Kairo Guard - Know what you're signing before it's too late

by•
Most crypto losses don't happen because of bad luck. They happen because someone signed something without understanding what it actually did. Guard is a free tool, paste any transaction, smart contract, or suspicious message and we tell you exactly what will happen before you confirm. No wallet connection. No registration. Nothing stored. Just clarity before you sign. If Guard saves you from something, you can buy us a coffee in USDT. That's it.

Hey Product Hunt 👋 I built Guard after watching too many people lose funds to transactions they didn't understand. The "approve() unlimited access" type. The kind that looks harmless until it isn't. Paste what you're about to sign - we tell you exactly what will happen before you confirm. No wallet needed. No registration. Nothing stored. Free forever. If it saves you from something, you can buy us a coffee in USDT. That's the whole business model. Brutal feedback welcome. what would make this more useful for you?

Hi Product Hunt! 👋

I built this because I was completely lost when I started using crypto. New tokens launching on Binance, everyone moving fast, and me not really understanding what I was signing.

At some point I realized that one wrong signature and everything is gone. No warning, no undo button, nothing. And nobody explains that to you when you're starting out.

So I built the tool I needed back then. You paste what you're about to sign and Guard tells you in plain language what it actually does before you confirm anything.

No wallet connection. No registration. Just paste and know.

If you're new to crypto or you have a friend who is, this one's for you. Happy to answer any questions 🛡️
