What it is
Revoke.cash is an open-source token approval manager. Every "Approve" you've ever clicked in a DApp may have granted a contract indefinite permission to move your tokens — this tool shows those approvals and lets you revoke them.
When you need it
- You suspect you signed something on a fake site
- Routine hygiene: clearing stale approvals from DApps you no longer use
- Emergency damage control when tokens start disappearing from your wallet
Quick start
- Connect your wallet (it only reads your approval list; signatures are needed only when revoking).
- Scan the list for Unlimited allowances granted to contracts you don't recognize.
- Click Revoke on each — every revocation costs a small network fee.
Safety note
Revoking stops future transfers; assets already taken cannot be recovered. If your seed phrase itself is compromised, revoking won't help — move remaining funds to a brand-new wallet immediately. And verify the domain is exactly revoke.cash: this tool is heavily impersonated too.
