tip

To maintain better security, it is recommended that you:

  1. Regularly check approvals : Periodically (e.g., monthly) review your token approvals, especially after frequent interactions with new contracts or dApps.
  2. Revoke unused authorizations : Immediately cancel any approvals that are outdated or no longer in use.
  3. Carefully review new approvals : Thoroughly review new token approvals to avoid setting excessively high approved limits.
