Bech32 question

Hi all,

I faced some weird thing after sending 0.001 btc from Bitcoin core. I sent it to this address:

bc1q8z68gxl2rl9dy8yh6ve4ugl4q7nl5lurcl53cy

But when I check this transaction in blockchain I see one more address:

bc1q4kpyjxmqr7uzcd5w62hc7t273u009tgkjps98p

I do not recognize it and I see that 0.01037810 BTC were sent to it from my wallet.

Is it normal or is it a problem? I sent it with replace-by-fee switched on, could this influence?

Please help me as I do not know what to do now, Bitcoin core shows only one transaction to the correct address and correct 0.001 sum.

Thank you very much in advance!

It is probably your change address.

Since Bitcoin UTXOs are spent completely, the remainder after the recipient amount is assumed to be used as fees. As a result, the wallet has to send the funds or the change to the new address within your wallet. As long as the amount from your transaction is -(0.001 + fees) then you are fine. The change addresses are not shown in Core (IIRC) to avoid confusing the users.

Thanks a lot!

I tried to find this address in my Bitcoin core both sending and receiving address but failed. Is it normal? Should I stop worrying and just continue using my Bitcoin core wallet?

It is not shown in the UI to prevent confusion.

Go to Window>Console and type in these (omit the first if it is not encrypted with a password):

walletpassphrase ....

Code:

listaddressgroupings

You should see your change address along with the receiving address.

*Clarified below: Makes sense since addresses are visible without any decryption.

walletpassphrase PASSWORD 600

Don't do this, it's not needed to use this:

You had 0.01140000  in your 1F8rErCh25PHkPeafBK3eaxpjoVktBdjS3 address in your wallet
You sent 0.001 to bc1q8z68gxl2rl9dy8yh6ve4ugl4q7nl5lurcl53cy

you have 0.0104 btc left out of which 0.00002190 has been used as fees for the tx.

The remainder amount of 0.0103781 has been sent to your change address bc1q4kpyjxmqr7uzcd5w62hc7t273u009tgkjps98p

If you go to bitcoin core,  and if you go to settings/wallet and  have coin control switched on, go to send bitcoins, on top there you will have an option called inputs. click on it, you will see the address 1F8rErCh25PHkPeafBK3eaxpjoVktBdjS3  with balance 0.0103781  displayed and if you click on it, below another line will open with address bc1q4kpyjxmqr7uzcd5w62hc7t273u009tgkjps98p and change written there with btc amount shown as 0.0103781 .

Next time when you send btc it will be sent from this address.  bc1q4kpyjxmqr7uzcd5w62hc7t273u009tgkjps98p

Nothing to worry about at all.
