In July 2025, Joseph Chalom joined SharpLink as Co-Chief Executive Officer, bringing with him over 20 years of institutional leadership at the intersection of traditional finance and digital assets. As former Managing Director and Head of Strategic Ecosystem Partnerships at BlackRock, Joseph was instrumental in driving the firm’s global strategy across digital assets, fintech innovation, and blockchain infrastructure. Under his leadership, BlackRock launched some of the most successful digital asset products in history, including the iShares Bitcoin Trust (IBIT), which became the largest Bitcoin ETF globally, and the iShares Ethereum Trust (ETHA), the leading spot Ethereum ETF in the U.S. He also played a key role in advancing tokenization through the launch of BUIDL — the first tokenized U.S. Treasury fund built on Ethereum — and oversaw strategic partnerships with Coinbase, Securitize, and other major players shaping the digital asset ecosystem. Joseph’s work bridged the worlds of Wall Street and digital assets, bringing compliant, institutional-grade access to crypto and helping scale blockchain-based financial infrastructure. Prior to leading BlackRock’s digital asset efforts, Joseph served as the firm’s Deputy Chief Operating Officer and Chief Operating Officer of BlackRock Solutions, where he managed the global expansion of Aladdin, the firm’s industry-leading portfolio and risk management platform. A graduate of Johns Hopkins University (BA, International Affairs) and Columbia Law School (JD), Joseph began his career as a corporate and regulatory attorney before transitioning into financial technology leadership. He also served on the boards of Securitize and Clarity AI, furthering his commitment to next-generation capital markets and sustainability-focused innovation. At SharpLink, Joseph is focused on building the most trusted Ethereum treasury and advancing the company’s mission to bring ETH to the center of global finance.
