Current behaviour

Hello,

I need help explaining this problem: bitcoin core balance bitcoin core transactions

when I sent two transactions from my bitcoincore wallet, it created other transactions with different amounts in them and sent them to unknown addresses. But the bitcoincore wallet shows me the correct balance, but the public address of the wallet shows me a smaller amount. What is the problem or has the bitcoincore wallet created another public address of my wallet and everything is as it should be? TX transactions: https://mempool.space/tx/f5b121348993c768a898f93f8935c93df002565378b438fb87298de60bb51430 https://mempool.space/tx/464982c71089773479b8e1bd5af9f9d62c6f08d3873511b093f31b9c8607cf2a

I had bitcoin core version 22 when I submitted, now I have reinstalled it to version 25.1.0

Expected behaviour

I expected it to send only one transaction and the original wallet balance would be lower even with the sent transaction fee.

A transaction may have a change output, if the amounts of all input coins is larger than the transaction fee and the transaction recipient outputs.

@FacehuggerCZ In Bitcoin Core the outgoing amount of a transaction is the amount you entered to send + mining fee. So that’s why you see on an explorer that the address received 0.1, but the outgoing tx amount in Bitcoin core is 0.10061201. 0.1 plus the fee add up to the tx outgoing amount.

The second questions “What are these addresses”, those are the change addresses. It’s how Bitcoin works. That money is “back” in your wallet. But to a new unused address instead of the 1MomRR… address. that is by design.

Usually the issue tracker is used to track technical issues related to the Bitcoin Core code base. General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange or the #bitcoin IRC channel on Libera Chat, or any other place that you feel is well suited.

Thanks for the replies, I just wanted to make sure that I didn’t happen to have my bitcoin core hacked…
