description: The topic of the graduate qualification work is Â«Research security of Polkadot crypto walletsÂ». The purpose of the study is to create protection against the identified vulnerability in Polkadot cryptocurrency wallets. The subject of the work is vulnerabilities in implementations of Polkadot crypto wallets. The research set the following goals: 1. Studying crypto wallet of perspective cryptocurrencies. 2. Studying the possibilities of obtaining a mnemonic phrase in the implementation of wallets for promising cryptocurrencies. 3. Studying the possibility of adding data to protect crypto wallets in the Polkadot blockchain. 4. Developing protection against the detected vulnerability. During the work a vulnerability of loss of access was detected, when restoring a Polkadot account from a backup file, and possible methods of protection were also investigated. As a result of the work, a mechanism was developed and implemented to protect against the vulnerability of loss of access, when restoring a Polkadot account from a backup file. It was concluded that the proposed mechanism allows protecting all Polkadot crypto wallets against the identified vulnerability. The results obtained can be used as a basis for developing backup and account recovery protection for all Polkadot crypto wallets.
