Muriel Siebert & Co., LLC, a Wall Street broker-dealer overseeing approximately $20 billion in assets, has selected tZERO Group, Inc.'s end-to-end digital securities infrastructure to support its expansion into tokenized securities. The collaboration, announced June 29, 2026, enables Siebert to offer blockchain-based securities through tZERO's regulated technology and broker-dealer ecosystem, covering investor onboarding, compliance, issuance support, custody, secondary market infrastructure, and lifecycle management.
The implementation demonstrates how established financial institutions can leverage tZERO's integrated infrastructure rather than building proprietary digital asset capabilities from scratch. Alan Konevsky, Chairman and CEO of tZERO, stated, "Traditional financial institutions increasingly recognize that tokenized securities require more than blockchain technology – they require turnkey regulated market infrastructure." John J. Gebbia, CEO of Siebert, added, "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."
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. The private placement, utilizing Rule 506(c) of Regulation D, provides accredited investors with access to a tokenized gold investment through the familiar experience of working with a traditional broker. tZERO's services include investor onboarding, identity verification and KYC, issuance support, broker-dealer services, custody of tokenized securities, secondary market infrastructure, clearing and settlement, and transfer agent services.
Unlike point solutions that address only one aspect of digital asset markets, tZERO provides a comprehensive infrastructure platform designed to support the complete lifecycle of tokenized securities. The announcement further underscores growing institutional adoption of tokenized securities infrastructure as established financial firms seek compliant pathways into digital capital markets.
