In the end, I left min_confirmations in getBalance too, just to be consistent, thinking that we would change everything together in another PR. Shall we change it here too? Or separate PR?

@AntonioVentilii-DFINITY oh! yeah in another PR. No need to add anything in CHANGELOG as it is not yet released but for separation of concern, let's split in another PR. Works for you?
