Muriel Siebert & Co., LLC, one of Wall Street's most recognized broker-dealers with approximately $20 billion in wealth management and institutional distribution reach, has selected tZERO Group's end-to-end digital securities infrastructure to support its expansion into tokenized securities, the companies announced Monday.
The collaboration represents Siebert's entry into the rapidly growing market for blockchain-based securities through tZERO's regulated technology and broker-dealer ecosystem. Through the relationship, tZERO will provide the full technology and regulated infrastructure stack supporting Siebert's digital securities initiative—from investor onboarding and compliance through issuance support, custody, secondary market infrastructure, and ongoing lifecycle services.
“Traditional financial institutions increasingly recognize that tokenized securities require more than blockchain technology—they require turnkey regulated market infrastructure,” said Alan Konevsky, Chairman and Chief Executive Officer of tZERO. “We built tZERO to provide that complete, independent foundation, enabling leading firms like Siebert to enter digital markets through a single, integrated platform.”
The implementation demonstrates how established financial institutions can leverage tZERO's integrated infrastructure rather than building proprietary digital asset capabilities from scratch. Unlike point solutions that address only one aspect of digital asset markets or operate in closed-loop environments, tZERO provides a comprehensive infrastructure platform designed to support the complete lifecycle of tokenized securities.
The first offering supported by this collaboration will be Streamex Ltd.'s offering of GLDY, a gold-backed, yield-bearing tokenized security developed by Streamex Corp., a technology company focused on bringing commodity markets on-chain through tokenization. The private placement, utilizing Rule 506(c) of Regulation D under the Securities Act of 1933, provides accredited investors with access to a tokenized gold investment through the familiar experience of working with a traditional broker, acting as a placement agent, while benefiting from regulated blockchain-based market infrastructure.
“Siebert has always moved forward by helping more people access opportunity in the markets,” said John J. Gebbia, CEO of Siebert. “Tokenized securities represent an important evolution in how investors and issuers can connect, but the opportunity only works when innovation is matched with regulation, transparency, and trust. Our relationship with tZERO gives us the infrastructure to enter this market with discipline, while building for where financial markets are headed.”
Services provided by tZERO include investor onboarding and compliance, identity verification and KYC, issuance support, broker-dealer services, custody of tokenized securities, secondary market infrastructure, clearing and settlement capabilities, and transfer agent services. By utilizing tZERO's infrastructure, Siebert can offer digital securities capabilities while relying on an established, regulated technology stack built specifically for blockchain-enabled capital markets.
The announcement further underscores growing institutional adoption of tokenized securities infrastructure as established financial firms seek compliant pathways into digital capital markets. tZERO Group, Inc. (tZERO) and its broker-dealer subsidiaries provide an innovative liquidity platform for private companies and assets, offering institutional-grade solutions for issuers looking to digitize their capital table through blockchain technology.
