Qtum (QTUM)

1. Open My Ledger in Ledger Live.
2. Connect and unlock your device.
3. If asked, allow My Ledger to access your device.
4. Find QTUM in the app catalog.
5. Click the Install button of the app.
   
   
   
    The Qtum app is developed and supported by Ledger.

The QTUM app can export your extended public key (xpub) to web apps in a U2F compatible web browser (Chrome, Opera or Firefox). The xpub is privacy-sensitive information, as all public addresses can be generated from it.

Public key exports by default require manual approval on the device to prevent inadvertent sharing of your public addresses. This setting can be configured as follows:

1. Open the QTUM app.
2. Navigate to Settings > Public key export approval.
3. Choose one of two options:
   • Manual approval (default): public key exports require a confirmation on the device.
   • Auto approval: public key exports are automatically approved.

When you add Qtum accounts in Ledger Live, the address format is set to SegWit by default. If you need to receive QTUM on older address formats such as Legacy, you can change the default address format.

To change the default address format:

1. In the Add new account section of the Accounts step, click on the Show all address types toggle.
   
2. Select one of the following address formats:
   • Segwit (by default): SegWit addresses start with an M. The SegWit upgrade reduces network fees, speeds up transaction signing on hardware wallets, and enables second-layer solutions like Lightning Network. This address format will be implemented in Ledger Live.
   • Legacy: Legacy addresses start with a Q. This is QTUM's legacy address format. New Legacy accounts can now be added directly in Ledger Live. You no longer need to use a third-party wallet to add Legacy accounts in Ledger Live.

Bech32 addresses start with qc1. These are native SegWit addresses that feature safety and security improvements. This address format will be implemented in Ledger Live.
