# Balance And Transaction History

### Asset Balances

You can also use the SDK instance (`zkfi`), to query asset balances of the shielded account you initialized the SDK with:

```typescript
const balances: Record<number, bigint> = zkfi.getBalances();

// Output:
// {
//   65537: 2000000000000000000n,
//   65538: 32000000000000000000n,
//        .
//        .
//        .
// }
```

The returned output is a mapping from the asset id to the balance value.

### Transaction History

SDK instance can also be utilized to query transaction history list with:

```typescript
const fromBlock = 10820000;
const toBlock = 10720000;

const history = zkfi.getTransactionHistory(fromBlock, toBlock);
```
