Using Ledger Hardware Wallet

This guide describes how to set up your Ledger hardware wallet for managing your TAO on the Bittensor network.

Requirements​

Set up your Ledger hardware wallet as per Ledger instructions.

This guide assumes that you have a Ledger device and the Ledger Live app installed already.

Common Steps​

  1. Connect Ledger device to your computer with Ledger Live installed.
  2. Open Ledger Live app > My Ledger > Unlock Ledger > Approve Ledger Live.
  3. Install the Polkadot (DOT) app from Ledger Live.
  4. To manage your TAO from your Ledger hardware wallet, you must install a wallet app that supports TAO and also supports the Ledger hardware wallet. Talisman, Nova Wallet, and Subwallet apps satisfy this condition. Install any of these wallet apps, and make sure you have configured these wallet apps to also use the Bittensor network. This is required for either transferring TAO using your Ledger, or finding the correct address to receive TAO on your Ledger device.
Stop. Did you run the above steps?

Proceed only after you successfully ran the above steps. The rest of this guide is described using Talisman wallet app.

Step 1. Connect Talisman app to Ledger device​

  1. Connect Ledger hardware wallet device to your computer.
  2. Open Talisman wallet app and select Add Account.
