How Allowance Guard Works

Three simple steps to secure your wallet and protect your assets.

Step 01

Connect & Scan

Connect your wallet securely. We read public blockchain data only. Your private keys and funds remain completely under your control.

Step 02

Analyze & Understand

Get a clear risk assessment instantly. We analyze every allowance and flag risky, unlimited, or malicious approvals with advanced intelligence.

Step 03

Act & Secure

Revoke with confidence. One-click revocation executes directly from your wallet. Batch multiple revocations to save on gas fees.

Built for Security & Clarity

Every feature is designed with one goal: keeping your assets secure.

Non-Custodial Security

Full control remains in your wallet. We never hold your keys, funds, or require any permissions to move them. Every transaction is executed directly from your wallet.

Clarity-First Dashboard

Designed to enterprise standards. See your entire security posture at a glance, with no jargon or confusion. Every piece of information is actionable and immediately understandable.

Advanced Risk Intelligence

Risk scores are powered by real-time threat data, identifying known malicious contracts and anomalous approvals. Our intelligence engine continuously updates to stay ahead of emerging threats.

Gas-Efficient Revocation

Batch revoke multiple allowances in a single transaction to save on gas fees and time. Our smart contract optimization ensures you pay the minimum possible gas costs for maximum security.
