Muriel Siebert & Co. selected Tzero's platform to enter tokenized securities markets on June 29, 2026. The first product supported under the partnership is GLDY, a gold-backed tokenized security developed by Streamex Corp. and restricted to accredited investors. Siebert Financial reported $94.2 million in revenue for full-year 2025 and $19.5 billion in client assets as the publicly traded broker-dealer expands into blockchain-based capital markets through Tzero's regulated infrastructure stack.
Tzero Platform Provides Full Lifecycle Infrastructure
The firm, founded in 1967 by the first woman to own a seat on the New York Stock Exchange, will leverage Tzero's integrated platform to handle investor onboarding, compliance, issuance support, custody, secondary market infrastructure, and ongoing lifecycle services. The partnership was announced on Monday. Tzero's platform covers investor onboarding and KYC, issuance support and broker-dealer services, custody of tokenized securities, secondary market infrastructure, and clearing, settlement, and transfer agent services. Rather than build proprietary digital asset capabilities, Siebert opted for Tzero's regulated technology stack.
GLDY Structured as Rule 506(c) Private Placement
The initial product supported by the deal is GLDY, a gold-backed, yield-bearing tokenized security developed by Streamex Corp., a technology company focused on bringing commodity markets on-chain. The offering is structured as a private placement under Rule 506(c) of Regulation D of the Securities Act of 1933, limiting access to accredited investors. Siebert will act as placement agent, providing investors a broker-dealer experience while the underlying infrastructure runs on Tzero's blockchain-based platform.

Gebbia, CEO of Siebert, remarked: "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."
