console.log('Holds:', result.holds.length);
```

### identifier

## Return Value

`Promise<QueryBalanceDetailsResult>`

```ts
interface QueryBalanceDetailsResult {
  totalBalance: BigNumber;      // total CSPR including holds
  availableBalance: BigNumber;  // spendable balance
  holds: BalanceHold[];         // locked amounts
}
```

- `availableBalance = totalBalance - sum(holds)`
- Use `availableBalance` for withdrawal calculations
- Holds occur from staking, smart contract locks, etc.
