On this page 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.](https://docs.helium.com/wallets/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.](https://support.ledger.com/article/360016265659-zd) Remember to configure [blind signing.](https://support.ledger.com/article/4499092909085-zd) ## Basic Setup Guide Using Helium Black Wallet App and Ledger 01.

On Black Wallet App, tap the pub key / address above the wallet balance to copy your pub key to clipboard 24. Save your wallet pubkey somewhere handy, this is destination for transfers into your cold wallet. ## 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 Transfers out of your wallet will require SOL to pay fees, so start by adding a 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 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 you 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.](https://support.ledger.com/article/7723954701469-zd) 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](https://docs.helium.com/wallets/third-party-wallets#importing-helium-accounts-into-solana-wallets) documentation. ## Ledger Helium L1 to Solana Migration If you have an unmigrated Ledger wallet that existed on the Helium L1 prior to the migration to Solana on April 18th, 2023, you will need to follow these instructions. ### Video Walkthrough Ledger Migration Helium to Solana - YouTube [Ledger Migration Helium to Solana](https://www.youtube.com/watch?v=Sl7UBStRmpA) ### Installing the Helium-Solana App Update your Ledger firmware to at least 2.1.0, preferably 2.4.x before you start. As of now, we are still waiting on Ledger to release our app. Until then, to install you must follow these steps: 1. Open Ledger Live. 2. Go to Settings (top right corner) 3. Click `Experimental Features` 4. Enable `Developer Mode` 5. Install the [Helium-Solana Ledger App](https://github.com/helium/app-helium-solana) as you normally would. 6. Close Ledger Live ### 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](https://github.com/helium/app-helium-solana) now available from Ledger Live (ensure Developer Mode is enabled) - [Solana Ledger App](https://support.ledger.com/article/360016265659-zd) using Ledger Live **Before starting these steps, close the Ledger Live application or the transactions will fail.** 1. Connect Solana Ledger Open the Solana App on your ledger. Be sure to [enable blind signing](https://support.ledger.com/article/4499092909085-zd) in the Ledger Settings. Select the account number you would like to migrate. Then click the button below. Account Number 2. Connect Helium-Solana Ledger Open the Helium-Solana App on your ledger. Be sure to [enable blind signing](https://support.ledger.com/hc/en-us/articles/4499092909085-Allowing-blind-signing-in-the-Solana-SOL-app?support=true) in the Ledger Settings. Then click the button below. 3. Keep Helium-Solana Ledger Connected and Seed Wallet on Solana Seed your tokens and hotspots into your Solana wallet 4. Sign Transactions with Helium-Solana Sign transactions to migrate from the Helium derivation path to the Solana derivation path. 5. Sign Transactions with Solana Open the Solana Ledger app. Sign transactions to migrate from the Helium derivation path to the Solana derivation path. 6. Send Migration Transactions I attest that both the source and destination wallets are owned and controlled by the same individual or entity, and that I have legal authority to perform this transaction on behalf of that individual or entity. ### 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.
