Siebert Expands Into Tokenized Securities Through tZERO's End-to-End Digital Markets Infrastructure

Muriel Siebert & Co., a broker-dealer managing approximately $20 billion in assets, has partnered with tZERO to integrate blockchain-based infrastructure for tokenized securities. This collaboration allows Siebert to offer end-to-end digital asset services, including investor onboarding, compliance, custody, and secondary market trading. By leveraging tZERO’s regulated technology stack, Siebert avoids the need to build proprietary digital asset capabilities from the ground up. The partnership’s first initiative involves supporting the private placement of GLDY, a gold-backed, yield-bearing tokenized security issued by Streamex Ltd. under Rule 506(c) of Regulation D. This move highlights a broader trend of established financial institutions adopting turnkey, compliant blockchain infrastructure to enter the digital capital markets. The integration signifies a shift toward institutional-grade, regulated platforms that bridge traditional brokerage experiences with the efficiency of tokenization. Ultimately, this partnership validates the demand for integrated, compliant solutions that enable traditional firms to modernize their offerings while maintaining regulatory standards.
