Topic: [READ] About blockchain.info's web wallet and "stuck" transactions (Read 50605 times)

Once your transaction is sent and "stuck", there is one more thing you can do that is not covered in the OP: You can import the blockchain.info keys into a wallet that has CPFP functionality. CPFP works with all wallets that have "coin control" - including Electrum.

CPFP is only possible if your transaction has a "change" output you have control of - that means, if you didn't send all the coins of one output (or your whole balance) in that transaction but a part is "returned to your wallet".

CPFP simply means that you use the output with the "change", send it to another address (it can be one of your control) with a high fee (about double the "minimum fee" where Bitcoinfees shows an estimated confirmation time you are willing to accept). Miners would then process both transactions for the fees of the second one.

The import/export operation of wallets from blockchain.info is a bit tricky as it's a BIP39 wallet, it is covered in this guide.

Any wallet that supports "Replace-By-Fee" aka RBF... you will be able to bump the fees provided the transaction was originally marked as "RBF"

I can confirm that Bitcoin Core and Electrum both offer "Opt-in" RBF... ie. you need to use specific settings to enable it.

is there an wallet that can control fee after send ?

if i send with small fee so back and edit fee to be high

One can always refer (as i do) to bitcoinfees.21.co before sending BTC.  You will see clear picture of the fees, and can choose the most appropriet for you there.

Very nice explanation. In the past I have had trouble with the blockchain.info web wallet, in fact I even lost a small amount of Bitcoin due to some error on login / account. The main thing I really want to point out is that if you do not hold the private keys, you don't really own the coins. There are so many mobile and desktop wallets now (make sure reputable) that it seems silly to keep coins online.

Users of the blockchain.info web wallet can use this guide to export their private keys to another wallet that supports CPFP, or that can otherwise attempt a double spend once it is sufficiently likely that nodes have "forgotten" about a low fee transaction.

CPFP is dependent on being able to "spend" one of the outputs of the "stuck" transaction. It isn't really dependent on the "inputs", so it shouldn't matter how many addresses you've sent from (aside from the fact that the number of inputs is usually the main factor in transaction size, which obviously impacts on the amount of fee required for the CPFP)

Yes, both the mobile and web wallet now have a "custom fee" option that allows a user to enter a "sats/byte" amount. Small steps in the right direction I guess...

The problem with creating a CPFP from blockchain.info, is that there is no "coin control"... so there is no guarantee that any transaction they create will include an output from the parent transaction unless they choose to send ALL their coins... which is just going to drive up the transaction size (and fees required) needlessly... especially given that the majority of blockchain.info web wallet users also tend to be "cloud miners" and "faucet collectors" and already have multiple UTXOs that are more or less "dust"...

The sheer number of threads here of people not understanding why it is costing them 50% of their total balance to send their coins and then posting TXIDs that have 15-20 inputs and a transaction size best measured in kilobytes for a total of 0.005 BTC sent indicates that a lot of users simply don't understand bitcoin fundamentals.

I believe that blockchain.info has actually upgraded their software so that users can now choose the tx fee, and see both a recommended tx fee and an estimate as to when a transaction will get confirmed based on the tx fee rate.

Also, users can create a CPFP transaction provided they create a transaction with a sufficient size (in terms of BTC). 

Firstly, DO NOT POST ISSUES RELATED TO BLOCKCHAIN.INFO (including "stuck" transactions made with their wallet) HERE! If you do, your thread will be moved to the Web Wallets section.

Blockchain.info's web wallet is considered a poorly written wallet and is seemingly incapable of sending proper transactions with correct transaction fees and confirmed inputs. If you are using blockchain.info's web wallet and your transaction is stuck, it is almost definitely because the transaction fee is too low (at 120 sat/byte which seems to be blockchain.info's default fee rate even though it is much too low) or because you are spending from other unconfirmed transactions.

If you are using blockchain.info's web wallet, unfortunately you won't be able to attempt RBF or CPFP transactions as blockchain.info does not provide the advanced functionality to make those transactions. All you can do is ask miners for help and wait. For asking miners for help:

To avoid this problem in the future, stop using blockchain.info. Instead switch to any wallet listed on Bitcoin.org and has one of the following texts regarding how the wallet handles transaction fees:
Any wallet which has one of these texts for in their descriptions (with the color and bolding) will support dynamic fees and allow you to make transactions with proper fee rates.
