  if (status === 'Connecting') return <div>Connecting...</div>;
  if (status === 'NotConnected') return <div>Not connected</div>;

  return (
    <div>
      <p>Network: {network.name}</p>

      <p>Connected: {status === 'Connected' ? 'Yes' : 'No'}</p>
    </div>

**Access specific network client:**

```tsx
const { client: polkadotClient, status } = usePolkadotClient('polkadot');
const { client: kusamaClient } = usePolkadotClient('kusama');
