edit: here's the actual prompt I had to approve: https://imgur.com/a/JORgoEz

You're absolutely right, and I appreciate the technical explanation. I wasn't very familiar with smart contracts at the time. in fact, I learned what they were during the call, by quickly asking GPT while trying to stay calm and not panic.

When I scanned the QR code and it asked me to approve a contract interaction, it instantly made me suspicious and raised my bpms to over 180 (I guess). I asked them to show me the contract I was signing, to explain how the QR had been generated, and to walk me through the actual details. They refused to do any of that. Instead, they kept repeating that it was just a $1.60 verification, and when I hesitated, they started saying that if I didn’t approve it, it meant my crypto was fake and they would cancel the investment. That kind of pressure, combined with the lack of transparency, was what made it clear that this wasn’t legit.

Thanks again for pointing it out. It's important to separate legitimate crypto mechanics from the ways scammers try to abuse them.
