The transaction made with fee rate of 30 sat/vbyte will be likely confirmed in the next block. (A new block is mined every 10 minutes on average)
Transactions 1 and 2 no longer exist.

If you are in hurry, bump the fee of transaction 2.
If you are not in hurry, just wait.

As calculated, the total virtual size of your transactions is 427 vbyte.
Given that for a fast confirmation, transaction fee of around 14 sat/vbyte is required, you need to pay 5978 satoshi in total.
You have paid 3024 satoshi for transactions 1 and 3 and need to pay 2954 satoshi for transaction 2.
If you are in hurry, bump the fee rate of transaction 2 to 21 sat/vbyte.

You can pay a bit more (around 25 sat/vbyte) to make sure your transaction will be confirmed soon. The fee rate required for a fast confirmation changes over time.


With doing so, you invalidate transactions 1 and 2.
If you want all three transactions to included in the blockchain and you are in hurry, bump the fee of transaction 2.

Note that in my previous post, I had assumed that the order is transaction 1 ---> transaction  2 ---> transaction 3 and that was why I said you should bump fee of transaction 3.
Since the order is transaction 3 ---> transaction 1 ---> transaction 2, you should bump fee of transaction 2.

Again, no need to do anything, if you are not in hurry.

As mentioned by ranochigo, you have made the transaction 1 before transaction 2.
If you want these transaction to be confirmed fast, you should bump the fee of transaction 2

Note that with bumping the fee of transaction 3, you invalidate transactions 1 and 2 and with bumping the fee of transaction 1, you invalidate transaction 2.

When electrum says that a transaction has unconfirmed parent, it means that the fund which is being tried to send in that transaction has been received in a transaction which is still unconfirmed.

Assume that you have sent bitcoin from address A to address B and then the same coin from address B to address C.
As long as the transaction made from address A to address B is unconfirmed, the transaction made from address B to address C can't be confirmed.

The two transactions that have been marked as "unconfirmed parent" can't be confirmed before confirmation of their parent.

Can you share your transactions IDs?
With sharing your transactions, you may hurt your privacy. But it won't have anything with your security.

Assume that you have sent bitcoin from address A to address B and then sent the same coin from address B to address C.
If you bump the fee of the transaction made from address A to address B, the transaction made from address B to address C becomes invalid.


The total virtual size of your transactions is 427 vbyte and the total fee paid for three transactions is 3953 satoshi.
This means that the effective fee rate is around 9 sat/vbyte.
Your transactions are now around 45 vMB from the the tip and you shouldn't expect them to be confirmed soon.

If you are in hurry, bump the fee of transaction 3.
Currently, for a fast confirmation, the fee of around 20 sat/vbyte is required.
Given the total size of your transactions are  427 vbytes, you should pay 8540 satoshi in total.
You have paid 2945 satoshi for the first two transactions and you need to pay 5595 satoshi for the third transaction. So, you need to bump its fee to 38 sat/vbtye.

Again, if you are not in hurry, just wait.

Edit:
I assumed that transaction 3 is spending the fund received in transaction 2 and transaction 2 is spending the fund received in transaction 1.

This is probably the problem. Wasabi wallet only generates native segwit addresses.
If OP has created a wallet with different address format in green wallet, it can't be recovered in Wasabi.


You can use electrum. It allows you to import a BIP39 seed phrase with a passphrase.

Yes. Miners prioritize transactions based on the fee paid for them.

OP has paid 14 sat/vbyte for the transaction in question. It's now about 4.5 vMB from the tip and it shouldn't take a long time to be confirmed.

That's how bitcoin transactions work.  
Every time you receive a transaction, you receive a UTXO.
Let's say you have received two transactions. In each of them you received 0.5 BTC. Now you have two UTXOs and you want to spend 0.75 BTC.
As you UTXOs must be spent completely, you have to use both UTXOs. So you make a transaction with two inputs and two outputs.
One of receiving addresses is owned by the recipient and the other on is your own address which receives the remaining balance of UTXOs.


The network is so congested now.
If you are not in hurry, just wait. Your transaction will be confirmed.
If you are in hurry, you can bump the fee.

You can.


You don't have to create a new address.
You can give the same address to everyone you want.


No.
You can use the same address numerous times.


Using a new address is optional and you don't have to that.
Note that with using a same address multiple times, you may hurt your privacy.
The person who knows your address can track your previous transactions and know your bitcoin balance.

Using a change address is also for your privacy. In the case your sending address is used as your change address, everyone can know that which of the outputs is owned by the recipient and which one is your own address.

Anyways, if you want the remaining amount of your coins is sent back to the sending address, go to "Settings" and then to "Wallet" tab. Check "Enable coin control features". Check "Custom change address" when making a transaction and enter the address you are sending bitcoin from.

If someone has really sent you bitcoin, the transaction is final and there is no need to pay any transaction fee. So, he/she hasn't sent you any bitcoin.
Also, a normal bitcoin transaction doesn't need that high transaction fee.

Can you be more specific please? I guess someone is trying to scam you.
Anyone asking you to send bitcoin to receive more is a scammer.

In your previous post, you said that you made a transaction to an exchange and now you say you can't import your private key into electrum.
Am I missing something here?

If you are not in hurry, just wait. There is no need to waste more money on transaction fee.
If you are in hurry, right click on your transaction and select "Increase fee". Currently, you need to pay around 15 sat/vbyte if you want your transaction to be confirmed in the next block. (A new block is mined every 10 minutes on average.)
Note that the fee rate required for a fast confirmation depends on network state and changes over time.

No.
If you enter that mnemonic into a wallet, you can't get your vanity address. It will generate completely different addresses. Of course, it's possible to derive your private key from that mnemonic. But there is no wallet doing that.
Note that you can't derive your seed phrase from your private keys at all.

Anyways, Below is how pooya87 converted the WIF private key to a mnemonic.

WIF private key:


First we convert the WIF private key to a hex string using Base58Check encoding.

Now we remove the 80 from the beginning and the suffix "01" and the checksum from the end. The checksum is the last 4 bytes (the last 8 characters in the hexadecimal format)
Note that there is no suffix to be removed if you started with an uncompressed private key (a private key starting with 5).

Now we have a number in hexadecimal format.

The 256 bit number in binary format:


We should extend the 256 bit number with 8 more bits which is called checksum.
To calculate the checksum, we hash our number (as a hex input) using SHA256 function and then convert the result to a binary number. The first 8 bits is our checksum.
Checksum: 01101011

With adding these 8 bits to our 256 bit number, we have a 264 bit number which is shown below.


For converting this number to a mnemonic, we use BIP39 wordlist.

Each of 11 bits gives us a word.

The first 11 bits: 10111100101 ----------->1509 ---------> Word number 1510 in the list ---------> royal
The second 11 bits: 00011001001 ---------> 201 ---------> Word number 202 in the list ----------> bomb
........
........
........
The last 11 bits: 00101101011 ---------> 363 ---------> Word number 364 in the list ----------> coin


Again, there is no wallet deriving your vanity address from your mnemonic if it has been generated  using this method and you need technical knowledge for generating your address using that mnemonic.
Avoid this method, if you don't know what you are doing.

ViaBTC doesn't accelerate transactions paying fee of less than 10 sat/byte freely and that's why you couldn't submit that transaction.
To accelerate such transactions, you have to use their paid service.

I think you didn't get pooya87. He didn't say you can't have a seed phrase on a steel sheet or keeping a private key is easier than keeping a seed phrase. It's surely possible to have a vanity address generated from a seed phrase. pooya87 was referring to complexity of deriving a vanity address from a seed phrase.

If you want to have a vanity address generated from a private key, you generate a private key and then derive the public key and the address. You repeat the process until you generate the address you are looking for.
For generating a vanity address derived from a seed phrase, you add extra steps. You should generate a seed phrase and then derive the seed, the extended private key, the private keys, public keys and addresses.

Note that f_B is the fee rate you should use for the new transaction. It's not the absolute fee.
The fee required to be paid for the new transaction is f*(S_A+S_B) - S_A*f_A.
In your new transaction, you should set the the fee rate to (f*(S_A+S_B) - S_A*f_A) / S_B, so the absolute fee paid for it is f*(S_A+S_B) - S_A*f_A.

Let's say the fee required to be paid for the new transaction is 1000 satoshi and its size is 200 vbyte. I should set the fee rate to 1000/200 = 5 sat/vbyte.

The transaction was confirmed normally and without help of CPFP.
The output of the transaction in question was spent in another transaction with transaction fee of only 1.127 sat/vbyte which is even lower than the transaction fee of the first transaction.

The two new transactions have been made with lower fees.
The first transaction had been made with the fee rate of 2.7 sat/vbyte. You made the new transactions with the fee rate of 1.13 sat/byte.

Anyways, even if you had made the two new transactions with 1 BTC/vbyte, it wouldn't help your receiving transaction to be confirmed.
You made the two new transactions from the receiving address of the unconfirmed transaction, but you spent different UTXOs. For implementing CPFP, you must spend the UTXO received in the unconfirmed transaction.
The other mistake you did is that you spent significant number of other UTXOs is the same transaction. With doing so, you increase the transaction size and make the CPFP more expensive.

No. Your raw transaction doesn't include your private key. Instead, it includes a digital signature which can be used only for that transaction and becomes invalid if transaction data is changed.
By the way, why doesn't your friend let you broadcast the transaction yourself?

I knew you know that.
I made that post for OP or anyone else who want to do such a calculation.


You are right. For a newbie, it may be difficult to know what are fee rate and transaction size.

The screesnshot posted by Peanutswar has been taken from mempool.space.
It's a block explorer and can be used for tracking transactions.

You didn't tell us whether you have control over any of receiving addresses or not.
If so, as suggested by NeuroticFish, you can use CPFP method.
