The Trade Is The Settlement

tZERO's vision is to strengthen capital markets through the use of technology, with a primary focus on blockchain technology.

The Capital Markets connect entrepreneurial businesses seeking to raise capital with investors seeking investments that will provide a return on their investment. Modern capital markets form a system that is integral to society. As a result, strengthening capital markets contributes to a variety of societal goods, including wealth formation, job creation, and the freedom to pursue entrepreneurial dreams

tZERO intends to strengthen capital markets by:


  • Increasing transparency
  • Providing a liquidity framework to markets 
  • Reducing reliance on costly intermediaries

The tZERO platform integrates cryptographically secure distributed ledgers with existing market processes to reduce settlement time and costs, increase transparency, efficiency and auditability.

tZERO seeks to bring enterprise-grade technology to burgeoning crypto capital markets and aims to integrate blockchain technology into traditional capital market functions. As the fintech and blockchain industries intertwine, the businesses that emerge will be:

  • Highly adaptable
  • Forward-thinking
  • Experienced 

tZERO meets all of these criteria and more. Our battle-tested technology stack sets us apart from other parties in our space, many of whom have only an outline of goals as their sole piece of intellectual property. Our huge investments in developing a regulatory strategy have laid the foundation for our vision to become reality.

tZERO plans to change the world.

tZERO's Trading Platform and Planned Token-Trading System

After several years of development, tZERO has positioned itself to capture the fast-growing digital securities market. To date, tZERO has the only platform that has ever traded a digital security, and we are working diligently to build a token trading system to trade securities.

The tZERO Token

The tZERO token (TZRO) is an ERC-20 compliant token or equivalent that will be offered as a security to qualified investors in accordance with US and other laws.


The tZERO token will pay 10% of adjusted gross revenue to token holders on a quarterly basis, subject to board approval and the conditions outlined in the offering memorandum. 

Promotes price stability by encouraging token holders to temporarily lock up tokens in order to receive dividends.

tZERO Platform Highlights



tZERO owns two SEC registered and FINRA Member broker-dealers, SpeedRoute LLC, a premier routing and execution firm, and PRO Securities LLC, as an Alternative Trading System (ATS), which is the first SEC and FINRA regulated ATS to enable and support secondary trading of a crypto security (Overstock's Blockchain Voting Series A Preferred).


tZERO’s Digital Locate Receipt software, which is in customer production testing, is designed to provide market participants with a more transparent, efficient, and compliant solution for the lending and borrowing of securities.


tZERO’s proprietary routing technology services over 125 broker dealers and offers connectivity, market access, smart order routing, and algorithmic trading solutions.


tZERO’s technology infrastructure currently processes 15-18 million traditional orders per day, and is equipped to handle over 100 million orders per day.


Our ATS allows for 24-hour trading (traditional equity securities), providing liquidity while others are closed.


tZERO has acquired a majority stake in a robo-advisory firm, capable of running advanced financial models and creating adaptive dynamic portfolios, the benefits of which may be available to token holders in the future.

tZERO Platform Highlights



To develop a token trading system capable of trading crypto-securities.


To allow firms worldwide to break the constraints of traditional finance in order to access a global pool of capital for crypto securities with the first trading system for secondary market liquidity.


The tZERO trading system would solve a huge problem for the crypto community by closing the liquidity gap for securities offerings. In the future, truly liquid security tokens may legally be allowed to trade through the tZERO system, creating a new, legal access point for secondary trading in these securities.


An operational tZERO trading system could fundamentally disrupt existing capital markets by potentially allowing any public or private company to trade their own tokenized security.


Continued innovation to instill investor confidence in tokenized security trading.
