Topic: Trust wallet dust UTXO error (Read 430 times)

With every segwit input you add to your transaction, you increase the (virtual) size of your transaction by ~91 vbytes and with every legacy input to your transaction, you increaase the (virtual) size of your transaction by ~148 vbytes.
(Segwit addresses are the ones that starts with bc1 and legacy addresses are the ones that start with 1)

The purging fee rate for nodes that are using default setting is now around 5.3 sat/vbyte. This means that the minimum fee rate you can use for your transaction, so that it can be broadcasted to the network is now around 5.3 vbyte.
If you are in hurry and you want your transaction to be confirmed very fast, you should use the fee rate of around 10 sat/vbyte.
If you want your transaction to be confirmed in the next few hours, the fee rate of around 7 sat/vbyte should be enough.
(Note that the required fee rate may change over time.)

Let's say you want to make a transaction with the fee rate of 7 sat/vbyte and all your UTXOs are segwit. For every UTXO you add to your transaction, the transaction fee increases by 7*91 vbytes (637 vbytes).
If you have a UTXO worth 600 satoshi, you shouldn't spend that now, since the fee required to spend that would be higher than its value.
If you have a UTXO worth 6000 satoshi, you should spend around 10% of its value to spend it. It's up to you to decide whether you want to spend that now or you want to wait until the network is less congested and you can spend that with lower fees.

For choosing which UTXOs you want to spend, you should go to "Coins" tab on electrum and use "Coin control" feature.
Note: Coin control feature is available only on desktop version of electrum.

This is very helpful!
So, sending the max amount on Electrum from the imported trustwallet address to newly created Electrum address with default transaction fee would solve the UTXO dust problem? Or do I have to adjust the transaction fee and the amount? And yes, I agree that I should move away from trust wallet.

Yes, you will only be able to see Bitcoin balances and spend only Bitcoin. Electrum supports only Bitcoin.

Trust wallet doesn't offer a good solution to the UTXO dust problem, and it's even closed source. Avoid it. You will be able to sweep all the UTXO's with Electrum

Yes.

For your bitcoin wallet, know that Trustwallet is close source and it would be better to use Electrum to create another wallet and send all the coins from Trustwallet imported seed phrase on Electum to an address of the seed phrase you created on Electrum itself.

UTXOs should not be disregarded, but it is Trustwallet that is disregarding the dust UTXOs. You can send dust amount on Electrum wallet in combination as long as they 546 for legacy address or 294 for segwit or more (transaction fee not included yet).

Hi everyone!
I do have a similar problem, where I cannot make any transaction out of trust wallet, probably due to utxo dust. I am thinking to do a similar thing as suggested in this thread, import my address to Electrum using the seed phrase. I have a couple of questions:
1) Is it correct that only BTC will be imported? The other coins can still be used in the trust wallet?
2) How does making a transaction in Electrum with imported BTC address with UTXO dust solve the problem? Does Electrum automatically disregard the utxo? My transaction will be pretty large.

Thank you for any input.

It seems you were quite impatient to see those transactions get confirmed. I don't see why because you sent the coins to yourself. There wasn't a trading partner on the other side waiting for his money or anything. In those cases, it really doesn't matter if the first confirmation is in 2 hours or 10 days.

If you had just left those parent and child transactions alone, they would have gone through by now by themselves. There is less than 0.4 vMB of transactions paying 25 sat/vByte right now, which is your effective fee rate. That means, everyone paying that amount will have their transactions confirmed in the next 1-2 blocks unless we don't see a sudden spike in new transactions or long waiting times between blocks. Sometimes it's just about being patient and not being in a hurry.   

Sure but the estimated time for the parent transaction was set to 24 hours for two days. The thing is i couldn't double spend because no BTC funds were in that wallet left after the transaction which i eventually canceled. By double spending i mean bumping the fee. This option didn't turn white on electrum. So i canceled the transaction, fees were deducted and made a new one. I know that you don't have to wait but just to be sure I waited which was only minutes.

Made the new transaction and you are right i effectively paid around 28 USD in fees for a final transaction of around 30 USD lmao. However i don't care about (this) money. I learned something which is good. Ohh well plebs like me being plebs. I'm learning slowly. I think all this time i paid too many fees for some transaction i didn't inmidiatly needed. Next time I'll make sure to pay the minimum required fees (for the time i want it to be processed in depending on the nature of the transaction). No double spending or cancelation of TX is needed. Btw I realise that's about the same thing right?

You didn't have to wait for 6 confirmations. You could make your new transaction even when those transactions were still unconfirmed.

Note that with canceling a transaction and then making a new one, you have to pay fee for two transactions and you waste some money.
Instead of canceling the first transaction and then making a new one, you could bump the fee. With bumping the fee, you replace your transaction with a new one spending more fee.

Thanks again all. Actually i managed to do it finally within minutes. I canceled the small transaction. With that the parent transaction which was pending for too long. After cancellation those transactions were replaced by fees. Don't know how else to put it i am probably saying it wrong.

But when the child and parent transaction were cancelled they both inmideatly jumped to one confirmation. I waited for 6 confirmations for the fees deducted. Then i made a new transaction and it arrived within 10 minutes. Simple. Hard to explain tho since I'm a pleb lol. I really appreciate all the help. Active forum with deep technical understanding of bitcoin.. pretty rare. Btw isn't this like the perfect time for miners in a long while?

Well that's true. However i can control it fine when it's just sitting in my ledger. Well that's actually wrong it's not fysically in my ledger but you get the point. Can control it as long as I don't mess with it lmao.

Sorry for the inconveniences, it can be hard to understand at first, but it becomes easier later on. Neither Electrum or even BTC is fool-proof, there is always a chance for users to make a mistake, neither do i think there is any system that is fool-proof. But once you understand how it works, you can use it easily without any mistakes.
Electrum allows you to adjust the fee rate based on how quickly you want miners to confirm your transaction, not everyone wants to pay a high fee as they are willing to wait, while some people do not have the time to wait and will use enough fees so their transaction can be confirmed fast, that is why you should check the mempool before making a transaction, so you know the best fee rate to choose personally.
CPFP is a good feature for bitcoiners, even though it can be expensive based on the size of the TX's. Imagine your transaction is stuck and there is no way to bump its fees, that is why there is rbf and cpfp to enable people bump fees and get their transactions confirmed quicker.
Controlling your own money has never been simple .

The total fee doesn't matter on the Bitcoin protocol. What matters is how much you pay per v/Byte. We pay a certain amount of sats per vByte. Imagine a courier who carries packages to customers. Now imagine you have the freedom to decide how much you want to pay him per 100 gram of weight you ship with their company. And they only care about that system of payment, not the total you'll pay for all your packages. Now, I am willing to offer $1 per 100 gram, while your offer is only $0.20/100 gram. The courier will favor all customers paying the highest amounts per gram as there is limited space in his truck. Maybe it's a bit clearer now, maybe not. 

Your new transaction is broadcasted with much higher fees than your first one. 93 sat/vByte vs 20 sat/vByte if I remembered correctly. The number you should be looking at is 25 sat/vByte as the effective rate for both. With the way things stand now, you are about 5-6 blocks away from a confirmation. Obviously, that's just theory because new transactions are coming in and some will pay more, others less than what you did. Just wait it out. Maybe the mempool clears a bit during the weekend. It usually does, but last week was different.   

Thank you for the help but my brain is already dead. I'm done. I canceled sister payment and now balance is 0. I hate electrum now and trust wallet. Why in gods name can they not make a transaction fool proof?? Why allow to send with less fee and 20 inputs? Why. I don't get it at all. Fuck this bitcoin. Why electrum let's you make a payment when the parent one isn't yet confirmed and also the newer one with less fees. Didn't even get a warning only that i pay unusual high fees. Fucking bitcoin man i thought you were a simple coin. Lmao I'm gonna sleep under my rock again like Patrick.

Take note that what matters to miners is the fee rate, not the absolute fee.
The fee paid for the parent is higher than the fee paid for the child, but its fee rate is lower. The fee rate used for the parent is 20.1 sat/vbyte and the fee rate used for the child is 93.3 sat/vbyte.


The parent isn't a small transaction. It includes 20 inputs and has the virtual size of around 1400 vbyte.

Sure but i paid fees total of 30k sats and according to mempool it's not going to be processed anytime soon. Maybe thats because the parent transaction has much higher fees than the new transaction. I think this transaction will get purged too after two weeks. It's not broadcaster and signed hence i could and probably still can cancel the tx. I think the fees i paid for this small transaction is more than enough. But protocols are protocols. Good luck to the people willing to pay 20 USD fees for small transactions in order to get it confirmed. I understand the miners tho. You have to stay profitable.

The interface of the desktop version is of secondary importance because the wallet works just fine. The mobile version of Electrum is another can of worms, though. Its looks are outdated ,and it just feel buggy and incomplete. I have never felt comfortable using it.   

In theory, yes, but in practice it's a bit different. Other members already introduced you to the term 'purging'. You can see the data for purging in Mempool.space. The memory pools don't have unlimited capacities. When they run at full capacity, the software removes/deletes/purges transactions that pay the lowest fees to make room for those willing to pay more. If you broadcasted a 2 sat/vByte transaction right now, chances are that mempools would reject making a record of it. It just doesn't pay even nearly as much as it's needed for an onchain confirmation anytime soon. 

Very technical but after a look at the mempool again i dont believe it is going to be confirmed today or tomorrow or even a week from now. Because that first transaction will never be confirmed lol. It's stuck at 24 hours estimated time since yesterday and not moving. I'm going to write this little piece off as a lost and remove the imported electrum wallet. Dont trust this wallet anymore (officially trust since it's an import seed from that). Just going to resume on new electrum wallets. Not going to make this mistake again.

The effective fee rate is equal to the total fee paid for two transactions divided by their total size and that's what matters to miners.

You paid 28040 satoshi for the first transaction and 10,290 satoshi for the second transaction. The (virtual) sizes of the transactions were 1400 vbyte and 110 vbyte, respectively.
This means that you paid 38330 satoshi for 1510 vbyte. It gives you the effective fee rate of 25.4 sat/vbyte.

Note that the transactions will be confirmed at the same time.

Thank you i finally understand that bit. It's basically the same transaction. I canceled the tx from my earlier transaction and the funds where send to my own balance again on electrum. Then i made a second transaction which I'm waiting for now. So by cancelling my first transaction I have to wait for those funds that returned to my wallet (to confirm) before i made the second transaction to confirm. Electrum let me make transaction anyway. That's why it's stuck on 30 min on mempool forever (estimated time for confirmation).

This is your address: bc1qddytrwznva7c2rmkn87s5tlx938gv0parg3gkq

You will see that you make a transaction. But you will see that you spend from an unconfirmed transaction. Some wallets like Electrum can spend from unconfirmed transaction.

Because the unconfirmed transaction that you spend from has not been confirmed is the reason. The fee you used in the later transaction is not still enough to get the unconfirmed (parent) transaction and your transaction confirmed early. Just wait as the mempool is becoming less congested.

Man i really don't understand that sorry. By parent consolidating you mean the transaction that i canceled right? Because it's almost the same in amount. How can they both be confirmed? That would mean i get the funds two times? There is only about 45 USD in that wallet. I'm thinking all those inputs are from the failed transactions earlier? In other words the parent transaction has been cancelled but still needs to be confirmed? I'm not gonna up the fees. Don't care about this transaction but want to learn the technical procedure when something like this happens in order to avoid it in the future, altho i think using electrum instead of trust from now on will do the job. 20 inputs..

Your transaction has a parent consolidating transaction which has not been confirmed:

https://blockchair.com/bitcoin/transaction/91d240b52148b3d327c8910f93c4e9a582bacbea2a6dfcba22d4872981938ca4

The parent transaction has 20 inputs, which is high.

The fee you used for the later (child) transaction is not enough for both parent and child transactions to be confirmed. I will advice you not to pump the fee because the mempool is getting less congested. My advice for you is to just wait.

Thank you guys for all the extra info. Trying to learn a bit. Regarding my transaction it has been more than 25 hours lol.  Can anyone explain to me why mempool has two sections for the fees? Fees paid: 93.3 sats. Effective fees: 25.4 sats. Actual fees 10k sats, so three. My IQ is just as rekt as my transaction and obviously English is not my native language so sorry for that.

That's correct. According to mempool.space, at the moment of writing, transactions paying less than 3.90 sats per vByte are being purged. Most nodes will reject transactions paying less than that.
The good thing is that the number of unconfirmed transactions has decreased significantly in the last few days (from almost ~400k unconfirmed transactions to ~290k). So, hopefully in the next few days, we will be able to send transactions with only 1sat/vB, again.

It may worth mentioning that, currently you may not be able to broadcast a transaction with the fee rate of 1 sat/vbyte.
The minimum fee rate that is accepted by a node would be higher than 1 sat/vbyte if the network is congested and mempool size of the node reaches its maximum.

Just a small correction. You can't cancel a transaction once it has been confirmed, you can cancel it while it's still unconfirmed (after signing and broadcasting it).
When you click on "Cancel", Electrum will create a new transaction which sends all the inputs of the previous one to one of your Addresses. It's the same as "bump fees" but in this case you replace recipient address with one of yours.

The lowest fee that you can use is 1 sat/vbyte, that should be around 111 sat in fee. It depends on the mempool, if mempool is not congested at all, it will be confirmed. But mempool is congested and fee below 40 to 50 sat/vbyte may not get confirmed by this time. But the mempool congestion has reduced than before. But expect increase in fee at anytime.

Actually i have several trust wallets (and i can send larger amounts without any problems (ridiculous fees though even for higher amounts). Getting new electrum wallets with different seeds to empty those. Nog going to import them tho but just emptying them by a transaction from trust to new electrum wallets.

 I never keep funds long on wallets anyway. For that i use a ledger. I guess trust wallet is way more efficient using bch. But honestly this whole experience with trust wallet is just sad especially when it comes to the support. I'm guessing this whole spike in mempool is because of the new shitcoins on btc? So people willing to pay extremely high fees for small transactions? Ohh and trust wallet still has issues with the swaps even on the other wallets. So they have a rating of 4.7 in the playstore and electrum a 3.7? Lol.

I have used electrum a long time ago (on desktop) and it always did what it was supposed to do however the interface was like something from 1998 and i remember some problems but none of my transactions were ever stuck or whatever (yes sometimes it did take a while but not this long). I don't even know if it's possible for a btc transaction to get stuck even when you send it with like 2 sats fees it should in theory eventually arrive correct?

Good people here trying to help. I thank you all. Haven't used electrum since my desktop experience back in the day but the mobile app seems really good. I can learn a lot from this forum. Going to be a silent member untill I'm somewhat less of a pleb. 

He is doing a CPFP, but according to mempool space, his effective fee rate is 25.4 sat/vByte and not 93.3 at/vByte. Transactions in the 90 sat area are getting into the next block right now, and as you can see, OP's is still unconfirmed. The 25 sat zone is still about 14 vMB away. Things are looking a bit better though.

i saw your tx id and it seems you already doing CFPP to increase the transaction fees from the previous unconfirmed transaction by increasing it to 93.3 sat/vB.
so I believe your transaction will get confirmed in a day.

Glad that your problem has been resolved, and sorry Trust Wallet makes things look easy for beginners, but as soon as any problems occur, the headaches are violent.

Seed associated with that wallet contain serval cryptos other than Bitcoin, so if you have a balance other than Bitcoin, it may be best to check  before you decide to new wallet. It is also better to use a newly generated wallet in the future instead of the seeds that you got from the Electrum wallet.

Canceling a transaction means replacing an unconfirmed transaction with a new one paying more fee to your own address.
Note that you can replace an unconfirmed transaction with a new one paying more fee, only if it has been flagged as RBF.

What mistake did you think you made? You cannot cancel a BTC transaction once it has been signed and broadcasted, but you can "cancel" it through double spending if rbf is enabled, and that is what you did, you just created a new transaction with the same input to the address you want to send the funds to, usually should be done with a higher fee.
Your transaction would be confirmed, you just have to wait; there is no problem with it. Glad to hear you will be using Electrum wallet forthwith.

I already deleted this trust wallet. I think I made a mistake with my last transaction tho. After a while i still had the option to cancel it so i did and the fees were deducted anyway which i understand but usually you can't cancel a bitcoin transaction? I know about double spending but that isn't the case here. I made a new transaction which i can still cancel. (Just to empty this trust wallet balance). I suppose it won't go through although block explorer says it's all good. New transaction:
https://www.blockchain.com/explorer/transactions/btc/328d3229123b9b41840ee5c2d5d868b2a9f2d57ac2f92e56a06ebab83e2a08a6

This is still a transaction made from electrum using the twt seed in order to empty the wallet. Funds are still funds.
Will never use trust wallet after this and make several new electrum wallets. Hoping i get this sorted out first tho.

Good to hear that your issue is solved, but one more thing i would advice you to do is to ditch Trust wallet completely for Electrum, TW is closed source, but Electrum is an open source wallet that is recommended by most of the community. If you decide to do the right thing and start using Electrum, do not use it with a seed phrase imported from TW, like i said it is closed source and we don't know how the keys were generated, you should create a new Electrum wallet with a new seed phrase. Cheers.

Glad to hear that you sorted it out but did you manage to send the whole thing, or you had to lower it a bit?

I tried this and it says insufficient funds (0). I don't know how to upload a screenshot here. Very oldschool interface with good reason I suppose. I'm just a pleb.

And just now, like magic i tried the exact same thing again and it worked. Earlier it also turned to white but when i proceeded it said insufficient funds. Now it's all good. Thank you man. Really helped me.

That is how it is on Electrum version 4.4.0, 4.4.1 and 4.4.2. It will not show anything, just proceed to make the transaction. After you click on max, you will see the 'pay' icon at the lower right corner changed to white from no color and becomes clickable. Click on the pay icon to continue.

So i imported the seeds. It shows all transactions and balance. When i try to send anything and click on max nothing happens. As in i have no funds while there is 1.93 mbtc that should be available.

Damn that was stupid of me lol. Thanks a lot i could import it finally!

In the mobile wallet, on the page where you type your seed, there's a ComboBox to the right of "Seed type". It's set to 'Electrum' by default, tap it and change it to BIP39 and see if it works.

Thank you for your reply. It doesn't matter how much i lower the amount i still get the same error. The same goes with adjusting the fees higher or lower. Same problem.

I don't see the BIP39 option on the mobile app.
I have the option to create new wallets on electrum or import only read only modus. When i try to import the 12 frase seed it doesn't let me go to the next step in order to import the wallet.

Electrum should recognize the wallet if you select -> Options -> BIP39 after typing the seed phrase.

Trustwallet is slowly becoming unusable. I've been having that problem a lot lately, and the only thing I managed to do was to lower the amount when I was sending. It's probably related to the fees due to the number of transactions you might have received in the past (I'm guessing you haven't received the 31K in two or three transactions).

Hello all,

I have send 45 euro to my trust wallet yesterday.
I have made over 31000 euro in transactions on this wallet only. Trust support is like talking to a wall only even worse.

I am trying to send an amount to another wallet. It doesn't work. I always get the same error no matter how high i set the fees. The amount i am trying to send is not smaller than the fees. I can't even send 20 euro while paying 600 sats for fees. Getting sick of this. Trying to swap btc for any other coin and that is also not possible. Nothing is available. I have tried uninstalling and reinstalling the app on Android and still the same. Anyone else with the same issues? Can't import my wallet to electrum because it doesn't recognize the 12 seed words.
