ALT5 Sigma Corporation and Fundamental Interaction Usher in New Era of Institutional Crypto Trading Access for Finra Broker-Dealers

LAS VEGAS, NEVADA / ACCESS Newswire / July 30, 2025 / ALT5 Sigma Corporation (NASDAQ:ALTS)(FRA:5AR1) (“ALT5” or the “Company”), a fintech company delivering blockchain-powered payment and trading infrastructure for global merchants and financial institutions, today announced the successful integration of its institutional-grade ALT5 Prime FIX API with Fundamental Interaction, a leading provider of advanced trading technology for U.S. FINRA-registered broker-dealers and Alternative Trading Systems (ATSs).

This integration delivers seamless FIX-based access to digital asset markets directly into the infrastructure trusted by thousands of broker-dealers and trading platforms, representing a significant step toward unifying traditional capital markets with institutional-grade cryptocurrency execution.

“By integrating with Fundamental Interaction’s Real-Time Trading System, we are enabling FINRA-regulated firms to offer secure and compliant access to crypto markets alongside equities and alternatives,” said Peter Tassiopoulos, CEO of ALT5 Sigma Corp. “This is a turnkey pathway for regulated institutions to engage in digital asset trading with the tools, workflows, and auditability they already use.”

Integration Highlights:

• Real-time execution and settlement for BTC, ETH, SOL, and other digital assets

• FIX 4.4 protocol compatibility for routing, clearing, and trade surveillance

• 24/7 crypto market access through the same GUI used for multi-asset equities and ATSs

• KYC/AML and regulatory compliance tools embedded in the trade stack

• Risk management modules for institutional client mandates

Market Context: The FINRA Broker-Dealer Opportunity

There are over 3,300 FINRA-registered broker-dealers in the United States, collectively managing trillions of dollars in assets and facilitating billions of trades annually across equities, fixed income, and alternative assets. According to FINRA’s latest report¹, more than $110 trillion in transaction volume flows through U.S. broker-dealers each year – representing a powerful distribution and execution channel for emerging asset classes like digital assets.

The ALT5-Fundamental Interaction integration provides these institutions with a direct and compliant way to expand their product offerings to include regulated digital asset trading, while maintaining operational efficiency and audit-ready reporting.

“Our clients have asked for a way to integrate digital assets without reinventing their workflow,” said Shawn Sloves, CEO of Fundamental Interaction. “With ALT5 Sigma’s FIX API, they can now offer institutional-grade crypto execution in the same environment they already use for trading equities and alternatives – backed by compliance, risk controls, and market depth.”
