What is blind signing? Why shouldn’t you sign if you can’t understand what you’re signing? Don’t panic—the class rep is here to explain:
Many hardware wallets don’t allow blind signing by default. If you encounter a contract call that your device can’t interpret, you’ll need to turn on blind signing in the settings.
Blind signing is like handing over the entire verification process to the website that initiated the request. If the website is a fake, you won’t be able to tell when confirming the transaction.
Knowledge may seem boring in everyday life, but you realize its value when you get burned.

Just my personal take—listen if you like, but it’s not advice.
