Sentinel is an Android app which lets you safely watch over your Trezor Bitcoin transactions.

Scan one or more of your account public keys with Sentinel and keep a close watch on your new incoming transactions. Sentinel also allows you to generate new receiving addresses, which allows you to accept payments directly into Trezor without the device being present. For Trezor accounts, Sentinel cannot sign transactions and send payments, so it is only useful as a watch-only wallet.

ImportantPlease keep in mind that we do not develop nor maintain third-party software, so we cannot guarantee their full functionality. However, your private keys are always safely protected by your Trezor device, no matter what third-party application you use it with.

Using Sentinel with Trezor

To import your Trezor account, you need to display your account public key (XPUB) in Trezor Wallet first. To do that, see Displaying account public key (XPUB).

Now install the Sentinel app on your android device.

1. When it opens, select Segwit Bitcoin Wallet (or Bitcoin Wallet if you are using a Bitcoin legacy account).
2. Select Scan and the QR code connected to your account public key (XPUB) in Trezor Wallet.
3. If you do not have access to the device camera, enter the address manually.
4. After you confirm it, Sentinel downloads all transactions related to the imported account.

You can get more information about the particular transaction by simply selecting it from the list. To generate a new receiving address, click on the + icon at bottom right corner. If you need to watch another account, click on the settings icon in the upper-right corner and import a new account public key.
