ChainGuard

ChainGuard protects your crypto wallets by scanning for dangerous token approvals across multiple blockchains.

Every time you interact with a DeFi protocol, you grant token approvals that can put your funds at risk. Forgotten unlimited approvals to unverified contracts are the #1 cause of wallet drains. ChainGuard finds them and helps you revoke them.

SCAN YOUR WALLET • Paste any wallet address to scan — no login required • Scans Ethereum, Arbitrum, Polygon, Linea, and Scroll in parallel • Detects unlimited approvals, unverified contracts, and EOA-owned deployers • Security score from 0-100 based on your approval risk profile

TRANSACTION SIMULATOR • Paste any transaction calldata before signing • See exactly what a transaction will do in plain English • Identifies approve, transfer, transferFrom, and allowance changes • Risk classification: Critical, High, Medium, Low, Safe

REAL-TIME MONITORING (Pro) • 24/7 wallet monitoring with push notifications • Alerts when approved contracts change ownership • Alerts when proxy contracts are upgraded • Peace of mind — ChainGuard watches so you don't have to

CONTRACT INTELLIGENCE • Contract age and deployment history • Owner type detection (EOA vs Multisig) • Source code verification status • Risk factor analysis for every approval

FREE TO START • 3 free wallet scans — no account needed • Upgrade to Pro for unlimited scans and real-time monitoring

ChainGuard never accesses your private keys or funds. All scanning is read-only using publicly available blockchain data.
