# Key Features
### Unified UX
Nullmask does not require any change in user behavior. Users continue using the wallets and workflows they are already accustomed to. The protocol installs as a new EVM network and operates transparently within the wallet.
### Ultimate Compatibility
Nullmask does not require any code modifications in wallets. It simply installs as a new EVM network and already works in MetaMask and any wallet that supports custom RPC endpoints and EIP-1559 transactions.
### Enhanced Security
Spending authority never leaves the wallet. Unlike other privacy protocols that extract private keys or require custom signing, Nullmask authorizes shielded transactions using standard EIP-1559 transactions. This makes the protocol more resilient to phishing attacks.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.nullmask.pro/introduction/key-features.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
