[Tutorial] BlueWallet - Bitcoin Wallet Discussion

[satscraper]

With recent update, app is opening in kind of like split screen mode [1]. I thought it may be glitch so uninstalled and reinstalled but it persists, now I am wondering if it's my device thing or app is actually bugged!?

I am using version 7.1.6, which I assume is the newest version, and I don't see that split screen visible in your screenshot. There is no 'Transactions' section at my end at all. Transaction data only becomes available if I open one of my funded wallets. I threw a quick look at the settings to see if there is an option to enable/tick something like what you are seeing but I couldn't find anything. The bug must be related to specific devices only.

Yeah, on Android the latest release is 7.1.6, while the desktop version is still at 7.1.5 ^{a bit of an odd numbering choice}.

I'm using the two-years old OnePlus Nord 2T running OxygenOS 14.0, and I don't see the split screen effect either. So you're probably right and the bug could be a device-specific issue.

yesterday the new 7.1.8 version of the Blue wallet was released
this version includes lots of bug fixes as well as the following new features such as 'search for addresses/transactions'

@Pmalek, I have not found a single similar case, which means that it is still something specific related to the smartphone model that I have. I looked at their github and this example is closest to the problem I have. What's interesting is that when I go to the RBF option, the fee change window is fully functional.

What we can notice is that here all options are in one window, and it would be logical that this is also the case with the initial selection of the fee.

It seems that the guys from BW are reading this topic, because with this last update they did exactly what is shown in the picture - finally, I can choose a custom fee without any problems. I hope they don't break anything with the next update.

They show a short video on their X profile of how the new search feature works > https://x.com/bluewalletio/status/1922331152464949551
You can also make a search based on your address labels.

Another thing was added to the custom fee entries that wasn't there before. You could only enter round numbers as fees before, but now you can add decimal points if you want. I am glad it's improving.

I never noticed this, very good improvement, because with Sparrow I am always using decimal fee rate.
However, on iOS, it still doesn't work always. I tried setting it to 5.2 in a transaction, but the status of the transaction shows 5 instead of 5.2
Anyway.

It seems OK on my end. I set a custom fee of 1.3 sat v/Byte just to see if the wallet will accept it and it displays it correctly. However, I didn't create and broadcast a transaction to see if it will stay like that until the end. Make sure you use a dot and not a comma for your decimals.



Are you on Blue Wallet version 7.1.8?

It seems to work (I am using version 7.1.8 ).  I was not going to send a transaction, but then I decided to try it out, so I put in 3.56 sats per vbyte and it kept the rate that I chose (with the two decimal places), while previously it would allow me to put in the number with the decimals but as soon I would entered it, then the amount would round it down to an even number, so it would have had probably had rounded down to 3 sats per vbyte and it would not have had accepted any decimals.  

Based on current fees that are going through, I might have to wait 12-24 hours for this transaction to clear.  Perhaps?

In regards to coin control, I am bothered by the sending the full balance. The blue wallet says "Max" and it does not show the amount being sent on that initial screen, even though on the next screen, when I go to send it, then it will show the amount that I am sending.. but the showing of the "Max" is confusing for me until I get to the next screen to confirm the amount.

Edited to clarify that I am using version 7.1.8.  By the way, I see the fees are going up a lot now (between 20-30 sats per vbyte at the lowest), so at this rate, it could take several days for my 3.56 sats per vbyte transaction to go through.. it was a spontaneous test, anyhow, and going to a location that is not in-a-hurry.

I appreciate your responses guys, the answer is simple. I hadn't updated the app properly (I don't know why). I was on version 7.1.5, which explains my issue. Sorry for causing any confusion.

I'm a level above you regarding the BlueWallet version. If you are on the previous version 7.1.5, I am on version 7.1.6 on iOS.
After updating to version 7.1.8 on my iPhone, the difference is very noticeable in the fee settings section which can be costumed by tapping the iphone screen on the words Insert fee.

I am pretty sure that your transaction confirmed by now. There was a spike in unconfirmed transactions last night (EU time) but those have already been confirmed. Blocks are already being mined with transactions paying fees from 1-2 sat/vByte.

In regards to coin control, I am bothered by the sending the full balance.

I agree with you. This is unusual. I haven't noticed it before but I went to check and I can confirm that I am seeing the same thing as you. If you select to spend the entire balance, the initial screen only says "Max" and you don't see how much BTC you are sending. The same thing happens if you use coin control spend an entire UTXO.

Yep.  Sometimes we cannot be sure during a seemingly price spike how long such price spike is going to last, and even some of us might have been traumatized by various past price spikes in which the fees go up, but then they don't come back down for several months, so then it can be uncomfortable having a transaction pending for so many months, even if we are sending it to a friendly party.

So in the case of my transaction, I sent it towards the beginning of yesterday's price spike, yet it ended up confirming in less than 5 hours.  I cannot determine exactly, though I know that I already sent it at the time of my post, and I can see when it was confirmed in a block.

Personally, I would prefer the amount to be shown (along with showing Max) since they are trying to show that all of the coins are going to be spent, and sure at the bottom of the screen on that first screen, I can see how many UTXOs I had selected in the event that I had used coin control, which reminds me that I might want to consolidate some of those UTXOs.. I do find the coin-control user-interface to be more friendly through Trezor suite as compared with BlueWallet.

I am OK with the info "MAX" being displayed on the screen but you should also be able to see the amount.

Trezor Suite has done a good job in that regard. The coin control feature isn't activated by default, but once you click on it, you see all your inputs in one list. After that, it's easy to go through them and select which ones you want to spend. I don't find Blue Wallet's coin control bad either.

Both wallets do a better job than what I remember Ledger doing with Ledger Live. I haven't used it in a long time so I don't know if they improved on that front. In the past, their coin control feature involved having all UTXOs in your wallet selected by default and you would have to manually deselect those that you didn't want to use one click at a time. Imagine if you have a wallet with 50 or 100 different UTXOs. There was no button to deselect all automatically.

Personally, I 'd prefer to see a button "max", which, when pressed, would fill the amount with the maximum amount I have in my wallet. This way I would still be able to see the final amount, while also having the ease of using the "max" button so that I don't have to manually enter the amount.

Ideally, I want the wallet to have a checkbox on the left (or right) of each UTXO, so that I can choose which one(s) to spend from.
Then, the "max" button should:
(1) summarize the UTXOs that I have chosen to use, without messing with the other ones.
(2) subtract the fee from the amount, so that I can see what the final spend amount will be. This is very important, because when spending specific UTXOs, I need the fee to be spent from them and not mess with the other UTXOs I may have in my wallet.

I've already read somewhere (perhaps even in this topic) that it is not possible to make RBF if the wallet is imported - I'm just wondering if it's some kind of technical limitation that can't be bypassed, or is it something else?

I once found myself in a situation where I had exactly such a wallet and I didn't know that it was not possible to create an RBF (imported from Electrum), so I was surprised how it was possible that this option didn't exist.

I know that my response is not really related to your questions, but your post reminds me of an RBF related incident (using BlueWallet) a few days ago that I had, in which I was dealing with a merchant who accepts bitcoin.  

I was in their shop buying a couple of electronic goods that added up to around $2k in dollar value (maybe around right around 0.019 BTC (or 1.9 million satoshis), since the BTC price was around $106.5k at the time of the transaction), and at the same time, their wallet was an exchange, and at first they asked me if I used the same exchange as them, so that the transaction would be instant.  

I said that I did not use that particular exchange, and I did not really like the idea of using exchanges for transferring value, yet we were in a situation in which we were in a hurry and we also wanted the goods and we were traveling in that location, so it would not be very convenient for us to come back at a later date to finish the transaction or to pick up the items at a later time.  I said that I was using Bluewallet, and so I thought that there should not be any problem sending the transaction and getting the transaction to go through fairly quickly.

I quickly looked at Memepool.space and I saw that the last 20 blocks had lowest level transaction fees between 1 sat per vbyte and 3 sats per vbyte, and so Bluewallet was recommending right around 8 sats per vbyte for fastest, 4 sats per vbyte for medium and 1 sat per vbyte for slow, and so since I am so smart, I decided to use a custom fee of something like 3.67 sats per vbyte, and I was sure that the transaction would go through in the next block.

My friend who is still in the earlier stages of learning about bitcoin was with me and kept telling me to click on "fastest," and since I am so smart and so much more experienced, I said that there is no need to worry about the transaction going through, custom will work better and save some transaction fee money too... so I stuck with my 3.67-ish sats per vbyte, and so then we waited and we waited, and I kept looking at mempool.space, and about 15-20 minutes into the process, I saw that the next block was going to be 5 sats per vbytes, so I knew that the transaction was not going to go through in the next block, so quickly (and somewhat secretly) I went to my transaction in BlueWallet, and I went to the RBF section, and I bumped the transaction up to something like 10 sats per vbyte.  I again looked at mempool.space, and the next block had still not gone through, and so that block ended up taking close to 40 minutes before it went through and my transaction ended up going through and being in that next block, and lucky for us, the guy was willing to give us our products upon 1 confirmation, even though the transaction did not show up in his wallet, yet...

So then as we were driving away, we noticed that it took another 40 minutes before the transaction had 3 confirmations, but we were already quite far away from the shop, since the guy had released us with the products that we had bought with only 1 confirmation.  

All ended up going well with everything, since I have no clue about how to change a transaction that already has 1 confirmation, even if I were to want to be evil and to try to double spend that transaction or to try to cancel it or to try to send it back to myself. I was not really trying to sell at the top, but yeah, we had a dip since then, and so only currently are we getting back to the same price that i had sold.. to the extent that it matters.  I did not do spend and replace with those BTC (as I would have had done prior to 2021), since my BTC costs are likely around $20 for those same BTC that allowed me to transact at a value of around $2k.

Maybe it's different if you recover the wallet from seed than importing a private key. I found this reddit topic where a user had some issues with a different wallet from which he made a transaction with low fees. It took too long to confirm so he decided to bump the fee. He claims that he imported the seed into Blue Wallet and he was able to use RBF there.

There is also this thread from Bitcointalk: BlueWallet Default Transaction Fee Option
Check the replies by Eternad and Charles-Tim towards the end. They talk about private keys being the culprit why the RBF option is missing.

Thanks Charles,

I’m using the private key of my specific wallet that I created from Electrum then import to Bluewallet for a compatibility for my ios device. I’m sure that RBF is available when I’m using this wallet on my electrum wallet.

Is RBF feature removed if I use the private key of my specific wallet address instead of importing the seedphrase that containing multiple wallet address?

I think that is what that caused it, because you import private key. (irrespective of the wallet you generate it), instead of BIP39 seed phrase. This is also new to me, but that is just the reason. Electrum has not disappointed like this, but I have learned not to use more than BIP39 seed phrase on Bluewallet if I want to be able to use RBF to pump the fee. Likey also you will not be able to use CPFP also to pump the fee if you are the recipient.

Sometimes the time between blocks can be over 60 minutes, and it happened to me a couple of times when I needed confirmation as quickly as possible, but in that situation, unfortunately, nothing helps except waiting.

Regarding double-spend, if a BTC transaction has 1 confirmation, then it is not possible to do it - although for some larger amounts, it is recommended that the number of confirmations be at least 3, and for extra valuable ones at least 6. I think it's related to the 51% attack option where an attacker could reverse any transaction that doesn't have at least 6+ confirmations.


@Pmalek, I had a seed from Electrum that I imported into BW, and unless I completely overlooked the RBF option at that moment, then the same does not exist for the imported wallet. I remember that I tried all possible ways of bump fee, but I did not find that option anywhere.

Maybe the problem was in the BW app version considering it was 1+ year ago - I'll definitely test again.

Technically, it can be done if a chain reorganization happens. But that's not something that a regular user like you and me can affect. If a reorg happens, the confirmed transaction goes back to the mempool to wait to be confirmed. The sender could then doublespend it, paying a higher fee and hoping nodes will pick up the new transaction instead of the first one. I don't think Bitcoin has ever experienced a case where a confirmed transaction was successfully doublespent though.

There has been at least one case of successful double-spend.
In 2013, a forum user could do a double-spend successfully while the first transaction had been included into the blockchain.

Visit the following topic for more information.
A successful DOUBLE SPEND US$10000 against OKPAY this morning.

Interesting case. Wasn't one of those transactions dropped though and its block orphaned in the end? Two separate chains existed for a couple of hours and we had a fork. The double spent transaction was against OKPAY and affected them due to some peculiar circumstances that happened at that time.
