HMY CLI (Harmony Command Line Interface)


hmy is the official Command Line Interface (CLI) provided by Harmony. You can use it as a local wallet and as a way to interact with your Ledger Nano device. The hmy CLI is completely open-source. You can track its development and post any issues encountered and your feature suggestions here.


With the hmy CLI you can create a wallet, check your balance, send signed transactions to the Harmony blockchain, look up previous transactions, recover keys from previous mnemonics, create new keystores, and create new BLS keys.
