# Other options

> Other AIR Kit session options — set the display currency for wallet balances, transactions, and on-ramp and swap interfaces.

Session options are set in `sessionConfig` when you call `init()`, and can be changed later with `updateSessionConfig()`. For language, see [Language support](/get-started/customization/language).

## Currency

Set the optional `sessionConfig.currency` at initialization, or update it alongside the locale:

```tsx theme={null}
const updatedConfig = await airService.updateSessionConfig({ currency: "EUR" });
```

Supported currencies are `EUR` (Euro), `USD` (US Dollar), `CNY` (Chinese Yuan), `KRW` (South Korean Won), and `TRY` (Turkish Lira). Currency controls monetary display in wallet balances, transaction amounts, and on-ramp/swap interfaces. The update returns the complete `AirSessionConfig`, including locale and currency.
