Title: Just Hacked My Own Wallet (And Lived to Tell the Tale): Beginner's Guide to Debugging in C++

Hey fellow devs, just wanted to share a crazy story with you all. I was working on a personal project, a simple wallet for a new crypto coin, and managed to accidentally implement a vulnerability that would've let someone drain my entire balance. Luckily, I caught it before it was too late, and I'm here to walk you through the steps I took to fix it and the lessons I learned along the way.

"I've had my fair share of wallet mishaps, but luckily none of them resulted in losing my coins. What I found super useful was learning how to use Valgrind and GDB to step through my code and identify the issues. Thanks for the tip on using a debugger, OP!"
