Installing the Helium-Solana App

Update your Ledger firmware to at least 2.1.0, perferably 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 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.

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.
