The cryptocurrency trading has gone viral in recent years. Major well-known cryptocurrency exchanges, such as Binance, FTX and Coinbase, have attracted cryptocurrency holders by providing easy-to-use cryptocurrency wallets and diversified services. However, such convenient services are achieved by hosting the private key of the client’s cryptocurrency wallet. Once the exchange is hacked and breached, the hackers obtain the customers’ private keys, bringing heavy losses to the customers. In order to prevent such problems, more and more users have begun to embrace hot wallets and cold wallets, among which the latter are considered to be more secure.A cold wallet, also known as a hardware wallet, is a device for offline storage of private keys. It generates and stores the private keys of cryptocurrency wallets through an offline hardware environment, reducing the risk of hackers stealing the private keys. Therefore, for different currencies of different blockchains, the hardware wallet needs to support the transaction format of the currency, such as the hash function and digital signature algorithm used, otherwise the signature of the transaction cannot be generated. In order to accelerate the speed of hardware wallets supporting new currencies, this study believes that the efficiency of implementation can be improved by implementing transactions on the Ethereum-compatible chains. First of all, this study uses the hardware wallet provided by CoolBitX to implement the transactions of Avalanche C-Chain, an Ethereum-compatible chain. After extracting the differences between Avalanche C-Chain and Ethereum transactions, we develop the Ethereum compatible chain structure, according to which the transactions on Aurora and Klaytn are implemented, and the process difference between the old and new method is compared. Under the Ethereum-compatible architecture, only two steps are needed in the future to enable the hardware wallet to support transactions on the new chain. Compared with the current method, the implementation process is greatly shortened.參考文獻 Aung, Y. N., & Tantidham, T. (2017).
