James Wigginton Of Counsel

Sacramento; Silicon Valley

Blockchain and cryptocurrency technologies have caused business leaders to rethink the way we own, govern and share the benefits of enterprise. James advises entrepreneurs and investors as they pioneer new, more inclusive operating models in professional sports, finance, social media, gaming, agriculture and other industries.

To do this, James draws from two complementary sources of experience. The first is his practice assisting public companies, private equity funds and venture capitalists with registered and unregistered securities offerings; high-stakes M&A; corporate governance; and Exchange Act reporting. The second is his experience advising clients outside the Wall Street and Silicon Valley mainstream, including cooperatives, limited cooperative associations and nonprofit corporations. By combining these two worlds, James is able to offer unexpected legal solutions to blockchain-based companies as they seek venture financing, design and issue tokens, and select business entities for DAOs.

James also appreciates the inherently global reach of blockchain and cryptocurrency. After law school, he spent two years clerking for the US Court of International Trade in New York City. Before that, James lived for two years in the eastern Ukrainian cities of Dnipro, Donetsk, Kharkiv and Mariupol. James is fluent in Russian and maintains ties with his friends in the war zone.
