SafeSign Visualizer

A visual security layer that simulates transaction outcomes and warns users of scams in plain English before they sign.

Visual security layer for crypto. Blocks wallet drains & NFT scams with easy-to-understand visual warnings. 🛡️ SafeSign Visualizer - The "Plain English" Translator for Crypto. SafeSign is not just another blacklist checker. It is a Visual Security Layer designed to protect everyday users from sophisticated blockchain scams. Instead of showing confusing hex codes, SafeSign shows you the consequence of your actions. 🚀 KEY FEATURES: ✅ Visual Time-Travel UI: When a dangerous transaction is detected, SafeSign shows you a visual timeline of exactly what will happen if you click "Sign": - Now: You click Sign. - +2 Seconds: Site gets Unlimited Access. - +10 Seconds: Wallet Drained. ✅ Smart Protection (AI-Heuristics): - Blocks Unlimited Token Approvals (ERC-20). - Blocks NFT Collection Drains (setApprovalForAll). - Blocks Gasless Permit Drains (EIP-2612): Stops fake "Sign-In With Ethereum" requests that secretly drain tokens without gas fees. - Catches new scams by analyzing transaction logic, not just known addresses. - Proactive Anti-Phishing Domain Blocker (fetches malicious URLs and blocks wallet loading) - Zero-Day Spoofed Login Detector (SIWE/EIP-4361). Blocks logins pretending to be other sites. - Power User Mode: Expandable "Technical Details" box in the Warning UI showing raw hex data and contract addresses for developers. - Auto-Pause on Localhost (DEV Mode): Automatically disables protection on localhost or 127.0.0.1. - Address Poisoning Detector: Tracks previously interacted addresses locally. If you try to send funds to a new address that looks almost identical to one you've used before, SafeSign throws a Red Warning. ✅ Community-Driven Security: - Live Blacklist: Fetches a real-time list of verified scam addresses and URLs from GitHub. - One-Click Reporting: Users can submit new scams directly from the Warning UI or extension popup UI to help protect the community. ✅ The "Green Light" System: Get instant feedback when a transaction is verified safe. A sleek green notification confirms your extension is working and the transaction is secure. ✅ Universal Compatibility: Works automatically with MetaMask, Coinbase Wallet, Rabby, Brave Wallet, and any wallet injecting window.ethereum. No setup required. 🔒 PRIVACY FIRST: - No data collection. - No tracking. - 100% Open Source. All analysis happens locally in your browser. Stop signing blindly. See the future with SafeSign. --- 🚀NEW! Version 1.5.0 Update: - Added: Auto-Pause on Localhost - SafeSign now automatically disables itself on localhost or 127.0.0.1, preventing interference with Web3 dApp development. A blue "DEV" badge appears in the toolbar when in developer mode. - Added: Address Poisoning Detector - SafeSign now tracks previously interacted addresses locally. If you try to send funds to a new address that looks almost identical to one you've used before (same first 6 and last 4 characters), it throws a Red Warning. This data is stored locally and never leaves your browser. - UI Polish: Cleaned up badge logic for manual pauses. 🚀Version 1.4.0 Update: - Added: Start/Pause Protection Toggle. Users can now temporarily pause SafeSign for advanced DeFi interactions. - Added: Dynamic Icon Switching. The toolbar icon changes color when protection is paused to warn the user. - Added: Power User Mode. Expandable "Technical Details" box in the Warning UI showing raw hex data and contract addresses for developers. - UI Polish: Sleeker borders, fixed white background plate, and refined dark mode aesthetic. 🚀 Version 1.3.0 Update: - Added Proactive Anti-Phishing Domain Blocker. SafeSign now fetches a live list of malicious websites. If a user visits a known scam site, SafeSign disables the wallet and forces a redirect to safety before they can connect. - Added Zero-Day Spoofed Login Detector (SIWE/EIP-4361). SafeSign now analyzes "Sign-In With Ethereum" requests. If a login message is pretending to be a different website (a spoof), it blocks the signature and ejects the user to safety. - Added "Escape to Safety" redirect for phishing sites. 🚀 Version 1.2.0 Update: - Permit Signature Protection (EIP-2612): We now block "gasless" sign-in scams. Scammers trick users into signing a free message to log in, which secretly gives them permission to drain your tokens. SafeSign now detects and blocks this invisible threat. - One-Click Scam Reporting: Added a "Report this Scam" button directly to the Warning UI. Users can now automatically submit malicious addresses and URLs to our community database in one click. - UI Updates: Updated the extension popup dashboard to reflect the new security features. 🚀 V1.1.0 Update: - Added Community-Sourced Blacklist: The extension now fetches a live list of verified scam addresses from GitHub. If a user tries to send funds to a known drainer, SafeSign blocks it instantly. - Added new "Known Scam Blocked" visual warning to the Time-Travel UI. - Improved engine performance for faster transaction analysis.
