Las Vegas, NV / 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. FINRAregistered
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.”
