You can find your wallet details in the side menu and the ‘Wallets’ tab:

Side menu:

1. Tap the person icon in the top left hand corner of the home screen
2. Tap ‘Wallet details’
3. Select the wallet you want to view

Wallet tab:

1. Tap the ‘Wallets’ tab at the bottom of the screen

In the GBP tab you'll find your sort code and account number, in the EUR tab you'll find your IBAN. Right now wallet details are only available for GBP and EUR.
