Unfortunately, the library doesn't have a function to calculate the change from an unbalanced transaction. There is a private function under txbuilder, _add_change_and_fee
, but it relies on private fields in the txbuilder, so it is hard to use it without txbuilder.

txbuilder is the ultimate interface that helps you to automatically compute change and tx fee. I don't think there is a more straightforward way than using txbuilder itself to provide change and fee computation.

Hey I started to roll my own transaction builder to address edge cases that kept coming up. It has a lot to do with utxos with low balances that I'm wrestling with, including a problem of blockfrost sending multiple utxos for the same transaction id if a token was minted, no doubt reflecting the lovelace dumped in a token but still creating code complexities of what's available and what to return. I'm deep in this rabbit hole now.. i've kept my original createtx function that uses your builder so will respond with the code to reproduce in some time.
