The minimum fee rate for being eligible to use their free accelerator is 10 sat/byte. That would be around 16-19 sat/vbyte depending on number of native segwit inputs and outputs.

ViaBTC has around 11% of the total hash rate and it's estimated that they mine block 1 block in every ∼110 minutes on average.

Rebroadcasting a transaction is usually useless and note that you don't have to use a wallet that supports RBF for that. For rebroadcasting a transaction, all you need is the raw transaction.
If you have the raw transaction, there are many tools that can be used for rebroadcasting the transaction.

You probably meant vbyte, not byte.
It's possible to make a normal segwit transaction including 1 input and output and with the (virtual) size of around 109 vbyte.


To be eligible to use ViaBTC free accelerator, there's another requirement too and it's that the transaction must not have any unconfirmed output.

They do support withdrawal to taproot addresses.

You can click here to see one of the transactions made by binance for processing withdrawals recently.
If you check the receiving addresses of the transaction, you can find a taproot address among them.

Take note that there are no such things as bitcoin legacy network or bitcoin segwit network. We have only one bitcoin network and all bitcoin transaction are made there.
Legacy and segwit are the terms used for referring to different types of addresses and different script types.

The transaction sending 0.0023 (from your hardware wallet to your electrum wallet, as you say) has spent the fund received 2 months ago and has nothing to do with the transaction sending 0.05 BTC.
As I said in my previous post, the 0.05 BTC hasn't been moved from 3BwYFVunGWNScpeskEUHjAv7BesM9AEMEC at all.

Do you own 3BwYFVunGWNScpeskEUHjAv7BesM9AEMEC? If this address belongs to your hardware wallet, the fund is still there.

Are you sure this is the transaction you are talking about?
In the transaction in question 0.05 BTC was sent to 3BwYFVunGWNScpeskEUHjAv7BesM9AEMEC. Does this address belong to your hardware wallet?

In OP, you said that you sent back the fund to your electrum wallet. The fund (which is 0.05 BTC) hasn't been moved from that address and is still there.

This is exactly the error mentioned by nc50lc and means that the transaction is trying to spend the coins that don't exist in UTXO set.
Now, the only solution is that the sender makes a new transaction.


Take note that unless you completely trust the sender, you should never accept an unconfirmed transaction. There is no guarantee that an unconfirmed transaction will be finally confirmed.

If you are referring to the series of 12 words electrum gives you when creating a standard wallet, that's called seed phrase.
Passphrase is the combination of words or characters added to the seed phrase for extra security. Passphrase is also called custom extension word or 13th/25th word.

That's right. You should avoid any custodial service for holding your bitcoin.
In addition to the possibility of getting hacked, custodial services like exchanges can freeze your fund for any reason. You should use non-custodial wallet, so that you have full control over your fund.


Electrum is a trust worthy open-source wallet. The code has been reviewed by many people and no vulnerability has been reported.
But take note that any online device is prone to hacking. Even if you use a secure wallet like electrum, it's still possible that your device is infected with a malware and your wallet is hacked.

If you want to be completely secure, you should run electrum on an air-gapped device or go for a good hardware wallet.

If you are going to use electrum, keep multiple copies of your seed phrase in different locations and avoid keeping it on an online device.
Also take note that the seed phrase is all you need to recover your fund and anyone who has access to your seed phrase can steal all your fund.

The transaction OP is talking about is "Local" and the "Child pays for parent" option wouldn't be available in the right-click menu.

Assuming the transaction in question is still valid, first OP should broadcast the transaction or connect to a server that still has it in their mempool. After that, he/she would be able to do CPFP.
If the transaction is no longer valid, there's nothing that can be done except contact the sender and ask him/her to make a new transaction.

Local means that the transaction is in your wallet file, but the node you are connected to doesn't have it in its mempool.

What happened when you broadcasted the transaction? Did you get any error?
Unless the transaction is invalid now, it should be broadcasted to the network and its status should change to "unconfirmed".

Yes, Charles-Tim is right.

No.
Bitcoin blocks are mined at the rate of 1 per ∼ 10 minutes on average.
If the fee you pay for your transaction is high enough, your transaction can be included in the next block. Whether you use legacy address or segwit address, you can't get confirmation before the next block is mined.

Are you sure of that?
The minimum fee rate required so that your transaction can be relayed is 1 sat/vbyte and it's not possible to broadcast a transaction with lower fee rate.


Since OP's transaction includes 4 inputs and its size should be bigger than 500 bytes, it can't be submitted to ViaBTC free accelerator.

This has been already answered in previous posts.
Bitcoin blocks are mined at the rate of 1 per ∼ 10 minutes on average and there is no way to know the exact time the next block will be mined.
It's possible that the next block is mined in less than a minute and the miner includes your transaction if you have paid enough fee.

It's possible that a transaction is confirmed in less than 10 minutes. We don't know when the next block will be mined.

What do you mean by "difficulty is going up"?
The difficulty is adjusted every 2016 blocks. It was adjusted 2 days ago and the next adjustment will be around 12 days later.

Your calculations are wrong.
APY means Annual Percentage Yield and that's the interest rate you can get if you hold your fund for one year.
If you lock your FUN tokens for 90 days, the APY would be 15% and that means that you would get around 3.7% interest for the 90 days.

All those transactions were broadcasted to the network before your previous post and you were right. There was no more activity.
8 transactions were made from their multi-signature address today. 5 of them have been confirmed and 3 of them are still unconfirmed.

Someone claimed that the wallet which the transaction in question was made from had been hacked.

And here is the message signed from the same address posted by the same twitter account.

This is not true.
You sign message with your private key, not with your address.

Look at the following example.

Private key:
L3Gif2E2Zdgc4kC47jLzpNtWvBLuE8rpSPowmYqZM2mC8Mjs8otT

Legacy address:
1Q4U4dfZJgBRqXrHAnv8FSCqKxzjqRJ4ca

Segwit address:
bc1qlnetknv5vza7vjakc22dkq895cczf4pkpkmcmm

Here is the message I just singed with the above private key:


And here is the signature.



You can now use electrum and verify my message with both of above addresses.
If the tool you use doesn't allow signing message with a segwit address or it uses a different algorithm when signing/verifying message, the issue is related to the software.
