Usage:

1. SubstrateState's interface:

export interface ISubstrateConnection {
  socket: string;
  jsonrpc: IJsonRpc;
  keyring: Keyring | null;
  keyringState: string | null;
  api: ApiPromise | null;
  apiError: any;
  apiState: string;
  currentAccount: KeyringPair | null;
}

2.

  useSubstrateConnection = () =>
  {
    substrateConnection: ISubstrateConnection;
    setSubstrateAccount?: (acc: any) => void;
  } : ISubstrateContextProps

3. Place the <SubstrateConnectionLayout /> component at the first level:

const SubstrateConnectionLayout = dynamic(
  () =>
    import("ts-substrate-lib").then(
      (data) => data.SubstrateConnectionLayout
    ),
  {
    ssr: false,
    loading: ()=> <></>
  }
);

...

<SubstrateConnectionLayout>
  <MainLayout>{getLayout(<PageContent {...pageProps} />)}</MainLayout>;
</SubstrateConnectionLayout>

4. With the screen use useSubstrateConnection() hook, it's necessary to dynamic import

import { ScreenLayout } from '@layouts/ScreenLayout';
import dynamic from 'next/dynamic';
const AppScreen = dynamic(() => import('@screens/app').then((data) => data.AppScreen), {
  ssr: false,
});

const App: IPageComponent = () => {
  return <AppScreen />;
};

App.getLayout = (screen) => <ScreenLayout>{screen}</ScreenLayout>;

export default App;
