How long would it take to confirm a 1 sat/vB transaction?
24+ hours? Has anyone tried it for consolidation?
I tried a 1 sat/vB consolidation as an experiment a month or so ago using a pruned node just to see if it will work and how long it would take.
Blockchain explorers still show it as unconfirmed. My node is still running. The transaction is composed of more than 50+ dust UTXOs
Do unconfirmed month old transactions still get confirmed if ever fees get low enough a month after? Or is a rebroadcast needed?
It depends on the wallet software. I have tried something similar with blue wallet and every time the transaction was dropped from the mempool it was instantly resubmitted automatically. Eventually after 6 month it was confirmed when there was a timeframe where fees went to 1 sat/vByte.
So you can simply try it and wait for it to get confirmed. Just check that it is not thrown out of the mempool and if it is just resubmit it.
