Siebert Expands Access to Tokenized Securities Through New Collaboration with tZERO and Streamex

Collaboration brings gold-backed, yield-bearing tokenized security, GLDY, to eligible investors through Siebert’s brokerage and institutional distribution channels

Siebert Financial Corp., a diversified financial services company, through its wholly owned subsidiary Muriel Siebert & Co. LLC, announced a new collaboration with tZERO Group, Inc. (“tZERO”) and Streamex Corp. (“Streamex”) to expand access to tokenized securities through regulated digital markets infrastructure.

Through the collaboration, Muriel Siebert & Co. will make Streamex’s GLDY, a gold-backed, yield-bearing tokenized security, available to eligible accredited and institutional investors through Siebert’s wealth management and institutional distribution channels through a private placement conducted under Reg. D Rule 506 (c). GLDY will be supported by tZERO’s regulated digital securities infrastructure, including onboarding, custody, secondary market infrastructure, compliance, and lifecycle services.

The collaboration represents a practical step in bringing blockchain-enabled financial products into the traditional brokerage experience. Eligible investors can work with a Siebert broker to evaluate GLDY without needing direct blockchain knowledge or separate crypto onboarding.

“At Siebert, our role is to help investors access what’s next in the markets through a trusted brokerage relationship,” said John J. Gebbia, Chief Executive Officer of Siebert. “GLDY is an example of how traditional finance and blockchain-enabled infrastructure can work together without adding complexity for the investor. Clients can speak with their Siebert broker, evaluate whether GLDY fits their goals and risk profile, and, where appropriate, purchase it through a brokerage account.”

For Siebert, the collaboration also supports the continued growth of its investment banking and capital markets platform, with a focus on financial services, FinTech, blockchain, digital assets, and other sectors where traditional market infrastructure is evolving.

“Tokenized securities are moving from concept to execution,” said Ajay Asija, Co-Head of Investment Banking at Siebert. “For issuers, this creates new ways to think about distribution, investor access, and market structure. For investors, it brings emerging asset classes into a more familiar, regulated framework. That is where Siebert can play a meaningful role.”

tZERO will provide the full technology and regulated infrastructure stack supporting Siebert’s digital securities initiative, including investor onboarding, custody, trading infrastructure, and compliance services.

“Traditional financial institutions increasingly recognize that tokenized securities require more than blockchain technology. They require regulated market infrastructure,” said Alan Konevsky, Chairman and Chief Executive Officer of tZERO. “We built tZERO to provide that foundation, giving firms like Siebert a single integrated platform for digital markets.”

Streamex developed GLDY as a tokenized security designed to bring gold-backed exposure and yield-bearing features into a regulated investment structure. Through the collaboration, GLDY can now reach investors through established brokerage and institutional channels.

“By partnering with Siebert and tZERO, GLDY can reach investors through channels they already know and trust,” said Henry McPhie, Co-Founder and Chief Executive Officer of Streamex. “That kind of access is what helps tokenized securities move into the mainstream.”
