# 业务模型

FilDA包含两方面基础协议：借贷协议和质押分币协议。

\
前者借贷协议基于Compound协议修改，后者基于Harvest修改。

## 业务流程 

![](/files/-MR4Co1bSqE2g71D8LzN)

#### 基础特性 

* 资金池 
* 基于供需法则，由算法生成利率
* 浮动利率，无需协商 
* 完全透明的代币余额信息，记录所有历史利率

#### 存币 

* 汇聚用户的代币
* 实时提现
* 利息实时支付

**用例** 

* 用户进行存款，低风险获得利息收入
* dApp 应用程序、机构和交易所的代币增值

#### 借币

* 需要超额抵押 
* 无期限限制

**风险控制** 

* 借出代币价值超过安全抵押率时，抵押会优于市场利率进行清算，鼓励套利者进行套利，降低风险 

**用例**

* 快速借 utility token 进行使用。随时可借，无需等待（exchange 需要等待吃单) 
* 用户抵押持有的组合资产（多种代币）借出 ETH，进行 ICO 等投资。
* 做空

#### 账务系统

```
现金 + 借款 = 存款 + 抵押资产
```

```
Cash + Borrows = Supply + Equity
```

# 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 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.filda.io/zhong-wen/xiang-mu-jie-shao/ye-wu-mo-xing/ye-wu-mo-xing-model.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.
