# 如何在 Lista Lending 上创建市场

1\. 确认市场参数

* loanToken
* collateralToken
* Oracle
* Irm
* lltv

| 参数              | 类型      | 描述        |
| --------------- | ------- | --------- |
| loanToken       | address | 借款代币的合约地址 |
| collateralToken | address | 抵押代币的合约地址 |
| oracle          | address | Oracle的地址 |
| irm             | address | 利率模型的地址   |
| lltv            | uint256 | 贷款价值比率    |

注意：

* Oracle：Oracle必须实现以下方法，其中asset是代币地址。该函数应返回带有8位小数的资产价格：

```solidity
function peek(address asset) external view returns (uint256);
```

* IRM（利率模型）：必须由Lista Lending的管理者使用enableIrm启用。默认情况下，协议使用Lista Lending部署的IRM，地址如下：\[待定]
* LLTV（清算的贷款至价值比率）：也必须由Lista Lending的管理者使用enableLltv设置。用户可以从启用的LLTV选项中选择创建金库。

## 2. 创建市场

2. 填写属性 ![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXcMq245iohsignlpyM7nwuKu_qD1cEOqLodL8U7NkVi0BnVBr9F8r4uHkQG1s-waQIXMu1bHmfnhFUVjFn6mb1Nip5_w1SST32f5HIjBc1DxP0wSX7jZtG3XxXaf-3F6OHREdeReQ?key=wfz3O-Nby90_rWV7ZzqEXcEA)
3. 批准并完成！

## 3. 设置费用 \[可选]

只有管理者地址有权设置市场费用。如果未设置，则市场费用默认为0。

1）跳转到主合约地址：<https://bscscan.com/address/0x8F73b65B4caAf64FBA2aF91cC5D4a2A1318E5D8C>

2\) 填写属性，其中newFee是设置费率的参数，小数位为1e18。例如，填写100000000000000000表示10%的费率。

marketId可以从创建市场的交易中获得，其中id指的是marketId

通过在合约中传入marketId作为参数，可以通过market函数获取费率。

* 检查成功创建市场的交易
* 检查marketId
* 检查费率
