AllowanceGuard by AllowanceGuard

AllowanceGuard protects your crypto wallet from dangerous token approvals before you sign a transaction.

Most wallet exploits do not come from sending funds, but from approving malicious smart contracts using functions such as approve(), permit(), or setApprovalForAll(). Once approved, these contracts can move tokens without further confirmation.

AllowanceGuard analyzes transactions in real time and alerts you before you sign anything risky.

Key Features:

• Pre-transaction risk detection
• Smart contract and spender analysis
• Real-time warning alerts
• Works with popular wallets such as MetaMask
• Lightweight and fast

How it works:

When you interact with a decentralized application, AllowanceGuard inspects the transaction request. If a risky approval is detected, you receive an immediate warning so you can reject it.

Privacy-first:

No personal data, private keys, or wallet balances are collected. Only minimal transaction metadata (token address, spender address, chain ID) is analyzed for risk scoring.

Free and Pro:

The free version provides core protection. Pro users unlock advanced risk detection and enhanced alerts.
