Hello, you see I added balance to my app so users can top up and use that balance to make orders, but I'm afraid that it would be easy to crack and change the values of how much balance they have.
You see I went offline in my app and changed a value, and when I connected to the internet again that specific value got synced with the firebase collection so I realized that hackers can simply change a value in the app and it would be written as such in the firebase collection (offline or online) and would grant the hacker infinite money pretty much lol? am I overthinking this or is there a more secure way to go about this?
PS: I'm using stripe to process payments.
