# Utils

Utility functions to interact with multisigs and the nomos Iframe

### isNomos

This function checks if your app is within the Iframe wrapper of nomos. It checks first if your app is within an iframe and then if that iframe is from nomos.

```typescript
import { isNomos} from "nomosjs";

console.log({isNomos: isNomos()});
```
