Ledger Accounts ​

Use a Ledger device so the private key never leaves the chip. The extension prepares payloads; the device approves and signs.

Connect a Ledger device ​

From Add Account > Connect Ledger (or during onboarding):

  1. Plug in the Ledger over USB.
  2. Approve the browser HID/WebUSB prompt when the wallet asks.
  3. Open the Bittensor app on the device; the wallet polls until it sees the app.
  4. Pick one or more derivation rows to import.
  5. Each row shows index, address, and balance. Use Load More or jump to a specific index.

If the browser cannot use WebUSB/HID, the wallet shows a warning with a doc link.

Confirm each signature on the device ​

Ledger-backed sends and dApp signatures open a dedicated authorization window. The wallet attaches metadata so the device screen stays readable while you approve on hardware.

Work within Ledger constraints ​

  • Ledger accounts use ed25519; default software accounts in the wallet use sr25519.
  • The device must stay connected with the Bittensor app open for every signing step.
  • Passkey unlock is wallet-level; it is not a per-account substitute for the Ledger.

Add Ledger during onboarding or later ​

First-time setup can use Load from Ledger to create the vault and import device accounts in one pass. After a wallet exists, Connect Ledger under Add Account appends more device accounts without resetting the vault.
