Abstract: The claimed solution relates to a method of making transactions in the blockchain framework using a protected hardware and software complex to ensure secure storage of digital currencies (cryptocurrencies) and control the entire lifecycle of multiple wallets simultaneously to make transactions in the blockchain network. Basic features of the hardware and software complex include the effective control over the entire life cycle of cold wallets, generation of digital wallets and secure storage of their private keys in an isolated environment using the hardware security modules (HSM), as well as maintaining the multiple level authentication of blockchain transactions. It is possible to use all the features of the complex due to compatibility with the application programming interface (API), which enables to integrate the complex into the existing software solutions, for example, banking systems.

Abstract: The proclaimed solution is related to the method of implementation of transactions in blockchain infrastructure with the protected device for safe cryptocurrency storage. This solution is directed to resolving the technical problem, which presents elimination of the existing disadvantages and offers the extended by functions hardware wallet for the cryptocurrency storage, which has an improved protection degree from the unauthorized access to the identification information of the user's account and its use for the implementation of transactions in the blockchain infrastructure.
