# Auction

查询链上 auction 模块的示例代码片段。

## 使用 gRPC

### 获取模块参数，如拍卖周期

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcAuctionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcAuctionApi = new ChainGrpcAuctionApi(endpoints.grpc);

const moduleParams = await chainGrpcAuctionApi.fetchModuleParams();

console.log(moduleParams);
```

### 获取当前拍卖状态，如最新轮次

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcAuctionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcAuctionApi = new ChainGrpcAuctionApi(endpoints.grpc);

const latestAuctionModuleState = await chainGrpcAuctionApi.fetchModuleState();

console.log(latestAuctionModuleState);
```

### 获取当前拍卖篮子并获取最高出价者和金额等信息

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcAuctionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcAuctionApi = new ChainGrpcAuctionApi(endpoints.grpc);

const currentBasket = await chainGrpcAuctionApi.fetchCurrentBasket();

console.log(currentBasket);
```
