Token Approval Checker & Revoker
See which contracts you've allowed to spend your tokens — and revoke any you don't trust. Non-custodial.
⚠️ Revoking sets the allowance to zero in a transaction you sign. Non-custodial — your keys never leave your wallet. Revoking does not move funds; it just removes a contract's permission to spend your tokens.
Why revoke token approvals?
Every time you use a DEX, bridge or dApp, you approve its contract to spend a token from your wallet — often for an unlimited amount. Those approvals stay active forever unless you revoke them. If that contract is ever exploited, your approved tokens are at risk.
Good wallet hygiene: periodically review your approvals and revoke any you no longer use or don't trust — especially unlimited ones. This tool reads your on-chain approval history, shows the still-active ones, and lets you revoke with one click.
