Ledger

The Lux wallet supports Ledger hardware wallets for secure key storage and transaction signing. Private keys never leave the device.

Supported Devices

Setup

1. Install the Lux app on your Ledger via Ledger Live
2. Connect the Ledger device via USB
3. Open the Lux app on the device

Usage (Go)

import "github.com/luxfi/sdk/wallet"

// Connect to Ledger
w, err := wallet.New(wallet.WithLedger())
if err != nil {
    // Handle: device not connected or app not open
    panic(err)
}

// Get addresses (derived on device)
cAddr := w.CChainAddress()
pAddr := w.PChainAddress()

// Sign a transaction (requires on-device confirmation)
err = w.Sign(ctx, tx)

Usage (Web)

1. Visit wallet.lux.network
2. Click "Connect Ledger"
3. Approve the connection on your device
4. Your addresses appear automatically

Derivation Paths

The Ledger app uses the same BIP-44 paths as the software wallet:

Security Notes

• The Ledger device displays the transaction details before signing
• Always verify the recipient address and amount on the device screen
• Never share your recovery phrase -- it is the master key to all derived addresses
• Firmware must be up to date for security patches
