Description by TranzGuard Shield

TranzGuard Shield is a FREE real-time crypto security layer powered by Guardian v3.0, protecting your wallet at the device, network, and cloud level without ever touching your private key, seed phrase, or funds. WHAT IT PROTECTS AGAINST Address Poisoning: Detects visually similar wallet addresses designed to trick you into sending funds to an attacker. Checks first and last characters against known poisoning patterns. Malicious Signing Requests: Scans incoming dApp signing requests before you confirm. Detects hidden MAX_UINT256 unlimited spend approvals and flags them in plain language. Known Drainer Addresses: Every destination address is checked against 44 real-time threat intelligence feeds including CISA Known Exploited Vulnerabilities, OFAC US Treasury sanctions list, Chainalysis blockchain intelligence, and the TranzGuard proprietary threat database. HOW IT WORKS When you initiate a transaction in MetaMask, TranzGuard Shield intercepts the unsigned transaction payload and checks the destination address against our threat intelligence feeds. The result appears in the MetaMask confirmation window before you click confirm. Green means safe. Red means stop. WHAT WE SEE vs NEVER TOUCH We see: Public wallet address, incoming signing requests from dapps. We never touch: Your private key, seed phrase, crypto balance, wallet password, or any ability to move your funds. TranzGuard has zero custody of your assets.
