# Bank Queries

> Query token balances, total supply, and denomination metadata using the bank extension

The bank extension queries token balances, supply, and denomination metadata.

```typescript theme={"system"}
import { QueryClient, setupBankExtension } from "@cosmjs/stargate";
import { connectComet } from "@cosmjs/tendermint-rpc";

const cometClient = await connectComet("https://rpc.my-chain.network");
const queryClient = QueryClient.withExtensions(cometClient, setupBankExtension);

const balance = await queryClient.bank.balance("cosmos1...", "uatom");
console.info(balance); // { denom: "uatom", amount: "1000000" }

const allBalances = await queryClient.bank.allBalances("cosmos1...");
console.info(allBalances); // [{ denom: "uatom", amount: "1000000" }, ...]
```

## Total Supply with Pagination

```typescript theme={"system"}
const firstPage = await queryClient.bank.totalSupply();
console.info(firstPage.supply);

if (firstPage.pagination?.nextKey?.length) {
  const secondPage = await queryClient.bank.totalSupply(firstPage.pagination.nextKey);
  console.info(secondPage.supply);
}
```

<Info>
  `totalSupply` is the only paginated method in the bank module. See [Pagination](/cosmjs/v0.38.x/guides/query/pagination) for the general pattern.
