The FOMOEgg egg in the studio, illustrating: How do I revoke token approvals?
Short answer

Review which contracts can spend your tokens and revoke unknown or unlimited ones. It costs a small gas fee.

How to check it yourself

  1. Open a trusted approval checker and list every contract that can spend your tokens.
  2. Look for unlimited approvals or contracts you do not recognise.
  3. Revoke them one by one, and keep a little of the gas token for the fees.
