Title: Unconfirmed Transaction sent Zero Fees by Mistake Multibit HD
Post by: BTC Zebra on December 08, 2017, 11:13:07 AM
Dear All,

I have been in bitcoin for a few years and need to make a few transactions, I set up a new install of Multibit HD to transfer to.

My old version of Multibit HD sent it with I believe zero fees, this was an error and something I will be aware of for future transactions.

I sent 0.02 BTC at 22:04 last night, so it has been over 11 hours. I want to know what my best option is here, I need to get this confirmed and resend a larger transfer with a good level of fees - advice on a suitable level would be appreciated. The next transfer would benefit from some speed as a larger transfer.

If this does not confirm, what are my options there? I do have access to the sending and receiving address.

Many Thanks,

BTC Zebra

Hi,

Multibit has been discontinued...

I think your best option is to export the private keys and import them into bitcoin QT and go from there.
Can you post the sending address or TX?

Regards.

You could try to either 1) double spend the transaction with a higher fee (Replace-by-Fee) or 2) since you have also access of the recieving address, CPFP (Child pays for parent).
1) Quite a few wallets have this function build in. Bitcoin core and electrum for example.
You could import your private keys into one of these wallets and 'replace' the old TX.
2) If you plan going for CPFP then you basically have to create a new transaction spending those unspend outputs.
From either the address you sent the btc to or the change address (if you didn't send the whole amount). Make sure to include a fee which is high enough to cover the size of
both transactions. You can look for an estimated fee here: https://bitcoinfees.earn.com/ (https://bitcoinfees.earn.com/).
