## Description

CryptoShield protects you from crypto‑phishing scams in real time. It flags fake wallet pages before you enter a seed phrase, and explains exactly why a page is risky (punycode look‑alikes, shady TLDs, fake “Connect wallet” prompts, seed‑phrase requests). Works 100% locally—no tracking, no data collection.

<strong>Key features</strong>
- Real‑time detection on any site you visit
- Reason codes you can trust (domain look‑alike, punycode, risky TLDs, seed/private‑key prompts)
- On‑page red banner + optional browser notification
- Cross‑wallet heuristics (MetaMask, Coinbase, Trust Wallet, Ledger/Trezor, WalletConnect, Phantom and more)
- Privacy‑first: runs entirely in your browser; no remote servers

<strong>How detection works (heuristics)</strong>
- <strong>Domain checks:</strong> punycode (<code>xn--</code>), look‑alikes of official wallet domains, suspicious TLDs
- <strong>Content checks:</strong> seed/recovery/private‑key keywords in text/placeholders
- <strong>UI checks:</strong> deceptive “Connect wallet” or phrase‑entry prompts

<strong>Permissions used</strong>
- <code>activeTab</code> / <code>&lt;all_urls&gt;</code>: scan the current page for phishing signals
- <code>notifications</code>: show a warning if phishing is detected
- <code>storage</code>: save simple on/off settings locally

<strong>Privacy</strong>
CryptoShield does not collect, transmit, or sell any personal data. No page content, browsing history, or telemetry leaves your device. Settings are stored locally only.
