BioSig, Streamex Secure $1.1B to Launch Gold-Backed Token Empire on Solana

The joint announcement, made via a press release, outlined a two-pronged financing structure: $100 million in senior secured convertible debentures and a $1 billion equity line of credit. The funds will be deployed to build and scale a blockchain-powered ecosystem that tokenizes physical assets, starting with gold and integrates them into digital capital markets, with a particular emphasis on speed, liquidity, and trustless transparency.

BioSig, historically known for its medtech innovations in electrophysiology, has undergone a radical transformation following its May 2025 reverse merger with Streamex. That transaction effectively repositioned the company as a blockchain-first platform with ambitions to become a major player in RWA tokenization.

Under the terms of the merger, Streamex became a wholly owned subsidiary of BioSig, and leadership shifted accordingly. Streamex co-founder Henry McPhie now serves as CEO of the combined entity, while Morgan Lekstrom, also a Streamex co-founder, assumed the role of Chairman of the Board. Former BioSig CEO Anthony Amato retained a board seat but stepped away from day-to-day operations.

BioSig CEO and Streamex Co-Founder Henry McPhie emphasized the significance of the financing round, describing it as a transformative step forward for both companies and the broader financial ecosystem. “This financing marks a pivotal moment not only for Streamex and BioSig, but for the evolution of global financial markets. By combining the value of physical gold with the innovation of blockchain, we are building a company grounded in what we believe to be the world’s most trusted store of value while enabling a scalable, high-return business model through tokenization. Our mission is to unlock liquidity, transparency, and accessibility across the $142 trillion commodities market, and this milestone is just the beginning.”

The financing consists of a $100 million tranche in senior secured convertible debentures maturing 24 months from issuance. The debentures bear a 4% annual interest rate, which increases to 18% in the event of default. They are convertible into common stock at a fixed price, and are secured by a first-priority lien on certain BioSig assets.

The second component, a $1 billion equity line of credit, allows BioSig to sell registered common stock over a 36-month period, providing flexibility for long-term capital deployment. The securities were sold in private placements exempt from registration under the Securities Act, but a resale registration statement is expected to be filed.

The financing was facilitated by a consortium of financial institutions including Cantor Fitzgerald & Co., Clear Street LLC, and Needham & Company, with CIBC World Markets acting as strategic advisor.

At the core of the plan is the tokenization of gold and gold-linked structured products. But unlike existing models, such as Paxos’s PAXG or Tether Gold, Streamex intends to fund and hold physical gold directly on its balance sheet before issuing tokens backed 1:1 by the underlying assets.

According to the company, token issuance will be backed by audited reserves of physical gold, with an emphasis on regulatory transparency and investor protection. Tokens will initially be launched on Solana, chosen for its speed and low-cost scalability. A launch of the first tokenized gold asset is expected by early 2026.

Revenue streams will come from a variety of sources including origination fees, tokenization fees, spread income, and secondary trading activity.

The ultimate goal of the strategy is to bring a significant portion of the global commodities market, which is estimated to be worth $142 trillion, onto blockchain rails. In addition to gold, future products could involve oil, natural gas, agricultural futures, and rare earth metals.

By leveraging blockchain’s ability to fractionalize ownership and enhance settlement efficiency, the combined company hopes to democratize access to commodities, traditionally available only to institutional players.
