If you look at the wallet commands using 'help' you will see that our wallet has a miner built into it 'start_mining'. Source code is open source and you are free to recompile the wallet and daemon for yourself.
It makes no sense to compile the wallet yourself, if I can not read and understand the code (and I can not, unfortunately).
Just wanted to say that it would be better if there were nothing suspicious in the wallet, it would positively affect the trust of users (I think you have an interesting project).
In any case, I install the wallet on a separate hard drive, disconnecting all other drivers.
