# 代币与跨链桥

## NEX

NEX 是 Nexus 区块链的原生代币，gas 以 NEX 支付。WNEX 是 NEX 在 Nexus 区块链上的封装 ERC-20 版本；在以太坊上，NEX 同样以 ERC-20 形式存在。详情请参阅 [NEX](/exchange-layer-1/zh-cn/nex-token/tokens-and-bridges/usdnex.md)。

## USDX *（开发中）*

USDX 将成为 Nexus Exchange 的保证金币种和计价币种。交易者将使用它开仓和结算交易。它正在与 M0 Protocol 合作开发中。

## 跨链

NEX 通过两种机制在不同链之间转移：

* **NEX 官方跨链桥**连接 Nexus 区块链与以太坊。
* **Hyperlane Warp Route** 连接以太坊与币安智能链（BSC）：NEX 在以太坊上被锁定，同时在 BSC 上铸造合成 NEX。

合约地址和分步操作说明请参阅[跨链](/exchange-layer-1/zh-cn/nex-token/tokens-and-bridges/bridging.md)。

## 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/exchange-layer-1/zh-cn/nex-token/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.
