Example Implementation

import { OnchainKitProvider } from '@coinbase/onchainkit'
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}
      chain={base}
    >
      <Wallet>
        <ConnectWallet>
          <Avatar />
          <Name />
        </ConnectWallet>
        <WalletDropdown>
          <Identity hasCopyAddressOnClick />
        </WalletDropdown>
      </Wallet>
    </OnchainKitProvider>
  )
}
