Ledger Hardware Wallet

The Helium tokens have support for Ledger Hardware Wallets via the Solana blockchain. Ledger allows for:

• Viewing account address(es) and balances
• Transferring tokens
• Signing transactions

At this time, Hotspot management actions such as onboarding or asserting location are not supported. You will need to perform these actions within the Helium Wallet App.

Helium HNT, MOBILE and IOT are Solana SPL tokens and are supported by the Solana App for Ledger but not directly in Ledger Live.

Installation instructions for the Solana App are on Ledger Solana support page. Remember to configure blind signing.

Testing your Ledger Cold Wallet

Before making any significant transfers into your new Ledger wallet, it is best to make a series of test transfers in and out of your wallet.

1. Open the Helium Black Wallet App on your smartphone

2. Navigate to your Ledger Wallet from steps above

3. Copy the pub key of your Ledger Wallet

4. Make a test transfer of SOL into your new Ledger Wallet

   tip

   Transfers out of your wallet will require SOL to pay fees, so start by adding at little SOL e.g. 0.1 SOL to your wallet.

5. Copy the pub key of an external wallet (either Coinbase or other Black Wallet App native wallet)

6. Make a test transfer of SOL out of your new Ledger Wallet

   note

   This will require your Ledger to be PIN unlocked and Solana App started and "ready" to complete

7. Review and Approve the transaction on your Ledger Device when prompted

8. Repeat the Process with HNT or IOT again with small amounts

9. After your have tested transfers in and out of your Ledger wallet, you are ready for safe cold storage using your Ledger Wallet.

Using Third Party Wallet Apps

Users may alternatively use Solflare or Phantom to access SOL/SPL tokens with Ledger.

Solflare, Phantom and other non-custodial wallets can import the private key from the Helium Wallet App. Follow the instructions on our using Third Party Wallets documentation.

Installing the Helium-Solana App

3. Click Experimental Features
4. Enable Developer Mode
5. Install the Helium-Solana Ledger App as you normally would.

Migrating

The following utility will migrate all tokens from the Helium derivation path 44'/904'/n'/0' to the Solana derivation path 44'/501'/n'/0'.

Ledger users will need to update their Helium Ledger App to a version that's pending release. This upcoming version will use the Solana private key derivation path that moves all your tokens and balances over to Solana. You may need to uninstall any Solana Ledger Apps during the Wallet migration process.

---

Migration Tool

Your public key will change on Solana, but the private key will remain the same. Note this app only works with Chrome, Brave, or other Chromium-based web browsers.

• Helium-Solana Ledger App now available from Ledger Live (ensure Developer Mode is enabled)
• Solana Ledger App using Ledger Live

Close Ledger Live

Before starting these steps, close the Ledger Live application or the transactions will fail.

Derivation Paths and your new Public Key

The Helium Ledger App uses ED25519 keys, similarly to Solana, but at a different derivation path.

This means that, while seed phrases are the same, private keys are different on Solana.

In order to get around this, when you run the migration, the migration application will ask you to use the old derivation path to approve sending all of your Hotspots, tokens, etc. to the new derivation path.
