AllowanceGuard

Protect your wallet from risky token approvals with real-time risk assessment

AllowanceGuard protects your crypto wallet from dangerous token approvals before you sign a transaction. Most wallet hacks do not come from sending funds — they come from approving malicious contracts using functions like approve(), permit(), or setApprovalForAll(). Once approved, attackers can drain tokens without further permission. AllowanceGuard works in real-time by analyzing transactions before you confirm them in your wallet. Key Features: • Pre-transaction risk detection — flags suspicious approvals before signing • Smart contract analysis — identifies risky spender addresses • Real-time warnings — clear alerts when a transaction is unsafe • Works with major wallets — including MetaMask and WalletConnect • Lightweight and fast — no impact on browsing performance How it works: When you interact with a dApp, AllowanceGuard inspects the transaction request. If it detects a risky approval, it warns you instantly so you can reject it before any damage is done. Privacy-first: We do not collect personal data, wallet balances, or private keys. Only minimal transaction metadata (such as token and contract address) is analyzed for risk scoring. Free & Pro: The free version provides core protection. Pro users unlock advanced risk scoring, deeper contract analysis, and enhanced alerts. Stay safe. Stay in control. Install AllowanceGuard and protect your wallet before you sign.
