# Token Approvals

> **Given the increasing number of hacks targeting blockchain projects and users, Krystal provides the Token Approvals tool to help you quickly revoke approvals to any malicious contract addresses.**

**Step 1: Navigate to "Token Approvals" page**

You can access the "Token Approvals" page by hovering over "More" in the navigation bar and click on "Token Approvals".
