Yesterday i've tried to transfer the minimum amount of btc [ 0.00001 BTC ] from my bitcoin core wallet to the electrum one. The problem is that only 0.00000504 BTC were sent to the electrum wallet and !!!0.00109000 BTC!!! were sent to some random address.
I am curious why this happened.
ps: The blockchain explorer says it is all in one transaction, but sent to two different addresses.
