User manual:Displaying account public key (XPUB)
This article provides instructions to display the account public key in Trezor Wallet.
Trezor Wallet should now display your XPUB both as a QR code and as text. If you use multiple accounts, click on the relevant XPUB to show its QR code. Scan it into an application that supports XPUBs. Then, you can watch your transactions and receive payments everywhere without carrying your Trezor. Be careful with your account public keys (XPUBs). When you expose these to a third party, you allow them to see your entire transaction history.
