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.

Example Scenario

ShadowGuard shows a warning:

“This message may expose your wallet to token drainers. Proceed with caution.”

You avoid clicking. Your assets are safe.
