At zerohash, we’ve always believed that stablecoins and blockchain-based payments aren’t a side story—they’re quickly becoming the backbone of how money moves around the world. And as adoption accelerates, so does the need for deep operational, regulatory, and financial infrastructure expertise.
That’s why we’re excited to welcome Aaron Karczmer and Danny Rosenthal to the zerohash Boards. Both bring decades of leadership from the front lines of payments, trading, compliance, and high-scale financial systems. Their guidance comes at a pivotal moment for the industry—and for zerohash.
Aaron Karczmer led major global functions at PayPal and spent years shaping risk, compliance, and operations at American Express. He now serves as CEO of K2 Integrity, one of the most respected firms in risk and cyber advisory. He joins the zerohash llc Board, which oversees our U.S.-regulated custody and money-movement entity, which is a core part of how we build trust and scale responsibly.
Danny Rosenthal is a builder through and through. As former CEO of Apex Crypto and CTO at PEAK6, he designed the high-volume trading, clearing, and payments systems that power modern marketplaces. He joins the zerohash liquidity services Board, focused on the global liquidity engine that underpins our stablecoin and settlement products.
This dual-board model reflects how Zerohash operates: regulated rigor at the core, paired with global scale and relentless product innovation.
Our CEO, Edward Woodford, put it plainly: “Global finance is already converging with digital assets, and operational scale and regulatory trust have never been more critical. Aaron and Danny have both built and operated some of the most complex financial systems in the world.”
Aaron echoed the importance of this moment for the industry: “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 Danny sees a transformation underway: “The convergence of high-speed settlement, tokenization, and regulatory clarity is creating real change. zerohash is at the center of that movement.”
As financial institutions race to modernize their payment rails and prepare for an onchain future, we’re increasingly the infrastructure behind that shift. Bringing in leaders of Aaron and Danny’s caliber isn’t just additive—it accelerates our ability to scale with the trust, resilience, and speed the industry now expects.
Every industry is moving toward instant, global, programmable money. Stablecoins are becoming the connective tissue. And enterprises—from payroll platforms to brokerages to global fintechs—are building on blockchain rails because they offer what traditional systems can’t: real-time settlement, fewer intermediaries, and global reach.
zerohash is building the infrastructure that makes all of this actually work inside large organizations, with compliance at the center.
Adding Aaron and Danny to our boards strengthens that foundation even further.
