dtcpay Closes $25 Million Series A With SBI Backing

Founded in 2023 and bootstrapped until this financing, Diameter Pay provides banks, fintech firms and digital-asset platforms with access to U.S. dollar virtual accounts, payment rails, stablecoin on- and off-ramps, and embedded compliance tools. The company sits at the junction of traditional banking and blockchain-based settlement, a growing area as financial institutions seek faster and more accessible cross-border dollar services without assembling banking, foreign-exchange and digital-asset infrastructure separately.

Diameter Pay said on Sept. 3, 2026, that it raised $10 million in its first outside funding round, a Series A co-led by CMT Digital and Lightspeed Faction. The equity financing began in April and closed in a single tranche in July. The company said it had processed more than $10 billion in payments year-to-date and had over 10,000 end users. Proceeds will expand banking and payment capabilities, deepen stablecoin and foreign-exchange infrastructure, and support technology and compliance tools for cross-border dollar movement.
