# Specification

> NameGuard is a tool for identifying and preventing malicious use of ENS names.

Each name searched goes through the following checks to ensure safety across the ENS network:

* **Impersonation**: Detects names that could be trying to impersonate a different name by using similar characters.
* **Confusables**: Detects characters that can be confused with other characters.
* **Font Support**: Checks if the characters in the name are supported by commonly used fonts.
* **Invisibles**: Detects invisible characters.
* **Typing Difficulty**: Detects names that are difficult to type on some keyboards.
* **Mixed Scripts**: Detects names that contain characters from multiple scripts or alphabets.
* **Name Wrapper**: Checks if the name is supported by the new ENS Name Wrapper.
* **ENSIP-15**: Checks if the name is normalized according to ENSIP-15.
* **Punycode**: Checks if the name is compatible with Punycode encoding.
* **Unknown Labels**: Checks if the name contains unknown labels (e.g. `[0123abcd...].eth`).
* **Decentralized Name**: Checks if the name is decentralized (unruggable).
* **NameWrapper Fuses**: Checks that the NameWrapper configuration of a name is safe.
