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

const endpoints = getNetworkEndpoints(Network.Testnet);
const indexerGrpcPortfolioApi = new IndexerGrpcPortfolioApi(endpoints.indexer);

const injectiveAddress = "inj...";

const portfolio = await indexerGrpcPortfolioApi.fetchAccountPortfolioBalances(
  injectiveAddress
);

console.log(portfolio);
```
