ALT5 Sigma is a Las Vegas-based fintech company that provides enterprise-grade blockchain-powered infrastructure for digital asset management. The company enables banks, fintechs, and institutions to trade, transact, and settle digital assets through a comprehensive suite of modular solutions. Its primary offerings include an exchange and trading platform, stablecoin and global payment services, payment processing, market making and liquidity provision, institutional-grade custody, and asset tokenization capabilities. ALT5 Sigma operates through two main platforms: ALT5 Pay, a cryptocurrency payment gateway allowing merchants to accept digital asset payments, and ALT5 Prime, an electronic over-the-counter trading platform for buying and selling digital assets. The company is registered with regulatory bodies including FinCEN in the United States, FINTRAC in Canada, and as a Virtual Asset Service Provider with Lithuania's central bank. By combining institutional-grade security with regulatory compliance, ALT5 Sigma addresses the infrastructure gap preventing widespread digital asset adoption across traditional finance.
