Public address only. No wallet connection. Nothing to sign.
Why revoke at all?
Every approval you've ever signed is still active until you revoke it. If a contract you approved turns malicious or gets exploited, it can move that token without asking you again. Revoking closes the door.
Step 1: find your approvals
Scan your public address to list every approval across chains and see which are risky (unlimited allowances, unverified or flagged spenders). You don't need to connect a wallet to look.
Step 2: revoke the risky ones
Open the approval on revoke.cash, connect your wallet, and send a revoke transaction. You pay a small gas fee. Start with unlimited approvals to unverified or unknown contracts.
Step 3: stay ahead of new ones
Every swap, mint or bridge can add a new approval. A one-time cleanup helps, but continuous monitoring catches the next risky approval the moment it appears.
FAQ
Does revoking cost money?
Yes: a small gas fee per revoke, paid in the chain's native token. Checking your approvals is free.
Is it safe to revoke?
Yes. Revoking only removes a permission; it never moves your funds. You sign the revoke from your own wallet.
