Blocknox GmbH, a part of the Boerse Stuttgart Group, specializes in cryptocurrency custody on an escrow basis, a service that began in late January 2019 for BISON app users and was subsequently expanded in late September 2019 to include users of the Boerse Stuttgart Digital Exchange (BSDEX). The company has developed a comprehensive multilevel security framework to ensure the safe custody of digital currencies. Looking ahead, Blocknox plans to broaden its custody services to institutional clients such as fintech firms, banks, and asset managers, enabling them to utilize Blocknox’s reliable custody solutions as integral components of their own digital asset offerings. In response to the legal requirements for crypto custody that came into effect in Germany on January 1, 2020, Blocknox has taken the initiative to apply for the necessary license from regulatory bodies. While waiting for this license to be approved, the company maintains a provisional status as a regulated financial services provider, which allows it to continue functioning within the established legal framework. This proactive strategy not only enhances Blocknox's credibility but also positions it as a significant contributor in the rapidly changing realm of cryptocurrency custody solutions, where trust and security are paramount for clients and investors alike.
