# Integrating with @solana/kit

<View title="React" icon="react">
  Privy's **ConnectedStandardSolanaWallet** object is fully compatible with popular web3 libraries for interfacing wallets and signing transactions and messages, such as [`@solana/kit`](https://www.solanakit.com/).

  Read below to learn how to best integrate Privy alongside `@solana/kit`.

  First find your desired wallet from the **`wallets`** array:

  ```tsx theme={"system"}
  import {useWallets} from '@privy-io/react-auth/solana';

  const {wallets} = useWallets();
  const wallet = wallets[0]; // Replace this with your desired wallet
  ```

  ## Signing Transactions

  Transactions generated by `@solana/kit` can be signed using the `signTransaction` method from the `useStandardSignTransaction` hook.

  ```tsx theme={"system"}
  import {
    pipe,
    createTransactionMessage,
    setTransactionMessageFeePayer,
    setTransactionMessageLifetimeUsingBlockhash,
    appendTransactionMessageInstructions,
    compileTransaction,
    createNoopSigner,
    createSolanaRpc,
    getTransactionEncoder
  } from '@solana/kit';
  import {getTransferSolInstruction} from '@solana-program/system';
  import {useStandardSignTransaction} from '@privy-io/react-auth/solana';

  const {signTransaction} = useStandardSignTransaction();

  const LAMPORTS_PER_SOL = 1_000_000_000;

  const transferInstruction = getTransferSolInstruction({
    amount: LAMPORTS_PER_SOL * 1,
    destination: address(to),
    source: createNoopSigner(address(wallet.address))
  });

  const {getLatestBlockhash} = createSolanaRpc('YOUR_SOLANA_RPC_URL');
  const {value: latestBlockhash} = await getLatestBlockhash().send();

  // Create transaction
  const transaction = pipe(
    createTransactionMessage({version: 0}),
    (tx) => setTransactionMessageFeePayer(address(wallet.address), tx),
    (tx) => setTransactionMessageLifetimeUsingBlockhash(latestBlockhash, tx),
    (tx) => appendTransactionMessageInstructions([transferInstruction], tx),
    (tx) => compileTransaction(tx)
  );
  const encodedTransaction = getTransactionEncoder().encode(transaction);

  // Sign the transaction
  const signedTransaction = await signTransaction({
    transaction: new Uint8Array(encodedTransaction),
    wallet: wallet
  });
  ```

  ## Sending Transactions

  Transactions signed using the `signTransaction` method can be sent using the `signAndSendTransaction` method from the `useStandardSignAndSendTransaction` hook.

  <Info>
    Some external wallets connected via `wallet_connect_qr_solana` (such as Fireblocks) only support
    signing and do not support sign-and-send. For these wallets, `signTransaction` returns a raw
    64-byte signature instead of a fully signed transaction. See the [sign a
    transaction](/wallets/using-wallets/solana/sign-a-transaction) guide for instructions on how to
    attach the signature to the compiled transaction and send it manually.
  </Info>

  ```tsx theme={"system"}
  import {useStandardSignAndSendTransaction} from '@privy-io/react-auth/solana';

  const {signAndSendTransaction} = useStandardSignAndSendTransaction();

  const signature = await signAndSendTransaction({
    transaction: new Uint8Array(transaction), // The transaction to send, from the previous example
    wallet: wallet
  }).signature;
  ```
