Siebert Financial Corp. (NASDAQ:SIEB) ("Siebert"), a diversified financial services company, through its wholly owned subsidiary Muriel Siebert & Co. LLC, today announced a new collaboration with tZERO Group, Inc. ("tZERO") and Streamex Corp. (NASDAQ:STEX) ("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.
