Some Solana methods require you to pass a Solana WalletAccount object. If you want to check if a certain wallet account is a Solana WalletAccount, you can use the isSolanaWalletAccount helper method to avoid type errors. 
import { isSolanaWalletAccount, signAndSendTransaction } from '@dynamic-labs-sdk/solana';

const sendTransaction = async (walletAccount, transaction) => {
  if (!isSolanaWalletAccount(walletAccount)) {
    throw new Error('This wallet account is not a Solana wallet account');
  }

  const { signature } = await signAndSendTransaction({ transaction, walletAccount });

  // ...
}

React

isSolanaWalletAccount is a synchronous type guard that works the same in React. Use it inside callbacks or to filter wallet accounts reactively: 
import { isSolanaWalletAccount } from '@dynamic-labs-sdk/solana';
import { useWalletAccounts } from '@dynamic-labs-sdk/react-hooks';

function SolanaWalletDisplay() {
  const walletAccounts = useWalletAccounts();
  const solanaAccount = walletAccounts.find(isSolanaWalletAccount);

  if (!solanaAccount) return <p>No Solana wallet connected</p>;
  return <p>Solana address: {solanaAccount.address}</p>;
}
