Download & Setup HMY

To interact with your Ledger device using the HMYC CLI, please click here to download and configure it first.

Interacting with Ledger

With that in mind, you can run any other command via HMY CLI using your Ledger.

Below, are a few practical examples on how to interact with your Ledger device.

1. Displaying your Address

For example, if you want to show your Ledger address you would simply run:

Using the Binary:

./hmy keys list --ledger

Using the Shell Wrapper:

./hmy.sh -- keys list --ledger

2. Displaying your Balance

Using the Binary:

./hmy balances --node="<endpoint-address>" <ONE-address> --ledger

Using the Shell Wrapper:

./hmy.sh -- balances --node="<endpoint-address>" <ONE-address> --ledger

3. Sending Transactions

Using the Binary:

./hmy transfer --node="<endpoint_address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase --ledger

Using the Shell Script:

./hmy.sh -- transfer --node="<endpoint_address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase --ledger

For a complete reference of all commands available, please check the HMY CLI cookbook.

Ledger Nano X and Nano S

The Nano X and Nano S are hardware wallets created by Ledger. A hardware wallet stores the private keys to Harmony tokens on a separate device, making it much harder for malicious parties to steal them. In fact, the private keys never leave the Nano wallet itself, so they will remain secure even if the device is connected to a compromised computer. As long as you follow best practices when using your Nano, it is virtually impossible for an attacker to steal your funds.

Plug in your Ledger and open the Harmony Ledger App. Your device will be detected by your computer.

Start from the staking dashboard: https://staking.harmony.one/ledger and click the "sign-in" button.

You will be directed to the Validators page on the Staking Dashboard and a small trident logo will appear on the chrome tab. Your Ledger Nano will display "waiting for commands" before you click on any buttons.

Click the "Show on Ledger" button to display your address on your Ledger device.

Press the right button on Ledger to continue and confirm the address is correct.
