Hedera (HBAR & HTS)
In order to get public key for Hedera Account, you can use
getAddress() function.If you use
DcentCLIConnector.coinType.HEDERA as a coinType parameter for getAddress() function, you can get public key for the private key of the BIP44 path.For more detail about
getAddress(), please see the below section.Transaction | Supported | Group |
