Project status
AllowanceGuard has been retired.
The wallet-approval scanner, REST API, and browser extension are no longer operating. The project is discontinued and no longer maintained. What remains — and stays free and public — is the writing: 36 articles on token approvals, Permit2, revocation, and wallet security.
Need to check or revoke approvals right now?
AllowanceGuard can no longer do this for you. Use an independent, maintained tool such as Revoke.cash (not affiliated with AllowanceGuard), or a maintained wallet such as Rabby. Do not rely on any AllowanceGuard endpoint, extension, or cached page for live security decisions.
