Built a tool that tells you what you’re actually signing — before you sign it
I'm a solo founder, and I built Shield after watching too many people lose everything to a single click. Not to some sophisticated hack — to a malicious approve they couldn't read.
Here's the problem: a signature request today is a wall of hex. Your wallet shows it to you but never tells you what it actually does. So people hit "Confirm" and hope for the best.
Shield steps in before you sign:
Intercepts signature requests across ETH, Solana, TON & NEAR — right in the browser
Uses AI to decode the calldata into plain English: what you're signing, who gets access, how much
Checks the domain against known phishing lists (a fake "uniswap" lights up red)
Auto-rejects dangerous requests by rules you set — unlimited approve, transfers to flagged addresses
It's not another scanner you run after you've already been drained. It works at the exact moment of signing.
Being straight with you:
It's early and rough. There will be bugs — I'll fix them fast. It's also not free; chain nodes and AI inference cost real money, and I won't cut corners on a security tool. The Chrome extension is in Web Store review right now — happy to share a manual-install build if anyone wants it sooner.
What's next: a simple AI-assisted hot wallet for all chains, and a seedless hardware wallet that's even more secure (the tech already works).
Would love your honest take — especially what would make you not trust a tool like this. That's the feedback I need most.
