Title: Unconfirmed transaction
Post by: bestcoffee on June 13, 2017, 01:16:34 PM

sent some btc to my online wallet and didn't realise the fee didn't adjust automatically and sent it as is.. I tried using viabtc but it says "submission too long - try again later". Any way someone could help me process it or do I just wait for it to be forgotten? Will it take longer than a week if Im using Armory wallet? Thanks in advance for the help!

For ViaBTC, you need to submit in the first 30 seconds of a new hour. They only have 100 slots per hour, and they fill up fast!

Hard to predict how long before it drops... it used to be around 72 hrs... then a lot of nodes stretched out to 336 hrs (14 days). Also, if your wallet rebroadcasts it could theoretically never drop... I'm not sure if Armory automatically rebroadcasts or not.

You could always try a CPFP seeing as you sent the coins to yourself... (or maybe an RBF if Armory supports it)

Il try to catch the next hour I guess!
On armory I cleared unconfirmed transactions, if I send it again with a higher fee will it possibly get confirmed before the original tx?

yes, if you re-use the same unspent outputs as you used for the stuck transaction and broadcast the new (double spending) transaction, there is a reasonable chance it will confirm before the stuck transaction... The only problem seems to be that a lot of nodes reject the new transaction, but you shouldn't worry about this.

Only one input, sequence = 4294967295, so this one wasn't opt-in RBF ;)

Is CPFP still an option?

Yes, since you are both the sender and the receiver, both CPFP and double spending the unconfirmed inputs for the stuck transactions would be a viable option for you... However, you told us that you were sending from armory to your online wallet: not all wallets will allow you to create transactions using inputs that were received as an output of an unconfirmed transaction.

So, wether or not CPFP will work for you depends on which online wallet you are using (unless your online wallet allows you to export your private keys, in that case you can export them and import them into a (new) core wallet and create a CPFP using core...
