# Mint

查询链上 mint 模块的示例代码片段。

## 使用 gRPC

### 获取 mint 模块相关参数

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcMintApi = new ChainGrpcMintApi(endpoints.grpc);

const moduleParams = await chainGrpcMintApi.fetchModuleParams();

console.log(moduleParams);
```

### 获取通胀率

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcMintApi = new ChainGrpcMintApi(endpoints.grpc);

const inflation = await chainGrpcMintApi.fetchInflation();

console.log(inflation);
```

### 获取年度供应量

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcMintApi = new ChainGrpcMintApi(endpoints.grpc);

const annualProvisions = await chainGrpcMintApi.fetchAnnualProvisions();

console.log(annualProvisions);
```
