Not at all. ShieldGuard works immediately after installation without requiring wallet connectivity.
We never request wallet connections or access to your private data. Our extension solely focuses on identifying and blocking harmful websites and detecting malicious behavior before any interaction occurs.
The extension operates independently in the background, examining website addresses, contract code, and transaction patterns - all without needing any wallet permissions or access to your holdings.
Your wallet stays completely separate from our system - we have no capability to reach your funds, recovery phrases, or any confidential information.
ShieldGuard provides comprehensive protection across multiple blockchain ecosystems. Currently supported networks include Ethereum, Bitcoin, and XRP, with active development underway for Polygon, Arbitrum, and BNB Chain integration. Our phishing detection and malicious site blocking operate universally across all blockchain platforms.
Our simulation tool reveals the consequences of approving a transaction ahead of time. This enables you to spot dangers without endangering your wallet's security. The preview clearly displays both incoming and outgoing assets from the proposed transaction.
The process works by intercepting data flowing between the application and your wallet, then processing it through our isolated testing infrastructure. You'll see the predicted results shown in our extension popup.
This functionality requires zero wallet permissions. Our methodology is fully transparent with publicly available source code that anyone can review and verify independently.
ShieldGuard operates differently from standard antivirus tools. Both offer protection, yet address distinct security concerns:
• Standard antivirus solutions defend your system by preventing harmful software installations and terminating malicious processes.
• ShieldGuard shields you from cryptocurrency scams, harmful authorization requests, and fraudulent web pages.
Never. ShieldGuard will never request your recovery phrase and maintains complete zero-access to your wallet or cryptocurrency holdings.
