Token Approval Security

Know what you’ve approved.

Every dApp you use asks for permission. Most users sign once and forget. Attackers don’t. AllowanceGuard finds every approval, scores its risk, and lets you revoke it — across 15 chains, without surrendering custody.

How Allowance Guard Works

From connection to revocation in under a minute. Three steps, full control.

Step 01

Connect & Scan

Link your wallet or paste any address. We read public blockchain data — your keys never leave your device.

Step 02

See the Risk

Every approval gets a risk score. Unlimited amounts, unverified contracts, and known threats are flagged instantly.

Step 03

Revoke & Secure

One click to revoke. Batch multiple approvals to save gas. Every transaction signs in your own wallet.

Built for Security & Clarity

Every feature earns its place. If it doesn't make your wallet safer, it doesn't ship.

Non-Custodial by Default

Your keys stay in your wallet. We read public data, you sign every transaction. No permissions to move funds, ever.

Dashboard Built for Decisions

Every approval, risk score, and action in one view. No jargon. No hunting. See your security posture and act on it.

Real-Time Risk Scoring

Each approval is scored against live threat data — flagging unlimited amounts, unverified code, and known exploit contracts.

Batch Revoke, Less Gas

Revoke multiple approvals in one transaction. Optimised contracts keep gas costs low so security stays affordable.

Take Back

Scan your wallet in under a minute. No account needed, no keys shared.

Used by People Who Verify Everything

Traders, developers, and DAOs running AllowanceGuard on their own wallets.

Sarah Chen
DeFi Trader
Found 15 unlimited approvals I had completely forgotten about. Revoked them all in one session. The risk breakdown per approval is what sold me — I can see exactly why something is flagged.

Marcus Rodriguez
NFT Collector
I interact with 30+ dApps across Ethereum and Base. Batch revoke cleared out 40 stale approvals in one transaction. Gas cost was less than a single manual revoke would have been.

DAO Treasury Manager
Open source was non-negotiable for our DAO. We audited the code ourselves before onboarding. The team dashboard lets our multisig signers review approvals before governance votes.

Elena Volkov
Smart Contract Developer
I use the API to check allowances across Ethereum, Arbitrum, and Base in our internal tooling. Clean endpoints, predictable responses. Integrated it in an afternoon.
DK
David Kim
Portfolio Manager
Monitoring caught an approval to a contract that got exploited two days later. The alert came in before the exploit hit Twitter. That alone justified the Pro subscription.
LW
Lisa Wang
Web3 Security Educator
I walk students through AllowanceGuard in every workshop. The risk scores give them a concrete way to understand approval danger — not abstract theory, but their own wallet data.
