# Tokens and Bridges

## NEX

NEX is the native token of the Nexus blockchain; gas is paid in NEX. WNEX is the wrapped ERC-20 version of NEX on the Nexus blockchain, and on Ethereum NEX also exists as an ERC-20. See [NEX](/network/building-on-nexus/tokens-and-bridges/usdnex.md) for details.

## USDX *(In Development)*

USDX will be the margin and quote currency of the Nexus Exchange — traders will use it to open positions and settle trades. It is in development in collaboration with M0 Protocol.

## Bridging

NEX moves across chains through two mechanisms:

* The **canonical NEX bridge** connects the Nexus blockchain and Ethereum.
* A **Hyperlane Warp Route** connects Ethereum and Binance Smart Chain (BSC): NEX is locked on Ethereum and a synthetic NEX is minted on BSC.

See [Bridging](/network/building-on-nexus/tokens-and-bridges/bridging.md) for contracts and step-by-step instructions.

## 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 current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nexus.xyz/network/building-on-nexus/tokens-and-bridges.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
