Ledger Nano
This page describes how to use a Ledger Nano S or Nano X to interact with Renec using the command line tools. To see other solutions to interact with Renec with your Nano, click here.
Before You Begin#
Use Ledger Nano with Renec CLI#
- Ensure the Ledger Live application is closed
- Plug your Nano into your computer's USB port
- Enter your pin and start the Renec app on the Nano
- Ensure the screen reads "Application is ready"
View your Wallet ID#
On your computer, run:
This confirms your Ledger device is connected properly and in the correct state to interact with the Renec CLI. The command returns your Ledger's unique wallet ID. When you have multiple Nano devices connected to the same computer, you can use your wallet ID to specify which Ledger hardware wallet you want to use. If you only plan to use a single Nano on your computer at a time, you don't need to include the wallet ID. For information on using the wallet ID to use a specific Ledger, see Manage Multiple Hardware Wallets.
View your Wallet Addresses#
Your Nano supports an arbitrary number of valid wallet addresses and signers.
To view any address, use the renec-keygen pubkey command, as shown below,
followed by a valid keypair URL.
Multiple wallet addresses can be useful if you want to transfer tokens between your own accounts for different purposes, or use different keypairs on the device as signing authorities for a stake account, for example.
All of the following commands will display different addresses, associated with the keypair path given. Try them out!
- NOTE: keypair url parameters are ignored in zsh see troubleshooting for more info
You can use other values for the number after key= as well.
Any of the addresses displayed by these commands are valid Renec wallet
addresses. The private portion associated with each address is stored securely
on the Nano, and is used to sign transactions from this address.
Just make a note of which keypair URL you used to derive any address you will be
using to receive tokens.
If you are only planning to use a single address/keypair on your device, a good
easy-to-remember path might be to use the address at key=0. View this address
with:
Now you have a wallet address (or multiple addresses), you can share any of these addresses publicly to act as a receiving address, and you can use the associated keypair URL as the signer for transactions from that address.
View your Balance#
To view the balance of any account, regardless of which wallet it uses, use the
renec balance command:
For example, if your address is 7cvkjYAkUYs4W8XcXsca7cBrEGFeSUjeZmKoNBvEwyri,
then enter the following command to view the balance:
You can also view the balance of any account address on the Accounts tab in the Explorer and paste the address in the box to view the balance in you web browser.
Note: Any address with a balance of 0 RENEC, such as a newly created one on your Ledger, will show as "Not Found" in the explorer. Empty accounts and non-existent accounts are treated the same in Renec. This will change when your account address has some RENEC in it.
Send RENEC from a Nano#
To send some tokens from an address controlled by your Nano, you will need to use the device to sign a transaction, using the same keypair URL you used to derive the address. To do this, make sure your Nano is plugged in, unlocked with the PIN, Ledger Live is not running, and the Renec App is open on the device, showing "Application is Ready".
The renec transfer command is used to specify to which address to send tokens,
how many tokens to send, and uses the --keypair argument to specify which
keypair is sending the tokens, which will sign the transaction, and the balance
from the associated address will decrease.
Below is a full example. First, an address is viewed at a certain keypair URL.
Second, the balance of that address is checked. Lastly, a transfer transaction
is entered to send 1 RENEC to the recipient address 7cvkjYAkUYs4W8XcXsca7cBrEGFeSUjeZmKoNBvEwyri.
When you hit Enter for a transfer command, you will be prompted to approve the
transaction details on your Ledger device. On the device, use the right and
left buttons to review the transaction details. If they look correct, click
both buttons on the "Approve" screen, otherwise push both buttons on the "Reject"
screen.
After approving the transaction on your device, the program will display the transaction signature, and wait for the maximum number of confirmations (32) before returning. This only takes a few seconds, and then the transaction is finalized on the Renec network. You can view details of this or any other transaction by going to the Transaction tab in the Explorer and paste in the transaction signature.
Advanced Operations#
Manage Multiple Hardware Wallets#
It is sometimes useful to sign a transaction with keys from multiple hardware wallets. Signing with multiple wallets requires fully qualified keypair URLs. When the URL is not fully qualified, the Renec CLI will prompt you with the fully qualified URLs of all connected hardware wallets, and ask you to choose which wallet to use for each signature.
Instead of using the interactive prompts, you can generate fully qualified
URLs using the Renec CLI resolve-signer command. For example, try
connecting a Nano to USB, unlock it with your pin, and running the
following command:
You will see output similar to:
but where BsNsvfXqQTtJnagwFWdBS7FBXgnsK8VZ5CmuznN85swK is your WALLET_ID.
With your fully qualified URL, you can connect multiple hardware wallets to
the same computer and uniquely identify a keypair from any of them.
Use the output from the resolve-signer command anywhere a solana command
expects a <KEYPAIR> entry to use that resolved path as the signer for that
part of the given transaction.
Troubleshooting#
Keypair URL parameters are ignored in zsh#
The question mark character is a special character in zsh. If that's not a
feature you use, add the following line to your ~/.zshrc to treat it as a
normal character:
Then either restart your shell window or run ~/.zshrc:
If you would prefer not to disable zsh's special handling of the question mark character, you can disable it explictly with a backslash in your keypair URLs. For example:

delegating stake. You can use your Ledger keypair URL
anywhere you see an option or argument that accepts a <KEYPAIR>.
