Plain-text breakdown of domain, message, primary type. Warnings when value = 2^256-1 (unlimited allowance). - 🛡️ **Phishing watch on dApps** — when a dApp asks for a typed-data signature with a permit-shaped payload, a non-blocking floating banner offers a one-click decode. Excludes banking domains, Google login, ShieldForge web app. - 📊 **Local scan history** — past scans stored in `chrome.storage.local`, never uploaded. - 🔔 **Weekly hygiene reminder** (opt-in) — browser notification if your last scan showed unrevoked CRITICAL approvals more than a week ago. - 🌍 **5 languages** — English, Español, 日本語, Русский, 中文 — auto-detected from browser locale. ### Privacy We never read wallet keys or send PII. The scanner API receives the wallet address you scan (a public on-chain identifier) along with standard HTTP request metadata. Full policy at https://shieldforge.xyz/privacy. ### Why we built this Most token-approval drains in 2026 happen via blind EIP-712 signatures. Standard wallet UIs show "Sign typed data?" without explaining what it means. ShieldForge fills that gap — decode before you sign, audit before you forget, revoke before it costs you. Backed by the same scanner running at https://shieldforge.xyz across +95 chains. A longer explanation of features, functionality, and other relevant information.
