## Source summary

PYMNTS reports that Diameter Pay raised a USD 10 million Series A co-led by CMT Digital and Lightspeed Faction. Diameter Pay's primary release confirms the round and says its API gives financial institutions access to U.S.-dollar virtual accounts, domestic and international payment rails, stablecoin on- and off-ramps and embedded compliance controls through multiple U.S. banking partners.

## Why it matters

The funding supports a connective layer between regulated U.S. dollar banking and stablecoin rails for institutions moving money across borders. Diameter Pay says it processed more than USD 10 billion year-to-date in 2026, but that is a company-supplied figure rather than an independently audited result. The sources disclose no valuation, client count, corridor mix, fees, FX spread, settlement-time distribution or failure rate.
