Send a Versioned Solana Transaction

const transferTransaction = new VersionedTransaction(messageV0);

const signer = await primaryWallet.getSigner();

await signer
  .signAndSendTransaction(transferTransaction)
  .then((res: any) => {
    console.log(
      `Transaction successful: https://solscan.io/tx/${res.signature}?cluster=devnet`,
    );

  .catch((reason: any) => {
    console.error(reason);
  });

Simulate a Transaction

Before sending a transaction, you can simulate it to preview the effects and validate that it will succeed. Transaction simulation shows all asset transfers involved in the transaction.

Transaction simulation uses the currently selected primary wallet. Make sure the user has a wallet connected before attempting to simulate a transaction.
