How it works
Step 1
Paste your wallet address
Keeper-chan reads only your public address and scans on-chain activity. No login, no seed phrase, no signatures required.
Step 2
We detect risky contracts
The scanner looks for dangerous approvals and contracts that can move your tokens — even when you’re offline.
Step 3
Revoke & stay safe
If we find threats, you can connect your wallet and revoke approvals directly in your wallet UI — Keeper-chan never gets access to your keys.
On-chain reality check

Crypto theft never sleeps.

Billions in value disappear every year through hacked contracts, phishing and abused token approvals. Keeper-chan helps you see if your wallet is in danger before it’s too late.

Why approvals matter
Leftover approvals = silent backdoor. Many users forget to revoke token spend limits after using dApps.
One bad contract can drain everything. If a dApp or router is compromised, attackers can use your existing approvals to move funds.
Most victims had “accepted” the risk already. Users clicked “Approve” once and forgot. Keeper-chan scans those approvals and shows you what’s risky.
Revoking is cheap insurance. A single revoke transaction can save a whole wallet. We help you find which ones to cut first.
