Sharplink, Inc. is a global digital asset treasury firm, primarily functioning as an institutional-grade platform for managing Ethereum. Its operations are divided into two primary divisions: Ether (ETH) Treasury Management and Affiliate Marketing. The ETH Treasury Management division is dedicated to the strategic acquisition and dynamic oversight of Ethereum, positioning it as a long-term holding for the company's treasury. This involves both native and liquid staking strategies, all conducted within a robust framework that prioritizes governance, secure custody, and comprehensive risk mitigation. Conversely, the Affiliate Marketing segment specializes in offering performance-driven client acquisition solutions to businesses in the sportsbook and online casino gaming industries. This is achieved by generating substantial user traffic and acquiring new players for licensed gaming entities, primarily leveraging its international affiliate network, PAS.net, alongside a collection of digital assets tailored for specific U.S. states. The company, previously operating as SharpLink Gaming, Inc., rebranded to Sharplink, Inc. in February 2026. Established in 2019, Sharplink's corporate headquarters are located in Miami, Florida.
