About this extension
Jogo: Your Ultimate Web3 Security Companion

Navigating the Web3 ecosystem shouldn't mean putting your assets at constant risk. Jogo is a lightweight, real-time security extension designed to protect crypto users from malicious dApps, phishing websites, and dangerous smart contract transactions.
Unlike traditional security tools that expect you to be a blockchain expert, Jogo works seamlessly in the background and translates complex on-chain risks into simple, human-readable alerts powered by AI.

Key Features:
Real-Time Domain Verification Jogo instantly checks every website you visit against extensive, continuously-updated blacklists (including ScamSniffer, OpenPhish, and CryptoScamDB). If you land on a typosquatted domain, a newly registered suspicious site, or a known phishing trap, Jogo will immediately block the interface and warn you before you connect your wallet.

Transaction Interception & Simulation Never sign a blind transaction again. Jogo acts as a secure proxy between your browser and your wallet (MetaMask, Rabby, etc.). Before any transaction or signature is executed, Jogo intercepts the request, simulates the calldata via our backend, and predicts exactly what will happen to your assets.

AI-Powered Explanations Forget reading raw hex codes. Jogo leverages advanced AI models (Llama-3) to analyze the transaction signals and provide a concise, non-technical explanation of the risk level. You'll know exactly if a transaction is safe, low risk, or critical.

Fast and Non-Intrusive Built with strict latency budgets, Jogo ensures that your Web3 experience remains lightning fast. If an analysis takes too long, our smart fail-open design ensures your browser never hangs, putting you back in control instantly.

Privacy First: Your privacy matters. Jogo only evaluates transaction payloads (calldata, contract addresses, and URLs) to provide security insights. We do not require your private keys, and we do not collect unnecessary telemetry data.

Take back your peace of mind in Web3. Install Jogo today and surf the decentralized web with confidence.
