ShadowGuard
ShadowGuard is your first line of defense in the Web3 world. It's a lightweight, invisible browser extension that actively scans websites and decentralized apps (DApps) for wallet-draining threats, phishing scripts, and malicious smart contracts before they can steal your funds.
“ShadowGuard doesn’t just protect. It predicts and prevents.”
The Problem
In Web3, clicking a single malicious signature can:
Drain your entire wallet
Approve infinite token transfers
Steal your NFTs or stablecoins
These scams don’t always look suspicious — they can appear as friendly popups, “Connect Wallet” buttons, or even official-looking websites.
How ShadowGuard Works
ShadowGuard operates silently in the background, monitoring each interaction you have with DApps and websites.
Key Features:
✅ Real-time detection of dangerous wallet calls like
personal_sign
,eth_sendTransaction
, and malicious contract approvals.🚨 Warning banners before you approve risky actions.
📜 Readable summaries of what a signature actually means (e.g., “This message gives unlimited token access”).
🕵️ Invisible detection — sites can’t detect that ShadowGuard is running.
🗂️ Interaction history — grouped by site, with timestamps and actions.

You avoid clicking. Your assets are safe.
