# 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.

On Ethereum, $NEX also exists as an ERC-20.

#### USDX *(In Development)*

USDX will be the margin and quote currency of the Nexus Exchange.

Traders will use USDX to open positions and settle trades.

USDX is in development in collaboration with M0 Protocol.

#### Bridging

$NEX will move between Nexus, Ethereum and Binance Smart Chain (BSC) via the canonical NEX bridge.

A Hyperlane Warp Route is available from Ethereum Mainnet to Binance Smart Chain (BSC). NEX is locked on Ethereum and a synthetic NEX is minted on BSC (and vice versa).

## 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.
