Within: Fintech

Fielding a multidisciplinary team with broad experience, Paul Hastings LLP’s practice boasts a wide range of capabilities handling matters across the fintech sector. The group's impressive client roster ranges from global corporates, such as Samsung — which it advised on a range of privacy, security, data ownership, advertising and marketing issues relating to the launch of Samsung Pay — to start-up companies including Even. The firm advised the latter on the launch of its financial health app in collaboration with Wal-Mart. The team has experience assisting clients navigating the cryptocurrency market and regulatory environment; Altanta-based practice head Chris Daniel and cybersecurity and data expert Behnam Dayanim in Washington DC are leading advice to Coinbase on the passing of a North Carolina state house bill allowing cryptocurrency exchanges to operate, as it is exempt from traditional money transmission laws. The group also leverages its M&A capabilities in transactions, such as assisting Moneygram on the recent proposed acquisition by Ant Financial; advising Paysafe Group on US regulatory aspects of its $3.9bn acquisition by Blackstone and CVC Capital Partners; and acting for Circle Internet Financial in connection with elements of its $400m acquisition of Poloniex. Other key names to note include San Francisco-based Thomas Brown, particularly for antitrust and competition in the financial services industry; Washington DC-based of counsel Lawrence Kaplan, who attracts praise for his ‘outstanding expertise in banking related matters’; cybersecurity expert Robert Silvers; and structured credit partner Richard Davis (both also based in Washington DC). Silicon Valley Bank, cryptocurrency exchange Gemini Exchange and Barclays are all clients.
