Send Transaction from Instructions with Wallet App

Sends a transaction using a wallet app (like Phantom, Solflare, etc.) instead of a local keypair. This is the recommended way to send transactions in browser environments.

Returns: Promise<string> (transaction signature)


const signature = await connection.sendTransactionFromInstructionsWithWalletApp({
  feePayer: walletApp, // TransactionSendingSigner from your wallet app
  instructions: [instruction1, instruction2],
  abortSignal: null, // Optional: AbortSignal for cancellation
});

Options

feePayer: TransactionSendingSigner - The wallet app signer to use for paying fees and signing
instructions: Array<IInstruction> - Array of instructions to include in the transaction
abortSignal: AbortSignal | null - Optional signal to abort the transaction

Examples

Send a transaction using a wallet app:


const signature = await connection.sendTransactionFromInstructionsWithWalletApp({
  feePayer: walletApp,
  instructions: [instruction1, instruction2],
});

Send a transaction with the ability to cancel:


const controller = new AbortController();
const signature = await connection.sendTransactionFromInstructionsWithWalletApp({
  feePayer: walletApp,
  instructions: [instruction1, instruction2],
  abortSignal: controller.signal,
});
 
// To cancel the transaction:
controller.abort();
