ChainGuard: Wallet Risk Check

Check a crypto wallet address before you send. ChainGuard is a read-only wallet checker for Ethereum, Base, and Arbitrum. It helps you investigate public EVM addresses, understand risk signals, review token approvals, and spot possible address-poisoning patterns. WHAT YOU CAN CHECK • Explainable wallet risk signals • Active ERC-20 token approvals found in the checked window • Unlimited token allowance warnings • Possible address-poisoning patterns • Contract or externally owned account type • Balance, transaction count, and data freshness BUILT FOR CAREFUL CRYPTO USERS Use ChainGuard before transferring assets to an unfamiliar address or approving a token spender. Each report presents the available evidence and explains why a signal matters, so you can verify important details independently. PRIVATE BY DESIGN No account or wallet connection is required. Scan history and watched addresses stay on your device. ChainGuard only uses public blockchain addresses for read-only analysis. READ-ONLY. ALWAYS. ChainGuard never asks for a recovery phrase or private key. It does not connect to your wallet, sign messages, revoke approvals, or execute transactions. SUPPORTED NETWORKS • Ethereum • Base • Arbitrum IMPORTANT Blockchain risk data can be incomplete or change over time. No detected signal guarantees that an address is safe. ChainGuard does not provide financial, investment, legal, or security advice.
