“SUPER HOW?“ in the Central Banking Community: a Prototype POI Implemented by the Lithuanian Company – Among the Best


This spring the team of innovation lab SUPER HOW? took part in the Bank for International Settlements (BIS) Innovation Hub London Centre’s TechSprint on central bank digital currencies (CBDC) use case prototyping, which utilised API functionality of  “Project Rosalind”. A dedicated, small team of engineers from “SUPER HOW?” produced four CBDC use cases packed into one prototype.

In the last couple of years, central banks working on CBDC have advanced from the research and investigation phase into prototyping, which addresses actual use cases. In this context, the “SUPER HOW?” team has developed a so-called point of interaction (POI) for four use cases in one proof of concept (POC).

“I could not be more proud of our exceptional team, whose professionalism has truly shone through. Drawing upon the experience gained from our prior collaboration with esteemed institutions such as the European Central Bank and the Bank of Lithuania in the digital euro developments, our team has demonstrated remarkable expertise. Our knowledge and abilities in the rapidly changing world of digital payment transformation and financial innovations, which are currently grabbing the attention of the industry, have been further enhanced by our recent participation in the BIS Rosalind TechSprint. These invaluable experiences have established us as pioneers in this exciting field,” says Andrius Bartminas, Co-Founder and CEO of “SUPER HOW?”.

23 teams took part in the Rosalind TechSprint, with selected teams presenting their solutions to a group of central banks at a demo day event. “SUPER HOW?” was selected as one of the three teams identified by the audience on the basis of originality, completeness and quality of presentation.

“It was a sprint indeed – from the initial ideation to implementation in a very short period. This is how central bank innovations should be carried out: multiple trials, prototypes, tests and, dare we say it, failing. Early CBDC implementations around the world have proved one thing – it is not the technical brilliance or narrowly defined policy objectives that make a particular digital currency solution a success. Answering the question of whether it effectively solves a very particular problem for the consumer in a user-friendly fashion is the ultimate criterion for success. Thus, we hope that the use cases we identified in the TechSprint will inform actual implementations in the broader central banking community. I would also like to use this opportunity to thank the organisers for their splendid organisation, their professionalism, and their contribution to fostering financial innovations.“ – said Dr Marius Jurgilas, SVP of Research and Innovations at “SUPER HOW?“ who was leading the project.

Before joining “SUPER HOW?” Marius Jurgilas led the BIS Innovation Network CBDC working group and was a member of the ECB High-Level Task Force of the digital euro.

“What we see when talking to partnering institutions is the clear focus to develop compelling use cases of CBDC in payments and other contexts. Systems for tokenised securities transactions and settlements present a highly intriguing application case. The team of “SUPER HOW?” is currently working on the “Axiology” project that aims to develop a regulatory-compliant infrastructure within the scope of the European Union DLT Pilot Regime Regulation. Settlement of tokenised securities requires a tokenised settlement asset. We hope to be able to share more on this exciting project soon,” said Dr M. Jurgilas.
