Features & Capabilities

ShieldForge brings the Web3 approval scanner and EIP-712 permit decoder into your browser toolbar. Self-custodial — no keys held, no custody, no relayer. Wallet signing always happens in your wallet's own UI.

What it does

🔍 Scan token approvals across 88 chains — Ethereum, Base, Arbitrum, Polygon, BNB Smart Chain, Optimism, Linea, Scroll, zkSync, Mantle, Sonic, Blast, Berachain, Cronos, Avalanche, Tron, Ronin, Etherlink, Hemi, BOB, ApeChain, Immutable zkEVM, Story, ZetaChain, Worldchain, Unichain, opBNB, Ink, and 60+ more. Risk-classified results sorted CRITICAL → LOW.
✍️ Decode EIP-712 typed-data signatures before you sign — Permit2, EIP-2612, OpenSea listings, Permit. 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 +100 chains.

Is Approval Scanner PermitDecoder Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Approval Scanner PermitDecoder requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Approval Scanner PermitDecoder is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
