The answer to this other question has some information about reattaching and promoting a transaction that has been pending for a long time.
Sometimes however that does not result in the confirmation of a transaction.
So I have a couple of questions about what could be done in that sort of situations:
- The top-rated answer to this question mentions pushing "a new zero-valued transaction that approves your transaction". What would be the steps for doing this?
- Other than that, does the IOTA ecosystem provide mechanisms for debugging a transaction?
