Argus catches dangerous signature requests before your wallet ever sees them. It knows what Permit2 exploits, fake permits, and shady approvals look like.
We watch for the same tricks drainers use to steal wallets. Here's what we catch.
The signature that drains entire wallets in one click. Permit2 lets attackers take multiple tokens at once. This is how most people lose everything in 2024-2025.
These permits don't need prior approvals. Fresh wallet? Doesn't matter. One signature and your tokens are gone.
Flags risky approvals before you sign. Unknown contract? We'll let you know.
eth_sign hides what you're signing. We block it completely.
Uniswap, OpenSea, and other legit protocols won't trigger warnings.
See everything Argus has blocked or flagged.
Free tools to verify contracts. See how old they are, if they're verified, and if anything looks off.
Runs quietly in the background. You won't notice it until something sketchy shows up.
Sits between you and your wallet. Every signature request goes through Argus first.
Breaks down the request. Looks for Permit2, native permits, and known attack patterns.
Scores the risk. Critical, High, or Medium based on what could happen if you sign.
Shows you what's wrong. You decide whether to block it or let it through.
No account needed. Works on Chrome, Brave, Edge, or any Chromium browser.
Still in beta. Argus adds a layer of protection, but always double-check what you're signing. Found a bug? Let us know on GitHub.
