/*

import dynamic from "next/dynamic";
const WidgetWrapper= dynamic(() => import("@ensofinance/uniswap-migrator").then(mod => mod.WidgetWrapper), {
    ssr: false,
}); 
*/

function App() {
  return (
    <div>
      <h1>My DeFi App</h1>
      <WidgetWrapper apiKey="YOUR_ENSO_API_KEY" />
    </div>
  );
}

export default App;

      <WidgetWrapper
        apiKey="YOUR_ENSO_API_KEY"
        outTokens={[
