This webinar explores Digital Public Infrastructure for Payments as a cornerstone of modern digital economies, focusing on its implications for digital sovereignty, interoperability, and consumer protection. The discussion will examine case studies such as the Brazilian Pix and the Indian UPI, exploring how countries design payment systems that balance state coordination with openness, enabling innovation while safeguarding the public interest. Particular attention will be devoted to cross-border interoperability, including emerging solutions such as the Interledger Protocol and multi-CBDC bridges, as well as governance frameworks aimed at ensuring data protection, cybersecurity, and user rights. Bringing together policy, technical, and legal perspectives, the session aims to provide practical insights into the development of inclusive, secure, and globally connected payment infrastructures.
