blocknox GmbH is the custodian of Boerse Stuttgart Group for digital assets. The subsidiary of Boerse Stuttgart Digital Ventures GmbH established its custody service for cryptocurrencies on an escrow basis in 2019 for users of the BISON app and of Boerse Stuttgart Digital Exchange (BSDEX). At blocknox, a multilevel security concept has been developed and implemented. In the future, blocknox will offer custody services for cryptocurrencies and other digital assets to institutional clients such as fintechs, banks and asset managers. They can use blocknox’s reliable custody as a building block for their own services around digital assets. With regard to the legal regulation of crypto custody in Germany, blocknox has submitted its application for the required licence to the supervisory authorities. Until the licence is granted, blocknox already has the provisional status of a regulated financial services provider.
