Dilendorf Law Firm assists clients with obtaining federal and state registration to operate as an Alternative Trading System (ATS) for issuing and trading tokenized securities on a blockchain.

While ATS is so far the best suited model for creating digital asset marketplaces for real estate, NFTs and operating businesses, registration and operation of ATS platforms that facilitate trading of tokenized securities involves novel issues and challenges.

Our experience in digital assets and traditional securities, joined by constant communication with the regulators, provides for a unique and effective ATS solution to our clients.

Helping Clients Navigate Through ATS Registration Requirements and Challenges

Digital asset platforms, which are considered trading securities in the US, are subject to securities laws requiring such platforms to be registered as a national securities exchange (NSE) or fall within an exemption from an NSE registration.

One exemption from registration as an NSE allows a company to conduct a digital asset platform business if such company is registered as an ATS.

A lot of platforms providing a marketplace for digital tokens fall squarely within the definition of an ATS.  Every ATS must still be registered with the SEC, provide multiple disclosures, implement security measures and comply with the federal reporting requirements, as well as state laws in each state where the ATS operates.

Specifically, Regulation ATS requires that every ATS must (i) register with the SEC as a broker-dealer, (ii) become a member of a self-regulatory organization (SRO), such as FINRA, (iii) file an extensive initial operating report (Form ATS) and (iv) have an ongoing compliance program to maintain the ATS and broker-dealer operations.

ATS registration process includes voluminous submissions to the SEC, including information about the traded securities, subscribers, operating procedures, etc. The ATS application is quite extensive and complex.

The scope of the application involves demonstrating to the SEC, among other things, a detailed technical description of the ATS operation procedures (e.g., custody, compliance, the process for booking orders, etc.), a description of the types of tokenized securities to be traded, description of users on the platform, capacity, integrity, and security of automated blockchain systems.

After registration, the ATS will have to comply with ongoing reporting requirements and other obligations, such as file quarterly transaction summaries and permit examination and inspection of the site, systems, and records by the SEC and FINRA in case of inspection or investigation. Also, as broker-dealers and FINRA members, ATSs platfroms are subject to strict standards of due diligence.

In addition, the SEC recently announced that it had voted to adopt amendments to Regulation ATS to require, among other things, stringent public disclosures of an ATS’ conflict of interests, risk of leakage of sensible information, procedures and operations, as well as additional safeguards dealing with confidential information.

Types of Tokenized Securities that Can Be Traded on ATS Platforms

  • Tokenized real estate;
  • Tokenized Venture Capital and hedge funds;
  • Interests and shares in startups and established businesses;
  • Fractionalized collectibles (classic cars, art, precious stones and metals);
  • Digital art and NFTs in the form of securities; and
  • Digitized intellectual property, royalties, music.

Guiding Clients Through Each Step of ATS Registration

One of the challenges for registering an ATS is that the SEC and FINRA currently lack sufficient experience and technical understanding of the digital assets and trading platforms, which requires back-to-back communication and meetings with FINRA throughout the registration process.

Our partners are in the constant process of communicating with the SEC and FINRA representatives regarding the most efficient ways of registering and operating an ATS.
