Özet: For cryptocurrency trading, the addresses of the sender and the receiver, called public keys, are required. Transactions involving information such as the address of the sender, the address of the recipient and the shipping amount are kept according to a certain system in blocks that are connected one after another. Each address, the public key, has a unique secret key equivalent. Signatures signed with these private keys are used for cryptocurrency transactions. Since privacy is at stake, it is important and recommended to use more than one address in cryptocurrency transfer. The management and storage of these keys is provided by wallets. Offline wallets do not have direct internet access and are more secure. In this article, the topic of a hardware smart card wallet that holds keys that allow access and spending of blockchain-based cryptocurrencies, which is an offline wallet type, is discussed. BIP-32, BIP-39 and BIP-44, which offer a hierarchical and deterministic method for key generation and storage, are given in a detailed way. In the v3.0 of AKİS, the national smart card operating system, applications such as identity, passport, driver's license, e-signature and ticket can be collected in a single card. With this version, one of the applications included in the card is the wallet application. It is designed to handle Bitcoin transfer. AKİS wallet is developed to be able to perform BIP-32, BIP-39 and BIP-44 and elliptic curve cryptographic transactions.
