Wallet integration - where can I find my xPub Key?

xPub is an extended public key from which all associated public keys or recipient addresses (but not private keys) can be derived. With an xPub you can read all addresses and therefore all transactions from a wallet, but you cannot make any transactions. So with xPub you don't get access to your coins, but only the possibility to see all transactions of a wallet.

Here you can find instructions how to get the xPub key for the most common wallets.

Hardware Wallets

Ledger Nano

1. Launch "Ledger Live"
2. Under "Accounts" click on the desired Bitcoin account
3. Click on the tool icon in the upper right corner
4. Open "Advanced Logs"
5. Find and copy the entry that starts with xpub, like xpub6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz 
   1. The import from a ledger wallet still needs a small "hack"
      
      

      Ledger always outputs the prefix "XPUB" for accounts from so-called Segwit addresses (starting with 3) as well as for accounts from Native Segwit addresses (starting with bc1). (=first 4 digits)

      Actually Segwit should start with YPUB and Native Segwit with ZPUB.

      - If you find 84' in the "freshAddressPath", then change the prefix of the extended public key from the field "xpub" to "zpub" (i.e. the first letter of the key 'x' to 'z').
      - If you find a 49' in the "freshAddressPath", then change the prefix of the Extended Public Key from the field "xpub" to "ypub" (i.e. the first letter of the key 'x' to 'y')

      A separate mask for ledger imports is in the works. This will then perform the above described in the background.
