Configure Providers

const queryClient = new QueryClient();

export default function Providers({ children }: { children: React.ReactNode }) {
  return (
    <DynamicContextProvider
      settings={{
        environmentId: process.env.NEXT_PUBLIC_DYNAMIC_APP_ID!,
        walletConnectors: [EthereumWalletConnectors],
      }}
    >
      <WagmiProvider
        config={createConfig({
          chains: [baseSepolia],
          transports: {
            [baseSepolia.id]: http(),
          },
        })}
      >
        <QueryClientProvider client={queryClient}>
          <DynamicWagmiConnector>
            <App />
          </DynamicWagmiConnector>
        </QueryClientProvider>
      </WagmiProvider>
    </DynamicContextProvider>
  );
}

Create Smart Wallet Client

const App = () => {
  const sendTransaction = async () => {
    const { primaryWallet, handleLogOut } = useDynamicContext();

    if (!primaryWallet || !isEthereumWallet(primaryWallet)) {
      return;
    }

    const connector = primaryWallet.connector;

    if (!connector || !isDynamicWaasConnector(connector)) {
      return;
    }

    if (chain.id) {
      await primaryWallet.switchNetwork(chain.id);
    }

    const client = await primaryWallet.getWalletClient();

    client.account.signAuthorization = async (parameters) => {
      const preparedAuthorization = await prepareAuthorization(
        client,
        parameters
      );
      const signedAuthorization = await connector.signAuthorization(
        preparedAuthorization
      );

      return {
        address: preparedAuthorization.address,
        chainId: preparedAuthorization.chainId,
        nonce: preparedAuthorization.nonce,
        r: signedAuthorization.r,
        s: signedAuthorization.s,
        v: signedAuthorization.v,
        yParity: signedAuthorization.yParity,
      } as SignAuthorizationReturnType;
    };

    const smartWalletClient = await createGelatoSmartWalletClient(client, {
      apiKey: process.env.NEXT_PUBLIC_GELATO_API_KEY,
      scw: { type: "gelato" }, // use gelato, kernel, safe, or custom
    });
  };
  return (
    <div>
      <button onClick={sendTransaction}>Send Transaction</button>
    </div>
  );
};
