Muriel Siebert & Co., a Wall Street broker-dealer managing approximately $20 billion in assets, has selected tZERO Group's full-stack digital securities platform to support its expansion into tokenized securities, the companies announced June 29, 2026.
The partnership provides Siebert with tZERO's regulated technology and broker-dealer ecosystem, covering investor onboarding, compliance, issuance support, custody, secondary market infrastructure, and lifecycle management for digital securities. This turnkey approach allows established financial institutions to enter the digital asset market without building proprietary infrastructure from scratch.
“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, in a statement. “We built tZERO to provide that complete, independent foundation, enabling leading firms like Siebert to enter digital markets through a single, integrated platform.”
The first offering under the collaboration will be Streamex Ltd.'s GLDY token, a gold-backed, yield-bearing tokenized security developed by Streamex Corp. The private placement, conducted under Rule 506(c) of Regulation D, provides accredited investors with access to tokenized gold through a traditional broker acting as placement agent, while leveraging regulated blockchain-based market infrastructure.
“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,” said John J. Gebbia, CEO of Siebert. “Our relationship with tZERO gives us the infrastructure to enter this market with discipline, while building for where financial markets are headed.”
tZERO's platform offers a comprehensive suite of services including 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, tZERO provides an integrated infrastructure designed to support the complete lifecycle of tokenized securities.
The announcement underscores growing institutional adoption of tokenized securities infrastructure as established financial firms seek compliant pathways into digital capital markets.
