We are SEBA. Technology and Finance, in real time.

The perfect symbiosis of Technology, Blockchain and Banking – we at SEBA Bank pursue the mission of redefining finance for the new economy by building a pioneering technological bridge between the digital and traditional asset worlds.

With a FINMA banking and securities dealer licence, SEBA Bank is able to close an important gap between the new digital economy and traditional banking. We believe that the proliferation of Distributed Ledger Technology (DLT) is leading to the formation of new markets and innovative ways of creating value. Therefore, we combine technological advances with the proven elements of traditional banking. Regulation is crucial for the protection of investors – the idea of an integrated and supervised bank with focus on digital assets arose from the growing demand for investment alternatives and the increasing affinity for technology and process engineering.

SEBA Bank enables professional individuals and companies as well as institutional clients to invest, safely keep, trade and borrow against digital and traditional assets, all in one place. For Swiss Blockchain companies SEBA will provide accounts and custody for fiat and digital assets. SEBA’s team aims to redefine finance and set new standards for security, transparency and performance. It consists of experts in the area of technology, information security, blockchain and finance.

Who are the People at SEBA Bank?

Our team represents a balance of genuine expertise in technology, information security and the crypto economy, coupled with banking talent that have been at the forefront of innovation in the industry.
