import { ChainGrpcOracleApi } from "@injectivelabs/sdk-ts/client/chain";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcOracleApi = new ChainGrpcOracleApi(endpoints.grpc);

const moduleParams = await chainGrpcOracleApi.fetchModuleParams();

console.log(moduleParams);
```
