In the app, go to Me > Settings > Profile > Bank account, enter your IBAN and tap Add. Only IBAN is supported. You can also add your IBAN when you request a payout (via Add bank account under Pay out).
Want to change your account? First remove the old account, then add the new one.
Your IBAN is only used to pay money into your account, never to take money from it.
