# 什么是Tron能量模式？

## **Tron能量模式**

Tron能量模式是Tron区块链中的一种资源管理机制，允许用户通过获取能量和带宽来减少或消除交易费用。Cregis提供增强版的Tron能量模式，帮助用户通过经济实惠的资源获取，平均节省30%的交易费用。每次发送Tron交易时，如果地址资源不足，系统将使用能量模式进行交易。

## **Cregis Tron能量定价**

能量费用 = 能量 X 价格（420 SUN）/ 10^6\
带宽费用 = 带宽 X 价格（1000 SUN）/ 10^6

## **在Cregis中使用Tron能量**

当用户有Tron交易需要处理时，Tron能量模式将自动激活。Cregis提供3种方式使用Tron能量：

1. **消耗地址中的Tron能量**\
   如果您的地址中有能量，系统将优先使用地址中的能量。
2. **使用账户余额购买Tron能量**\
   如果您的地址中没有能量，系统将检查您的账户USD余额。如果您的账户有足够的USD来支付此次交易的能量费用，系统会自动计算所需的USD金额。\
   请注意，账户余额只能用于团队账户。\
   发送后，您可以在“账户费用”中查看购买记录。
3. **使用TRX购买Tron能量**\
   如果您的地址中没有能量且账户余额中没有USD，您将需要使用TRX购买Tron能量。系统会自动帮助您计算所需的TRX。\
   \
   如果您的钱包中没有TRX，系统将显示“矿工费不足”的错误提示。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.cregis.com/cregis-wallet-guide/zh-cn/resources/faq/transaction/shen-me-shi-tron-neng-liang-mo-shi.md?ask=<question>&goal=<user_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 `automate deployments from our CI pipeline` 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.
