Guide · ~10 minutes

Connect Ledger to Sia Wallet.

Install the Sia app on your Nano, plug in the device (or pair Bluetooth on Nano X), unlock, and sign your first Siacoin transaction — all without experimental browser flags or driver hunts.

What you need

  • A Ledger Nano S, Nano S Plus, or Nano X — already set up with a PIN and 24-word recovery seed backed up

  • Ledger Live installed and updated to the latest version (from ledger.com/ledger-live)

  • Sia Wallet v2.12.0 installed

  • A USB cable (included with your Ledger) — or Bluetooth, if using Nano X

  • Space on your Ledger for one additional app — Sia occupies a small amount; Nano S users may need to uninstall an unused app to make room

Pairing steps

  1. 1

    Update Ledger Live and your Ledger firmware

    Open Ledger Live. If there's an update banner, install it. Then plug in your Ledger, unlock with your PIN, and go to My Ledger in Ledger Live. If the device shows a firmware update available, run it — this takes about five minutes and the device will reboot. Up-to-date firmware is needed for the current Sia app.

  2. 2

    Install the Sia app on your Ledger

    In Ledger Live, go to My Ledger → App Catalog. Search 'Sia' (the token symbol SC may also work). Click Install on the Sia app entry. Installation takes about 30 seconds. The Sia app now shows under 'Apps Installed' and appears in the app carousel on the Ledger device itself.

  3. 3

    Open the Sia app on the device

    Unlock your Ledger with your PIN. Use the physical buttons to scroll to the Sia app icon. Press both buttons simultaneously to open it. The Ledger screen displays 'Sia application is ready.' Leave the app open — don't navigate away until after Sia Wallet detects the device.

  4. 4

    Launch Sia Wallet

    Open Sia Wallet. If you have no existing wallet, the first-run wizard shows 'Add Ledger hardware wallet' as one option — pick it. If you have an existing wallet, go to Accounts → Add Account → Hardware Wallet → Ledger. Sia Wallet polls for a connected Ledger running the Sia app.

  5. 5

    Sia Wallet detects the Ledger

    Within a few seconds, Sia Wallet recognises the device and shows its derivation path, associated Siacoin address, and current balance. For first-time pairing, this should be an empty wallet with balance 0 SC — that's expected. Click 'Add account' to import it into Sia Wallet as a Ledger-backed account.

  6. 6

    Set up Bluetooth (Nano X only, optional)

    If you prefer Bluetooth for Nano X, disconnect the USB cable and go to Sia Wallet Settings → Hardware Wallets → Enable Bluetooth. Put your Nano X in pairing mode (it will prompt for the app-initiated BLE pairing). Sia Wallet shows the device; confirm the pairing code on both the Ledger screen and Sia Wallet. Subsequent sessions reconnect automatically when both are in range.

  7. 7

    Send a small test transaction first

    Before moving significant balances onto the Ledger, send yourself a tiny test amount (0.1 SC is plenty) from another wallet. Verify it arrives on the Ledger account in Sia Wallet. Then try sending that 0.1 SC back — Sia Wallet constructs the transaction, sends it to the Ledger for confirmation, the Ledger screen displays 'Confirm transaction' with the recipient address and amount. Press the right button to sign. The transaction broadcasts. End-to-end verified.

Ledger pairing questions

Does the Ledger app work with an existing Sia Wallet account?

Not directly — a Ledger account derives its keys from the Ledger's own 24-word recovery seed, not from your existing Sia Wallet seed. To 'move' an existing software wallet onto a Ledger, send the balance from your software account to your new Ledger account address (an on-chain transaction). The software seed can then be archived or erased.

Can I use the same Ledger with multiple Sia Wallet installations?

Yes. The Ledger is the authority — it derives its keys from its own seed and signs with them regardless of which wallet software is asking. You can pair the same Ledger with Sia Wallet on your desktop, Sia Wallet on your laptop, and walletd's web UI, and they'll all derive the same Sia addresses from the same device.

Is Bluetooth signing as secure as USB?

The security properties are comparable: private keys never leave the Ledger's secure element, signatures are generated on-device, and transaction data sent over either connection is public blockchain data. USB gives you a physical-wire guarantee that some users prefer for maximum paranoia. Both are supported.
