Anyhow, considering Your expert opinions, what is the way to solve this issue?

Are there any other communities or sources to inquire from?

Thank You.

Speaking of Blockchain.com Support..

I had been dealing with them for over 3 months by the end of September, our history contains almost 100 letters..

They started from inquiring my xPubs which I gave. I was advised to “Recover Funds”, to “Archive” and to “Unarchive”, to use Google Chrome, “Incognito” mode, to restore the App., etc., and after three months, having inquired the xPubs for the third time, they informed:

“Your current account xPubs couldn't have generated the BTC addresses in question. They are 100% associated with another account.”

I believe if it was the issue, they would have pointed this out to me at the first place..

No sense in three month “Support”!

 

“Add Next Address” button creates New Addresses under the Segwit Tab in Blockchain.com wallet, they are not the same as the “missing addresses” and they stay under the “Unused” Addresses since I am only creating them and not sending to be used.

The wallet does not “REcreate” the “missing addresses”.

 

I have created the 8 Electrum Wallets already, they are all being SYNC, the circle “Network” icon is GREEN.

Enabling Console “View – Show Console” going to Console Tab and using the “ismine..” returns with “false”, however, there is a chance I did not go through ALL of the possible Derivations..

 

The Legacy transactions are displayed in the Electrum Wallets with the seed from the Blockchain.com..

 

“I have seen issues in the past with blockchain.com reportedly generating addresses which are not covered by the user's seed phrase. You can try their support, but from previous experience they seem almost entirely useless. I think your best bet is going to be to use Ian Coleman or Electrum offline and just trawl through dozens of derivation paths until you hopefully find the right one.”

 What is "the addresses are not covered by the user’s seed phrase” and how to deal with this matter?

 
Support is useless as You predicted..


Please, distinguish the idea of using Ian Coleman or Electrum offline? What is the procedure or where to take the hints to solve the issue?

 

By Your opinion, is there any chance to find the Blockchain.com support PIC on the web to directly contact and to describe and solve the problem?

 

Is there any possibility to find support from somewhere else and pay for this issue to be checked, explained and solved on my behalf?

 

Thank You.

In the case i did the choosing BIP39, tried the "Detect Existing Accounts" option, after that Electrum Wallet detected BIP44 Legacy Account 0 providing the evidence for transactions made under Legacy Tab in the Blockchain Wallet, transactions' amounts and dates were correct, would it still be the issue "to sync the "blockchain headers" with the servers before it can display the correct balances" under the Segwit Tab?

"easier way to search addresses is to go to view menu > show addresses, switch to addresses tab, press ctrl+f and paste in the address in question." Thank You for the advise. Does it concern the Electrum Wallet?

"How do you know the addresses you are checking on a blockchain explorer?". I created them myself. I used the correct Blockchain.com Wallet because it is the only one. i sent the Addresses to the Sender, the only ones i created in the Wallet. There is no possibility i could send incorrect addresses because they were the only ones i created. I do not know about the malware issue, but the BTC balance is on the addresses i sent (blockchair.com, etc.,), the balance is "Unspent", amount is correct, and did not disappear anywhere else. i do not know whether it is the evidence or not.
If i go to "Add Next Address" under the Segwit Tab i can create the new address and it is shown under the "Unused Addresses".

I created the 7 of the Addresses because there was a limit for the amount to be transferred by the Sender, so, i did each Address for each amount simply choosing "Add Next Address".

"You can also try that to check if you can reproduce those addresses into your blockchain(dot)com's unused addresses list." Could You, please, send the hint for this to be managed?


Thank You.

i did the trawling through Derivation path as well..

i have tried everything You advised..

I got my seed phrase from www.Blcokchain.com.

I created the new Electrum Wallet as described, using the seed phrase from www.Blockchain.com and, choosing the BIP39, tried the "Detect Existing Accounts" option, after that Electrum Wallet detected BIP44 Legacy Account 0 providing the evidence for transactions made under Legacy Tab in the Blockchain Wallet, transactions' amounts and dates were correct.

But NO evidence for transactions made under Segwit Tab at all, no "Unused" and "Used" Addresses..

However, my Blockchain.com Wallet is the only Wallet i could create these Addresses in, i have created them (all seven of them) at the same time (within 20 minutes) and sent to the Sender. The next day i got evidence from the Sender the transactions' Addresses and HASHes.
As i understand, since the Sender used the Addresses i sent, the Addresses cease to exist under the "Unused" Addresses Tab in my Blcokchain.com Wallet but never appeared in the "Used" Addresses Tab along with no evidence of the BTC balance.

I could never possibly imagine or create the bc1 42-digit Addresses myself and there is no other Wallet i could create them in since i have the only one Wallet.

However, if i go to www.blockchair.com or elsewhere (Blockchain Explorer, Blockonomics, etc.,) i see the transaction history, it is "Received", "Confirmed" and "Unspent".
For example:

bc1qw7ppe93na289sp5jt3cm0w8zh9els2nld0tv7u

hash: 9f6db972726d76e387ca3e95645b3c0820c851f283b21f2cecefeffe67e489c3

This is evidence from the Sender.

What is another way to recover the BTC balance?

Thank You.

Thank You.

So, as i understand, should i import the seed phrase i created in the www.blockchain.com Wallet from the www.blockchain.com Wallet to newly created www.electrum.org Wallet?

Shouldn't the Electrum Wallet generate New Address to send to?

Are there any other options, steps or methods except Electrum Wallet to be created?

Thank You so much!

 

Thank You so much!

I have checked the HASHes and Addresses with the blockchair.com (as well as Blockchain Explorer, Blockonomics), balance is not zero, it shows the BTC balance i am expecting. Addresses i sent to the Sender have the BTC balance, transactions are Confirmed and balance is Unspent.

I understand i should recover the balance with Electrum or elsewhere but not familiar with the patterns and method.

Are there any steps to take or procedure to follow (any information to obtain)?

I have tried this: https://blog.blockonomics.co/how-to-restore-blockchain-com-wallet-into-electrum-f593ec79ab3d, but did not succeed.

Apparently, i am missing something.

Thank You.

Please, help to solve the issue:..

I created seven Segwit addresses (in June 2021, apparently, they were changing from Legacy to Segwit at that time) in the Blockchain.com Wallet, sent them to the Sender, transactions were made (they have status "Confirmed"), however, there is no balance in the Blockchain.com Wallet along with no evidence of Used and Unused Addresses.

Please, advise the way to recover funds and shift them from Blockchain.com Wallet to Electrum or elsewhere..

Thank You.
