About Otranto

Otranto is a full-service consultancy focusing on strategy, management, technical, and information security advisory services.

We have global delivery capabilities for developing and implementing Central Bank Digital Currency (CBDC) and Digital Financial Markets (DFMs) solutions.

What are digital financial markets?

Digital Financial Markets (DFMs) encompass the next generation of global value transfer that realigns risk. It involves modernising core financial market infrastructure (FMI) with tokenised value that may use distributed ledgers. We see “DeFi” and “CeFI,” and all iterations between complete centralisation and complete decentralisation as DFM extensions to the existing structures around the relationships in financial markets. 

DFMs use innovation to provide efficiencies and products that may have previously been uneconomic or impossible. Regulators maintain critical roles in DFMs, including supervision, monetary and financial stability, and consumer protection.


With years of experience globally and working together since 2015, John and Vincent have a wealth of knowledge in digital financial markets.
