Control Center imports **public** keys (xpubs) only. Your coins stay on your wallet. Nothing can be spent. ## What you need | Wallet | Connects by | You also need | Address types | | - | - | - | - | | **Ledger** | USB | The **Bitcoin** app open.

See [Bitkey](https://help.hoseki.app/bitcoin-control-center/accounts/bitkey.md). Other wallet or address type? Use an [xpub or descriptor](https://help.hoseki.app/bitcoin-control-center/accounts/xpub-and-descriptors.md) instead. > [!WARNING] > > Wallet scans only list accounts with a balance above zero. A new or emptied wallet shows "No wallets found" (Ledger) or "We were unable to find any accounts with a non-zero balance" (COLDCARD, Keystone). To track it anyway, add it by [xpub or descriptor](https://help.hoseki.app/bitcoin-control-center/accounts/xpub-and-descriptors.md). ## Add a hardware wallet Every wallet follows the same three stages. ```mermaid theme={null} flowchart LR A["1.

If the balance looks wrong, add the wallet by [descriptor](https://help.hoseki.app/bitcoin-control-center/accounts/xpub-and-descriptors.md) with the right address type. ## After you add it The new account syncs. Large wallets take longer. ![New account syncing in the Accounts list](https://mintcdn.com/hoseki-corp/XCQqCRepRDP5H4K0/images/accounts-syncing.png?fit=max\&auto=format\&n=XCQqCRepRDP5H4K0\&q=85\&s=3a0213e580fe9d90818ee96a88170615) Syncing a new account. * Balance looks wrong? See [Troubleshooting](https://help.hoseki.app/bitcoin-control-center/help/troubleshooting.md#balances). * Stopped before signing? The account stays **pending**.
