import { ConnectWallet, Wallet, WalletDropdown } from '@coinbase/onchainkit/wallet'
import { Avatar, Name, Identity } from '@coinbase/onchainkit/identity'
import { base } from 'viem/chains'

function App() {
  return (
    <OnchainKitProvider
      apiKey={process.env.NEXT_PUBLIC_ONCHAINKIT_API_KEY}
