NEW YORK, Nov. 13, 2025 (GLOBE NEWSWIRE) -- zerohash, the leading crypto and stablecoin-as-a-service platform, today announced the appointment of Aaron Karczmer and Danny Rosenthal to its Boards of Directors. Together, they bring decades of leadership across payments, regulation, and financial infrastructure to guide zerohash through its next phase of growth.
Karczmer, former Chief Enterprise Services Officer at PayPal and longtime American Express executive, joins the zerohash llc Board, which oversees the company’s US-regulated custody and money-movement entity. Rosenthal, former CEO of Apex Crypto and CTO at PEAK6, joins the zerohash liquidity services Board, which focuses on the firm’s global liquidity stack. This different board structure reflects zerohash’s commitment to maintaining strong regulatory oversight while scaling its operational and product capabilities globally.
“Global finance is already converging with digital assets, and operational scale and regulatory trust have never been more critical,” said Edward Woodford, Founder and CEO of zerohash. “Aaron and Danny have both built and operated some of the most complex financial systems in the world. Their expertise will be invaluable as zerohash continues to lead the evolution of how money moves instantly, globally, and compliantly.”
Aaron Karczmer said: “I’m thrilled to join the zerohash Board at a time when the intersection of regulation, innovation, and trust matters more than ever. zerohash is setting the standard for how regulated infrastructure can power the next era of payments and finance, and I look forward to helping zerohash drive that forward.”
Danny Rosenthal said: “This is a pivotal moment for institutional payments and digital assets. The convergence of high-speed settlement, tokenization, and regulatory clarity is creating real transformation. zerohash is at the center of that movement, and I’m excited to support the team in unlocking the next generation of liquidity and payments flows.”
These appointments underscore zerohash’s momentum in payments and stablecoin innovation, following a year of significant partnerships and regulatory milestones. The company recently secured MiCAR authorization in Europe, partnered with Worldpay, Canton Network, and Public.com to power embedded digital asset experiences, and closed a $104 million Series D-2 fundraise to accelerate global growth.
