I respect you, and applaud your efforts. Use testnet, if not regtest, if for nothing more than it being built into your development process. I can't think of a single reason to test on main, and respectfully, doing so expresses a precise development naivete.
I’m just an amateur “programmer” who has an idea and decided to try AI agents to make it real, if you go through my post history. One of many. Likely to fail. But I’ll admit I’ve just been lazy to do testnet, and I need to start using it.
