The extended public key, or xPub, describes your Bitcoin account. Bitsurance uses it to assign the addresses and balances you want to insure. Private keys or your 24 words are never transferred.

Ledger Live stores the xPub locally for every account you add in Ledger Live. The xPub cannot spend Bitcoin, but it can reveal the addresses and transactions of this account.

Show the xPub in Ledger Live Desktop

1. Open Ledger Live.
2. Select Accounts and open the Bitcoin account you want to insure with Bitsurance.
3. In the account, click the wrench icon or account settings.
4. In the Edit account window, expand Advanced logs.
5. Copy the displayed xPub. Make sure you only copy the key itself.
6. Paste the xPub into the xPub field in the Bitsurance registration flow.

Choose the correct account

Every Ledger Live account has its own xPub. Make sure you select exactly the Bitcoin account whose coins you want to insure. If you created an additional account for Bitsurance, use the xPub of that additional account.

Use a SegWit or Native SegWit account. Taproot addresses are currently not supported in the Bitsurance registration flow.

Important: Never share your 24 words, seed phrase, or private keys. An xPub cannot spend coins, but it is privacy-sensitive because it can be used to track account activity.
