Attackers clone the first and last characters of your wallet address, then slip it into your transaction history. One copy-paste mistake and your funds are gone — forever.
WalletGuard combines live blockchain data with pattern-matching algorithms to catch poisoning attempts the moment they happen.
Paste any wallet address. WalletGuard checks it against a live threat database updated every 30 seconds from Etherscan and Blockchain.info.
Lookalike detection compares prefix and suffix characters. Dust attack patterns are identified from transaction history and mempool activity.
Receive a clear risk score and detailed breakdown of why an address is flagged — before you send a single satoshi.
Install the Chrome extension for always-on protection. It monitors every paste event and input field across all web pages automatically.
Powered by live data from Etherscan, Blockchain.info, and Solscan
Threat database refreshed every 30 seconds from live blockchain APIs. No stale data, no cached lists from last month.
Compares prefix and suffix characters of addresses against known-safe addresses. Catches the clones that fool human eyes.
Identifies addresses sending sub-threshold transactions across ETH, BTC and SOL — the signature pattern of poisoning campaigns.
Always-on protection injected into every webpage. Catches addresses in DEX interfaces, MetaMask confirmations, and paste events.
Full coverage across Ethereum/EVM, Solana, and Bitcoin. More chains are being added continuously.
No account needed. No data collected. The scanner runs entirely against public blockchain APIs with no tracking.
