So if I put MY wallet in the second cell, and the receiver's wallet in the third cell, I can actually send money with a 30 days delay, or cancel any time by paying a 1% fee.
I think you got it wrong FOCA

First of all you don't put any wallets anywhere, you just enter addresses. Second of all when you pay the 1% fee the money is released to the receiver.
Actually I'm being creatively exploitative with the way your site works to perform cheaper transfers and recover my money back if I want to
You should look into it.
