As the Argentine financial and capital market ecosystem continues to expand and evolve, our team provides clients with practical, comprehensive, and real-time advice to mitigate risks arising from a dynamic regulatory environment, including the Virtual Asset Service Provider (VASP), tokenization, digital payments and consumer credit regimes.
Our Fintech practice works seamlessly with the Firm’s other practice areas, including capital markets, anti-money laundering, tax, labor, corporate/M&A, intellectual property, data protection, foreign exchange and consumer protection, advising entities regulated by the Argentine Central Bank, the National Securities Commission (CNV), and the Financial Information Unit (UIF).
