ALT5 Sigma Launches Lightning Network Integration to Power Instant Bitcoin and Tether Payments in Partnership with Voltage

Support for Bitcoin and Stablecoins on Lightning Underscores ALT5's Commitment to Scalable, Real-Time Settlement Infrastructure

LAS VEGAS, NEVADA / ACCESS Newswire / May 27, 2025 / ALT5 Sigma Corporation (the "Company" or "ALT5") (NASDAQ:ALTS)(FRA:5AR1), a fintech company that delivers blockchain-powered payment and trading infrastructure for global merchants and financial institutions, today announced that Lightning Network capabilities are now live on its platform.

This upgrade enables instant, low-cost Bitcoin payments on ALT5 and lays the foundation for Tether (USDT) stablecoin support over Lightning, delivering a powerful combination of speed, stability, and cost-efficiency for enterprises that depend on high-frequency digital transactions.

ALT5's Lightning integration is made possible through Voltage, a leading provider of enterprise-grade Lightning infrastructure. By embedding Lightning into its Crypto-as-a-Service ecosystem, ALT5 enables clients to benefit from real-time settlement, whether transacting in Bitcoin or increasingly in stablecoins such as USDT.

"Real-time payments are no longer optional-they're becoming essential for modern finance," said Peter Tassiopoulos, CEO of ALT5 Sigma. "With Lightning now available on our platform, we're giving institutions a direct path to instant Bitcoin payments and preparing for the growing demand for stablecoin settlement over Lightning."

The introduction of Lightning on ALT5 unlocks a new class of use cases for digital asset settlement, particularly in cross-border commerce, high-frequency trading, and global merchant payments. Clients can now dramatically reduce fees and confirmation times, while maintaining the robust compliance and operational controls built into ALT5's infrastructure.

"The ability to move Tether over Lightning is an inflection point for the industry," said Graham Krizek, CEO of Voltage. "It's a stable, scalable payment method layered on top of Bitcoin's security and ALT5 is making that future accessible to institutions today."

The evolving potential for stablecoin settlement over Lightning presents new opportunities for financial platforms. ALT5 is closely monitoring this space as part of its ongoing commitment to delivering scalable, future-ready payment infrastructure for global enterprises.

With Lightning now integrated, ALT5's platform supports a full range of crypto transaction protocols, enabling real-time settlement across Bitcoin, stablecoins, and multiple networks. Regardless of the asset or underlying technology, transactions can now be initiated, routed, and settled through ALT5's unified infrastructure.
