real estate sector that has insulation from the effects of the Coronavirus, and is considered ‚Äúessential business‚ÄĚ in the eyes of US federal and state governments. The Portfolio addresses a rapidly expanding market with an unmet demand: the exploding opioid crisis and the lack of treatment facilities.

Medi Solutions currently manages five thriving centers and anticipates acquiring additional centers that are specifically zoned and refurbished to provide diverse levels and stages of substance abuse programs.

Specifically, Detox Digital Coin will acquire facilities that address different levels of care for every state of recovery from substance abuse. These include:

  • Residential Drug and Alcohol Detoxification Centers
  • In-patient Drug and Alcohol Rehabilitation Centers
  • Sober Living Post Rehabilitation Residential Housing

The Series may hold, depending on the amount raised, up to 100% of several detox centers as delineated above. Each DDC is initially offered at a value of USD $1.

Using SolidBlock‚Äôs advanced platform on the Ethereum blockchain (the ‚ÄúSolidBlock Platform‚ÄĚ), investors will be able to purchase DDCs. The Company intends to use the proceeds of the sale of the DDCs (after payment of fees and offering expenses) to purchase an interest in the real property holding company, which wholly owns the medical detoxification centers.

  • Why are you a good partner for Centrifuge?

Collateralizing tokens that are backed by real world assets (RWAs) aligns with Centrifuge’s goal of unlocking liquidity for RWAs. This is the goal of Detox Digital Coin.

  • How do you differentiate yourself from competitors?

SolidBlock is introducing a new aspect to this niche commercial real estate sector, namely, tokenization. Real estate asset tokenization is an emerging trend representing the convergence of real estate investing and blockchain technology. Tokenization helps asset or fund owners raise capital more efficiently, and gives investors unprecedented access to private real estate investments, transparency, and liquidity.

DDC is a new series of Ethereum blockchain-based smart contract digital tokens consisting of software code meeting the ERC-20/1404 protocol standard as modified to meet transfer restriction requirements under applicable US securities law. The software code of the DDC Smart Contract will be based on open source code but will be proprietary and will not be published at this time.

SolidBlock’s state-of-the-art digital securities platform enables fractional ownership of the underlying assets or fractional entitlement to certain rights (revenue or interest) as well as trade of assets via OTC on the SolidBlock platform or through partner exchanges.

The Series seeks to execute and operate financial positions that will provide prospective purchasers of the DDC with the following benefits:

(i) the preservation and return of their capital contributions;

(ii) stable cash flow of quarterly distributions of a preferred interest equal to 8% of capital raised;

(iii) potential capital appreciation and sale of the Property after a 5-year term, with a 3-year extension to be determined in the sole discretion of the Company;

(iv) the realization of growth in the value of the Investments; and

(v) potential liquidity through a possible future listing of the DDC on a crypto market exchange, a marketplace to trade private digital securities.

  • How is your entity financed today, what are the current sources of capital:

Detox Digital Coin’s business model is based on fundraising and reaching the soft cap in order to execute and purchase the first property in the portfolio. There are currently five properties in the portfolio, each with a 10-year NNN lease with a built-in annual 3% raise.

  • Equity raised:

The Series seeks to raise up to $15,000,000 USD to invest into the Series which may hold, depending on the amount raised, up to 100% of several real property holding companies each of whom is the sole owner of a medical detoxification center (the ‚ÄúProperty‚ÄĚ or ‚ÄúProperties‚ÄĚ). We expect several tranches whereby there is a minimum cap of $3M.

  • Debt raised: N/A

  • What is your entity‚Äôs revenue/fee model:

Purchases of the DDCs will be paid in U.S. dollars. The Series may accept Bitcoin (‚ÄúBTC‚ÄĚ), Ethereum (‚ÄúETH‚ÄĚ), DASH, or other cryptocurrencies as payment for DDCs. Payment can also be made by wire transfer and credit card.

The funding objective is to raise $15,000,000 USD as outlined above in numerous tranches - each with a min. Cap of $3M and a maximum of $15M in accordance with the PPM. The offering price of each DDC is $1.00 and the minimum investment is $5,000 USD although the Series, in its sole discretion, may determine to lower the minimum amount. DDCs can be accessed and transferred (when and to the extent permitted under applicable regulations) through the SolidBlock Platform or held directly in a digital wallet.

  • DeFi

    • Outline why DeFi is important to your business strategy:

Blockchain and digital securities are changing the way we manage our investments and how they level the playing field for investors. The process of turning real world assets into security tokens‚ÄĒtokenization‚ÄĒmakes investments decentralized, immutable, and transparent, and allows investors to liquidate their holdings anytime. Tokenization also supports interoperability in the DeFi (decentralized finance) space, pushing forward the next revolution in banking. Here‚Äôs what DeFi can offer:

  • Permissionless and open access to financial transactions;
  • An independently operated decentralized mechanism with shared interoperable data points;
  • A non-custodial product that is programmable with smart contracts; and
  • An immutable system that is cryptographically verifiable.

We believe that the tokenization of real world assets will continue to be a growth industry, and we are using our platform to prepare our clients to be part of the blockchain economy. SolidBlock‚Äôs platform empowers asset owners to transact differently‚ÄĒbuy, sell, raise capital, and collateralize‚ÄĒand to manage their tokenized property in a decentralized fashion.

  • Articulate why Centrifuge‚Äôs community and protocol is a fit for financing:

SolidBlock‚Äôs TokenSuite‚ĄĘ platform tokenizes real world assets (RWAs) to prepare them for the blockchain economy. As a startup, we‚Äôre constantly seeking investors to invest in our vision, and we see Centrifuge as a natural collaborator in this effort.

Tokenized real estate is backed by real-world assets that have traditional valuations. They are a digital representation of ownership of an underlying asset. While the tokens themselves are virtual, the property they represent is tangible and is driven by the asset’s NAV (Net Asset Value).

Issuers of any kind of security are responsible for maintaining compliance, which can be a costly and burdensome process. Digital securities that have been properly programmed to include all relevant regulations are actually less prone to human error and are a far more efficient way to handle compliance.

In addition, if a digital security is lost or stolen, it can be burned (deleted), replaced by the issuer, and returned to the rightful owner.

In 2018, SolidBlock successfully tokenized the first commercial real estate project in US history, the St. Regis Hotel in Aspen, CO. We pioneered the legal, regulatory and technological framework that has become the industry standard for tokenized assets today.

Given Centrifuge’s commitment to support small businesses that are tokenizing RWAs, we believe SolidBlock is an excellent fit for the Centrifuge model.


  • Please explain the key risks inherent in this opportunity and asset class:

The DDC offered hereby are highly speculative in nature, involve a high degree of risk and should be purchased only by persons who can afford to lose their entire investment. There can be no assurance that the Company’s investment objectives will be achieved or that a secondary market would ever develop for the DDC, whether via the SolidBlock Platform, via third party registered broker-dealers or otherwise.

that prospective Investors should consider before investing in the DDC. An investment in the DDC may be exposed to other risks of an exceptional nature from time to time.
