Crypto Finance, a subsidiary of Germany’s largest stock exchange operator, signed a deal with Commerzbank to offer trading services to the lender’s corporate clients just two weeks after reaching a similar agreement with Zürcher Kantonalbank in Switzerland. Commerzbank will provide custody services, the companies said on Thursday. The trading service offered by the Deutsche Boerse unit will be available to clients based in Germany and initially focus on trading in the two largest cryptocurrencies, bitcoin and ether. Commerzbank obtained a crypto custody license in Germany in November 2023, allowing the financial services firm to offer a wide range of services related to digital assets.
