I created 8 wallets to do a business with a DApp. After transferring the money for registartion 0.027 was taken out of 3 wallets. In some cases it was taken out before I did any registration and the transaction for all the wallets went to the same etherium code. Please advise if there are some service charges that the system does to wallets every now and then?
The wallet does not take anything.
Maybe someone has gained access to your wallets.
Never ever give out your recovery phrases.

To tell the truth, I never shared the wallet phrases with anyone. The money went out immediately I funded the wallets. Same thing happened to one of our team members. 0.03 was deducted from his wallet by the same code that deducted from my wallets.
Most likely this is due to some kind of smart contract that you have signed up to.
