Tangany started in September 2018 and is since then financed by the German Federal Ministry of Economics for being a Deep-Tech startup. After a phase of product evaluation and market research, the final product has been designed. The product was released in March 2019, which enables businesses to easily use blockchain technology. Our solution 'Wallet as a Service' provides an API which makes it accessible to create and store private keys in the cloud and to sign transactions. The solution is a huge time and budget saver and also allows companies to create real usable blockchain products. First customers are successfully using the solution from overall of the EU.
